Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Responsibility for interim Financial Statements	Basis of Presentation and Responsibility for interim Financial Statements We prepared the accompanying unaudited consolidated condensed financial statements of Luxfer Holdings PLC and all wholly-owned, majority owned or otherwise controlled subsidiaries on the same basis as our annual audited financial statements. We condensed or omitted certain information and footnote disclosures normally included in our annual audited financial statements, which we prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP). Our quarterly financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2021. As used in this report, the terms "we," "us," "our," "Luxfer" and "the Company" mean Luxfer Holdings PLC and its subsidiaries, unless the context indicates another meaning. In the opinion of management, our financial statements reflect all adjustments, which are of a normal recurring nature, necessary for presentation of financial statements for interim periods in accordance with U.S. GAAP and with the instructions to Form 10-Q in Article 10 of Securities and Exchange Commission (SEC) Regulation S-X. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of our financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates, and any such differences may be material to our financial statements. Our fiscal year ends on December 31. We report our interim quarterly periods on a 13-week quarter basis, ending on a Sunday. The First Quarter, 2022, ended March 27, 2022, and the First Quarter, 2021, ended March 28, 2021. Impact of COVID-19 on the Financial Statements Demand from most end-markets we serve continues to improve in to 2022, following a period of recovery in 2021 from the adverse impact of COVID-19, which began in March 2020. The global political environment has become increasingly uncertain, combined with sharp recovery in demand and supply chain challenges, has resulted in some adverse business impacts, including increased material cost inflation on key inputs (including magnesium, aluminum and carbon fiber), labor availability issues and energy and transport cost increases. Currently, our expectation is that the impact of material and energy cost inflation and labor and transport constraints will continue at least throughout 2022, but it is our intention to pass through inflation to our customers where possible. Accounting standards issued but not yet effective None expected to be material to the Company.

Earnings Per Share [Abstract]
Earnings per share	Earnings per share Basic earnings per share are computed by dividing net income for the period by the weighted-average number of ordinary shares outstanding, net of Treasury shares and shares held in ESOP. Diluted earnings per share are computed by dividing net income for the period by the weighted average number of ordinary shares outstanding and the dilutive ordinary shares equivalents. Basic and diluted earnings per share were calculated as follows: First Quarter In millions except share and per-share data 2022 2021 Basic earnings: Net income from continuing operations $ 7.7 $ 8.6 Net (loss) / income from discontinued operations (0.1) 5.9 Net income $ 7.6 $ 14.5 Weighted average number of £0.50 ordinary shares: For basic earnings per share 27,490,741 27,658,871 Dilutive effect of potential common stock 205,377 398,452 For diluted earnings per share 27,696,118 28,057,323 Earnings / (loss) per share using weighted average number of ordinary shares outstanding: (1) Basic earnings per ordinary share for continuing operations $ 0.28 $ 0.31 Basic (loss) / earnings per ordinary share for discontinued operations $ — $ 0.21 Basic earnings per ordinary share $ 0.28 $ 0.52 Diluted earnings per ordinary share for continuing activities $ 0.28 $ 0.31 Diluted (loss) / earnings per ordinary share for discontinued operations $ — $ 0.21 Diluted earnings per ordinary share $ 0.28 $ 0.52 (1) The calculation of earnings per share is performed separately for continuing and discontinued operations. As a result, the sum of the two in any particular period may not equal the earnings-per-share amount in total. In the first quarter of 2022, basic average shares outstanding and diluted average shares outstanding were the same for discontinued operations because the effect of potential shares of common stock was anti-dilutive since the Company generated a net loss from discontinued operations. As a result, 205,377 shares combined were not included in the computation of diluted EPS for discontinued operations for the first quarter of 2022.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations Our Superform aluminum superplastic forming business operating in the U.S. was historically included in the Gas Cylinders segment. As a result of our decision to exit non-strategic aluminum product lines, we have reflected the results of operations of this business as discontinued operations in the Condensed Consolidated Statements of Income for all periods presented. We expect the sale of our Superform business to occur in 2022.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We manage our affairs so that we are centrally managed and controlled in the United Kingdom (“U.K.”) and therefore have our tax residency in the U.K. The provision for income taxes consists of provisions for the U.K. and international income taxes. We operate in an international environment with operations in various locations outside the U.K. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates. The effective income tax rate for the Quarter ended March 27, 2022, was 24.5%, compared to 21.1% for the Quarter ended March 28, 2021.

