After a couple more e-mails to the CEO Office and waiting for them to investigate the issue with Openreach I have had an official response regarding the problem, although not the ideal solution. This is the response from BT (Given I am trying to swap ISP from Virgin to O2),
"Openreach have advised there are 2 solutions to the matter regarding your application for Broadband.
The quickest solution would be to renumber the telephone service with a telephone number that is recognised as a Haydon number.
If you do not wish to change your telephone number, there are ongoing discussions with O2 for long term solutions. 1 is for O2 to install a second DSLAM into Haydon Wick which will then recognise Blunsdon numbers as on Haydon. However power and space is limited. Openreach are also looking into changing the number structuring. Both these are long term solutions, especially the latter and I have been advised it is hard to give any timescale on them."
So basically if you want to swap ISP after the Exchange Migration it appears you need a new number.
