Virgin Media TV and broadband customers in the City of Westminster will be forced to switch providers next year, it has been revealed.
The cable broadband provider has been looking to upgrade its rented analogue cable platform in central London for around a decade, but has now abandoned the plan.
With the digital switchover looming, Virgin Media has instead opted to withdraw from Westminster altogether.
A Virgin Media spokesperson told ISPreview.co.uk that from January 2012, the firm would no longer be able to provide its existing broadband and analogue TV services to homes in the borough.
"We use BT's infrastructure to deliver services in Westminster and are unable to upgrade the network and deliver our own next-generation digital services at a reasonable cost.
"We are speaking to our customers now to ensure they have plenty of time to decide on an alternative service or provider and will do everything we can to help them make the switch."
Virgin Media is continuing to expand its network in other areas of the UK, announcing plans this week to complete its cable network in Southampton.
