Who can register

Only customers named on the account can register. This means that whilst most customers can use Self-Serve, there are some restrictions.

Self-Serve is unavailable for:

  • Mortgage accounts held only in the name of a Limited Company.
  • Individuals who have a third party authority or power of attorney for someone else’s account.
  • Anyone acting on behalf of a deceased customer.
  • Accounts that have redeemed (paid off).


How to register for Self-Serve

You’ll need to create a username and password. These details will be needed each time you sign in.

You’ll need to confirm the following information when registering for the first time:

  • Your mortgage account number (see your annual mortgage statement or a recent letter we’ve sent you).
  • The postcode of your mortgaged property (the ‘security address’).
  • Your date of birth.
  • The amount of your most recent mortgage payment (you can usually find this on your most recent bank statement).

For joint accounts, each person will need to register individually to use the service.

Once you’ve registered for Self-Serve you can sign in to access your account at any time.

Making debit card payments

Debit card payments made via Self-Serve after 8:30pm on weekdays, after 5pm on Saturday or after 7:30pm on Sunday are usually applied to your account the following day.

However, if you make your payment via Self-Serve on the last day of the month and that day is a Saturday or Sunday, payments made up until 9pm will be applied to your account on the same day.

You’ll see an immediate confirmation on screen that we’ve taken your payment. However, depending on when you make a payment, it may take up to 48 hours to show as a recent payment in Self-Serve.

If your account is in arrears, you may be unable to make your card payment via Self-Serve. If we don’t accept your debit card payment via Self-Serve, you’ll see a prompt asking you to call us instead.
