House move - provisional phone number

[#1]

I recently moved house, and was given a provisional phone number (question 62662843)
From what I can tell, this has become my actual number, so I just need confirmation that this is definitely the case and I won't be switched back to my old number at any point?... (I need to arrange for the intercom in my flat to be redirected to the home phone at a cost of £35, so would prefer to only have to do this once!)

Hi dfunked,
Everything phone wise is now active on your account, and I can confirm the number that you've been issued is the one ending 385 and that won't change (unless you request a renumber of course).
Hope that helps.
