To change the name on a UK bank account, you show your bank your deed poll (or your marriage certificate, if you have taken a spouse's surname) and ask it to update your details. Most banks accept a deed poll on its own. Your account number, sort code, direct debits and standing orders all stay the same; only the name changes, and the bank sends new cards in that name.
How the process works at different banks
High-street banks such as Barclays, HSBC, Lloyds, NatWest and Nationwide often ask you to visit a branch with your deed poll. Some accept a certified copy; others want to see the original. Check the bank's website or call before you go, as the rules differ and change. A branch visit is usually quick: staff check the deed poll, update your records and order new cards.
App-based banks such as Monzo, Starling and Revolut usually handle it in the app or through support chat, where you upload a photo of your deed poll. It tends to be faster and needs no branch visit.
For a joint account, the bank may want both account holders involved, even though only one name is changing.
One thing to check before you start: most banks accept an unenrolled deed poll, but GOV.UK warns that some banks only accept an enrolled one. If yours does, ask them to confirm it in writing. Our guide to enrolled and unenrolled deed polls explains the difference.

What changes and what stays the same
Your account number, sort code and online banking login do not change. Direct debits, standing orders and payments into the account carry on without interruption, so you do not need to tell the people who pay you or the companies you pay. New debit and credit cards arrive in your new name, usually within five to seven working days, and your old cards normally keep working until then.
Your credit file is not harmed. The credit reference agencies link your old and new names from the information your bank reports.
Update your bank early
Your bank card is used as everyday ID, and the Passport Office can ask for evidence that you are using your new name, such as a bank statement. Updating your bank near the start makes the rest of the process easier.
Other accounts to update
Each bank and building society needs telling separately, and so do credit card providers, savings and investment accounts, and your mortgage lender. A mortgage is not affected by the name change; only the name on the account is updated. Payment services such as PayPal and Apple Pay are updated through their own settings or support teams.
