Disclosure Of Basis Of Preparation And Significant Accounting Policies [Abstract]
Basis of preparation and accounting policies	Note 1: Basis of preparation and accounting policies These condensed consolidated half-year financial statements as at and for the period to 30 June 2024 have been prepared in accordance with International Accounting Standard 34 (IAS 34), Interim Financial Reporting as issued by the International Accounting Standards Board (IASB) and comprise the results of Lloyds Banking Group plc (the Company) together with its subsidiaries (the Group). They do not include all of the information required for full annual financial statements and should be read in conjunction with the Group’s consolidated financial statements as at and for the year ended 31 December 2023 which were prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the IASB. Copies of the 2023 annual report on Form 20-F are available on the Group’s website. The UK Finance Code for Financial Reporting Disclosure (the Disclosure Code) sets out disclosure principles together with supporting guidance in respect of the financial statements of UK banks. The Group has adopted the Disclosure Code and these condensed consolidated half-year financial statements have been prepared in compliance with the Disclosure Code’s principles. Terminology used in these condensed consolidated half-year financial statements is consistent with that used in the Group’s 2023 annual report on Form 20-F. The directors consider that it is appropriate to continue to adopt the going concern basis in preparing these condensed consolidated half-year financial statements. In reaching this assessment, the directors have taken into account the uncertainties affecting the UK economy and their potential effects upon the Group’s performance and projected funding and capital position; the impact of further stress scenarios has also been considered. On this basis, the directors are satisfied that the Group will maintain adequate levels of funding and capital for the foreseeable future. The Group’s accounting policies are consistent with those applied by the Group in its financial statements for the year ended 31 December 2023 and there have been no changes in the Group’s methods of computation. The IASB has issued a number of minor amendments to IFRSs that are relevant to the Group effective 1 January 2024, including IFRS 16 Lease Liability in a Sale and Leaseback , IAS 1 Non-current Liabilities with Covenants , and IAS 1 Classification of Liabilities as Current or Non-current . These amendments have not had a significant impact on the Group. Future accounting developments The IASB has issued Amendments to the Classification and Measurement of Financial Instruments (IFRS 9 and IFRS 7) which is effective 1 January 2026 and IFRS 19 Subsidiaries without Public Accountability: Disclosures which is effective 1 January 2027. Neither the amendments nor IFRS 19 are expected to have a significant impact on the Group. The IASB has also issued IFRS 18 Primary Financial Statements which is effective 1 January 2027. The standard includes no measurement changes, and the Group is currently assessing the impact of this standard on its income statement presentation. Related party transactions The Group has had no significant related party transactions during the half-year to 30 June 2024 . Related party transactions for the half-year to 30 June 2024 are similar in nature to those for the year ended 31 December 2023 . Full details of the Group’s related party transactions for the year ended 31 December 2023 can be found in the Group’s 2023 annual report on Form 20-F.

Disclosure Of Accounting Judgements And Estimates [Abstract]
Critical accounting judgements and key sources of estimation uncertainty	Note 2: Critical accounting judgements and key sources of estimation uncertainty The preparation of the Group’s financial statements in accordance with IFRS requires management to make judgements, estimates and assumptions in applying the accounting policies that affect the reported amounts of assets, liabilities, income and expenses. Due to the inherent uncertainty in making estimates, actual results reported in future periods may be based upon amounts which differ from these estimates. Estimates, judgements and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. In preparing the financial statements, the Group has considered the impact of climate-related risks on its financial position and performance. While the effects of climate change represent a source of uncertainty, the Group does not consider there to be a material impact on its judgements and estimates from the physical, transition and other climate-related risks in the short-term. The Group’s significant judgements, estimates and assumptions are unchanged compared to those disclosed in note 3 of the financial statements included in the Group’s 2023 annual report on Form 20-F. Further information on the critical accounting judgements and key sources of estimation uncertainty for the allowance for expected credit losses is set out in note 14 .

Disclosure of operating segments [abstract]
Segmental analysis	Note 3: Segmental analysis Lloyds Banking Group provides a wide range of banking and financial services in the UK and in certain locations overseas. The Group Executive Committee (GEC) remains the “chief operating decision maker” (as defined by IFRS 8 Operating Segments ) for the Group. The segmental results and comparatives are presented on an underlying basis, the basis reviewed by the chief operating decision maker. The underlying basis is derived from the recognition and measurement principles of IFRS with the effects of the following excluded in arriving at underlying profit before tax: • Restructuring costs relating to merger, acquisition and integration activities • Volatility and other items, which includes the effects of certain asset sales, the volatility relating to the Group’s hedging arrangements and that arising in the insurance businesses, the unwind of acquisition-related fair value adjustments and the amortisation of purchased intangible assets • Los ses from insurance and participating investment contract modifications relating to the enhancement to the Group’s longstanding and workplace pension business through the addition of a drawdown feature For the purposes of the underlying income statement, operating lease depreciation (net of gains on disposal of operating lease assets) is shown as an adjustment to total underlying income. There has been no change to the descriptions of these segments as provided in note 4 to the Group’s financial statements for the year ended 31 December 2023 .

