How to Change Your Last Name in the UK

Reviewed June 2026 · 6-minute read
In the UK, your "last name" and your "surname" are exactly the same thing — and the legal process for changing either is identical. Whether you're getting married, reverting to your maiden name after a divorce, or simply want a fresh start, this guide walks you through every step.
Knowing how to change your last name in the UK can feel daunting, but it's actually one of the more straightforward legal processes available to UK residents. There's no court appearance, no judge, and no lengthy waiting period. In most cases, all you need is a deed poll and a little patience while your records are updated.
How to Change Your Last Name by Deed Poll
A deed poll is the standard legal document used to change your name in the UK. It's a written declaration that you're abandoning your old name and adopting a new one. Once signed and witnessed, it's legally binding and accepted by almost every official body — from HMRC to the DVLA.
You have two options: an unenrolled deed poll (created privately) or an enrolled deed poll (registered with the Royal Courts of Justice). "Most UK banks, HM Passport Office, the DVLA and HMRC accept a correctly executed unenrolled deed poll." use the unenrolled route — it's faster, cheaper, and equally valid for updating your passport, driving licence, and bank accounts.
To create a deed poll, you'll need to:
- Draft or generate your deed poll document, clearly stating your current name, your new name, and your intention to use the new name exclusively going forward.
- Sign it in the presence of an independent adult witness (someone who isn't a family member and doesn't share your address).
- Have your witness sign and provide their full name and address.
That's it. Your deed poll is now a valid legal document. Print several copies — you'll need them when notifying different organisations.
How to Change Your Last Name After Marriage
If you've recently married and want to take your spouse's surname (or double-barrel both names), you don't need a deed poll at all. Your marriage certificate is sufficient proof of your new name.
Simply present your original marriage certificate — or a certified copy — to each organisation you need to update. Most will accept it alongside a covering letter and a copy of your current photo ID.
Common organisations to notify after marriage include:
- His Majesty's Passport Office (allow 6–10 weeks)
- DVLA for your driving licence
- Your employer and pension provider
- Banks, building societies, and credit card providers
- HMRC and the Department for Work and Pensions
- Your GP, dentist, and any other healthcare providers
- Electoral roll (update online via Gov.uk)
- Utility companies and subscriptions
If you'd prefer to double-barrel your surname rather than take your spouse's name outright, you will need a deed poll — a marriage certificate only covers the straightforward name swap.
How to Revert to Your Maiden Name (After Divorce or Separation)
Going back to your maiden name after a divorce or separation is entirely your right — and it's often simpler than people expect.
If your divorce is finalised, you can use your decree absolute (or, for divorces after April 2022, your final order) together with your original marriage certificate to revert to your maiden name. Most organisations will accept these two documents without requiring anything further.
If you'd prefer not to share your divorce paperwork — which is entirely understandable — or if you separated without divorcing, a deed poll is the cleaner option. It gives you a single, self-contained document to present everywhere, with no need to explain your personal circumstances.
Either way, there's no legal requirement to wait until the divorce is finalised. You can change your name by deed poll at any point during or after a separation.
How to Legally Change Your Last Name — Full Process
Here's the complete process for anyone asking how do I change my last name in the UK from scratch:
- 1
Prepare your deed poll
Use an online service to generate a professionally worded document, or draft one yourself using the correct legal wording.
- 2
Sign in front of a witness
Your witness must be over 18, independent, and present when you sign. Both of you must sign and date the document.
- 3
Make certified copies
Print multiple copies of the signed deed poll. Some organisations may ask to keep a copy.
- 4
Update your passport first
A passport in your new name makes everything else easier, as it becomes your primary photo ID. Apply via the Gov.uk passport service.
- 5
Update your driving licence
Notify the DVLA online or by post. There's no fee for a name change.
- 6
Notify financial institutions
Contact each bank, building society, and insurer individually — they each have their own process.
- 7
Inform HMRC
Update your name for tax purposes online or by phone. Your National Insurance number stays the same.
- 8
Update everything else
Work through the full list of organisations, starting with the most important and working down.
There's no legal time limit on when you must complete these updates, but it's sensible to work through the list methodically over the weeks following your name change to avoid inconsistencies on official records.
Documents to Update After Changing Your Last Name
Once your deed poll is signed, work through this checklist. Tackle the items in roughly this order — a passport or driving licence in your new name makes it much easier to satisfy ID checks elsewhere.
| Document / Organisation | How to Update | Typical Timescale |
|---|---|---|
| Passport | Apply online via Gov.uk | 6–10 weeks |
| Driving licence | DVLA online or by post (D1 form) | 2–4 weeks |
| Bank accounts | In branch or by post with deed poll | 1–2 weeks |
| HMRC | Phone or online self-assessment account | 2–5 working days |
| Electoral roll | Register to vote online via Gov.uk | Immediate |
| GP / dentist | Contact the practice directly | Varies |
| Employer / payroll | HR department | Next payroll run |
| Pension provider | Contact provider directly | 1–4 weeks |
| Utility companies | Phone or online account | 1–5 working days |
| Subscriptions & loyalty cards | Online account settings | Immediate |
Keep a copy of your deed poll with each letter or application. Some organisations will return the original; others may keep a copy. Print at least six copies to avoid delays.
Frequently Asked Questions
How do I change back to my maiden name in the UK?
You can revert to your maiden name using your decree absolute (or final order) and original marriage certificate — no deed poll needed if your divorce is finalised. If you'd prefer a single document or haven't divorced, a deed poll works just as well and keeps your personal circumstances private.
Is a deed poll legally binding in the UK?
Yes. A correctly executed deed poll — signed and witnessed — is recognised as legal evidence of a name change by all UK government departments, banks, and most other institutions. You don't need to register it with a court unless you specifically want a public record.
How much does it cost to change your last name in the UK?
There's no government fee to change your name by deed poll. The cost of updating your passport (around £82.50 for a standard adult renewal) and your driving licence (free for a name change) are the main expenses. Any deed poll service fees vary by provider.
Can I change my child's last name in the UK?
Yes, but all individuals with parental responsibility must consent. For children under 16, a parent or guardian applies for the deed poll on their behalf. Children aged 16 and 17 can apply for their own deed poll but may still need parental consent depending on the circumstances.
Do I need to change my name on my passport straight away?
Technically, you can continue to travel on a passport in your old name as long as it remains valid, but it's strongly advised to update it as soon as possible — especially if the name on your ticket or booking differs from your passport. Many airlines and border agencies require them to match exactly.
How long does it take to change your last name in the UK?
The deed poll itself can be created and signed within a single day. Updating all your official documents typically takes between one and three months, depending on passport processing times and how many organisations you need to contact.
