Our 1.5Gb broadband trial will achieve the fastest cable speeds in the world and, by pushing the frontiers of technology, it will help us to understand the kinds of services our customers may need in the future and the exciting possibilities of an increasingly converged world.”

SUMMARY FINANCIAL RESULTS

CONSUMER OPERATIONS STATISTICS

OVERVIEW

Delivering strong financial performance

We have started 2011 with improved revenue right across the business, resulting in total revenue growth for the first quarter of 5.7% to £982m. Strong cost control was maintained as SG&A fell by 3.9%. This resulted in 7.6% growth in OCF to £376m. Operating income increased 58.9% to £111m.

Free Cash Flow generation was particularly strong, more than doubling to £100m. Net cash provided by operating activities increased 34.3% to £272m.

Driving cable growth and creating convergence opportunities

The first quarter was the seventh successive quarter of both cable customer growth and year-on-year improved cable ARPU, which together drove cable revenue up 4.1%. ARPU increased 2.6% to a record for this period of the year and we added 20,200 net cable customers. The number of customers subscribing to our services has increased by 1.2% compared to a year ago.

We continue to investigate innovative and cost effective means to meet the demand for ultrafast broadband and next generation services beyond our unique cable network in ways which could expand our potential market for new customers.

During the quarter, we expanded our infrastructure to pass approximately 16,000 more homes. We have also successfully completed a comprehensive Metro Wi-Fi trial in Ashford, Kent. This public trial has proven our capabilities in exploiting our growing cable network for the provision of internet connectivity out of the home.

Leading the superfast broadband revolution

The demand for improved connectivity continues to grow, as demonstrated by the increasing proportion of new customers signing up for our faster speeds. Importantly, our typical speeds are the closest to the advertised speeds as compared to any of our competitors. We saw 39% of new subscribers in the quarter ordering speeds of 20Mb or higher, compared to 15% a year ago.

Over 860,000 customers now subscribe to tiers of 20Mb or above, which together represent 21% of our cable broadband base. In February, we unveiled a new 30Mb “XL” tier in place of the existing 20Mb tier for new customers. This will create further differentiation from our DSL competitors which struggle to deliver more than half the headline speeds they advertise.

We now have over 150,000 customers on our 50Mb tier, more than twice as many as a year ago and a 33% increase since the year-end. We are also in the process of rolling out the country’s fastest broadband service, 100Mb, which is now available to 2 million of our cable homes and on track to be available right across our network by mid 2012.

We will shortly begin a trial to test the real world application of speeds of up to 1.5Gb. This will be the fastest cable broadband connection in the world ever tested and will demonstrate the long-term potential of our superior network.

Leading in next generation digital entertainment

Our existing TV service stands apart from other services with, advantages such as access to an unparalleled library of on demand programming. Over 2.4m families, representing 64% or our TV base, are now regularly enjoying our on demand TV service. Average monthly views in Q1 were 83m, an increase of 23% from the same period in 2010.

Virgin Media’s 3D on demand TV service goes from strength to strength with a growing line-up of movies courtesy of Paramount Pictures and Disney such as ‘Jackass 3D’ and ‘TRON: Legacy’. We continue to work with content creators to source the best programming.

4

We grew our TV base by 10,100 customers in the quarter to a total of 3.8m. Of these customers, over 1.5m or 41% are able to experience HD after we added a further 66,400 HD customers in the quarter.

At the end of last year, we launched our leading entertainment service powered by TiVo, with its game-changing interface that brings together the best of TV, on demand and the web. In these early stages, demand continues to grow and, having already added thousands of customers, we are in the process of connecting the 65,000 who have pre-registered.  The service is now available for all new and existing customers to order.

Exploiting Mobile growth opportunity

Mobile revenues were up 3.8% in the quarter, as we continued to focus on growing our contract subscriber base, which increased by 23% from the end of March last year to a total of 1.3m. Mobile ARPU for the quarter increased by 7.3%, as a result of the improved proportion of higher ARPU contract customers.

One of our key strategic aims is to cross-sell more mobile services into our cable customer base as we believe this favourably impacts churn and life-time value. As at the quarter-end, we had approximately 556,000 cable households with one or more of our mobile contracts, which is up 17% on a year ago. These households had approximately 759,000 contract mobiles, up 19% and representing 60% of all contract subscribers. We also estimate we have a further 176,000 cable households with at least one of our prepay phones. Collectively, this represents 15% of our cable base that take at least one mobile service from us, leaving a significant growth opportunity to cross-sell to the remaining 85%.