On 13 March 2024, the Group entered into a business transfer agreement with Rothesay Life plc for the sale of the Group’s bulk annuity business and to pursue the transfer of associated business assets and assumed liabilities under Part VII of the Financial Services and Markets Act 2000. A reinsurance agreement between the Group and Rothesay Life plc was signed on 30 April 2024 to materially de-risk the Group’s bulk annuity portfolio. The Part VII process is subject to approval by the High Court, through a process in which regulators and policyholders are given the opportunity to object. The Group currently expects the Part VII to take place in the second half of 2025. Upon entering into the reinsurance agreement, the Group derecognised £ 5.3 billion of financial assets which represents the reinsurance premium paid and at 30 April 2024 recognised a reinsurance contract asset of £ 5.3 billion, of which £ 0.3 billion contractual service margin was recognised. The reinsurance contract asset is presented on the Group’s balance sheet within other assets.

Financial Instruments [Abstract]
Fair values of financial assets and liabilities	Note 10: Fair values of financial assets and liabilities The valuations of financial instruments have been classified into three levels according to the quality and reliability of information used to determine those fair values. Note 21 to the Group’s financial statements for the year ended 31 December 2023 details the definitions of the three levels in the fair value hierarchy. Financial instruments classified as financial assets at fair value through profit or loss, derivative financial instruments, financial assets at fair value through other comprehensive income and financial liabilities at fair value through profit or loss are recognised at fair value. The Group manages valuation adjustments for its derivative exposures on a net basis; the Group determines their fair values on the basis of their net exposures. In all other cases, fair values of financial assets and liabilities measured at fair value are determined on the basis of their gross exposures. The following tables provide an analysis of the financial assets and liabilities of the Group that are carried at fair value in the Group’s consolidated balance sheet, grouped into levels 1 to 3 based on the degree to which the fair value is observable. There were no significant transfers between level 1 and level 2 during the period. Financial assets Level 1 £m Level 2 £m Level 3 £m Total £m At 30 June 2024 Financial assets at fair value through profit or loss: Loans and advances to banks – 3,405 – 3,405 Loans and advances to customers – 3,152 6,301 9,453 Reverse repurchase agreements – 19,816 – 19,816 Debt securities 10,589 24,999 2,286 37,874 Treasury and other bills 12 – – 12 Contracts held with reinsurers – 11,838 – 11,838 Equity shares 125,181 – 1,560 126,741 Total financial assets at fair value through profit or loss 1 135,782 63,210 10,147 209,139 Financial assets at fair value through other comprehensive income: Debt securities 14,059 13,432 51 27,542 Equity shares – – 305 305 Total financial assets at fair value through other comprehensive income 14,059 13,432 356 27,847 Derivative financial instruments 28 18,603 352 18,983 Total financial assets carried at fair value 149,869 95,245 10,855 255,969 1 Other financial assets mandatorily at fair value through profit or loss include assets backing insurance contracts and investment contracts of £ 178,559 million.

The framework covers processes for all 3 levels in the fair value hierarchy. Formal committees meet quarterly to discuss and approve valuations in more judgemental areas. Transfers into and out of level 3 portfolios Transfers out of level 3 portfolios arise when inputs that could have a significant impact on the instrument’s valuation become market observable; conversely, transfers into the portfolios arise when sources of data cease to be observable. Valuation methodology For level 2 and level 3 portfolios, there is no significant change to the valuation methodology (techniques and inputs) disclosed in the Group’s financial statements for the year ended 31 December 2023 applied to these portfolios.

Unobservable inputs Significant unobservable inputs affecting the valuation of debt securities , unlisted equity investments and derivatives are unchanged from those described in the Group’s financial statements for the year ended 31 December 2023 . Reasonably possible alternative assumptions Valuation techniques applied to many of the Group’s level 3 instruments often involve the use of two or more inputs whose relationship is interdependent. The calculation of the effect of reasonably possible alternative assumptions included in the table above reflects such relationships and is unchanged from that described in note 21 to the Group’s financial statements for the year ended 31 December 2023 .

The movement tables are compiled by comparing the position at the end of the period to that at the beginning of the year. Transfers between stages are deemed to have taken place at the start of the reporting period, with all other movements shown in the stage in which the asset is held at the end of the period. Purchased or originated credit-impaired are not transferable. Additions and repayments comprise new loans originated and repayments of outstanding balances throughout the reporting period. The Group’s impairment charge comprises impact of transfers between stages, other changes in credit quality and additions and repayments. Advances written off have first been transferred to Stage 3 and then acquired a full allowance through other changes in credit quality. Recoveries of advances written off in previous years are shown at the full recovered value, with a corresponding entry in repayments and release of allowance through other changes in credit quality.

