Virgin Media is to close its call centre at Liverpool's Albert Dock, it has announced.
Work handled by the centre, which employs 435 staff, will be transferred to its site in Swansea, south Wales.
Virgin said those staff it employed directly in Liverpool could be redeployed to Swansea or at sister sites in Manchester or Knowsley.
A spokesman for the company said a 90-day consultation period was now under way.
The current sites in Liverpool and Swansea are operated by IBM and their contract partners Adecco and Manpower.
The consolidated base in Swansea will move all operations in-house.
80 of the current position at Swansea will also be axed.
It is not clear if all of the current staff at Liverpool will be offered relocation to Swansea, Manchester or Knowsley. I suspect they are expecting many to leave