We have just launched a new telephony proposition designed to further drive mobile penetration into our cable base. This rewards home phone customers who sign-up for our higher tiers of service with discounts off their mobile monthly bill.

Quad-play penetration, where a household takes all three cable products and a mobile phone service, increased to around 12.0%, compared to 11.0% a year ago.

Growing Business Data

Our Business division is pursuing its strategy to increase market share by focusing on growth in business data and leveraging our unique asset — a fibre optic network that passes close to 85% of all UK businesses. Revenues increased 13.7% for the quarter as result of growth in data revenues in both retail and wholesale markets. Business data remains a key growth opportunity for us in 2011.

During the quarter, we won a contract worth up to £20m over 10 years to provide complete voice and data services to the London Borough of Lambeth. This includes connectivity to around 200 sites, a converged, fixed and mobile voice provision, network management and secure internet bandwidth.

We also secured a five year contract with Newsquest, one of the UK’s premier media organizations to supply a network to its UK offices, and a £1.8m contract with Yorkshire Water.

Virgin Media Business was awarded the UK’s first interim Public Sector Network (PSN) security accreditation. This national milestone has come as a result of a successful security audit in accordance with new security standards. This is a significant achievement, and one that sets us apart from our competitors. As security is increasingly on the agenda for UK organizations, it’s vital that they can select a network provider that has the credentials to provide a secure end-to-end process.

We also announced a new data centre proposition that will see us extend our network into selected data centres to deliver carrier grade performance. This gives data centres the power to connect customers to a range of services at speeds up to 10Gb with true network resilience.  Each interconnect can connect up to 8,000 users and will drive significant customer cost savings through reduced space and power consumption.

Capital Return Programme Update

In July 2010, we announced a £375m share buyback programme and a target leverage ratio of approximately 3.0x Net Debt(4) to OCF(5) over the next two to three years. So far, we have repurchased

5

approximately 18.8m shares at a cost of £282m, including 7.2m in the first quarter. We retain the authority for a further £93m of buybacks until August 2011.

The continuing efforts to provide us with the most flexible capital structure possible and our success in growing the business has meant our Net Debt to OCF has improved in the last twelve months from 4.1x to 3.7x.

During the quarter, all three major credit rating agencies upgraded the ratings on our Senior Secured Debt to “Investment Grade”. This is the first time such a rating has been achieved in the UK cable industry. Following this, we issued approximately £957m equivalent aggregate principal amount of senior secured notes due 2021 in $500m and £650m tranches bearing interest at a rate of 5.25% and 5.5% respectively. £900m of the net proceeds were used to repay a portion of our existing senior credit facility. As a result we have no debt repayments due before 2015.

We intend to retire our $550m 9.125% 2016 notes by the first call date of August 15, 2011 using cash on our balance sheet, further reducing both total debt and future interest expense.

RESULTS FOR THE THREE MONTHS ENDED MARCH 31, 2011

TOTAL REVENUE

Total revenue in the first quarter was up 5.7% to £982.3m due to growth in cable, mobile, business and non-cable.

CONSUMER SEGMENT

Cable

Cable revenue in the first quarter was up 4.1% at £666.0m reflecting 2.6% growth in cable ARPU to £46.16 and 1.2% growth in the cable customer base.

Gross cable customer additions in the first quarter were relatively flat at 191,800. Average monthly churn increased from 1.1% to 1.2%. The overall cable customer base increased to 4.82m, with net additions of 20,200 for the quarter.

Mobile

Mobile revenue in the quarter was £136.9m, up 3.8%, reflecting ARPU growth driven by the increased number of contract customers.

Contract net additions for the quarter were 52,600 and at the quarter-end we had 1,263,400 contract subscribers representing 42% of total mobile products and growth of 23% in contract subscribers in the last year.

The number of prepay net disconnections in the quarter was 120,300, down 38.7%. The loss of prepay subscribers reflects the competitive market and our strategy of focusing on signing up contract customers who have lower churn and higher ARPU characteristics and therefore higher overall lifetime value.

