OVERVIEW

Delivering strong financial performance throughout 2010

2010 was a year of improved revenue for every area of our business, leading to 5.8% growth in total revenue to £3,876m. Strong cost control was reflected in an expanded gross margin and SG&A growth of just 0.5%. This resulted in OCF(1) increasing by 12.0% to £1,510m. Operating income increased 144% to £322m.

Free Cash Flow(1) increased by 24.2% to £412m. Net cash provided by operating activities was up 16.1% to £1,038m.

(1)OCF and Free Cash Flow are non-GAAP financial measures. See Appendix F for reconciliations of non-GAAP financial measures to their nearest GAAP equivalents.

Driving cable growth

The combination of a 4.9% increase in customer spend (ARPU) and a 1.6% uplift in the number of customers drove 6.7% cable revenue growth in the fourth quarter. ARPU hit an all time high of £47.51. Cable customer net additions for the full year were 76,600, up from 17,600 for 2009. Cable net customer additions in the fourth quarter were 17,100.

Over the course of 2010 we have invested in the expansion of our unique digital cable infrastructure to reach a further 177,000 homes in addition to the 110,000 added in 2009. We continue to investigate innovative and cost effective means to meet the demand for ultrafast broadband and next generation services beyond our network for the first time.

Leading the superfast broadband revolution

Appetite for greater connectivity clearly continues to grow as we passed 4m cable broadband customers for the first time and saw a 40% year-on-year increase in the number of households paying for speeds of 20Mb or higher. The proportion of new customers subscribing to these faster speeds at sign-up was 32% in the fourth quarter - twice that at the end of 2009. Over 780,000 customers now subscribe to these higher tiers which together represent 20% of our cable broadband base.

This demand is being driven by the explosion in data consumption, caused by the burgeoning number of connected devices in the home and the increase in watching bandwidth-heavy video online. We now carry over half a terabit of data per second during busy periods. At that rate it is possible to download 62 copies of the entire Encyclopedia Britannica every second.

We now have over 118,000 customers on our 50Mb tier, nearly three times as many as a year ago and a 29% increase on the third quarter. This was the fastest widely available broadband connection in the UK until the launch of our 100Mb tier right at the end of 2010. We started the rollout of this new service, capable of delivering speeds that are almost twenty times the national average, in December and it will be enabled across the network throughout 2011 and into 2012. The equipment provided with each 100Mb connection is capable of speeds of up to 400Mb as we look to ensure the longevity of our speed advantage.

In February 2011, we unveiled a new 30Mb tier in place of the existing 20Mb tier for new customers and expect existing customers to upgrade to this faster service over time. In addition, we are making good progress on our programme to upgrade upload speeds for all of our cable broadband customers to create a consistent 10:1 download to upload ratio across every tier. The total broadband base increased by 44,100 in the quarter to 4.3m customers.

Leading in next generation digital entertainment

At the end of the 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. This is served by our unparalleled network which ensures a superb viewing experience no matter whether in Standard Definition (SD), HD or 3D. As the service utilizes dedicated spectrum and has its own internal modem — unlike any other existing or prospective internet connected TV service in the UK — the user’s viewing choice will not come at the expense of their broadband connection, so households can watch and surf online

simultaneously without interruption. This also means that customers are able to watch what they want immediately rather than waiting for time-consuming downloads.

Our existing TV service stands apart from other services that also offer hundreds of traditional SD and HD channels because of the instant access our customers have to an unparalleled library of on demand programming. During the quarter we added FIVE’s catch-up service to complete our roster of on demand players from all the UK’s terrestrial broadcasters, becoming the first and only platform to provide this.

In the four years since the formation of Virgin Media over a million more families are now regularly enjoying on demand TV, with reach increasing to 64% of our TV customers in Q4. Collectively they watched nearly 900m shows during 2010, an increase of more than 10% over the previous year. Average monthly views in Q4 were 87m, an increase of 17% from the same period in 2009.

We have also added more content to our ground-breaking 3D on demand TV service as it has become available. Customers can enjoy a variety of 3D films, such as ‘Despicable Me’ and ‘The Hole’, and 3D documentaries and animations. We continue to work with content creators to source the best programming.

