                COLT TELECOM GROUP PLC ANNOUNCES RESULTS FOR THE

                    QUARTER AND YEAR ENDED 31 DECEMBER 2004

              Solid fourth quarter performance; business refocused


COLT Telecom Group plc (COLT), a leading pan-European provider of business
communications solutions and services said today that in the fourth quarter it
had delivered a solid financial performance, had refocused the business and had
begun the implementation of its new strategic plan.


HIGHLIGHTS OF THE QUARTER


  - Turnover was GBP308.0 million compared with GBP303.7 million in the third
    quarter, an increase of 1.4%. Turnover decreased by 1.4% on a constant
    currency basis (0.5% excluding reductions in fixed to mobile prices)
  - Gross margin before depreciation was 34.2% compared with 31.6% in the
    third quarter reflecting improved mix
  - EBITDA (1) was GBP35.6 million compared with GBP33.4 million in the third
    quarter
  - Net capital expenditure was GBP35.3 million
  - Strong year end financial position with cash and liquid resources of
    GBP452.7 million
  - Early redemption of GBP322.0 million of bonds with a further GBP80.9 million
    in January 2005 resulting in net interest saving of GBP31.1 million over the
    next three years
  - New strategic plan defined and implementation commenced
  - Further successful expansion of presence in India - 5% of workforce now
    in India

OVERVIEW OF THE YEAR

Turnover  increased by 7% to GBP1,214.0 million on a constant currency basis and
excluding  Fitec which was disposed of in December  2003.  Gross  margin  before
depreciation  declined slightly from 34.2% to 33.0%. EBITDA was GBP153.7 million
compared  with GBP163.4  million and pre-tax  losses  before  exceptional  items
reduced by 15% to GBP114.6 million. Net capital expenditure was GBP124.7 million
compared with GBP141.0 million.  There was a free cash outflow of GBP9.5 million
in 2004, reduced from an outflow of GBP30.4 million in 2003. COLT Chairman Barry
Bateman said:

"2004 was a tough year for the telecommunications industry and COLT.
Nevertheless, turnover was up, losses were down and cash flow improved. We have
entered 2005 in a stronger position having put in place the management team and
strategic initiatives to move COLT forward to long term profitability.

"We do not anticipate any significant improvement in market conditions during
2005 but by building on the recent momentum established by the new management
team we expect further progress and remain on track to be free cash flow
positive on a sustainable basis during the year."

exchange and exceptional items

Commenting on progress made during the quarter Jean-Yves Charlier, Chief
Executive Officer, said:

"We have  delivered a solid fourth  quarter  performance.  Whilst revenue growth
between the third and fourth  quarters was  adversely  affected by reductions in
fixed to mobile  prices,  revenue mix improved as a result of the action we have
taken to reduce the proportion of lower margin carrier  revenues.  This resulted
in  pre-depreciation  gross margin improving from 31.6% to 34.2%.  Whilst EBITDA
rose  from  GBP33.4  million  in the  third  quarter  to  GBP35.6  million,  the
improvement  was tempered by an increase in SG&A costs due mainly to the further
investment  in our  platform  in  India,  increased  personnel  costs  and costs
associated with Sarbanes Oxley compliance.

"The business was refocused during the quarter as we put in place an enhanced
set of strategic initiatives designed to re-establish COLT as an innovator and
as one of the top three players in each of the metropolitan markets in which it
operates across Europe. This is a three year programme and our challenge for
2005 is to begin to deliver against those initiatives by accelerating revenue
growth, improving mix, improving productivity and being free cash flow positive
on a sustainable basis.

"It is still early days but we have made a good start. We put in place an
organisation designed to deliver our strategic objectives including a further
significant move of activity to India. We launched three new Ethernet services
for the corporate market, including the first Switched Ethernet VPN service in
Europe, and our Secure IT service designed to meet the specific needs of the SME
market. Planning is well advanced for the launch of our Voice IP service early
in the second quarter."

FINANCIAL REVIEW

Unless otherwise stated all comparisons are between the quarter and year ended
31 December 2004 and 31 December 2003. Unless otherwise stated all numbers are
quoted before exceptional items and at actual exchange rates.

Turnover

Turnover for the quarter was GBP308.0 million (2003: GBP306.3 million). This was
an  increase  of 2% on a constant  currency  basis and  excluding  the  turnover
contributed by Fitec (which was disposed of in December 2003).  Turnover for the
year was GBP1,214.0 million (2003:  GBP1,166.3 million). This was an increase of
7% on a constant currency basis and excluding the turnover contributed by Fitec.
The increase in turnover was driven by demand for COLT's  services from existing
and new customers and new service introductions.