Non-cable

Non-cable revenue in the quarter was up 15.3% at £20.3m mainly due to the continued growth in telephony line rental revenue.

BUSINESS SEGMENT

Business revenue in the quarter was £159.1m, up 13.7%, mainly due to growth in data revenues in both retail and wholesale markets. Retail data revenue was up 18.9% to £65.4m, reflecting our successful strategy of focusing on higher margin data revenue and increasing demand for our data products. Wholesale data revenue was up 34.2% at £42.0m mainly due to new customer contracts wins and

6

increased revenues from an existing customer. Retail voice revenue was down 6.2% to £38.9m as a result of declining telephony usage and pricing. Wholesale voice revenue was down 39.0% at £3.6m. Local Area Network (“LAN”) Solutions revenue was up 48.4% at £9.2m.

OPERATING COSTS AND SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (SG&A)

Operating costs (exclusive of depreciation and amortization) were £411.1m in the quarter, up 9.1%, mainly as a result of increased premium and HD programming costs and higher mobile handset expense. SG&A fell 3.9% to £195.1m for the quarter, mainly due to lower facilities, marketing and other costs.

OPERATING INCOME BEFORE DEPRECIATION, AMORTIZATION, GOODWILL AND INTANGIBLE ASSET IMPAIRMENTS AND RESTRUCTURING AND OTHER CHARGES (OCF)

OCF increased to £376.1m in the quarter, up 7.6% mainly due to the growth in revenue and reduction in SG&A, partially offset by increased operating costs.

OPERATING INCOME

Operating income in the quarter was £110.6m, up 58.9% mainly due to increased OCF and reduced depreciation.

Depreciation expense was down 5.6% at £228.8m primarily as a result of certain fixed assets becoming fully depreciated, partially offset by increases in depreciation in respect of new fixed assets. Amortization expense was £34.1m, down 8.1% mainly due to the cessation of amortization of certain intangible assets that became fully amortized in 2010.

UKTV JOINT VENTURE

Virgin Media owns 50% of the companies that comprise UKTV, a group of joint ventures formed with BBC Worldwide. UKTV produces a portfolio of television channels based on the BBC’s programme library and other acquired programming which are carried on Virgin Media’s cable platform and also on satellite. Some channels are also available on Freeview.

Virgin Media accounts for its interest in UKTV under the equity method and recognized a share of UKTV’s net income of £8.2m in the quarter. UKTV’s financial results are not consolidated in Virgin Media’s revenue, operating income or OCF. Virgin Media’s investment in UKTV is carried on the balance sheet at March 31, 2011 at £351m, which includes loans to fund its operations totaling £110m.

In the quarter, Virgin Media received £6.4m from UKTV in the form of net loan capital repayments together with cash payments totaling £11.1m, which consisted of dividends, interest payments and payments for consortium tax relief.

NET INCOME FROM CONTINUING OPERATIONS

Net income from continuing operations for the quarter was £4.5m compared to a loss of £163.3m in the first quarter of 2010. The improvement was mainly due to increased operating income, gains on derivative instruments and foreign currency gains, which arose due to sterling strengthening versus the US dollar during the quarter.

CAPITAL EXPENDITURE

Fixed asset additions (accrual basis)(6) in the quarter were up 2.7% at £177.3m. The total purchase of fixed assets and intangible assets was down 10.0% at £163.3m mainly due to the timing of payments to fixed asset suppliers and an increase in fixed assets acquired under finance leases.

FREE CASH FLOW

Free Cash Flow for the quarter was up 117.6% to £99.9m mainly due to higher OCF, lower total purchase of fixed assets and intangible assets and lower net interest expense. Net cash provided by operating activities was up 34.3% at £271.6m.

7

DEBT

As of March 31, 2011, long term debt, net of £421m current portion, was £5,596m. Total debt consisted of £775m outstanding under our Senior Credit Facility, £2,034m of Senior Notes, £2,428m of Senior Secured Notes, £525m of Convertible Senior Notes and £254m of capital leases and other indebtedness. Cash and cash equivalents were £483m. Net debt was £5,534m.

The increase in the current portion of long term debt reflects our decision to retire our $550m 9.125% 2016 notes, as referenced above.

Interest expense in the first quarter was £114.6m, down 7.1% due to a lower level of debt paying interest at fixed rates.
