          disclosures normally included in financial statements prepared in
          accordance with generally accepted accounting principles have been
          condensed or omitted pursuant to such rules and regulations, although
          the Company believes that the disclosures are adequate to make the
          information presented not misleading. It is suggested that these
          condensed financial statements and footnotes be read in conjunction
          with a prospectus dated November 18, 1996 issued by the Company and
          filed with the SEC on Form S-1 as part of its Registration Statement
          in respect of an issue of Senior Notes (the "Registration Statement").

     (B)  The condensed consolidated balance sheet at March 31, 1996 included
          herein has been extracted from audited financial statements; all other
          figures are unaudited. The condensed financial statements included
          herein have been reviewed by the Company's independent public
          accountants and their report is included herein as Exhibit 15.

     (C)  The unaudited pro forma condensed consolidated statement of income
          presented herein for the nine months to December 31, 1995 reflects the
          acquisition by the Company of South Western Electricity  plc ("SWEB")
          as if it had occurred as of April 1, 1995. Such unaudited pro forma
          condensed consolidated statement of income has been prepared by the
          Company based upon assumptions deemed proper by it and reflects a
          preliminary allocation of the purchase price paid for SWEB. The
          unaudited pro forma condensed consolidated  statement of income
          presented herein is shown for illustrative purposes only and is not
          necessarily indicative of the future results of operations of the
          Company or of the results of operations of the Company that would have
          actually occurred had the transaction been in effect for the period
          presented. The unaudited pro forma condensed consolidated statement of
          income has been adjusted  to reflect the acquisition as if it had
          occurred  at April 1, 1995, including increased depreciation and
          amortization,  the elimination of bid defense costs incurred by SWEB,
          and  increased  interest  expense using the assumption that the
          acquisition had been 100% funded with short-term borrowings.  A
          schedule  detailing the pro forma adjustments is included on pages
          10 and 11.
       
     (D)  The Company and SWEB utilize certain financial derivative contracts
          solely for the purpose of risk management. The Company's and SWEB's
          participation in derivative contracts has been to hedge business
          exposure in connection with fluctuations in interest rates, currency
          rates related to certain of the Company's liabilities, and electricity
          purchase costs. At December 31, 1996, the status of outstanding
          derivative contracts was as follows:

          (i)  Interest rate swaps with a notional amount of (pound)500 million,
          and currency swaps with a notional amount of (pound)300  million.
          These swaps have maturities of 2001-2012. The unrealized loss was
          (pound)20 million.

          (ii) SWEB has contracts for differences ("CFDs") to mitigate its
          exposure to  volatility in the prices of electricity purchased
          through the wholesale electricity trading market (the "Pool").
          CFDs are in place to hedge electricity purchases on approximately
          27,851 GWh through the year 2008. In fiscal year 1996,

                  SOUTHERN INVESTMENTS UK plc and SUBSIDIARIES
            NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

          SWEB purchased approximately 11,065 GWh.  Accordingly, the gains or
          losses on such contracts are deferred and recognized  as
          electricity is purchased. It is not possible to estimate the fair
          value of these contracts at present as the contract prices are
          based on future events, the effects of which currently are not
          estimable.

     (E)  The Company and SWEB are routinely party to legal proceedings arising
          in the ordinary course of business which are not material, either
          individually or in aggregate.  Neither the Company nor SWEB is a
          party to any material legal  proceedings nor is it currently aware of
          any threatened material legal proceedings. As described  below, the 
          Company is aware of an issue which could subsequently impact on SWEB.

          The Pension Ombudsman (a UK arbitrator appointed by statute) has
          issued a final determination in favor of complaints made by
          members of the Electricity Supply Pension Scheme ("ESPS")
          relating to another employer's use of the ESPS surplus to offset
          the employer's costs of the early payment of pensions as a result
          of reorganization or redundancy, together with additional
          contributions required after a valuation. Under that
          determination the Pension Ombudsman directed the employer to pay
          into ESPS the amount of that use of the surplus plus  interest.
          The Pension Ombudsman's final determination may be challenged
          through the courts and no payments are required until such a
          challenge has been  heard.  If the final determination is not
          successfully challenged, it will have an adverse effect on SWEB,
          but no assurance can be given as to the extent of that effect. It
          is not practical to make an estimate of the exposure at the
          present time.

