Changing address with bank

plunt

i reckon its checked against the electoral roll. Sign up to Noddle.co.uk and have a look at your credit file. Granted its a month delayed on their but atleast its free!

Banks will inform credit reference agencies of change in address, so as far as credit checks are concerned, prospective lenders should see every address that you've linked your bank to.

After my move last August I have a note on my credit file with Noddle saying this move was first confirmed on 30 Aug and last confirmed on 10 Sept. It also says that Santander was the company that made this last confirmation.