Disclosure of allowance for expected credit losses [Abstract]
Allowance for expected credit losses	Note 14: Allowance for expected credit losses The calculation of the Group’s allowance for expected credit loss allowances requires the Group to make a number of judgements, assumptions and estimates. These are set out in full in note 24 to the Group’s financial statements for the year ended 31 December 2023 , with the most significant set out below. The table below analyses total ECL allowance by portfolio, separately identifying the amounts that have been modelled, those that have been individually assessed and those arising through the application of judgemental adjustments. Judgemental adjustments due to: At 30 June 2024 Modelled ECL £m Individually assessed £m Inflationary and interest rate risk £m Other £m Total ECL £m UK mortgages 806 – 23 142 971 Credit cards 679 – 6 15 700 Other Retail 878 – 6 58 942 Commercial Banking 992 322 – (315) 999 Other 18 – – – 18 Total 3,373 322 35 (100) 3,630 At 31 December 2023 UK mortgages 991 – 61 63 1,115 Credit cards 703 – 92 15 810 Other Retail 866 – 33 46 945 Commercial Banking 1,124 340 – (282) 1,182 Other 32 – – – 32 Total 3,716 340 186 (158) 4,084 NOTES TO THE CONDENSED CONSOLIDATED HALF-YEAR FINANCIAL STATEMENTS (UNAUDITED) (continued) Note 14: Allowance for expected credit losses (continued) Application of judgement in adjustments to modelled ECL Impairment models fall within the Group’s model risk framework with model monitoring, periodic validation and back testing performed on model components, such as probability of default. Limitations in the Group’s impairment models or data inputs may be identified through the ongoing assessment and validation of the output of the models. In these circumstances, management applies appropriate judgemental adjustments to the ECL to ensure that the overall provision adequately reflects all material risks. These adjustments are determined by considering the particular attributes of exposures which have not been adequately captured by the impairment models and range from changes to model inputs and parameters, at account level, through to more qualitative post-model adjustments. During 2022 and 2023 the intensifying inflationary pressures, alongside rising interest rates created further risks not deemed to be fully captured by ECL models which required judgemental adjustments to be added. Through the first half of 2024 these risks have largely subsided with inflation back at two per cent and the UK Bank rate now believed to have peaked. The portfolio has proven resilient to higher rates and inflation. As a result, the judgements held in respect of inflationary and interest rate risks are significantly reduced to £ 35 million (31 December 2023 : £186 million ). Other judgements continue to be applied for broader data and model limitations, both increasing and decreasing ECL. Judgemental adjustments due to inflationary and interest rate risk UK mortgages: £ 23 million (31 December 2023: £ 61 million) The Group’s ECL models for UK mortgages use UK Bank Rate as a driver of predicted defaults and were largely believed to have captured the stretch on customers due to increased interest rates. However, the combination of inflationary pressures with sharp increases to interest rates over 2023 were believed to create further risk not potentially captured by ECL models. Modest increases in new to arrears and defaults emerged in 2023, mainly driven by variable rate customers, who experienced sudden material increases in their monthly payment. Given interest rates have stabilised, inflation has reduced and experience through the first half of 2024 has been benign, this risk has reduced. A lower judgemental uplift in ECL continues to be taken in segments of the mortgages portfolio, either where inflation is expected to present a more material risk, or where segments within the model do not recognise UK Bank Rate as a material driver of predicted defaults. Credit cards: £ 6 million (31 December 2023: £ 92 million) and Other Retail: £ 6 million (31 December 2023: £ 33 million) The Group’s ECL models for credit cards and personal loan portfolios use predictions of wage growth to account for future affordability stress. As elevated inflation eroded nominal wage growth, adjustments were introduced to the econometric models to account for real, rather than nominal, income to produce adjusted predicted defaults. This impact is heavily reduced at 30 June 2024 given the model has moved into a period of low inflation, which naturally reduces the scale of adjustments in the period. Alongside these portfolio-wide in-model adjustments management had previously made an additional uplift to ECL for customers with lower income levels and higher indebtedness. This specific post- model adjustment has been released in the first half of 2024 given the improved environment and no evidence of greater deterioration in performance of this segment. Other judgemental adjustments UK mortgages: £ 142 million (31 December 2023: £ 63 million) These adjustments principally comprise: Increase in time to repossession: £ 98 million (31 December 2023: £ 106 million) The UK mortgage portfolio currently contains a larger number of customers that have been in default for a longer period than would