Corporate

Turnover from  corporate  customers for the quarter  decreased by 1% to GBP179.9
million  (2003:  GBP181.4  million) and for the year increased by 1% to GBP698.3
million (2003: GBP692.7 million).  Turnover from corporate customers represented
58% of total  turnover  in the quarter  and year  (2003:  59% in both  periods).
Switched  turnover  for the quarter  decreased by 3% to GBP85.2  million  (2003:
GBP88.2 million) and was marginally down for the year at GBP336.1 million (2003:
GBP337.0  million).  Non-switched  turnover  for the quarter  increased by 1% to
GBP94.2  million  (2003:  GBP93.2  million) and for the year  increased by 1% to
GBP359.3 million (2003: GBP354.8 million).

Wholesale

Turnover from  wholesale  customers for the quarter  increased by 3% to GBP128.1
million  (2003:  GBP124.9  million) and for the year increased by 9% to GBP515.7
million (2003: GBP473.6 million).  Turnover from wholesale customers represented
42% of total  turnover  in the quarter  and year  (2003:  41% in both  periods).
Switched  turnover for the quarter  increased by 2% to GBP102.1  million  (2003:
GBP99.8  million) and for the year  increased by 12% to GBP411.0  million (2003:
GBP365.7  million).  Included in switched turnover from wholesale  customers was
turnover from other telecommunications  carriers of GBP63.9 million and GBP264.1
million  for the  quarter  and year  respectively  (2003:  GBP63.7  million  and
GBP238.9  million).  Non-switched  turnover  for the quarter  increased by 3% to
GBP26.0  million  (2003:  GBP25.1  million) and for the year  decreased by 3% to
GBP104.5 million (2003: GBP107.6 million).

Cost of Sales

Cost of  sales  for the  quarter  increased  by 3% to  GBP255.6  million  (2003:
GBP248.1 million) and for the year increased by 4% to GBP1,005.7  million (2003:
GBP971.4 million).

Interconnection  and network  costs for the quarter  increased by 3% to GBP202.8
million  (2003:  GBP197.7  million) and for the year increased by 6% to GBP813.7
million (2003: GBP766.9 million). The increase for the year was driven mainly by
the increase in switched minutes.

Network  depreciation for the quarter  increased by 5% to GBP52.8 million (2003:
GBP50.4  million) and for the year  decreased by 6% to GBP192.0  million  (2003:
GBP204.4 million). The decrease for the year reflected the effect of some assets
being fully depreciated,  partially offset by further investment in fixed assets
to support the growth in demand for services and new service developments.

Operating Expenses

Operating  expenses for the quarter  increased by 12% to GBP78.0  million (2003:
GBP69.6  million) and for the year  increased by 1% to GBP277.2  million  (2003:
GBP274.5 million).

Selling, general and administrative (SG&A) expenses for the quarter increased by
15% to GBP69.6 million (2003:  GBP60.3 million) and for the year increased by 5%
to GBP246.6 million (2003:  GBP235.9 million).  SG&A expenses as a proportion of
turnover for the quarter and year was 23% and 20% (2003:  20% in both  periods).
The increases in SG&A expenses  reflected the initial costs  associated with the
establishment of COLT's presence in India,  increased  personnel costs and costs
associated with Sarbanes-Oxley compliance.

Other  depreciation and amortisation for the quarter  decreased by 10% to GBP8.4
million  (2003:  GBP9.3  million)  and for the year  decreased by 21% to GBP30.5
million (2003:  GBP38.5  million).  The reductions  reflected the effect of some
assets being fully  depreciated,  partially  offset by increased  investment  in
customer service and other support systems.

Interest Receivable, Interest Payable and Similar Charges

Interest  receivable  for the quarter  decreased by 33% to GBP4.4 million (2003:
GBP6.5  million)  and for the year  decreased by 21% to GBP21.0  million  (2003:
GBP26.7 million).  The decreases were as a result of reduced average balances of
cash and investments in liquid resources following the redemption of some of the
Company's outstanding notes during 2003 and 2004.

Interest  payable and similar  charges  for the quarter  ended 31 December  2004
decreased by 27% to GBP15.3  million  (2003:  GBP21.0  million) and for the year
decreased by 24% to GBP66.8  million (2003:  GBP88.3  million).  These decreases
were due primarily to the reduction in debt levels  following the  redemption of
some of the Company's outstanding notes during 2003 and 2004.

Interest  payable and similar  charges for the quarter  included  GBP5.0 million
(2003:  GBP8.6 million) of interest and accretion on convertible debt and GBP8.9
million  (2003:  GBP12.3  million) of interest and accretion on  non-convertible
debt. Interest payable and similar charges for the year included GBP30.2 million
(2003:  GBP34.4  million) of interest  and  accretion  on  convertible  debt and
GBP35.0   million  (2003:   GBP51.7   million)  of  interest  and  accretion  on
non-convertible  debt.  Interest  payable  and  similar  charges for the quarter
comprised   GBP11.5  million  and  GBP3.8  million  of  interest  and  accretion
respectively.

