Changing your name with the NHS and your GP

How to change your name on your NHS record#

Tell your GP practice. The NHS App's help pages say that if you want to update personal details such as your name or address, you contact your GP surgery, and the NHS website's page on registering with a GP says the same for anyone who needs to update their details without changing surgery. The app's help makes no distinction between a new name from marriage, from divorce or from a deed poll.

So the NHS App is not where a name is changed; its help pages send you back to your practice.

What your practice asks for#

Each practice sets its own procedure. Primary Care Support England, which processes GP registrations on behalf of NHS England, says a practice sends a change of name to it through the GP Links system, and that it does not need to be told what evidence the practice has seen. Answering a practice's question about a transgender patient's new name, it says each practice defines its own procedure on evidence, that there is no legal requirement to ask for any, and that asking is considered best practice.

So take the document that records the change, your deed poll or your marriage certificate, and ask what the practice needs to see. If it wants to keep something, a certified copy lets you keep the original. Where the forename is changing, Primary Care Support England advises practices to confirm in a note that the new details are correct, and says it may query a change that looks like a data quality problem.

Your NHS number stays the same#

A new name does not bring a new number. The NHS website says your NHS number is unique to you and that it is "valid for life unless you're assigned a new number due to a reason like adoption or gender reassignment". A change of name is sent as an amendment to your existing registration, and the number goes on with it. You do not need your NHS number to use NHS services, but the NHS App shows it under your name, and it is usually on letters from your practice or hospital.

How the change reaches the NHS App and hospitals#

Your practice's amendment updates the Personal Demographics Service, which NHS England describes as the national master database of all NHS patients in England, Wales and the Isle of Man. It holds each patient's name, address, date of birth and NHS number, and NHS England's policy manual says Primary Care Support England keeps it in line with each practice's list of patients.

The NHS App is one of the services that reads it. NHS England says the database is used in all GP settings and in the vast majority of hospital and other secondary care settings, and that any organisation keeping its own copy of patients' details must synchronise it regularly. None of the NHS guidance we read gives a time for a new name to appear.

Dentists, opticians and hospitals#

Each keeps its own records. NHS England's guidance on getting a copy of your health records says the request goes to the organisation that holds them, such as your GP practice, optician or dentist, and for hospital records to the hospital trust. Tell your dentist and optician at your next appointment, and any hospital department that is treating you, then check the name on the next letter each one sends. A GHIC or UK EHIC is separate again: changing the name on your GHIC.

Scotland#

NHS inform says to contact your GP practice if you would like to change your name and title within the NHS. Scotland identifies patients by a 10-digit CHI number, held on the Community Health Index, and the GP registration form NHS inform provides asks for a previous surname. If you register with a new practice, give your old name there too.

Wales#

Patients in Wales are on the same Personal Demographics Service as patients in England, and NHS numbers are issued in the same way. NHS 111 Wales's questions and answers on GPs say nothing about a change of name, so start with your practice.

Northern Ireland#

Northern Ireland has its own system. nidirect points patients to the Business Services Organisation (BSO) for GP registration forms, and BSO's page says that to change your name on your medical card and in your doctor's surgery you complete its form and return it to BSO with appropriate documentation.

Its form for adults, for a change "other than on marriage" and last revised in June 2009, asks you to attach a copy of your birth certificate, a statutory declaration, a deed poll "drawn up by a solicitor" or a civil partnership certificate. Its form for children, from 2021, asks for documents such as a deed poll enrolled with the Northern Ireland courts or a letter from the solicitor who dealt with it, and says deed polls issued outside Northern Ireland must be registered with the Northern Ireland courts. People aged 16 or 17 use the adult form. If your deed poll was not drawn up by a solicitor, ask BSO what it will accept before you post anything; a statutory declaration is also on its adult list.

Changing the gender on your NHS record#

Primary Care Support England's guidance for practices, as it stood on 29 September 2026, lets an adult change the gender marker on their record. The usual route gives a new NHS number and a new registration, with the old records transferred; the practice must first explain that this cannot be reversed and can mean losing the old record, problems with screening and losing a place on waiting lists. An adult can instead change the marker and keep their NHS number. After an independent review, the Secretary of State for Health and Social Care directed that gender markers are no longer changed for anyone under 18, though a child's name and title still can be. The guidance notes that NHS England is reviewing the process. Changing your name when you transition covers the other records.