typically be expected following pauses in litigation activity both before and during COVID-19. There is a risk that the probability of possession (PPD), and therefore ECL on these accounts is understated given this component of the model may not reflect the full impact of customers remaining in default for an extended period. Adjustments for this risk have been in place for several years, although the approach has been refined in the first half of 2024. The updated approach continues to target accounts that have been in default for more than 24 months with an arrears balance increase in the last six months. These accounts now have their PPD increased to a level based on equivalent observed performance graduated by their time in default. The change in approach has resulted in a similar level of adjustment, but now provides a mechanism which will see the adjustment naturally release as this backlog reduces. NOTES TO THE CONDENSED CONSOLIDATED HALF-YEAR FINANCIAL STATEMENTS (UNAUDITED) (continued) Note 14: Allowance for expected credit losses (continued) Adjustment for single point of loss model limitation: £ 46 million (31 December 2023: £ nil ) The current UK mortgages ECL model estimates customer level losses using a ‘single point of loss’ (SPOL) calculation, with predicted timings of defaults and subsequent repossession using average time periods. This simplification is continually assessed for any potential over or understatement of ECL compared to a more sophisticated ‘multiple points of loss’ (MPOL) modelling technique. To date, this has not shown any material difference for which an adjustment would be required. Management have been developing a new ECL model which will address this limitation, anticipated to be formally adopted later this year. However, the development activity is now suitably progressed to be leveraged in the ongoing assessment of the scale of the SPOL model simplification. This assessment indicated that the MES update in the second quarter of the year had increased the impact of the simplification up to a scale that required mitigation through a judgemental adjustment. This adjustment is expected to be released upon the final adoption of the new ECL model once it has completed appropriate internal model governance activities. Credit cards: £ 15 million (31 December 2023: £ 15 million) and Other Retail: £ 58 million (31 December 2023: £ 46 million) These adjustments principally comprise: Lifetime extension on revolving products: Credit cards: £ 60 million (31 December 2023: £ 67 million) and Other Retail: £ 10 million (31 December 2023: £ 10 million) An adjustment is required to extend the lifetime used for Stage 2 exposures on Retail revolving products from a three- year modelled lifetime, which reflected the outcome data available when the ECL models were developed, to a more representative lifetime. Incremental defaults beyond year three are calculated through the extrapolation of the default trajectory observed throughout the three years and beyond. The judgemental adjustment has reduced slightly for credit cards in the period following refinement to the discounting methodology applied. Adjustments to loss given defaults (LGDs): Credit cards: £ (50) million (31 December 2023: £ (50) million) and Other Retail: £ 18 million (31 December 2023: £ 37 million) A number of adjustments continue to be made to the loss given default assumptions used within unsecured and motor credit models. For unsecured portfolios, the adjustments reflect the impact of changes in collection debt sale strategy on the Group’s LGD models, incorporating up to date customer performance and forward flow debt sale pricing. For UK Motor Finance, the adjustment captures the latest outlook on used car prices. Commercial Banking: £ (315) million (31 December 2023: £ (282) million) These adjustments principally comprise: Commercial Real Estate (CRE) price reduction: £ 54 million (31 December 2023: £ 67 million) The material fall in CRE prices seen in late 2022 moved out of the model assumptions used to assess ECL in 2023. Given the model uses future changes in the metric as a driver of defaults and loss rates there is a continued risk that the model benefit that arises does not reflect the residual risk caused by the sustained low level of prices still apparent. Management therefore considers it appropriate to judgementally reinstate the CRE price drop within the ECL model assumptions given the materially reduced level in CRE prices could still trigger additional defaults. Within this adjustment management has refined the potential impact on loss rates through capturing updated valuations as well as stressing valuations on specific sectors where evidence suggests valuations may lag achievable levels, notably in cases of stressed sale. Corporate insolvency rates: £ (304) million (31 December 2023: £ (292) million) The volume of UK corporate insolvencies has continued to remain well above December 2019 levels, revealing a marked misalignment between observed UK corporate insolvencies and the Group’s credit performance which has been better than this. This dislocation gives rise to uncertainty over the drivers of observed trends and the appropriateness of the Group’s Commercial Banking model response which uses observed UK corporate insolvencies