Moving to the UK is an opportunity for many people to reconsider their name, whether to adopt a name that is easier for British colleagues and institutions to handle, to align their name with their identity, or simply to make a fresh start. Non-UK citizens living in the UK can change their name by deed poll in exactly the same way as British nationals. A deed poll is not restricted to UK citizens; it is available to any adult resident in England, Wales, or Northern Ireland.
Once signed and witnessed, a deed poll generated here is valid as evidence of a name change with UK-based organisations: banks, employers, the NHS, HMRC, and so on. You can use it to update your records with the organisations that affect your everyday life in the UK. You can also use it to apply for changes to any UK-issued documents, such as a Biometric Residence Permit (BRP), or, if you are a British citizen, a British passport.
There is an important limitation to understand. A UK deed poll changes your name in UK records only. It does not change the name on your passport or national ID documents from your home country. Your country of origin's authorities will not recognise a UK deed poll as a basis for changing their records; you would need to go through your home country's own name change process for that. This can create a discrepancy between the name on your UK records and the name on your foreign passport, which some organisations (particularly the Home Office or when dealing with international matters) may query.
For most people living and working in the UK, the practical approach is to update UK-specific records with the deed poll (bank, employer, NHS, HMRC) while keeping home-country documents in their original name. Many people live comfortably with this arrangement. If you want full alignment across all documents, the home-country process would need to run in parallel.
If you hold a Biometric Residence Permit (BRP) or are in the process of applying for Indefinite Leave to Remain or British citizenship, a name change can add complexity. Contact UK Visas and Immigration (UKVI) to understand the implications before changing your name, or to notify them afterwards if you have already done so.
