Take proof of the name change to a Nationwide branch, or complete the change-of-name form and post it with a certified copy of your evidence.
Evidence to prepare
- Proof appropriate to the reason for the change, including deed poll/statutory declaration for relevant changes.
Evidence rules can differ by product and by the reason for the name change. A deed poll is evidence of a change of name; it does not override a bank's customer-identification requirements.
Frequently asked questions
What is the official source for changing my name with Nationwide Building Society?
This guide was checked against Nationwide Building Society's own published customer guidance on 2026-09-09. Use the official-source link on this page before submitting documents because bank procedures can change.
Will an unenrolled deed poll always be accepted on its own?
Not necessarily. Banks set their own evidence policies. Some accept an unenrolled deed poll directly, while others require extra ID in the new name or another supporting document.
Should I send an original deed poll by post?
Follow Nationwide Building Society's current instructions. Some banks ask for originals, some accept certified copies and some provide a digital upload route. Do not post irreplaceable identity documents unless the bank specifically tells you to.
Need proof of a name change?
You can prepare an unenrolled deed poll yourself for free using GOV.UK guidance. Our paid service is for document preparation and support; individual organisations decide what evidence they will accept.
