For security reasons we cannot change a bank account over the telephone.
You can scan and email our authority for payment of pension form to change your UK bank account.

If you do want to change the bank account into which your pension is paid monthly, we recommend that you keep your old account open until the new one has received a payment, as we ‘cut off’ the accounts used for our monthly pension payments a couple of weeks before the payments are actually made.
Please make sure you sign the form, as we need your signature to authorise this change.
