National Grid Transco
2002/03 Half Year Results


                                                                                                                              Page 5




Sir John Parker, Chairman of National Grid Transco, said:


"This is a strong set of results fully in line with expectations.

"We are making excellent progress in the UK and the US.  In the UK, both our electricity and gas
businesses are outperforming against targets for reducing controllable costs, and we will exceed the
annualised £100m merger savings by March 2004.  In the US, we are ahead of schedule delivering
integration savings from our New York operation, and overall are confident of achieving a further 20%
reduction in US controllable costs.  None of this has deflected us from delivering efficient, safe and
reliable energy.

“Reflecting the strength and prospects of our business, we will pay an interim dividend of 6.86p, in
line with our aim to increase dividends per share by 5% a year in real terms until 2006.  Looking
ahead, we are confident that the skills, market position and resources of National Grid Transco will
enable us to continue to deliver shareholder value.”

Cautionary Statement

This  announcement  contains  certain  statements that are neither reported  financial  results nor other
historical  information.  These statements are  forward-looking  statements within the meaning of Section
27A of the  Securities Act of 1933, as amended,  and Section 21E of the Securities  Exchange Act of 1934,
as  amended.   Because  these   forward-looking   statements  are  subject  to  assumptions,   risks  and
uncertainties,  actual future results may differ  materially  from those  expressed in or implied by such
statements.  Many of these  assumptions,  risks and  uncertainties  relate  to  factors  that are  beyond
National  Grid  Transco's  ability to control  or  estimate  precisely,  such as delays in  obtaining  or
adverse conditions contained in regulatory  approvals,  competition and industry  restructuring,  changes
in economic conditions,  currency  fluctuations,  changes in energy market prices,  changes in historical
weather patterns,  changes in laws,  regulations or regulatory policies,  developments in legal or public
policy doctrines,  technological  developments,  the availability of new acquisition opportunities or the
timing and success of future  acquisition  opportunities.  Other factors that could cause actual  results
to differ materially from those described in this  announcement  include the ability to integrate Niagara
Mohawk and Lattice  Group plc  successfully  within  National Grid Transco or to realise  synergies  from
such  integration or the failure to retain key  management,  unseasonal  weather  impacting on demand for
electricity  and gas, the  behaviour of UK  electricity  market  participants  on system  balancing,  the
timing of amendments in prices to shippers in the UK gas market,  the  performance of the Group's pension
schemes  and the  regulatory  treatment  of  pension  costs.  For a more  detailed  description  of these
assumptions,  risks and  uncertainties,  together  with any other risk factors  please see National  Grid
Transco’s  filings with the United States  Securities  and Exchange  Commission  (and in  particular  the

NATIONAL GRID TRANSCO plc

The merger of  National  Grid Group plc  ("National  Grid) and  Lattice  Group plc  ("Lattice")  to form
National Grid Transco plc  ("National  Grid  Transco,"  "NGT" or "the Group") was completed on 21 October
2002.  The  combination of National Grid and Lattice meets the merger  accounting  criteria under UK GAAP
and  therefore  the pro  forma  financial  information  has  been  prepared  in  accordance  with  merger
accounting  principles.  Pro forma results for National Grid Transco have been prepared for  illustrative
purposes, as if the merger had taken place on 1 April 2001 (the first day of the comparative period).

Detailed  actual  results are also  included  for  National  Grid and Lattice as  separate  entities  for
completeness.  Financial  information has been provided for the main NGT business segments. We have taken
the opportunity of the merger and the first full  contribution  from Niagara Mohawk to review how best to
segment our results and have adopted a geographical  and functional  split.  We have included  additional
data on the Investors' section of our website  (www.ngtgroup.com)  to allow full  reconciliation  against
the previous National Grid and Lattice segments.


Unless otherwise indicated, numbers are stated before exceptional items, goodwill amortisation and the
impact of additional NTS auction income last year.

