Number Porting

Porting BT, Energis, Virgin Media (Telewest/NTL) VoIP numbers and Directory Enquiries

It is now possible to port all BT and Virgin Media geographic area code telephone numbers. Non-geographic numbers beginning with 08 (e.g 0800, 0870, 0845) supplied by BT or Energis can also be ported. We regret that we cannot port Virgin Media non-geographic numbers beginning with 08.

We are also able to port numbers from some existing VoIP providers such as Sipgate (providing you have their agreement to do so).

This takes up to 3 days to complete once permission is granted.

To port a BT, Virgin Media (Telewest/ NTL), VoIP or Energis number to Gradwell dot com we require the following (please note that the downloadable form on this page is in MS Excel format).

NB: Any numbers with services attached/associated to them (e.g. fax, broadband, alarm systems, credit card machines) will be ceased when the number is ported over to Gradwell. If this is the case you must arrange to transfer these services to new number with BT or Virgin Media before attempting to port.