Share-based Payment Arrangement [Abstract]
Share Plans	Share Plans Total share-based compensation expense for the quarters ended March 27, 2022, and March 28, 2021, was as follows: First Quarter In millions 2022 2021 Total share-based compensation charges $ 0.2 $ 0.5 In March 2022, we issued our annual share-based compensation grants under the Luxfer Holdings PLC Long-Term Umbrella Incentive Plan. The total number of awards issued was approximately 167,400, and the weighted average fair value of options granted in 2022 was estimated to be $17.82 per share. Also in March 2022, approximately 17,000 awards were granted based on the achievement of total shareholder return targets from the period January 1, 2019, to December 31, 2021. 50% of these awards vested immediately upon grant, with the remaining 50% vesting in March 2023. The following table illustrates the assumptions used in deriving the fair value of share options granted during the First Quarter of 2022 and the year-ended December 31, 2021: First Quarter Year ended December 31, 2022 2021 Dividend yield (%) 2.27 2.27 Expected volatility range (%) 42.80 - 59.03 42.80 - 59.03 Risk-free interest rate (%) 0.04 - 0.24 0.04 - 0.24 Expected life of share options range (years) 0.50 - 4.00 0.50 - 4.00 Forfeiture rate (%) 5.00 5.00 Weighted average exercise price ($) $1.00 $1.00 Models used Black-Scholes & Monte-Carlo Black-Scholes & Monte-Carlo The expected life of the share options is based on historical data and current expectations, and is not necessarily indicative of exercise patterns that may occur. The expected volatility reflects the assumption that the historical volatility over a period similar to the life of the options is indicative of future trends, which may not necessarily be the actual outcome.

Segment Reporting [Abstract]
Segment Information	Segment Information We classify our operations into two core business segments, Gas Cylinders and Elektron, based primarily on shared economic characteristics for the nature of the products and services; the nature of the production processes; the type or class of customer for their products and services; the methods used to distribute their products or provide their services; and the nature of the regulatory environment. The Company has four identified business units, which aggregate into the two reportable segments. Luxfer Gas Cylinders forms the Gas Cylinders segment, and Luxfer MEL Technologies, Luxfer Magtech and Luxfer Graphic Arts aggregate into the Elektron segment. The Superform business unit used to aggregate into the Gas Cylinders segment but is now recognized as discontinued operations. A summary of the operations of the segments is provided below: Gas Cylinders segment Our Gas Cylinders segment manufactures and markets specialized products using composites and aluminum, including pressurized cylinders for use in various applications including self-contained breathing apparatus (SCBA) for firefighters, containment of oxygen and other medical gases for healthcare, alternative fuel vehicles, and general industrial. Elektron segment Our Elektron segment focuses on specialty materials based primarily on magnesium and zirconium, with key product lines including advanced lightweight magnesium alloys with a variety of uses across a variety of industries; magnesium powders for use in countermeasure flares, as well as heater meals; photoengraving plates for graphic arts; and high-performance zirconium-based materials and oxides used as catalysts and in the manufacture of advanced ceramics, fiber-optic fuel cells, and many other performance products. Other Other primarily represents unallocated corporate expense and includes non-service related defined benefit pension cost / credit. Management monitors the operating results of its reportable segments separately for the purpose of making decisions about resource allocation and performance assessment. Segment performance is evaluated by the chief operating decision maker, who is responsible for allocating resources and assessing performance of the operating segments as the CEO, using adjusted EBITA (1) and adjusted EBITDA, which we defined as segment income and are based on operating income adjusted for share based compensation charges; restructuring charges; acquisition and disposal related gains and costs; other charges; depreciation and amortization; and defined benefit pension credit. Unallocated assets and liabilities include those which are held on behalf of the Company and cannot be allocated to a segment, such as taxation, investments, cash, retirement benefits obligations, bank and other loans and holding company assets and liabilities. (1) Adjusted EBITA is adjusted EBITDA less depreciation. 