NATIONAL GRID TRANSCO SIX-MONTH PRO FORMA RESULTS
---------------------------------------------------------------------------------------------------------

Total turnover for the period was £4,309m.
o        National Grid's turnover  increased 52% to £3,029m,  due to the  contribution  from the New York
    operation of National Grid USA, the acquisition of which was completed on 31 January 2002.
o        Lattice's  turnover  increased 4% to £1,302m.  Turnover in Transco is  seasonal,  with the first
    half typically accounting for around 40% of annual turnover.

Total operating profit was £802m.
o        National  Grid’s  operating  profit for the period  was up £243m to £628m,  reflecting  a strong
    performance from the regulated  business in the UK, as well as the first full period  contribution of
    £206m from the New York operation.
o        Lattice’s  operating profit fell £31m to £174m due to increased  turnover being more than offset
    by the planned increase in replacement  expenditure  ("repex").  With operating costs evenly balanced
    across the year, the first half typically accounts for some 20% of operating profits.

Net interest  was £463m.  EBIT  interest  cover was 1.7 times.  Funds from  operations  cover,  excluding
repex, was 2.7 times.
o        National  Grid's net interest  increased  £129m to £282m,  due to the  inclusion  of  borrowings
    related to the New York operation.
o        Lattice's net interest rose by £17m to £181m.

Profit before tax was £339m.
o        National Grid's profit before tax was up 49% to £346m.
o        Lattice's £7m loss before tax was down from a prior period profit before tax of £41m.




NATIONAL GRID TRANSCO SIX-MONTH PRO FORMA RESULTS (continued)
---------------------------------------------------------------------------------------------------------

The tax  charge on the  profit for the period  was £92m,  representing  an  effective  tax rate of 32% on
profit before  exceptionals  and after  goodwill  amortisation.  There were no releases of prior year tax
provisions  during the period (£42m of releases in same period last year).  The tax charge  includes full
provision for deferred tax on an  undiscounted  basis,  consistent  with the Group's  ongoing  accounting
policy. On this basis:
o        National Grid's tax charge for the period was £94m.
o        Lattice's  tax  credit  for the  period  was £2m.  Prior  year  results  for  Lattice  have been
    restated  to  include a full  provision  for  deferred  taxes on an  undiscounted  basis.  Previously
    Lattice's deferred tax was reported on a discounted basis.

Profit after tax and minority interests was £244m.
o        National  Grid's profit after tax and minority  interests  was £248m,  up 21% from £205m for the
    prior period.
o        Lattice's  loss after tax and minority  interests was £4m, a decrease from a prior period profit
    of £27m.

Earnings per share were 7.9 pence for NGT, based on the pro forma  weighted  average number of shares for
National Grid Transco at 30 September 2002.
o        National Grid earnings per share increased 0.2 pence to 14.1 pence.
o        Lattice earnings per share decreased 0.9 pence to a loss of 0.1 pence.

Net exceptional charges totalled £337m (£278m after tax).
o        National Grid had exceptional net credits totalling £6m (£31m after tax).  They comprise:
-        A £127m credit (£145m after tax) in respect of Intelig and other telecom  joint  ventures.  This
         substantially  reflects  the  release of  provisions  representing  the  reversal of the Group's
         share of retained  losses  incurred  by Intelig  and other  telecom  joint  ventures  during the
         period.
-        An  exceptional  net  interest  charge of £93m  (before and after tax)  relating to our share of
         exchange losses  incurred on foreign  exchange  borrowings  included within the Group's share of
         retained losses incurred by Intelig referred to above.
-        An  exceptional  net  interest  gain of £38m  (before and after tax).  This relates to a gain on
         net monetary  liabilities of £69m as a result of the adoption of  hyper-inflationary  accounting
         in  Transener,  offset  by our share of their  exchange  losses  incurred  on  foreign  exchange
         borrowings of £31m.
-        A £12m minority  interest  charge being a share of the £38m net  exceptional  credit  related to
         Transener as shown above.
-        Merger related costs of £38m (£37m after tax).
-        US integration and UK restructuring costs of £16m (£10m after tax).

o        Lattice had exceptional charges totalling £343m (£309m after tax).  They comprise:
-        A £166m  charge  (£165m  after  tax) to write  down  fully  the  carrying  value  of its  altnet
         investments, and provide for all related liabilities at 30 September.
-        A £32m loss before and after tax arising from the sale of The Leasing Group.
-        Restructuring costs of £90m (£63m after tax).
-        Merger related costs of £67m (£61m after tax).
    Partially offset by:
-        Profit on disposal of tangible fixed assets of £12m (before and after tax).