     (F)  Solely for the convenience of the reader, pounds sterling amounts
          have been translated into US dollars at the Noon Buying Rate on 
          December 31, 1996 of $1.7123 = (pound)1.00.

     (G)  In November 1996, the Company issued $168 million 6.375% Senior Notes
          due 2001 and $332 million 6.800% Senior Notes due 2006 as described in
          the Registration Statement. In January 1997, the Company issued $82
          million subordinated debentures to a business trust formed by the
          Company.

     (H)  The Conservative Party has held power in the UK since 1979. The next
          General Election in the UK must be held no later than May 1997, and
          may be called on approximately three weeks' notice at any time before
          then. Certain senior members of the Labour party, which is the main
          opposition party, have made statements regarding policies which a
          Labour government would intend to introduce, including a windfall tax
          on excess profits of privatized  utilities and referring the whole
          electricity industry to the competition authorities. There can be no
          assurance that the policies of the UK government, by whichever party
          it is controlled, would not adversely affect the Company's financial
          position or results of operations.

     (I)  The condensed consolidated financial statements included herein have
          not been prepared in accordance with the policies of Statement of
          Financial Accounting Standards No. 71 "Accounting for the Effects of
          Certain  Types of Regulation" ("SFAS No. 71"). This pronouncement,
          under which most US electric utilities report financial statements,
          applies to entities which are subject to cost-based rate regulation.
          By contrast, SWEB is not subject to rate regulation, but, rather, is
          subject to price cap regulation and therefore the provisions of SFAS
          No. 71 do not apply. Financial statements presented in accordance with
          SFAS No. 71 often contain certain deferred items which have not been
          included in rates charged to customers in compliance with the
          respective regulatory authority rulings, but which would have been
          included in the income statement of enterprises in general under US
          GAAP. The accompanying financial statements of the Company do not
          contain such deferrals.

UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF INCOME FOR THE NINE MONTHS
ENDED DECEMBER 31, 1995

As a result of the acquisition, the basis of accounting for the Successor
Company (the Company) differs from that for the Predecessor Company (SWEB). The
condensed consolidated financial statements of the Predecessor Company are
presented on a historical cost basis while the consolidated financial statements
of the Successor Company reflect the acquisition under the purchase method of
accounting. Under the purchase method of accounting, fair value was assigned to
the assets and liabilities of SWEB at the date the Company acquired effective
control of SWEB. Goodwill was created to the extent the purchase price exceeded
the difference between the fair value of SWEB's assets and fair value of its
liabilities.

The following unaudited pro forma statement of income from continuing operations
is based upon the consolidated statement of income for the period from inception
(June 23, 1995) to December 31, 1995 of the Successor Company and the
consolidated statement of income of the Predecessor Company for the period from
April 1, 1995 to September 17, 1995, adjusted to reflect the items described in
notes (1) to (5) below as if the purchase business combination had occurred at
the beginning of the period.

                  SOUTHERN INVESTMENTS UK plc and SUBSIDIARIES
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  RESULTS OF OPERATIONS AND FINANCIAL CONDITION

             THIRD FISCAL QUARTER 1997 vs. THIRD FISCAL QUARTER 1996
                                       AND
              FISCAL YEAR-TO-DATE 1997 vs. FISCAL YEAR-TO-DATE 1996


INTRODUCTION

The Company is a wholly-owned subsidiary of Southern Investments UK Holdings
Limited, of which 75% is owned indirectly by Southern Company and 25% is owned
indirectly by PP&L Resources, Inc. The Company was incorporated as a public
limited company under the laws of England and Wales on June 23, 1995, as a
vehicle for the acquisition of SWEB, one of the 12 regional electricity
companies in England and Wales licensed to distribute, supply and, to a limited
extent, generate electricity. In September 1995, the Company gained effective
control of SWEB. The Company's sole investment and only significant asset is the
entire share capital of SWEB, which is headquartered in Bristol, England.

