Changing your name in the UK is a straightforward legal process. You do not need a court order, a solicitor, or government approval. The standard method is a deed poll — a legal document in which you formally declare that you are abandoning your previous name and intending to use your new name in all circumstances. Once signed by you and two adult witnesses, the deed poll is your legal evidence of the name change and can be presented to any organisation.
The process has three stages. First, create and sign your deed poll. This service generates a correctly worded deed poll instantly — you fill in the form, pay £14.99, download the PDF, print it, and sign it in front of two adult witnesses who are not close relatives. Second, work through the organisations that need to be notified. Start with the documents you use most often: your passport or driving licence, your bank, and your employer. Third, update the remaining organisations over time — HMRC, your GP, your pension provider, utility companies, and any other body that holds records under your old name.
There is no deadline for updating your records — you can work through organisations at your own pace. Many people update their most important documents (passport, driving licence) quickly and work through the rest over several weeks or months. Your deed poll remains valid indefinitely, so you can use it to update any organisation at any time after signing.