Group net debt at 30 September was £14,162m.
o        National  Grid net debt at 30  September  fell to  £7,624m,  down £617m from the  position at 31
    March, largely a result of the depreciation of the US Dollar.
o        Lattice  net debt at 30  September  rose to  £6,538m,  up £480m from the  position  at 31 March,
    primarily due to the seasonality of Transco's revenue.


NATIONAL GRID TRANSCO SIX-MONTH PRO FORMA RESULTS (continued)
---------------------------------------------------------------------------------------------------------

Cash flow from operations was £1,197m.
o        National  Grid's  cash flow from  operations  was  £841m,  up 52% from last  year,  largely as a
    result of the addition of the New York operation.
o        Lattice's cash flow from operations was £356m, up 23% from last year.

Capital expenditure, including capitalised interest, amounted to £752m.
o        National  Grid's  capex  increased by £62m to £303m,  largely due to the  inclusion of capex for
    the New York operation.
o        Lattice's  capex  decreased  by £218m  to  £449m,  primarily  due to  planned  lower  levels  of
    investment in the high-pressure NTS and reduced investment in 186k.


Interim dividend

The Board has  declared an interim  dividend  of 6.86 pence per  ordinary  share.  The  dividend  will be
payable on 21 January 2003 to  shareholders  on the register on 6 December 2002.  This  represents a 6.2%
nominal  increase  compared  with last year's  National  Grid  payment,  in line with our aim to increase
dividends  per  ordinary  share  expressed in sterling by 5% in real terms in each  financial  year to 31
March 2006.

The dividend  per  American  Depositary  Share (ADS)  declared by the Board is $0.5352.  The ADS dividend
will be paid on 21 January 2003 to ADS holders of record on 6 December.

REVIEW OF OPERATIONS

MERGER UPDATE

At the  completion  of the  merger on 21  October,  we had fully  integrated  the  corporate  centres  of
National Grid and Lattice.  We have also made good progress in integrating  the support  functions of the
two UK operations in the Midlands and have  announced the new location for the combined  Midlands  office
for our UK gas and  electricity  businesses.  The  operations  of  Transco's  National  Transmission  and
Trading  business  and NGC are  now  under  single  management.  We are  confident  we  will  exceed  the
annualised £100m synergy savings by March 2004 which we announced earlier this year.


UK ELECTRICITY AND GAS NETWORKS

UK Electricity

The UK electricity  transmission  business  continued to trade strongly,  achieving  operating profits of
£284m,  an  increase  of £41m from the same period last year.  The  electricity  Transmission  Owner (TO)
business  contributed  £255m and the electricity  System  Operator (SO) £29m. This operating  performance
was driven by a further reduction in controllable costs,  excellent  performance under the electricity SO
incentive scheme and the recognition of non-recurring income for excluded services.

With the  introduction  of 'Staying  Ahead',  we have reduced  controllable  costs by 19.5% in real terms
since 1 April 2001 and are confident  that we will achieve the planned 30% real  reduction over the price
control  period to March 2006. At the same time,  high  standards of both safety and  reliability  of the
network have been maintained.  Exceptional reorganisation costs were £6m before tax (£4m after tax).


---------------------------------------------------------------------------------------------------------
REVIEW OF OPERATIONS (continued)


UK Electricity (continued)

We made good  progress  over the summer on this year's  Balancing  Services  Incentive  Scheme  ("BSIS"),
including the  successful  introduction  of one-hour  gate closure on 2 July.  BSIS  contributed  £24m to
electricity  SO  operating  profit  for the half  year.  Maintaining  performance  at this level over the
remainder  of the year will be  challenging  and will depend upon  participants'  behaviour on system and
energy balancing over the winter months.

