If you’re non-binary and want a name that fits who you are, you can change your name in the UK with a deed poll - you do not need a Gender Recognition Certificate, a doctor’s letter, or anyone’s permission, and an unenrolled deed poll from £14.49 is legally valid and accepted by the passport office, DVLA, HMRC, banks, the NHS and your employer. The name change itself is genuinely straightforward; the trickier part is knowing the real-world limits on gender markers and titles, so this guide walks you through choosing your name, getting the document, adopting the Mx title and updating your records smoothly.
Choosing your name
There are no special rules for non-binary names - you have the same freedom as anyone else. You can pick a name that’s traditionally masculine, feminine, gender-neutral, invented or a play on your existing name. You can change your first name, your middle names, your surname, or all of them at once.
A few practical pointers worth keeping in mind:
- Test it out first. Many people use a chosen name informally for weeks or months before making it official. It’s a low-pressure way to be sure it feels right when others say it aloud.
- Stay within the rules. UK names can’t contain numbers or symbols, can’t be impossible to pronounce, can’t promote a business, and can’t be vulgar or implied to confer a rank or title you don’t hold (such as ‘Sir’ or ‘Lord’).
- Think about middle names. Some non-binary people keep a birth name as a middle name; others drop it entirely. Both are completely fine.
You don’t need to justify your choice to anyone. The deed poll records your decision; it doesn’t ask why.
The deed poll: how to make it official
A deed poll is the simple legal document that records your name change and lets organisations update their records. There are two types, and the distinction matters less than people fear.
An unenrolled deed poll is the standard route - around 98% of all UK name changes use one. It’s legally valid the moment it’s signed and witnessed, and it’s accepted by HM Passport Office, the DVLA, HMRC, the NHS, banks, employers and schools. It also keeps your change private, which many non-binary people prefer. Our professionally printed adult deed poll starts at £14.49, with same-day dispatch on orders placed before 3pm and free Royal Mail Tracked delivery. A solicitor would charge £150-£300+ for an identical document, so there’s no need to involve one.
Enrolment at the Royal Courts of Justice is optional and costs £53.05. It publishes your old and new names publicly in The London Gazette, takes 2-3 weeks, and adds no extra legal validity. For most people - and especially anyone who values privacy - it’s an unnecessary expense.
Signing it correctly
Anyone aged 16 or over can change their own name and sign their own deed poll. To be valid, your deed poll needs an independent adult witness (18+) - not a relative, partner or anyone living at your address. Sign in wet ink, and remember that the passport office, DVLA and banks all need the original signed document, never a photocopy. Order a spare original if you have many records to update at once. For a fuller walkthrough of the legal mechanics, our guide to legally changing your name when transitioning in the UK covers every step.
Adopting the Mx title
Mx (usually pronounced “mix” or “mux”) is the widely recognised gender-neutral title, and it’s a popular choice for non-binary people. Here’s the key thing to know: a title is not legally part of your name, so you do not need a deed poll to start using Mx. You simply tell organisations to update it.
Mx is accepted by HM Passport Office, the DVLA, HMRC, the NHS, most banks and the majority of large employers and retailers - it’s a standard option on most title drop-down menus now. A small number of smaller organisations still have outdated systems; if you hit one, asking for “no title” is a reliable fallback. For exactly how to switch your title across your records (and the wording to use), see our dedicated guide on changing your title to Mr, Mrs, Ms or Mx in 2026.
The passport and the gender-marker reality
This is where it’s important to be honest about the current law. As of 2026, UK passports only offer ‘M’ or ‘F’ gender markers - there is no ‘X’ option. The courts have considered the issue, but the policy has not changed. So while you can absolutely put your new name on your passport, you cannot yet record a non-binary gender marker on it.
What you can do:
- Update the name. Send HM Passport Office your original deed poll and apply as normal - changing only your name does not require a GRC, a doctor’s letter or any other gender-related evidence. A UK adult passport costs £102 online or £115.50 by post; Fast Track (1 week) is £192 and Premium (1 day) is £239.50.
- Understand what it takes to change the gender marker. Switching your passport’s ‘M’/‘F’ marker to the one that differs from your birth sex is a separate process and is not a free-choice or self-declaration system. HM Passport Office requires supporting evidence: a Gender Recognition Certificate, a new birth or adoption certificate showing your acquired gender, or a letter from your doctor or medical consultant confirming the change is likely to be permanent. For many non-binary people, being forced to pick between two binary markers - and to prove it - is a genuine and frustrating limitation.
- Use the title. Mx is available on UK passports, which helps even where the gender marker doesn’t.
Driving licence, banks and daily life
Updating your name elsewhere is the easy part - and most of it is free.
The DVLA driving licence name update is free; send the D1 form (or apply online) along with your deed poll. One quirk worth knowing: the DVLA driving licence number encodes a gender digit derived from your date of birth, and this is set internally rather than displayed as a marker. It doesn’t change with your title and isn’t something you select, so don’t be alarmed if it doesn’t reflect how you identify.
Banks, HMRC, the NHS, your employer and utility providers are all free to update too. A smooth order of operations is:
- Update your passport and driving licence first - these are your strongest proof-of-ID documents.
- Update your bank next, as new cards and statements then act as further proof for everyone else.
- Work through HMRC, the NHS (your GP surgery), your employer, pension, utilities and subscriptions.
Most organisations accept a clear photo or scan of your deed poll, but keep your original safe - the passport office, DVLA and banks may ask to see it. When you ask the NHS to update your records, you can also ask your GP to record your title as Mx; many surgeries can flag a preferred name and pronouns in their systems.
Frequently Asked Questions
Do non-binary people need a Gender Recognition Certificate to change their name?
No. A name change is entirely separate from legal gender recognition. A deed poll changes your name regardless of your gender or how you identify, and you never need a GRC, a diagnosis or a doctor’s letter to get one.
Can I get an ‘X’ gender marker on my UK passport?
Not currently. As of 2026, UK passports only offer ‘M’ or ‘F’. You can still update your name freely and use the Mx title, but the gender marker remains binary. Changing which of the two markers you hold is a separate process that requires supporting evidence (see below) - it isn’t a free choice.
Can I just pick the M or F marker I prefer on my passport?
Not by self-declaration. To be issued a marker that differs from your birth sex, HM Passport Office asks for one of: a Gender Recognition Certificate, a new birth or adoption certificate showing your acquired gender, or a letter from your doctor or medical consultant confirming the change is likely to be permanent. Changing only your name needs none of this.
Will an unenrolled deed poll be accepted everywhere?
Yes. An unenrolled deed poll is legally valid and accepted by HM Passport Office, the DVLA, HMRC, banks, the NHS, employers and schools. Around 98% of UK name changes are unenrolled, so it’s the standard, fully recognised route.
Do I need a deed poll just to use Mx?
No. A title isn’t legally part of your name, so you can adopt Mx simply by asking organisations to update it - no document required. You’d only need a deed poll if you’re also changing your actual name.
Can my witness be a friend?
Yes, as long as they’re an independent adult aged 18 or over who isn’t a relative, your partner, or someone living at your address. A friend, colleague or neighbour is ideal.
Is enrolment worth paying for?
For most non-binary people, no. Enrolment costs £53.05, takes 2-3 weeks and publishes your name change publicly in The London Gazette - the opposite of private. It adds no legal validity over an unenrolled deed poll, so it’s rarely worth it.
