Mx (pronounced "mix" or "mux") is a gender-neutral title that does not indicate the holder's gender. It is increasingly accepted by UK organisations and institutions as an alternative to Mr, Mrs, Miss, or Ms, and is particularly used by non-binary people, genderfluid people, and anyone who prefers not to be identified by a gendered title in official contexts.
Changing your title to Mx is not technically a name change — your name stays the same — but a deed poll can play a useful supporting role. Many organisations are more responsive when a title change request is accompanied by a deed poll, even if the name itself is not changing. Some people include their preferred title in a note accompanying their deed poll when they notify organisations of a name change, making the request clear and formal. Regardless, you do not need a deed poll specifically to request a title change — you can request Mx directly from each organisation without any formal document.
The good news is that acceptance of Mx is now widespread across major UK institutions. The Passport Office offers Mx as a title on UK passports. The DVLA accepts Mx on driving licences. Most major high-street banks — including Lloyds, HSBC, Barclays, Nationwide, and NatWest — accept Mx. The NHS accepts Mx, and GP surgeries can update patient records accordingly. HMRC and the DWP also recognise Mx. Most government services that previously required a binary title have now been updated to include Mx as an option.
Where you may encounter resistance is with older computer systems, some insurance providers, or smaller local organisations that have not updated their forms or records to include Mx. In these situations, it is reasonable to request the change in writing, ask to escalate to a manager or equality officer, and cite the Equality Act 2010 if the refusal appears to relate to a protected characteristic. Progress has been significant, and most reasonable organisations will accommodate the request.
If you are also changing your name at the same time — which many people do alongside a title change — this service generates a deed poll for £14.99. When you notify organisations of your name change, you can simultaneously request the title update to Mx.