UK interconnector profits were £10m, up £3m on the same period last year.


UK Gas Distribution and Transmission

Transco's  operating  profit fell by £15m to £178m,  primarily due to the planned increase in replacement
expenditure  which  rose by £36m  over the  first  half of last  year to  £216m.  Repex is  expensed  for
accounting  purposes,  but for  regulatory  purposes,  half of the costs are  included in the  regulatory
asset base.

In the six months to  September  2002,  controllable  costs were £11m lower than in the same  period last
year.  Initial savings from the  restructuring  programme were partially  offset by the planned  increase
in pension costs of £8m  resulting  from the 2001  actuarial  review.  We are on track to outperform  our
regulatory  targets for  controllable  costs over the 5-year price control  period.  Exceptional  Transco
restructuring costs during the period were £84m before tax (£59m after tax).

Transco's  safety  and  reliability  performance  remain  high,  and we are on track to meet the Health &
Safety Executive's  year-end target for the  decommissioning of medium pressure ductile iron (MPDI) mains
in full.

Our performance  under the new gas System Operator (SO) and Mains  Replacement  incentive  mechanisms has
been encouraging.


US ELECTRICITY AND GAS NETWORKS

National  Grid USA  continued  to deliver  strong  performance  through  the first six months of the year
despite sluggish economic conditions with very few signs of early improvement.

Integration savings are being delivered ahead of schedule,  with an annualised  reduction in controllable
costs of 4% in real terms.  Through  synergy  savings and other cost cutting  measures,  the US operation
will reduce controllable costs by 20% in real terms over the 3 year period to March 2005.

Operating  profits from energy  delivery in New England  amounted to £119m,  compared  with £121m for the
same period last year,  with the  depreciation  of the US dollar  masking a 3% increase in  underlying US
dollar profits.  In New England,  distribution  delivery  volumes  increased by 1.9% over the same period
last year,  primarily due to warmer weather.  Underlying  volume growth on a weather  corrected basis was
approximately 0.5%.

Energy  delivery  in New  York  contributed  £143m  in  operating  profit,  including  £8m  from  the gas
distribution  business.  The gas  operation's  financial  performance  is  subject to  seasonality,  with
around 15% of annual  operating  profit  typically  arising during the first half of the financial  year.
New York  electricity  delivery  growth  exhibited  similar  characteristics  to New England  with a 1.7%
increase overall.  Underlying volume on a weather corrected basis remained unchanged from year to year.


REVIEW OF OPERATIONS (continued)
---------------------------------------------------------------------------------------------------------

US ELECTRICITY AND GAS NETWORKS (continued)

Operating  profit from Stranded Cost Recovery and  Generation  ("Stranded  Costs") in New England fell to
£18m from £25m, as expected.  In New York,  Stranded Costs  contributed £63m to operating  profit.  Sales
of the last two operating  nuclear plants have been completed,  and the Group no longer owns any interest
in operational nuclear generating plants.

In New England,  the nominal  pre-tax return on investment for the six months ended 30 September 2002 was
an  annualised  9.6%,  up from  9.4% for the  year  ended 31 March  2002.  This  results  in 9.1% for the
combined business at 30 September, which keeps us on track to meet our 10.5% target by March 2005.

The  development  of  Regional  Transmission  Organisations  in the US  continues  to make  progress.  We
recently  signed  an  agreement  with  three  companies  to manage  their  transmission  assets  under an
Independent  Transmission  Company  called  GridAmerica  operating  within  the  Midwest  ISO.  The three
companies'  transmission  assets span over 17,000 miles of transmission  lines,  serving an area equal in
size to the UK. This  agreement  will be considered by the Federal  Energy  Regulatory  Commission in the
coming weeks.


OTHER ELECTRICITY OPERATIONS

Transener, our electricity  transmission joint venture in Argentina,  continued to deliver good operating
performance.  The  introduction of  hyper-inflationary  accounting  resulted in a net exceptional gain of
£38m in the period, bringing the share of net liabilities back to zero.