data to anchor future loss estimates to. Given the Group’s asset quality remains strong with low new defaults, a negative adjustment is applied by using the long-term average rate. The slightly greater negative adjustment in the period reflects the widening gap between the increasing industry level and the long-term average rate used. NOTES TO THE CONDENSED CONSOLIDATED HALF-YEAR FINANCIAL STATEMENTS (UNAUDITED) (continued) Note 14: Allowance for expected credit losses (continued) Adjustments for loss given defaults (LGDs): £ (90) million (31 December 2023: £ (105) million) Following review and monitoring on the loss given default approach for commercial exposures, ECL requires an adjustment to mitigate limitations identified in the approach which are causing loss given defaults to be inflated. These include the benefit from amortisation of exposures relative to collateral values at default and a move to an exposure- weighted approach being adopted. These temporary adjustments will be addressed through future model development. Base case and MES economic assumptions The Group’s base case economic scenario as at 30 June 2024 has been updated to reflect ongoing geopolitical and economic developments, as the slow reduction of inflationary pressures brings into view a shift to less restrictive monetary policies globally. The Group’s updated base case scenario has three conditioning assumptions: first, the wars in Ukraine and the Middle East remain geographically contained; second, the UK’s post-election economic policies retain the framework of the inflation target and fiscal rules, while allowing for an increase in both current and capital public spending; and third, the outcome of the US election broadly maintains economic policy continuity, including an unchanged position for the Federal Reserve. Based on these assumptions and incorporating the economic data published in the second quarter of 2024, the Group’s base case scenario is for a gradual expansion of economic activity and a slight rise in the unemployment rate, alongside modest changes in residential and commercial property prices. Following a gradual reduction in inflationary pressures, UK Bank Rate is expected to be lowered twice during 2024. Risks around this base case economic view lie in both directions and are largely captured by the generation of alternative economic scenarios. The Group has taken into account the latest available information at the reporting date in defining its base case scenario and generating alternative economic scenarios. The scenarios include forecasts for key variables in the second quarter of 2024, for which actuals may have since emerged prior to publication. The Group’s base case economic scenario predated the results of the UK General Election and, as such, information that has become available since the election has not been included. The Group’s approach to generating alternative economic scenarios is set out in detail in note 24 in the Group’s 2023 annual report on Form 20-F . The Group has taken into account the latest available information at the reporting date in defining its base case scenario and generating alternative economic scenarios. A small refinement was made to the Group’s approach during the first half of 2024, with alternative economic scenarios now dispersing from the base case after the balance sheet date. This is one quarter later than previously adopted reflecting the use of a base case that is now set closer to the reporting date than at the onset of IFRS 9. As a result, all scenarios include the same forecasted level for key variables in the second quarter of 2024, for which actuals may have since emerged prior to publication. For June 2024, the Group continues to judge it appropriate to include a non-modelled severe downside scenario for Group ECL calculations. The scenario is now generated as a simple average of a fully modelled severe scenario, better representing shocks to demand, and a scenario with higher paths for UK Bank Rate and CPI inflation, as a representation of shocks to supply. The combined ‘adjusted’ scenario used in ECL modelling is considered to better reflect the risks around the Group’s base case view in an economic environment where demand and supply shocks are more balanced. Scenarios by year The key UK economic assumptions made by the Group are shown in the following tables across a number of measures explained below. Annual assumptions Gross domestic product (GDP) growth and Consumer Price Index (CPI) inflation are presented as an annual change, house price growth and commercial real estate price growth are presented as the growth in the respective indices over each year. Unemployment rate and UK Bank Rate are averages over the year. Five-year average The five-year average reflects the average annual growth rate, or level, over the five-year period. It includes movements within the current reporting year, such that the position as of 30 June 2024 covers the five years 2024 to 2028. The inclusion of the reporting year within the five-year period reflects the need to predict variables which remain unpublished at the reporting date and recognises that credit models utilise both level and annual changes. The use of calendar years maintains a comparability between the annual assumptions presented.

