Before you change any payments
Don't cancel the direct debit before you notify them. Suppliers normally take a final reading and settle the account themselves, and cancelling early can leave the energy or water supply unbilled and in arrears.
Don't want to do this alone?
Notifying companies one by one takes weeks. Alenity can notify Southern Water and all the others for you, drafting the messages, sending them, and handling the replies.
