Well after an e-mail back to say that it didn't seem like it was working as it was still on 2Mbs after 3 days I was told to wait the full 10 days as it can take that long before the profile gets released.
After reading that this morning, i did another test and low and behold, the profile is now on 7.15Mbs and getting just over 7Mbs on the speed tester which is great.
I can now watch HD on demand and do some remote working again, and cancel my 12Mbs Three tethering connection.
The only issue I have left is that the HH4 has really poor wireless penetration so I'm going to have to cable in another AP to extend the range and I now have to unplug the router to move it away from the master socket that it has been sitting in for a few weeks and back to the extension socket and hope it doesn't cause a drop in IP profile.
I would suggest delaying your move for at least a day or so to let profile settle otherwise you may by moving so quickly cause a problem - it may not but up to you