The stage allocation for an asset is based on the overall scenario probability-weighted PD and hence the staging of assets is constant across all the scenarios. In each economic scenario the ECL for individual assessments is held constant reflecting the basis on which they are evaluated. Judgemental adjustments applied through changes to model inputs or parameters, or more qualitative post model adjustments, are apportioned across the scenarios in proportion to modelled ECL where this better reflects the sensitivity of these adjustments to each scenario. The probability-weighted view shows the extent to which a higher ECL allowance has been recognised to take account of multiple economic scenarios relative to the base case; the uplift being £ 468 million compared to £ 678 million at 31 December 2023 .

Although such changes would not be observed in isolation, as economic indicators tend to be correlated in a coherent scenario, this gives insight into the sensitivity of the Group’s ECL to gradual changes in these two critical economic factors. The assessment has been made against the base case with staging held flat to the reported probability-weighted view and is assessed through the direct impact on modelled ECL and therefore only includes judgemental adjustments applied within the model. The table below shows the impact on the Group’s ECL resulting from a 1 percentage point (pp) increase or decrease in the UK unemployment rate. The increase or decrease is presented based on the adjustment phased evenly over the first 10 quarters of the base case scenario. A more immediate increase or decrease would drive a more material ECL impact as it would be fully reflected in both 12-month and lifetime probability of defaults.