SWEB's two main business lines are the distribution of electricity and the
supply of electricity to approximately 1.3 million customers primarily in its
franchise area in southwest England. This area covers approximately 5,560 square
miles and has a resident population of approximately 2.8 million. It also has
ancillary business activities that support its main electricity businesses,
including electricity generation and gas supply.


RESULTS OF OPERATIONS

The revenues recorded for the franchise supply business for the pro forma nine
months ended December 31, 1995 and the nine months ended December 31, 1996 are
recognized, in part, using management estimates of the revenues which will be
permitted by the Director General of Electricity Supply to be earned during the
respective fiscal years ended March 31. Accordingly, increases in revenue,
operating income and net income between the two periods discussed below are not
necessarily indicative of the results which actually have been realized between
the pro forma nine months ended December 31, 1995 and the nine months ended
December 31, 1996 or which may actually be realized between the full fiscal
years.

Earnings

Operating income for the third quarter and year-to-date fiscal year 1997 was
(pound)39 million and (pound)90 million, respectively, compared to (pound)37
million and (pound)80 million for the corresponding periods of fiscal year 1996.
The increase in operating income of (pound)2 million in the third quarter is due
to an increase in the distribution business of (pound)2 million and ancillary
businesses of (pound)6 million, partly offset by a decrease in the supply
business of (pound)6 million. The increase in operating income of (pound)10
million for the year-to-date is due to increases in the distribution business of
(pound)5 million, in the supply business of (pound)1 million, and in ancillary
businesses of (pound)4 million.

Net income for the third quarter and year-to-date fiscal year 1997 was (pound)16

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  RESULTS OF OPERATIONS AND FINANCIAL CONDITION

1996. This reduction of (pound)6 million in net income in the third quarter was
primarily due to decreases in gains on the sale of investments of (pound)7
million and interest income of (pound)5 million, partly offset by an increase in
operating income discussed above of (pound)2 million, and a decrease in interest
expense of (pound)3 million, together with a fall in the provision for income
taxes of (pound)1 million. The increase of (pound)8 million in net income for
the year-to-date was primarily due to the increase in the operating income
discussed above of (pound)10 million, a reduction in interest expense of
(pound)16 million and an increase in other net income of (pound)1 million,
partly offset by decreases in interest income of (pound)6 million and in gains
on sale of investments of (pound)6 million, together with additional provision
for taxes of (pound)7 million.

     Revenues

Revenue increases were primarily within the supply business where revenues
increased by (pound)16 million for the quarter and (pound)57 million for the
year-to-date. This reflects SWEB's strategy of becoming more active in the
non-franchise supply market; SWEB has significantly increased the number of its
industrial and commercial customers, increasing its unit sales in the
non-franchise market by 178% and 210% for the quarter and year-to-date,
respectively.

     Cost of sales

Cost of sales primarily relate to the purchase cost of electricity. The increase
is thus largely due to the increase in sales within the non-franchise market as
discussed above, together with an increase in the average purchase cost.

     Selling, general, and administrative expense

The decrease in selling, general and administrative expenses resulted in part
from a decrease in labor costs resulting from a reduction in personnel and in
part from a decrease in the level of bad debts, together with a decrease in
certain classes of computer software development costs which were expensed
during the pro forma nine months ended December 31, 1995, but which were
capitalized in the nine months ended December 31, 1996, having satisfied the
criteria for capitalization under the Company's accounting policy.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  RESULTS OF OPERATIONS AND FINANCIAL CONDITION


     Interest income

A reduction in cash balances has resulted in a reduction in interest income.

     Interest expense

Interest expense for the pro forma nine months ended December 31, 1995 reflects
interest expense recorded in connection with the acquisition as if the
acquisition had occurred on April 1, 1995 and had been 100% financed with
short-term borrowings until the acquisition date of September 18, 1995 at an
interest rate of 6% per year. However, in the nine months ended December 31,
1996, the Company benefited from the conversion of (pound)500 million of debt to
equity during the second half of fiscal year 1996.

