BT Group Half Year Results and Interim Report


Chairman's Statement

The half year results show that we have delivered another good set of financial
results and made further progress in transforming the business.

I am pleased to report that we will be paying an interim dividend of 4.3 pence,
up 10 per cent on last year, showing our commitment to improving shareholder
returns and confidence about the future.

                                          Sir Christopher Bland, 9 November 2005
________________________________________________________________________________

Review

The  results  show  that the  transformation  of BT is  right on track  with the
delivery of another  successful  half year.  Group revenue  increased 5 per cent
with continued strong growth in new wave revenue,  up 43 per cent, driven by our
networked  IT services and  broadband  businesses.  Total  networked IT services
contract  wins amounted to GBP8.2  billion over the last 12 months.  We now have
more than 6.2 million  wholesale  broadband  connections,  an increase of 89 per
cent  compared  to last year.  This strong new wave growth was offset by a 6 per
cent decline in revenue from our traditional businesses.

Group profit before taxation, specific items and leaver costs increased by 3 per
cent,  with the reduction in net finance costs and  improvements  in operational
efficiency  offset by the costs of supporting the growth in new wave activities.
Reported profit before taxation, including specific items and leaver costs was 1
per cent  higher  than last  year.  Specific  items for the half year were GBP82
million  (see Note 2) and  principally  comprise a  provision  of GBP70  million
relating to the costs of creating  Openreach,  a new line of  business.  This is
part of the final settlement  reached with Ofcom following the conclusion of the
Telecommunications   Strategic  Review.  Their  acceptance  of  legally  binding
undertakings offered by BT provides a foundation for certainty and clarity which
will  deliver   further   benefits  to  retail  and   wholesale   customers  and
shareholders.

Earnings per share  before  specific  items and leaver costs were 9.8 pence,  an
increase of 5 per cent.  Reported earnings per share,  including  specific items
and leaver costs were 2 per cent higher at 8.8 pence.

Net debt has fallen to GBP8.1  billion,  3 per cent  below last year.  Free cash
flow generated in the first half amounted to GBP377 million.

An interim  dividend of 4.3 pence per share will be paid on 13 February  2006 to
shareholders on the register on 30 December 2005.

The strategy is working well and we continue to deliver our key strategic goals.
Our  traditional  business  continues to operate in what  remains a  challenging
environment.  Our new wave  businesses  show  strong  growth  both in the UK and
internationally.  We expect to continue to see the benefits from our  investment
in new wave activities and cost transformation plans.

Notes
     
1    With effect from 1 April 2005, the group moved to reporting its financial 
     results in accordance with International Financial Reporting Standards
     (IFRS) adopted for use in the European Union. On 28 July 2005, the group 
     issued its first quarter results (available at 
     www.btplc.com/Sharesandperformance) which also contained information on the
     impact of IFRS on comparative periods in advance of the publication of the 
     group's first annual results under IFRS. Details of the group's principal 
     accounting policies under IFRS were also included. The financial 
     information set out in this interim statement has been prepared in 
     accordance with those accounting policies and the directors intend to apply
     those policies in the preparation of the consolidated financial statements 
     for the year ended 31 March 2006. Additional disclosure on the impact of 
     IFRS at 30 September 2004 is also included in the full interim results
     statement. As permitted, the group has chosen not to adopt IAS 34 "Interim
     Financial Statements" and therefore the interim financial results are not 
     in full compliance with IFRS.
     
2    The results as shown in the summarised income statement are reported
     inclusive of specific items. Specific items comprise material one off or 
     unusual items, which are separately identified and disclosed. This is 
     consistent with the way that financial performance is measured by 
     management and provides a meaningful analysis of the trading results of the
     group. Specific items recognised for the six months ended 30 September 2005
     were GBP82 million (2004: net profit of GBP8 million) comprising a 
     provision of GBP70 million for the costs required to create a new line of 
     business, Openreach, and property rationalisation costs of GBP12 million.

     This advertisement is a summary of the interim results of BT Group plc 
     ("the group") for the six months ended 30 September 2005. The full interim 
     results statement, including the group's results for the three months ended
     30 September 2005, is available on the internet at 
     www.btplc.com/Sharesandperformance. If you have any queries as a

Independent Review Report to BT Group plc

Introduction

We have been instructed by the group to review the financial information for the
six months ended 30 September 2005, which comprises the summarised group income
statement, group statement of recognised income and expense, group cash flow
statement and group balance sheet at 30 September 2005. 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. The directors are
responsible for preparing the interim report in accordance with the Listing
Rules of the Financial Services Authority.

As disclosed in Note 1, the next annual financial statements of the group will
be prepared in accordance with accounting standards adopted for use in the
European Union. This interim report has been prepared in accordance with the
basis set out in Note 1. As permitted the group has chosen not to adopt IAS 34
"Interim Financial Statements" and therefore the interim financial information
is not in full compliance with International Financial Reporting Standards
(IFRS).

As explained in Note 1, the accounting policies are consistent with those that
the directors intend to use in the next annual financial statements. There is,
however, a possibility that the directors may determine that some changes are
necessary when preparing the full annual financial statements for the first time
in accordance with accounting standards adopted for use in the European Union.
The IFRS and the International Financial Reporting Interpretations Committee
(IFRIC) interpretations that will be applicable and adopted for use in the
European Union at 31 March 2006 are not known with certainty at the time of
preparing this interim financial information.

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 group 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. 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 and therefore provides a lower level
of assurance. Accordingly we do not express an audit opinion on the financial
information. This report, including the conclusion, has been prepared for and
only for the group for the purpose of the Listing Rules of the Financial
Services Authority and for no other purpose. We do not, in producing this
report, accept or assume responsibility for any other purpose or to any other
person to whom this report is shown or into whose hands it may come save where
expressly agreed by our prior consent in writing.

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 2005.