We grew our TV base by 12,100 customers in the quarter to a total of 3.8m. Of these customers, 39%, or 1.48m, are able to experience HD after we added a further 91,900 HD customers in the quarter.

Exploiting Mobile growth opportunity

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 year-end, we had approximately 535,600 cable households with one or more mobile contracts, which is up 19% on a year ago. We also estimate we have a further 185,700 cable households with at least one prepay phone. Collectively, this represents 15% of our cable base that take at least one mobile service from us, meaning that there is a significant growth opportunity to cross-sell to the remaining 85%. Quad-play penetration, where a household takes all three cable products and a mobile phone service, increased to around 11.8%, compared to 10.6% a year ago. The ARPU of these quad-play customers is estimated to be over £80, significantly higher than the £47.51 average cable ARPU.

Mobile revenues were up 4.5% in the year and 6.7% for the quarter, as compared to the fourth quarter of last year, as we continued to focus on growing our contract subscriber base, which increased by 27% in the year, to a total of 1.2m. Mobile ARPU for the quarter increased by 8.3%, as a result of the improved proportion of higher ARPU contract customers.

Growing Business Data

One year ago we relaunched our Business division as Virgin Media Business with a 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 2.8% for the year with the impact of the change increasingly seen over time as fourth quarter revenue was up 4.7% year-on-year, predominately as result of continued strong improvement in data revenues.

At a time when the public sector is looking to rationalise costs, our advantage particularly comes into its own as demonstrated by our success, in January 2011 in being selected by the London Grid for Learning, a consortium of all 33 London local authorities, to power a new public sector network that will transform the delivery of public services in and around London. Key data contracts signed during the quarter included Hampshire County Council, to supply connectivity to local schools, Talk Talk and Knight Frank, the global residential and commercial property consultancy. Business data remains a key growth opportunity for us in 2011.

Capital Return Programme Update(1)

In our Q2 2010 financial results we announced an initial £700m Capital Return programme and a target leverage ratio of approximately 3.0x Net Debt to OCF over the next two to three years. So far, we have repurchased approximately 11.6m shares at a cost of £162m. We retain the authority for a further £213m of buybacks until August 2011.

5

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 fallen from 3.8x at the end of 2009 to 3.4x.

During the quarter, we also executed conversion hedges to effectively increase the strike price on 90% of our Convertible Senior Notes due 2016 from $19.22 to $35 for a cost of approximately £205m. The hedges are intended to reduce the potential dilution associated with the notes. The conversion hedges do not change the terms of the notes from a noteholder perspective, and do not alter the conversion date of November 15, 2016.

(1) OCF, Net debt, and Net debt to OCF are non-GAAP financial measure. See Appendix F for reconciliations of non-GAAP financial measures to their nearest GAAP equivalents.

RESULTS FOR THE THREE MONTHS ENDED DECEMBER 31, 2010

Note: Unless otherwise stated, all comparisons of financial and operating statistics are to the fourth quarter of 2009.

TOTAL REVENUE

Total revenue in the fourth quarter was up 6.6% to £1,003.8m due to growth in cable, mobile, business and non-cable.

CONSUMER SEGMENT

Cable

Cable revenue in the fourth quarter was up 6.7% at £682.8m reflecting 4.9% growth in cable ARPU to £47.51 and 1.6% growth in the cable customer base. Consumer fixed line telephony usage was higher than expected in the fourth quarter due to heavy snow which meant more customers stayed at home than usual and made fixed line calls. This partly contributed to the ARPU improvement.

Gross cable customer additions in the fourth quarter were up 4.0% to 206,600. Average monthly churn increased from 1.2% to 1.3%. The overall cable customer base increased to 4.8m, with net additions of 17,100 for the quarter which compares to 28,600 a year ago.

Mobile

Mobile revenue in the quarter was £148.3m, up 6.7%, reflecting ARPU growth driven by the increased number of contract customers.

Contract net additions for the quarter were 56,100 and at the quarter-end we had 1,210,800 contract subscribers representing 39% of total mobile products and growth of 27% in contract subscribers during the year.

The number of prepay net disconnections in the quarter was 54,200 compared to 98,300 in the same quarter last year. The loss of prepay subscribers reflects the competitive market and our strategy of focusing on contract due to the higher churn, low tariffs and lower overall lifetime value of prepay customers.

