Phone the population service to arrange your declaration no later than the day before you leave.
Have identity documents, departure date and your new address or destination details ready for the service to confirm the required evidence. If the whole household moves, national guidance says the household reference person makes the declaration. Ask about proof of deregistration, current fees and any further tax or insurance notifications; a departure-specific document list or fee is not available.