Following  a  detailed  consultation  process,  the  Basslink  project  to  build,  own  and  operate  an
interconnector  between the  Australian  mainland and Tasmania has  received  final  approval.  The £300m
project is due to be completed in 2005.


NON REGULATED BUSINESSES

Mobile Infrastructure Services

We are making progress in growing our mobile  infrastructure  services  business in the UK and US. In the
UK,  Gridcom  and SST are now  trading  as a single  entity,  and pro forma  operating  losses  have been
significantly  reduced  from  £31m  in the  first  half of  last  year  to a loss of £8m in this  period.
Gridcom US will launch before the end of this financial year.


Telecoms

Withdrawal from our altnet  investments is nearing  completion.  We have sold our stakes in Manquehue net
and Silica Networks and with the  restructuring of our shareholding in Energis Polska,  we have no future
funding obligation.

We  continue  to pursue an exit from  Intelig in market  conditions  that make it  difficult  to effect a
sale.  We will not provide  further  finance to Intelig to fund the  operations  of the  business and our
exit will be completed within the provisions already made.




REVIEW OF OPERATIONS (continued)
---------------------------------------------------------------------------------------------------------

Telecoms (continued)

The sale process for 186k's assets is progressing  to schedule.  As previously  indicated,  we have fully
written down the former Lattice altnet assets, resulting in an exceptional charge of £166m before tax.

As Energis  went into  administration  during  the  period,  we no longer  treat it as an  associate  and
therefore do not include any losses from it in our half year results.


PENSIONS

Financial  Reporting  Standard  (FRS) 17 has not yet been  implemented,  and the  2003  accounts  will be
prepared under SSAP24,  based on actuarial  valuations of the Group's various pension schemes.  It is the
results of periodic  actuarial  valuations  that determine the level of  contribution,  these  valuations
being based on long term financial assumptions.

Under the  proposed  FRS17,  the  accounting  values of the  Group's  pension  and other  post-retirement
benefit  assets,  liabilities  and  charges  would be  subject to the  volatility  of  short-term  market
fluctuations.  Assets would be valued on the basis of market  values at each  balance  sheet date and the
present value of the liabilities  would be calculated  using a fluctuating  discount rate by reference to
estimated  yields on AA corporate bonds or equivalent.  FRS 17 would therefore  provide a highly volatile
snapshot as at a particular date.

The FRS17 deficit (net of deferred tax) in respect of pension  obligations  for the Lattice  scheme would
be £669m at 31 October  2002,  down from a net  surplus  of £261m at 31 March  2002.  The next  actuarial
valuation  is due to be carried out as at 31 March 2003.  For the UK  operations  of National  Grid,  the
net FRS17  deficit at 31 October  2002 would be £202m,  as  compared to a net deficit of £36m at 31 March
2002.  The next  actuarial  valuation  is due to be carried out as at 31 March  2004.  For both of the UK
schemes,  precedent is for pension  costs to be allowed as an  operating  expenditure  for UK  regulatory
purposes.  The US  operations  of National  Grid would have had a net FRS17 deficit in respect of pension
and other  post-retirement  benefit obligations at 31 October 2002 of £649m, compared to a net deficit of
£406m  at 31  March  2002.  In the US,  pension  and  other  post-retirement  liabilities  are  generally
recoverable through customer rates.


OUTLOOK
---------------------------------------------------------------------------------------------------------

The  businesses  continue  to perform  strongly  and are on track to meet our  expectations  for the full
year.  Our  enlarged  Group is well  positioned  to deliver  growing  earnings,  strong  cashflow and its
progressive dividend policy.

1. Basis of Preparation

The pro forma financial information is unaudited and does not comprise statutory accounts within the
meaning of section 240 of the Companies Act 1985.  The pro forma financial information has been
reviewed by the auditors and their report is set out on page 39.

It has been prepared for illustrative purposes, as if the merger had taken place on 1 April 2001, the
first day of the comparative period.  It does not purport to represent what the combined results of
operations, cash flows and balance sheet actually would have been if the merger had occurred on 1 April
2001.