Non-cable

Non-cable revenue in the quarter was up 21.8% at £20.7m due to the growth in telephony line rental revenue, following our launch of wholesale line rental in the second half of 2009.

BUSINESS SEGMENT

Business revenue in the quarter was £152.0m, up 4.7%, mainly due to strong growth in data and wholesale revenues. Retail data revenue was up 9.3% to £62.4m, reflecting our successful strategy of focusing on higher margin data revenue and increasing demand for our data products. Wholesale revenue was up

6

15.2% at £43.3m mainly due to increased traffic across our existing customer base. Retail voice revenue was down 5.7% to £39.7m as a result of declining telephony usage and pricing. Local Area Network (“LAN”) Solutions revenue was down 23.5% at £6.5m due to reduced equipment sales and project revenues.

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

Operating costs (exclusive of depreciation and amortization) were £408.5m in the quarter, up 7.6% compared to total revenue growth of 6.6%. Consequently, total gross margin percentage(1) in the quarter declined slightly to 59.3% from 59.7%. Gross margin percentage for the full year was 59.4%, up 1.1 percentage points on 2009.

SG&A fell 1.5% to £191.7m in the quarter, mainly due to lower facilities costs being partially offset by increases in other areas. SG&A for the full year of £790.6m was up just 0.5% reflecting strong cost control.

(1) Total gross margin percentage is defined as total revenue less total operating costs, divided by total revenue.

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

OCF(2) increased to £403.6m in the quarter, up 9.9% mainly due to the growth in revenue. As a result, OCF margin(2) (OCF as a percentage of revenue) improved to 40.2% from 39.0%. OCF for the full year was up 12.0% to £1,510.2m with OCF margin at 39.0%, up from 36.8%.

(2) OCF and OCF margin are non-GAAP financial measures. See Appendix F for reconciliations of non-GAAP financial measures to their nearest GAAP equivalents.

OPERATING INCOME

Operating income in the quarter was £71.0m, up 9.2% mainly due to increased revenue and lower amortization, partially offset by higher operating costs, depreciation and restructuring and other charges. Operating income as a percentage of revenue was 7.1%, up from 6.9% .

Restructuring and other charges of £41.6m were incurred during the quarter compared to £9.8m in the same quarter last year. The charge in the quarter related principally to the payments made to exit long-term property leases for our main London office in Great Portland Street. This was part of the three-year cost saving programme we announced in November 2008.

Depreciation expense was up 11.6% at £254.3m primarily as a result of increases in depreciation in respect of new fixed assets, partially offset by fixed assets becoming fully depreciated. Amortization expense was £36.7m, down 38.6% mainly due to the cessation of amortization of certain intangible assets that became fully amortized in the fourth quarter of 2009.

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 £2.6m in the quarter and £22.8m for the year-to-date. 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 December 31, 2010 at £359m, which includes loans to fund its operations totaling £120m.

Virgin Media received £8.7m from UKTV in the form of net loan capital repayments during the year. However, the loan increased by £7.7m during the quarter. Virgin Media also received cash payments from UKTV in the quarter totaling £1.9m, and £25.7m in the year, which consisted of dividends, interest payments and payments for consortium tax relief.

7

NET INCOME FROM CONTINUING OPERATIONS

Net income from continuing operations for the quarter was £35.0m compared to a loss of £89.0m in the fourth quarter of 2009. The improvement was mainly due to higher operating income, lower loss on extinguishment of debt and increased income tax benefit. Income tax benefit increased mainly because, we concluded during 2010 that it was more likely than not that we would be able to utilize certain net operating loss carry forwards prior to their expiration, which will occur between 2020 and 2030, to reduce future U.S. federal income tax liabilities. Accordingly, we reduced the previously established valuation allowance on these net operating loss carry forwards to nil and recorded a federal deferred income tax benefit of £79.8 million.

CAPITAL EXPENDITURE

Fixed asset additions (accrual basis)(3) in the quarter were down 29.8% at £141.3m mainly due to lower spend on consumer premise equipment, scaleable infrastructure and support capital. The total purchase of fixed assets and intangible assets was down 3.3%.

