We're going to carry out some essential maintenance on our systems so we want to let you know in advance.

• 22:00 on Saturday 25 September to 03:00 on Sunday 26 September 2021.

Our online service will be unavailable during this time.

This means you won't be able to log in or apply for a new account.

Also, if you hold Premium Bonds, you'll be unable to update your prize options while this work takes place.

Thank you for your patience.
