What is British Naturalisation?

Naturalisation is the main way adults become British citizens. It is for people who have lived in the UK lawfully, usually hold Indefinite Leave to Remain or settled status, and meet the residence, language and good character requirements.

As a British citizen you can hold a British passport, live and work in the UK free of immigration control, vote in all UK elections, and pass on citizenship to children in many cases.

Most naturalisation decisions are made within around six months. Once approved, you attend a citizenship ceremony where you make an oath or affirmation and receive your certificate.

Usually settled status held for at least 12 months, a qualifying period of residence, time within the absence limits, passing the Life in the UK Test, meeting the English requirement, and being of good character.

Other Ways to Become British

Children can often be registered as British citizens rather than naturalised, for example where a parent becomes British or the child was born in the UK and has lived here long enough.

Some people born outside the UK to a British parent are already British by descent, or can register. We check whether you may already hold a claim to citizenship.

Partners of British citizens can usually naturalise after three years of residence rather than five, provided they hold settled status and meet the other rules.

We confirm whether naturalisation, registration or an existing claim to citizenship is the correct and fastest path for you or your child.

How it works

From First Call to Decision

A senior adviser reviews your status, your residence and your absences, then tells you honestly whether you qualify before you spend anything. We confirm the correct nationality route for you or your child.

We prepare your residence, absence, English, Life in the UK and good character evidence together, and help you choose suitable referees, closing the common gaps that lead to refusals.

We complete and submit the online application for you. You pay the citizenship fee at this stage, then attend a short biometric appointment at a service point.

The Home Office makes its decision, usually within around six months. Once approved, you attend a citizenship ceremony, take the oath and receive your certificate, then apply for a British passport.

Get it right first time

Where Cases Go Wrong

Being outside the UK for too long during the qualifying period is a leading reason citizenship applications are refused. We map every absence against the 450-day and 90-day limits and advise on the best time to apply.

Undeclared cautions, unpaid tax, or previous immigration breaches can lead to refusal on good character grounds. We review your history frankly and advise on how any issues should be handled.

A forgotten Life in the UK Test, an expired English test or unsuitable referees cause avoidable delays and refusals. We work from a checklist tailored to your case so nothing is left out.

FAQs

Frequently Asked Questions

Most people need to have held Indefinite Leave to Remain or settled status for at least 12 months before applying to naturalise. Spouses of British citizens can sometimes apply as soon as they have settled status, if they meet the residence rules.

The UK allows dual nationality, so becoming British does not require you to give up your existing citizenship. However, you should check whether your country of origin permits dual nationality, as some do not.

For naturalisation you generally should not have more than 450 days of absence in the five-year period, and no more than 90 days in the final 12 months. The Home Office can sometimes exercise discretion on excess absences.

 

 

If your application is refused, the Home Office will set out its reasons. Depending on the ground, you may be able to request a reconsideration or reapply once the issue is resolved. We review the decision with you and advise on the strongest next step.

Often yes. Children may be able to register as British citizens, particularly where a parent becomes British or the child was born in the UK. We assess each child's position and can handle their applications alongside yours.
