I just took the joint account approach - I changed my bank account into joint account with his passport and our joint council tax bill - you MUST inform council tax as you lose rights to discount etc and they send you a new bill immediatly with both names - its the best form of ID/proof of address, I wrote to them before he arrived so had the letter here ready!

We are waiting to hear back about the account -they said they'd have to check him (how???) and he may not have full use rights of the account in the beginning.....
