Fuss-free and fast way to amend your details

There is no need to call us, you can now amend your personal details using your Mobile Banking app or Online Banking :

• ​Name and title

• Address

• Email

• Mobile number

• National Insurance number

And here’s what you’ll need:

To update your address:

• A valid UK driving license or government-issued photo ID (like a passport or ID card)

AND

• A recent proof of address (dated within the last 3 months), such as a bank statement, utility bill, council tax bill, credit card statement, or tax return.

To update your name or title:

• A valid UK driving license or photo ID

AND

• Proof of your full name change (e.g. marriage certificate, deed poll, or decree nisi).
  If it’s just a correction (like a typo), you can upload a recent proof of address instead.

This new approach means no more calling, just a few clicks and you're done.