     Gain on sale of investments

The decrease is largely due to a pretax gain of (pound)7 million realized in
December 1995 in respect of the sale of a substantial portion of SWEB's equity
holding in The National Grid Group plc ("NGG"). This gain is nonrecurring in
nature as it is the result of changes in circumstances after the fair valuation
of the investment in NGG resulting from the application of APB No. 16 which
valuation was finalized shortly after the date of acquisition.

     Provision for income taxes

The movements in the provision for income taxes result from the change in pretax
income.

Future Earnings Potential

The results of operations discussed above are not necessarily indicative of
future earnings potential. The level of future earnings depends on numerous
factors ranging from the success of the implementation of reorganisation plans
to the level of energy sales growth in the electricity supply business.

The largest portion (approximately 85%) of SWEB's operating income is derived
from its distribution business -- essentially the operation and maintenance of
the electricity network in its franchise area of the southwest of England. SWEB
is the only distributor of electricity in this area, and management believes
that economic, environmental and regulatory factors are likely to prevent
competitors from entering this business in SWEB's franchise area.

The supply market is subject to change as it is currently partially open to
competition and competition is scheduled to be extended to the remaining
customers (largely domestic and small commercial) after March 31, 1998.

Reference is made to Notes (D), (E) and (H) in the "Notes to the Condensed
Financial Statements" herein for discussion of various contingencies and other
matters which may affect future earnings potential.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  RESULTS OF OPERATIONS AND FINANCIAL CONDITION

FINANCIAL CONDITION

Overview

The major change in the Company's financial condition during the nine months to
December 31, 1996 was the addition by SWEB of approximately (pound)54 million
property, plant, and equipment, largely in respect of the distribution network.
The funds for these additions were derived primarily from operations. It is
expected that SWEB's capital requirements in the foreseeable future for its
investment in property, plant, and equipment will be met by cash generated from
its operating activities.

Demand for electricity in Great Britain, in general, and in SWEB's franchise
area, in particular, is seasonal, with demand being higher in the winter months
and lower in the summer months. SWEB balances the effect of this and other
cyclical influences on its working capital needs with drawings under its
available credit facilities.

The Company's sole investment and only significant asset is the entire share
capital of SWEB. The Company is therefore dependent upon dividends from SWEB for
its cash flow. SWEB can make distribution of dividends to the Company under
English law to the extent that it has distributable reserves, subject to the
retention of sufficient financial resources to conduct its supply and
distribution businesses as required by its regulatory license. The Company
believes that sufficient distributable reserves will exist at SWEB to allow for
any and all cash flow generated at SWEB through operations to be distributed to
the Company through dividends to the Company.

Financing Activities

In November 1996, the Company issued $500 million Senior Notes in the US, the
proceeds of which were used to reduce short-term bank loans in the UK. $168
million of the Senior Notes are due for redemption in 2001 and $332 million in
2006. The Company entered into currency swap transactions that effectively
convert the US dollar obligations of the Senior Notes into pounds sterling
obligations, with a nominal value of (pound)300 million.

Sources of Capital

In January 1997, Southern Investments UK Capital Trust I (the "Trust"), a
statutory business trust formed under the laws of the State of Delaware and
established for the sole purpose of issuing its own securities (the "Trust
Securities") and investing the proceeds thereof in the 8.23% subordinated
debentures issued by the Company and scheduled to mature on February 1, 2027,
sold $82 million of its 8.23% Trust Securities. The Company guarantees the
Trust's obligations under the Trust Securities. The proceeds received by the
Company from the sale of the subordinated debentures were used to repay
short-term bank loans. The Company entered into currency swap transactions that
effectively convert the US dollar obligations of the subordinated debentures
into pounds sterling obligations, with a nominal value of (pound)50 million.

To meet short-term cash needs and contingencies, the Company and SWEB together
had at December 31, 1996 approximately (pound)2 million of cash and cash
equivalents and (pound)149 million of unused committed lines of credit with
banks. At December 31, 1996 the Company and SWEB together had short-term debt of
(pound)332 million largely payable to banks.