The Group retains all of the risks and rewards associated with these loans and the partnerships are consolidated fully with the loans retained on the Group’s balance sheet and the related covered bonds in issue included within debt securities in issue at amortised cost. At 30 June 2024 , the Group’s securitisation notes in issue held by external parties includes £ 23 million at fair value through profit or loss ( 31 December 2023 : £ 23 million). Those notes held internally, are secured on loans and advances to customers amounting to £ 28,454 million ( 31 December 2023 : £30,716 million ), the majority of which have been sold by subsidiary companies to bankruptcy remote structured entities. As the structured entities are funded by the issue of debt on terms whereby the majority of the risks and rewards of the portfolio are retained by the subsidiary, the structured entities are consolidated fully and all of these loans are retained on the Group’s balance sheet, with the related notes in issue included within debt securities in issue at amortised cost. Cash deposits of £ 4,067 million ( 31 December 2023 : £3,794 million ) which support the debt securities issued by the structured entities, the term advances related to covered bonds and other legal obligations, are held by the Group.

Regulatory and legal provisions In the course of its business, the Group is engaged on a regular basis in discussions with UK and overseas regulators and other governmental authorities on a range of matters, including legal and regulatory reviews and, from time to time, enforcement investigations (including in relation to compliance with applicable laws and regulations, such as those relating to prudential regulation, consumer protection, investment advice, business conduct, systems and controls, environmental, competition/anti-trust, tax, anti-bribery, anti-money laundering and sanctions). Any matters discussed or identified during such discussions and inquiries may result in, among other things, further inquiry or investigation, other action being taken by governmental and/or regulatory authorities, increased costs being incurred by the Group, remediation of systems and controls, public or private censure, restriction of the Group’s business activities and/or fines. The Group also receives complaints in connection with its past conduct and claims brought by or on behalf of current and former employees, customers (including their appointed representatives), investors and other third parties and is subject to legal proceedings and other legal actions from time to time. Any events or circumstances disclosed could have a material adverse effect on the Group’s financial position, operations or cash flows. Provisions are held where the Group can reliably estimate a probable outflow of economic resources. The ultimate liability of the Group may be significantly more, or less, than the amount of any provision recognised. If the Group is unable to determine a reliable estimate, a contingent liability is disclosed. The recognition of a provision does not amount to an admission of liability or wrongdoing on the part of the Group. During the half-year to 30 June 2024 the Group charged a further £95 million in respect of legal actions and other regulatory matters and the unutilised balance at 30 June 2024 was £ 982 million (31 December 2023 : £1,105 million ). The most significant items are outlined below. Motor commission review The Group recognised a £ 450 million provision in the fourth quarter of 2023 for the potential impact of the FCA review into historical motor finance commission arrangements and sales announced in January 2024. As disclosed in previous periods, the Group continues to receive a number of court claims and complaints in respect of motor finance commissions and is actively engaging with the FOS in its assessment of these complaints. On 10 January 2024, the FOS issued its Final Decision on a complaint relating to the Group, as well as decisions relating to other industry participants. On 11 January 2024, the FCA announced a section 166 review of historical motor finance commission arrangements and sales and plans to communicate a decision on next steps in the third quarter of 2024 on the basis of the evidence collated in the review. The FCA has indicated that such steps could include establishing an industry-wide consumer redress scheme and/or applying to the Financial Markets Test Case Scheme, to help resolve any contested legal issues of general importance. Following the FCA Motor Market Review in March 2019, the FCA issued a policy statement in July 2020 prohibiting the use of discretionary commission models from 28 January 2021, which the Group adhered to. The Group continues to believe that its historical practices were compliant with the law and regulations in place at that time. NOTES TO THE CONDENSED CONSOLIDATED HALF-YEAR FINANCIAL STATEMENTS (UNAUDITED) (continued) Note 16: Provisions (continued) As noted above, in response to both the FOS decisions and the FCA announcement the Group recognised a charge of £ 450 million in the fourth quarter of 2023. This includes estimates for operational and legal costs, including litigation costs, together with estimates for potential awards, based on various scenarios using a range of assumptions, including for example, commission models, commission rates, applicable time periods (between 2007 and 2021), response rates and uphold rates. Costs and awards could arise in the event that the FCA concludes there has been misconduct and customer loss that requires remediation, or from adverse litigation decisions. However, while the FCA review is progressing there is significant uncertainty as to the extent of misconduct and customer loss, if any, the nature and extent of any remediation action, if required, and its timing. The ultimate financial impact could therefore materially differ from the amount provided, both higher or lower. The Group welcomes the FCA intervention through an independent section 166 review and is engaging with the FCA as part of the review. HBOS Reading – review The Group continues to apply the recommendations from Sir Ross Cranston’s review, issued in December 2019, including a reassessment of direct and consequential losses by an independent panel (the Foskett Panel), an extension of debt relief and a wider definition of de facto directors. The Foskett Panel’s full scope and methodology was published on 7 July 2020. The Foskett Panel’s stated objective is to consider cases via a non-legalistic and fair process and to make its decisions in a generous, fair and common sense manner, assessing claims against an expanded definition of the fraud and on a lower evidential basis. In June 2022, the Foskett Panel announced an alternative option, in the form of a fixed sum award which could be accepted as an alternative to participation in the full re-review process, to support earlier resolution of claims for those deemed by the Foskett Panel to be victims of the fraud. Over 95 per cent of the population have now had decisions via this new process. The provision is unchanged in the first half of 2024. Notwithstanding the settled claims and the increase in outcomes which builds confidence in the full estimated cost, uncertainties remain and the final outcome could be different from the current provision once the re-review is concluded by the Foskett Panel. There is no confirmed timeline for the completion of the Foskett Panel re-review process nor the review by Dame Linda Dobbs. The Group is committed to implementing Sir Ross Cranston’s recommendations in full. Payment protection insurance (PPI) The Group has incurred costs for PPI over a number of years totalling £21,960 million . The Group continues to challenge PPI litigation cases, with mainly legal fees and operational costs associated with litigation activity recognised within regulatory and legal provisions. Customer claims in relation to insurance branch business in Germany The Group continues to receive claims from customers in Germany relating to policies issued by Clerical Medical Investment Group Limited (subsequently renamed Scottish Widows Limited), with smaller numbers of claims received from customers in Austria and Italy. The total provision made to 30 June 2024 , was £ 709 million (31 December 2023 : £ 709 million) with £ 5 million utilisation of the provision during the period, leaving an unutilised provision at 30 June 2024 of £ 69 million. The ultimate financial effect, which could be significantly different from the current provision, will be known only once all relevant claims have been resolved. Other The Group carries provisions of £ 146 million (31 December 2023 : £137 million ) in respect of dilapidations, rent reviews and other property-related matters. Provisions are also made for staff and other costs related to Group restructuring initiatives at the point at which the Group becomes committed to the expenditure; at 30 June 2024 provisions of £ 204 million (31 December 2023 : £245 million ) were held. The Group carries provisions of £ 33 million (31 December 2023 : £46 million ) for indemnities and other matters relating to legacy business disposals in prior years. Whilst there remains significant uncertainty as to the timing of the utilisation of the provisions, the Group expects the majority of the remaining provisions to have been utilised by 31 December 2028.