The pro forma financial information comprises an aggregation of the National Grid Group and Lattice
information (see pages 17 to 29 and 30 to 38 respectively), as adjusted for the issue of shares on
merger with a nominal value of £132m and the elimination of transactions and balances between the
former groups relating to turnover and operating costs in the relevant period and the elimination of
debtors and creditors at the balance sheet date, amounting to £22m and £7m respectively (2001: £25m and
£8m).

A pro forma adjustment of £221m (2001: £221m) has been made to other reserves, representing the
difference between shares issued of £132m and the called up share capital of Lattice Group plc at the
date of the merger.

The combination of National Grid Group and Lattice meets the merger accounting criteria under UK GAAP
and the transaction has, therefore, been accounted for as a merger.

The pro forma section of this interim results announcement was approved by the Board of Directors on 25
November 2002.

2002/03 Half Year Results

Notes                                                                                                                        Page 29



1. Basis of preparation

The financial information contained in this announcement has been prepared on the basis of the
accounting policies set out in the National Grid Annual Report and Form-20F for the year ended 31 March
2002 except as noted below and does not constitute statutory accounts as defined in Section 240 of the
Companies Act 1985.  The financial information in respect of the year ended 31 March 2002 has been
derived from the statutory accounts for the year ended 31 March 2002, which have been delivered to the
Registrar of Companies.  The auditors' report on those statutory accounts was unqualified and did not
contain a statement under Section 237(2) or (3) of the Companies Act 1985.  The financial information
in respect of the six months ended 30 September 2002 is unaudited but has been reviewed by the auditors
and their report is set out on page 39.

In translating into sterling the Group's share of the net assets and results of a joint venture
operating in a hyper-inflationary economy for the six month period ended 30 September 2002, adjustments
have been made to reflect current price levels.  Such adjustments have been reflected through the Group
profit and loss account or statement of total recognised gains and losses as appropriate.  The Group's
share of the gain on net monetary liabilities has been credited to the Group profit and loss account
through 'net interest', and is shown as part of the Group's exceptional financing costs - note 3 (c).

For the year ended 31 March 2002, exceptional financing costs of £142m were reported net of a minority
interest credit amounting to £50m.   For the period ended 30 September 2002, the comparative has been
restated to present the exceptional financing costs and related minority interest on a gross basis.

The National Grid Group Section of this interim results announcement was approved by the Board of
Directors on 25 November 2002.

2. Segmental analysis

Following the merger with Lattice Group, a review of the segmental analysis has been undertaken, with a
view to determining the appropriate segmental analysis for the new merged group, National Grid
Transco.  Consequently, the segments reported for National Grid Group below have been aligned with the
segmental analysis to be adopted by National Grid Transco.

IV)      Represents transaction costs of the merger with Lattice Group plc (£32m after tax).

c)  Financing costs

The exceptional net interest costs of £55m (£55m after tax) relates to the Group's share of exchange
losses incurred on foreign currency borrowings by joint ventures amounting to £124m, partially offset
by the Group's share of a gain on net monetary liabilities of £69m.  The gain on the net monetary
liabilities relates to Citelec, a joint venture operating in Argentina, and reflects the net gain
arising on net monetary liabilities that are financing the operation in a hyper-inflationary economy.


d)  Minority interest

The exceptional minority interest charge of £12m relates to the Group's share of the minority interest
in the after taxation operating results of Citelec, and primarily reflects the minority's share of the
gain on net monetary liabilities referred to above.

For September 2001 and March 2002, there is no difference between basic and diluted earnings per
share.  In respect of the six months and year ended 30 September 2001 and 31 March 2002 respectively,

In prior periods, the reconciling items between basic and adjusted earnings per share have been shown
net of tax.  For the period ended 30 September 2002, the comparatives have been restated to show the
reconciling items gross of tax.

1. Basis of Preparation

The financial information contained in this announcement has been prepared on the basis of the
accounting policies set out in the Lattice Annual Report for the fifteen months ended 31 March 2002
except as noted below and does not constitute statutory accounts as defined in Section 240 of the
Companies Act 1985.  The financial information in respect of the year ended 31 March 2002 has been
derived from the unaudited information for that period included in the Lattice Annual Report for the
fifteen months ended 31 March 2002.  The financial information is unaudited but has been reviewed by
the auditors and their report is set out on page 39.

