TELEWEST TODAY ANNOUNCED ITS INTERIM RESULTS.

Commenting on the results Charles Burdick, Group Finance Director, said:
"I am very pleased with the strong results for the first half of 1998. Total
revenues are almost 25 per cent higher than the corresponding period last year,
while earnings before interest, tax and depreciation (EBITDA) are up by more
than 230 per cent and are already above the full 1997 result.

"Our household penetration has risen to 34.5 per cent; sales of business
telephone lines and revenues per business customer are, respectively, 41 per
cent and 20 per cent higher; and we have further improved the margins of both
telephony and cable television.

"We have reduced selling, general and administrative costs as a proportion of
revenues to 41 per cent, compared to over 50 per cent in 1997. We have also
achieved a 50 per cent reduction in capital expenditure while completing our
national network and continuing to develop our local broadband systems.


"The company ended the second quarter of 1998 with (pound)1.51 billion of debt
split between (pound)0.6bn of Senior Bank debt and (pound)0.91bn of bond debt.
We are fully funded and operating comfortably within our restructured bank
facilities.

"We are currently looking at financing options with regard to the exercise of
our pre-emption rights resulting from the Comcast/NTL merger and the purchase of
Comcast's Birmingham Cable and Cable London shareholdings."


David Van Valkenburg, Chief Executive of Telewest, said:

"The second quarter of 1998 has been an exciting period for Telewest. Our
interim results show we are well placed to sustain our leading position in the
cable market.

"Cable TV and telephony penetration have reached record levels, we have launched
new services for the residential and business markets and we have earned more in
the first six months of this year than we did in the whole of 1997.
These achievements are a credit to everyone at Telewest.

"Our new Millennium packages are growing in popularity and we see evidence that
the wider choices we are offering are what customers want from their pay-TV
service. Penetration in the North East region has grown by 5.5 percentage points
since we introduced the Millennium package a year ago. This indicates the
near-term opportunity to increase penetration throughout our regions as we
re-market all our customer base with Millennium.

"Front Row has exceeded all our expectations. One in five of our customers is
regularly using the service. We have brought forward our plans to expand Front
Row from a four to eight-channel service and to accelerate the introduction of
remote-control ordering facilities in all our franchises.

"While churn in cable TV declined in the second quarter, both TV and telephony
churn are receiving our close attention. There are encouraging signs that we
have tackled the product-related causes of churn. Our efforts are now focused on
bolstering the support systems our people need to serve our customers most
effectively.

"In the business market, volumes continued to rise sharply in terms of
customers, lines per customer, and revenue per customer. In particular we have
been very successful in selling digital products to our business customers.

"The completion of our national network means we are ready to expand our range
of products and services. The network will allow us to design more sophisticated
solutions for corporate customers and be more innovative in our pricing and
packaging of voice and data services. We will also be creating a new business
unit to target the substantial opportunities in the provision of wholesale
services for other operators.

"Looking ahead, we expect to start trials of digital services later this year
and to launch services in 1999. In addition to digital broadcast and
subscription television channels, we will dedicate 40 - 50 channels to near
video on demand services, offer Internet access through the TV and give
consumers access to a wide range of interactive services.

"We will also be launching high speed Internet services in the first half of
1999. Our cable modems will connect users to the Internet at up to 100 times the
speed of a normal telephone line. We are currently exploring joint venture
possibilities with content providers and other cable operators to maximise this
opportunity.

"Finally, on 15th April 1998 we announced that the boards of Telewest and
General Cable PLC had agreed the terms of a proposed merger and that we intend
to exercise our options to acquire the interests held by Comcast UK Cable
Partners Ltd in Birmingham Cable and Cable London (subject to, inter alia, price
and availability of finance). Together these transactions will, when
implemented, create the largest UK cable operator and one better positioned to
capitalise on the excellent progress made to date."

The consolidated financial statements as set out on pages 12 and 13 which are
unaudited, have been prepared on the basis of the accounting policies set out in
the Group's 1997 Annual Report. The balance sheet, profit and loss account and
cash flow information at 31 December 1997 is derived from the statutory accounts
for 1997 which have been delivered to the Registrar of Companies. The auditors
have reported on those accounts: their report was unqualified and did not
contain a statement under section 237(2) or (3) of the Companies Act 1985.

The economic environment in which the Company operates is the United Kingdom
("UK") and hence its reporting currency is Pounds Sterling ("(pound)"). Merely
for convenience, the financial statements contain translations of certain Pounds
Sterling amounts into US Dollars at $1.666 per (pound)1.00, the Noon Buying Rate
of the Federal Reserve Bank of New York on June 30, 1998. The presentation of
the US Dollar amounts should not be construed as a representation that the
Pounds Sterling amounts could be so converted into US Dollars at the rate
indicated or at any other rate.