For the full year, fixed asset additions (accrual basis)(3) were up 4.3% at £679.2m mainly due to increased spend on commercial and consumer premise equipment. The total purchase of fixed assets and intangible assets was up 10.6% at £628.4m, representing 16.2% of revenue. The increase was mainly due to the 4.3% increase in fixed asset additions (accrual basis) above in addition to the impact of timing of payments to suppliers.

(3) Fixed asset additions (accrual basis) is a non-GAAP financial measure. See Appendix F for reconciliations of non-GAAP financial measures to their nearest GAAP equivalents.

FREE CASH FLOW

Free Cash Flow(4) for the quarter was up 58.0% to £138.1m mainly due to higher OCF and lower total purchase of fixed assets and intangible assets. Net cash provided by operating activities was up 10.6% at £265.3m.

For the full year, Free Cash Flow was up 24.2% to £412.3m as increased OCF was partially offset by increased total purchase of fixed assets and intangible assets and increased net interest expense. Net cash provided by operating activities was up 16.1% at £1,037.6m.

(4) Free Cash Flow is a non-GAAP financial measure. See Appendix F for reconciliations of non-GAAP financial measures to their nearest GAAP equivalents.

DEBT

As of December 31, 2010, long term debt, net of £222m current portion, was £5,798m. Total debt consisted of £1,675m outstanding under our Senior Credit Facility, £2,068m of Senior Notes, £1,495m of Senior Secured Notes, £535m of Convertible Senior Notes and £247m of capital leases and other indebtedness. Cash and cash equivalents were £480m. Net debt(5) was therefore £5,541m.

Interest expense in the fourth quarter was £118.7m, down 4.1% due to a lower level of debt paying interest at fixed rates. Full year interest expense was £477.8m, up 5.0% mainly as a result of higher interest rates following refinancing activity that took place in 2009 and early 2010.

(5) Net debt is a non-GAAP financial measure. See Appendix F for reconciliations of non-GAAP financial measures to their nearest GAAP equivalents.

Bank amendment

On February 15, 2011, we received approval from our lenders to amend our Senior Credit Facilities agreement to increase the Company’s operational flexibility and provide additional options in accessing the capital markets, whilst continuing to underscore a commitment to financial discipline. The amendments do not affect the Company’s capital return programme announced in July 2010.

Words like “believe,” “anticipate,” “should,” “intend,” “plan,” “will,” “expects,” “estimates,” “projects,” “positioned,” “strategy,” and similar expressions identify these forward-looking statements, which involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements or industry results to be materially different from those contemplated, projected, forecasted, estimated or budgeted, whether expressed or implied, by these forward-looking statements. These factors, among others, include:

·                  the ability to compete with a range of other communications and content providers;

·                  our reliance on third-party suppliers and contractors to provide necessary hardware, software or operational support;

·                  the continued right to use the Virgin name and logo;

·                  the ability to manage customer churn;

·                  general economic conditions;

We assume no obligation to update our forward-looking statements to reflect actual results, changes in assumptions or changes in factors affecting these statements

Non-GAAP Financial Measures

We use non-GAAP financial measures with a view to providing investors with a better understanding of the operating results and underlying trends to measure past and future performance and liquidity. We evaluate operating performance and liquidity based on several non-GAAP financial measures, including (i) operating income before depreciation, amortization, goodwill and intangible asset impairments and restructuring and other charges (OCF), (ii) Free Cash Flow (FCF), (iii) fixed asset additions (accrual basis), and (iv) Net Debt, as we believe these are important measures of the operational strength of our business and our liquidity.

OCF is most directly comparable to the GAAP financial measure operating income. FCF is most directly comparable to the GAAP financial measure net cash provided by operating activities. Fixed asset additions (accrual basis) is most directly comparable to the GAAP financial measure purchase of fixed and intangible assets, as reported in our statements of cash flows.  Net Debt is most directly comparable to the GAAP financial measure long term debt (net of current portion). Since these non-GAAP financial measures are not calculated in accordance with GAAP, they should not be considered as substitutes for operating income (loss), net cash provided by operating activities, purchase of fixed and intangible assets and long term debt (net of current portion), respectively.

Please see Appendix F for a discussion of our use of non-GAAP financial measures and reconciliations to their nearest GAAP equivalents.
