Change of Address: who do I tell?

[BATS]

My fiance is living at a different address to the one he put down on the visa application from because our house isn't ready yet we are living with my parents. Who do we have to inform?

I don't think you do need to inform anyone, unless there is a requirement to register from the Police, and that will depend upon the person's nationality.

When the marriage has happened form FLR(M) will need to be used to get the 2-year spouse visa, and that will obviously need the current address entered on to it.
