Skip to contents of guide

Eligibility and fees

You can apply for British citizenship by ‘naturalisation’ if you:

  • are 18 or over
  • are married to, or in a civil partnership with, someone who is a British citizen
  • have lived in the UK for at least 3 years before the date of your application

You can apply as soon as you have one of the following:

  • a permanent residence document to prove you have permanent residence status
  • indefinite leave to remain in the UK
  • ‘settled status’ (also known as ‘indefinite leave to remain under the EU Settlement Scheme’)
  • indefinite leave to enter the UK (permission to move to the UK permanently from abroad)

You must also:

This is one way to apply for British citizenship. Check if you’re eligible another way - including through the Windrush scheme.

Residency requirements

You must have lived in the UK for at least 3 years before the date of your application.

You cannot include any time spent in the UK when you’re exempt from immigration control as a:

  • diplomat
  • member of a diplomat’s staff or household
  • member of visiting armed forces

You also should not have broken any UK immigration laws (for example living illegally in the UK).

Time you’ve spent outside the UK

To be eligible, you should not have:

  • spent more than 270 days outside the UK during the 3 years before your application
  • spent more than 90 days outside the UK in the last 12 months

You may be exempt from the residency requirements if your partner works abroad either for the UK government or an organisation closely linked to government.

When to apply

You must have been physically present in the UK exactly 3 years before the Home Office receives your application. Your application may be rejected if you cannot prove this.

Example

If the Home Office receives your application on 20 June 2022, but you left the UK on 10 June 2019 and returned to the UK on 25 June 2019, you will not qualify. You’ll need to wait until 24 June 2022 to apply.

The date the Home Office receives your application depends on how you apply. If you apply online, your application will be received on the same day. It will take longer if you apply by post.

How much it costs

It costs £1,330 to apply.

You must also pay £19.20 to have your biometric information (fingerprints and a photo) taken. You’ll be told how to do this after you’ve applied.

Children under 18

Your child is usually automatically a British citizen if they were born in the UK and when they were born either:

  • their other parent was a British citizen
  • you had indefinite leave to remain in the UK or permanent residence status

Otherwise, check if your children are eligible to apply for citizenship in another way.

If your partner has died

You cannot apply for citizenship as the partner of a British citizen if your partner has died. Check if you’re eligible another way - for example if you have indefinite leave to remain in the UK or permanent residence status.