The Lattice Group Section of this interim results announcement was approved by the Board of Directors
on 25 November 2002.


Changes in accounting policies

FRS 19 'Deferred Tax' was implemented on a discounted basis during the period ended 31 March 2002.  As
a result of the merger of National Grid and Lattice, accounting policies of the two groups are being
aligned.  Consequently deferred tax is now being accounted for on an undiscounted basis.

This change in accounting policy results in a significant reduction in distributable reserves in
Transco plc. It does not impact the distributable reserves of Transco's holding company, Transco
Holdings plc.  Therefore, to mitigate the impact on the Group of the reduction in Transco plc's
distributable reserves, in October 2002 Ofgem consented to Transco making loans to Transco Holdings.
Transco Holdings is now subject to a number of licence conditions as if it were Transco.  These include
restrictions on loans to affiliates and related parties and a restriction on its activities to those
permitted to be carried out by Transco and to acting as Transco's holding company.

Again, as a result of this alignment of accounting policies, the net interest credit included within
the pensions charge is now reported within net interest.  Previously this was reported in operating
costs.

The impact of the changes in accounting policies is set out below:

                                                                                                                              Year ended

2. Segmental analysis

Following the merger with National Grid, a review of the segmental analysis has been undertaken, with a
view to determining the appropriate segmental analysis for the new merged group, National Grid
Transco.  Consequently, the segments reported for Lattice Group below have been aligned with the
segmental analysis to be adopted by National Grid Transco.

Independent Review Report                                                                                                    Page 39



Independent review report to National Grid Transco plc

Introduction

We have been instructed by the company to review the financial information which comprises the group
profit and loss accounts, group statements of total recognised gains and losses, group cash flow
statements for the six months ended 30 September 2002, balance sheet information as at 30 September
2002, comparative figures and associated notes of Lattice Group plc and National Grid Group plc. We
have read the other information contained in the interim report and considered whether it contains any
apparent misstatements or material inconsistencies with the financial information.


Directors' responsibilities

The interim report, including the financial information contained therein, is the responsibility of,
and has been approved by the directors of National Grid Transco plc. The directors are responsible for
preparing the interim report in accordance with the Listing Rules of the Financial Services Authority
which require that the accounting policies and presentation applied to the interim figures should be
consistent with those applied in preparing the preceding annual accounts except where any changes, and
the reasons for them, are disclosed.


Review work performed

We conducted our review in accordance with guidance contained in Bulletin 1999/4 issued by the Auditing
Practices Board for use in the United Kingdom. A review consists principally of making enquiries of
management and applying analytical procedures to the financial information and underlying financial
data and, based thereon, assessing whether the accounting policies and presentation have been
consistently applied unless otherwise disclosed. A review excludes audit procedures such as tests of
controls and verification of assets, liabilities and transactions. It is substantially less in scope
than an audit performed in accordance with United Kingdom Auditing Standards and therefore provides a
lower level of assurance than an audit. Accordingly we do not express an audit opinion on the financial
information.


Review conclusion

On the basis of our review we are not aware of any material modifications that should be made to the
financial information as presented for the six months ended 30 September 2002.

In addition, we have reviewed, without performing an audit, the pro forma financial information which
comprises the pro forma group profit and loss account, pro forma group statement of total recognised
gains and losses, pro forma group cash flow statement for the six months ended 30 September 2002, pro
forma summary group balance sheet information as at 30 September 2002, comparative figures and
associated notes.  This pro forma financial information has been prepared, for illustrative purposes
only, as if the merger of Lattice Group plc and National Grid Group plc had taken place on 1 April
2001. The pro forma financial information is solely the responsibility of, and has been approved by,
the Directors.  On the basis of our review, we are not aware of any material modifications that should
be made to the pro forma financial information compiled on the basis set out in the notes to the
interim report.