Gain on Redemption of Debt

Gains  arising on the early  redemption  of GBP335.3  million of debt during the
year were GBP0.2 million (2003: GBP7.6 million).

Exchange Gains

For the quarter  there were exchange  losses of GBP0.2  million  (2003:  gain of
GBP2.3 million).  For the year there were no net exchange gains or losses (2003:
gain of GBP6.4 million). The exchange gains in the prior year were due primarily
to movements in the British pound  relative to the U.S.  dollar on cash and debt
balances denominated in U.S. dollars.

Tax on Loss on Ordinary Activities

COLT had no taxable profits in the years ended 31 December 2003 and 2004.

                         Notes to Financial Statements

1. Basis of presentation and principal accounting policies

COLT Telecom Group plc ("COLT" or the "Company"), together with its
subsidiaries, is referred to as the Group. Consolidated financial statements
have been presented for the Group for the three and twelve months ended 31
December 2003 and 2004.

The financial statements for the twelve months ended 31 December 2003 and 2004
and at 31 December 2003 and 2004 have been extracted from the Group's audited
financial statements for those periods and do not constitute the Group's
statutory accounts for those periods. The auditors have made a report on the
Group's financial statements for the years ended 31 December 2003 and 2004 under
Section 235 of the Companies Act 1985 which does not contain a statement under
sections 237 (2) or (3) of the Companies Act and is unqualified. The statutory
accounts for the twelve months ended 31 December 2003 have been filed and the
statutory accounts for the twelve months ended 31 December 2004 will be filed
with the Registrar of Companies.

Accounting policies and presentation applied are consistent with those applied
in preparing the Group's financial statements for the year ended 31 December
2003 except for the adoption of UITF 38 "Accounting for ESOP trusts". Applying
the UITF has resulted in the cost of own shares, previously reported as a fixed
asset investment, being shown as a deduction from shareholders' funds. A prior
year adjustment has been made to reflect this change. The aggregate impact of
this adjustment on the previously reported Balance Sheet as at 31 December 2002
and 2003 is to reduce Equity Shareholders' funds by GBP0.2 million. In addition,
GBP0.9 million has been included in the Statement of Total Recognised Gains and
Losses being the amount charged to the Profit and Loss Account in prior years to
write-down the carrying value of these shares. The adoption of UITF 38 has had
no impact on the Profit and Loss Account in either 2003 or 2004.

Certain British pound amounts in the financial statements have been translated
into U.S. dollars at 31 December 2004 and for the periods then ended at the rate
of $1.916 to the British pound, which was the noon buying rate in the City of
New York for cable transfers in British pounds as certified for customs purposes
by the Federal Reserve Bank on such date. Such translations should not be
construed as representations that the British pound amounts have been or could
be converted into U.S. dollars at that or any other rate.

(i) The Group acquired ImagiNet in July 1998 and Fitec in July 2001. The
consideration for both of these purchases included deferred shares and payments.
The final elements of the consideration were paid in July 2003.

Under U.K. GAAP, the deferred shares and payments were included in the purchase
consideration. The excess purchase consideration over the fair value of assets
and liabilities acquired was attributed to goodwill and is being amortised over
its estimated economic life.

Under U.S. GAAP, these deferred shares and payments were excluded from the
purchase consideration and recognised as compensation expense in the profit and
loss account over the period in which the payments vested. Total compensation
charge for the three and twelve months ended 31 December 2003 was GBPnil million
and GBP0.3 million respectively. Because no payments were outstanding in the
twelve months to 31 December 2004, the total compensation charge for the period
was GBPnil.

(ii) The Group operates an Inland Revenue approved Savings-Related Share Option
Scheme ("SAYE Scheme"). Under this scheme, options may be granted at a discount
of up to 20%. Under U.K. GAAP no charge is taken in relation to the discount.
Under U.S. GAAP, the difference between the market value of the shares on the
date of grant and the price paid for the shares is charged as a compensation
cost to the profit and loss account over the period over which the shares vest.

                         Notes to Financial Statements

Also under U.S. GAAP, an employer's offer to enter into a new SAYE contract at a
lower price causes variable accounting for all existing awards subject to the
offer. Variable accounting commences for all existing awards when the offer is
made, and for those awards that are retained by employees because the offer is
declined, variable accounting continues until the award is exercised, forfeited
or expires unexercised. New awards are accounted for as variable to the extent
that the previous, higher priced options are cancelled.

