Need address proof

Hi guys. My wife recieved her Monzo card at a Cheltenham address but has been living with me at my Surrey address and has only recently changed addresses with Monzo.
She now needs to apply for a spouse visa and needs to prove that she has been at my address with me since 2020, which she has,. Is there acway that any online activity will show a Surrey address instead of a Cheltenham one?

You can contact customer support & ask for a proof of address letter I believe.

You can ask for an account ownership letter which will confirm the address and I believe how long the account has been opened for.

It wouldn’t specifically say Mrs Monzo has been living at said address for X years.

Council tax bill may confirm the length of time being registered at that address.

Did you stop getting the council tax discount when she moved in?