The total amount of this dividend is £ 662 million, before the impact of any further cancellations of shares purchased under the Group’s buyback programme (half-year to 30 June 2023 : £592 million , following cancellations of shares under the Group’s buyback programme up to the record date, was paid to shareholders). On 21 May 2024 , a final dividend in respect of 2023 of 1.84 pence per ordinary share, totalling £ 1,169 million, following cancellations of shares under the Group’s buyback programme up to the record date, was paid to shareholders. Shareholders who have joined the dividend reinvestment plan will automatically receive ordinary shares instead of the cash dividend.

Contingent Liabilities, Commitments And Guarantees [Abstract]
Contingent liabilities, commitments and guarantees	Note 19: Contingent liabilities, commitments and guarantees Contingent liabilities, commitments and guarantees arising from the banking business At 30 June 2024 contingent liabilities, such as performance bonds and letters of credit, arising from the banking business were £ 2,696 million (31 December 2023 : £2,849 million ). The contingent liabilities of the Group arise in the normal course of its banking business and it is not practicable to quantify their future financial effect. Total commitments and guarantees were £ 150,396 million (31 December 2023 : £143,319 million ) , of which in respect of undrawn formal standby facilities, credit lines and other commitments to lend, £ 81,041 million (31 December 2023 : £75,080 million ) was irrevocable. NOTES TO THE CONDENSED CONSOLIDATED HALF-YEAR FINANCIAL STATEMENTS (UNAUDITED) (continued) Note 19: Contingent liabilities, commitments and guarantees (continued) Interchange fees With respect to multi-lateral interchange fees (MIFs), the Group is not a party in the ongoing or threatened litigation which involves the card schemes Visa and Mastercard (as described below). However, the Group is a member/licensee of Visa and Mastercard and other card schemes. The litigation in question is as follows: • Litigation brought by or on behalf of retailers against both Visa and Mastercard in the English Courts, in which retailers are seeking damages on grounds that Visa and Mastercard’s MIFs breached competition law (this includes a judgment of the Supreme Court in June 2020 upholding the Court of Appeal’s finding in 2018 that certain historic interchange arrangements of Mastercard and Visa infringed competition law) • Litigation brought on behalf of UK consumers in the English Courts against Mastercard Any impact on the Group of the litigation against Visa and Mastercard remains uncertain at this time, such that it is not practicable for the Group to provide an estimate of any potential financial effect. Insofar as Visa is required to pay damages to retailers for interchange fees set prior to June 2016, contractual arrangements to allocate liability have been agreed between various UK banks (including the Group) and Visa Inc, as part of Visa Inc’s acquisition of Visa Europe in 2016. These arrangements cap the maximum amount of liability to which the Group may be subject and this cap is set at the cash consideration received by the Group for the sale of its stake in Visa Europe to Visa Inc in 2016. In 2016, the Group received Visa preference shares as part of the consideration for the sale of its shares in Visa Europe. A release assessment is carried out by Visa on certain anniversaries of the sale (in line with the Visa Europe sale documentation) and as a result, some Visa preference shares may be converted into Visa Inc Class A common stock from time to time. Any such release and any subsequent sale of Visa common stock does not impact the contingent liability. LIBOR and other trading rates Certain Group companies, together with other panel banks, have been named as defendants in ongoing private lawsuits, including purported class action suits, in the US in connection with their roles as panel banks contributing to the setting of US Dollar, Japanese Yen and Sterling London Interbank Offered Rate. Certain Group companies are also named as defendants in (i) UK-based claims, and (ii) two Dutch class actions, raising LIBOR manipulation allegations. A number of claims against the Group in the UK relating to the alleged mis-sale of interest rate hedging products also include allegations of LIBOR manipulation. It is currently not possible to predict the scope and ultimate outcome on the Group of any private lawsuits or ongoing related challenges to the interpretation or validity of any of the Group’s contractual arrangements, including their timing and scale. As such, it is not practicable to provide an estimate of any potential financial effect. Tax authorities The Group has an open matter in relation to a claim for group relief of losses incurred in its former Irish banking subsidiary, which ceased trading on 31 December 2010. In 2013, HMRC informed the Group that its interpretation of the UK rules means that the group relief is not available. In 2020, HMRC concluded its enquiry into the matter and issued a closure notice. The Group’s interpretation of the UK rules has not changed and hence it appealed to the First Tier Tax Tribunal, with a hearing having taken place in May 2023. If the final determination of the matter by the judicial process is that HMRC’s position is correct, management believes that this would result in an increase in current tax liabilities of approximately £ 950 million (including interest) and a reduction in the Group’s deferred tax asset of approximately £ 275 million. The Group, following conclusion of the hearing and having taken appropriate advice, does not consider that this is a case where additional tax will ultimately fall due. There are a number of other open matters on which the Group is in discussions with HMRC (including the tax treatment of certain costs arising from the divestment of TSB Banking Group plc) , none of which is expected to have a material impact on the financial position of the Group. NOTES TO THE CONDENSED CONSOLIDATED HALF-YEAR FINANCIAL STATEMENTS (UNAUDITED) (continued) Note 19: Contingent liabilities, commitments and guarantees (continued) FCA investigation into the Group’s anti-money laundering control framework As previously disclosed, the FCA has opened an investigation into the Group’s compliance with domestic UK money laundering regulations and the FCA’s rules and Principles for Businesses, with a focus on aspects of its anti-money laundering control framework. The Group continues to co-operate with the investigation. It is not currently possible to estimate the potential financial impact to the Group. Arena litigation claims The Group is facing claims alleging breach of duty and/or mandate in the context of an underlying external fraud matter involving Arena Television. The Group intends to contest the claims. It is not possible to estimate with certainty the potential financial impact (if any) to the Group. Other legal actions and regulatory matters In addition, in the course of its business the Group is subject to other complaints and threatened or actual legal proceedings (including class or group action claims) brought by or on behalf of current or former employees, customers (including their appointed representatives), investors or other third parties, as well as legal and regulatory reviews, enquiries and examinations, requests for information, audits, challenges, investigations and enforcement actions, which could relate to a number of issues. This includes matters in relation to compliance with applicable laws and regulations, such as those relating to prudential regulation, consumer protection, investment advice, business conduct, systems and controls, environmental, competition/anti-trust, tax, anti-bribery, anti-money laundering and sanctions, some of which may be beyond the Group’s control, both in the UK and overseas. Where material, such matters are periodically reassessed, with the assistance of external professional advisers where appropriate, to determine the likelihood of the Group incurring a liability. The Group does not currently expect the final outcome of any such case to have a material adverse effect on its financial position, operations or cash flows. Where there is a contingent liability related to an existing provision the relevant disclosures are included within note 16 .

Disclosure of ECL sensitivity to economic assumptions	The table below shows the Group’s ECL for the probability-weighted, upside, base case, downside and severe downside scenarios, with the severe downside scenario incorporating adjustments made to CPI inflation and UK Bank Rate paths. The stage allocation for an asset is based on the overall scenario probability-weighted PD and hence the staging of assets is constant across all the scenarios. In each economic scenario the ECL for individual assessments is held constant reflecting the basis on which they are evaluated. Judgemental adjustments applied through changes to model inputs or parameters, or more qualitative post model adjustments, are apportioned across the scenarios in proportion to modelled ECL where this better reflects the sensitivity of these adjustments to each scenario. The probability-weighted view shows the extent to which a higher ECL allowance has been recognised to take account of multiple economic scenarios relative to the base case; the uplift being £ 468 million compared to £ 678 million at 31 December 2023 .