14. Segment Information (continued) Financial information by reportable segment for the Quarters ended March 27, 2022, and March 28, 2021, is included in the following summary: Net sales Adjusted EBITDA First Quarter First Quarter In millions 2022 2021 2022 2021 Gas Cylinders segment $ 42.4 $ 36.2 $ 2.7 $ 6.0 Elektron segment 54.6 49.0 13.4 11.7 Consolidated $ 97.0 $ 85.2 $ 16.1 $ 17.7 Depreciation and amortization Restructuring charges First Quarter First Quarter In millions 2022 2021 2022 2021 Gas Cylinders segment $ 1.4 $ 0.9 $ 1.4 $ 0.5 Elektron segment 2.3 2.5 — 0.9 Consolidated $ 3.7 $ 3.4 $ 1.4 $ 1.4 Total assets Capital expenditures First Quarter December 31, First Quarter In millions 2022 2021 2022 2021 Gas Cylinders segment $ 140.0 $ 122.7 $ 0.2 $ 0.3 Elektron segment 222.5 206.5 0.8 1.2 Other 44.3 34.8 — — Discontinued operations 7.7 4.8 — — Consolidated $ 414.5 $ 368.8 $ 1.0 $ 1.5 Property, plant and equipment, net First Quarter December 31, In millions 2022 2021 United States $ 44.0 $ 46.9 United Kingdom 34.6 36.0 Canada 3.2 3.3 Rest of Europe 1.0 1.0 Asia Pacific 0.2 0.3 $ 83.0 $ 87.5 The following table presents a reconciliation of Adjusted EBITDA to net income from continuing operations: First Quarter In millions 2022 2021 Adjusted EBITDA $ 16.1 $ 17.7 Other share-based compensation charges (0.2) (0.5) Depreciation and amortization (3.7) (3.4) Restructuring charges (1.4) (1.4) Acquisition costs (0.2) (0.2) Other charges — (1.1) Defined benefits pension credit 0.4 0.6 Interest expense, net (0.8) (0.8) Provision for income taxes (2.5) (2.3) Net income from continuing operations $ 7.7 $ 8.6 14.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Committed and uncommitted banking facilities The Company had committed banking facilities of $100.0 million at March 27, 2022, and December 31, 2021. Of these committed facilities, $36.9 million was drawn at March 27, 2022, and $10.8 million at December 31, 2021. The Company also had an additional $50.0 million of uncommitted facilities through an accordian provision. The Company also has two separate uncommitted bank guarantee facilities, one denominated in GBP sterling of £0.5 million (2022: $0.7 million, 2021: $0.9 million), and one denominated in USD of $0.9 million (2021: $1.5 million). Of that dominated in GBP, £0.1 million ($0.2 million) and £0.1 million ($0.2 million) was utilized at March 27, 2022, and December 31, 2021, respectively. Of that denominated in USD, $0.9 million was utilized at March 27, 2022, and December 31, 2021, respectively. The Company also has a $4.0 million separate overdraft facility of which none was drawn at March 27, 2022, and at December 31, 2021. Contingencies In November 2018, an alleged explosion occurred at a third-party waste disposal and treatment site in Boise, Idaho, reportedly causing property damage, personal injury, and one fatality. We had contracted with a service company for removal and disposal of certain waste resulting from the magnesium powder manufacturing operations at the Reade facility in Lakehurst, New Jersey. We believe this service company, in turn, apparently contracted with the third-party disposal company, at whose facility the explosion occurred, for treatment and disposal of the waste. In November 2020, we were named as a defendant in three lawsuits in relation to the incident – one by the third-party disposal company, one by the estate of the decedent, and one by an injured employee of the third-party disposal company. At present, we have received insufficient information on the cause of the explosion. We do not believe that we are liable for the incident, have asserted such, and, therefore, do not currently expect this matter to have a material impact on the Company’s financial position or results of operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	We prepared the accompanying unaudited consolidated condensed financial statements of Luxfer Holdings PLC and all wholly-owned, majority owned or otherwise controlled subsidiaries on the same basis as our annual audited financial statements. We condensed or omitted certain information and footnote disclosures normally included in our annual audited financial statements, which we prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP). Our quarterly financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2021. As used in this report, the terms "we," "us," "our," "Luxfer" and "the Company" mean Luxfer Holdings PLC and its subsidiaries, unless the context indicates another meaning. In the opinion of management, our financial statements reflect all adjustments, which are of a normal recurring nature, necessary for presentation of financial statements for interim periods in accordance with U.S. GAAP and with the instructions to Form 10-Q in Article 10 of Securities and Exchange Commission (SEC) Regulation S-X. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of our financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates, and any such differences may be material to our financial statements.
Fiscal year	Our fiscal year ends on December 31. We report our interim quarterly periods on a 13-week quarter basis, ending on a Sunday. The First Quarter, 2022, ended March 27, 2022, and the First Quarter, 2021, ended March 28, 2021.
