Telecoms giant Virgin Media is to close a number of sites with the loss of hundreds of jobs.
The company, which employs 14,000 workers at more than 100 sites, said more than 500 jobs will be lost, with a call centre in Swansea and a site in Nottingham set to close over the next two years. The firm has also confirmed that it plans to centralise its operations to Manchester.
The number of Customer Operations sites will also be cut from eight to four, with centres in Wythenshawe, Sheffield, Birmingham and Stockton (Teeside) remaining.
Tom Mockridge, chief executive of Virgin Media, said: "Last year Virgin Media began a three-year property investment programme to create fewer, higher quality work places to better support our people, our business and growing customer base.
"As a result, we plan to invest an additional £40 million over the next three years to refurbish key sites and acquire new alternative sites.
"As part of this programme we intend to create four regional customer operations hubs while also increasing the flexibility of our customer services resources.We have also proposed the closure of a small number of our offices over the next two years including our call centre in Swansea and our current site in Nottingham.
"We will be increasing our presence in Wythenshawe, near Manchester, and refurbishing that site. We also propose acquiring a major new building in the Reading/M4 corridor area for our people presently based in Hook, Langley, Slough and Winnersh.
"We also plan to acquire smaller, better sites in Bellshill and Nottingham.
"Together, these changes will help deliver a more agile, digitally oriented experience which our customers increasingly expect as standard.
"We are now working with and supporting all employees who have been asked to relocate, who may be in a role at risk of redundancy or who may wish to take another role with Virgin Media or one of our partners."