The total expected compensation cost is recorded within equity shareholders'
funds as unearned compensation and additional paid in share capital, with
unearned compensation being charged to the profit and loss account over the
vesting period. The total compensation cost for the three and twelve months
ended 31 December 2003 was a charge of GBP0.2 million and GBP0.7 million
respectively and for the three and twelve months ended 31 December 2004 was a
credit of GBPnil million and GBP0.3 million respectively.

(iii) Under U.S. GAAP, goodwill with an indefinite useful life is not amortised
but is tested for impairment annually. Under U.K. GAAP goodwill is amortised on
a straight line basis over its useful economic life.

The Group had unamortised  goodwill of GBP8.5 million at 31 December 2004, which
is no longer  amortised  under U.S.  GAAP but which is assessed  for  impairment
annually.  Amortisation expense related to goodwill, under U.K. GAAP, was GBP0.5
million  and GBP2.1  million for the three and twelve  months  ended 31 December
2003 and for the three and  twelve  months  ended 31  December  2004 was  GBP0.5
million and GBP2.0 million respectively.

(iv) Under U.K. GAAP, the Group does not capitalise interest. Under U.S. GAAP,
the estimated amount of interest incurred on capital projects is included in
fixed assets and depreciated over the lives of the related assets.

(v) In 2000 and 2001 the Group concluded a number of infrastructure sales in the
form of 20-year indefeasible rights-of-use ("IRU") with characteristics which
qualify the transactions as outright sales under U.K. GAAP. Under U.S. GAAP,
these sales are treated as 20-year operating leases. The adjustment reflects the
recognition of profit under U.S. GAAP on the sale of IRUs concluded in prior
years.

(vi) The Group has received warrants from certain suppliers in the ordinary
course of business. Under U.K. GAAP, warrants are treated as financial assets
and recorded at the lower of cost or fair value. Hence for U.K. GAAP purposes
the warrants have been recognised at nil. Under U.S. GAAP, the warrants are
recorded at fair value with unrecognised gains and losses reflected in the
profit and loss account.

(vii) Under U.K. GAAP, customer installation revenue is recognised in the same
period as the related costs. Under U.S. GAAP, such installation revenue is
recognised over the expected customer relationship period.

Under U.S. GAAP, the Group has historically applied a policy of also deferring
attributable direct costs up to the level of associated revenue and recognising
them over the customer relationship period. The Group has now changed this
accounting policy to expensing these costs as incurred. This change has been
presented as though it took effect from 1 January 2004.

The Group has decided to change this accounting policy to reflect the way that
the business is now being monitored and run by senior management. Additionally,
the Group will be adopting IFRS from 1 January 2005. Under IFRS, only certain
attributable directs costs are allowed to be deferred and the Group has elected
that the best representation of its current business is to expense such costs.

The cumulative effect of the change on the opening retained earnings of GBP72.6
million has been recorded as a charge to the current year loss for the period
under U.S. GAAP. The effect of the change in accounting policy for the current
year is to increase the loss for the period under U.S. GAAP by GBP68.1 million
(being the net of the impact on opening retained earnings of GBP72.6 million and
the reduction in the amount of costs which would have been deferred under the
old policy in 2004 of GBP4.5 million).

                         Notes to Financial Statements

The disclosure below reflects the pro forma impact on loss for the period, under
U.S. GAAP, of the change in accounting policy assuming it had been applied
retroactively in 2003 and 2004.

(viii) During the quarter ended 30 September 2002, the Group recorded charges of
GBP443.8 million under U.S. GAAP to reflect the impairment of goodwill, network
and non-network fixed assets, resulting in a GAAP difference of GBP107.2 million
at that time. For the three and twelve months ended 31 December 2004
depreciation in the amount of GBP2.8 million and GBP11.2 million was recorded in
respect of the assets which had not been impaired for U.S. GAAP purposes.

(ix) The Group operates a number of employee share schemes on which it incurs
employer payroll taxes. Under U.K. GAAP, the cost of employer payroll taxes is
recognised over the period from the date of grant to the end of the performance
period. Under U.S. GAAP, the cost is recognised when the tax obligation arises.

c. Effects of conforming to U.S. GAAP - stock options

At 31 December 2004 the Group had certain options outstanding under its Option
Plan. As permitted by SFAS No.123, "Accounting for Stock-Based Compensation",
the Group elected not to adopt the recognition provisions of the standard and to
continue to apply the provisions of Accounting Principles Board Opinion No.25,
"Accounting for Stock Issued to Employees," in accounting for its stock options
and awards. Had compensation expense for stock options and awards been
determined in accordance with SFAS No.123, the Group's loss for the three months
ended 31 December 2004 would have been GBP41.2 million ($78.9 million).
