How to apply for British citizenship

Set out below is key information in respect of applying for British citizenship in the following areas:

Can I apply for British citizenship?

Whether you are eligible to apply for British citizenship will depend on the circumstances.

If you have settled status under the EU Settlement Scheme, then you can usually apply for British citizenship once you have held this for at least 12 months.

If you have lived in the UK for 5 years under a valid visa or series of visas, then you can apply for indefinite leave to remain (ILR). Once you have ILR, you can usually apply for British citizenship after living in the UK for another 12 months.

If your spouse or civil partner is a British citizen, you can apply if you have lived in the UK for at least the last 3 years and you have either indefinite leave to remain or settled status under the EU Settlement Scheme.

You may also be able to apply if you have a British parent, hold a different type of British nationality (e.g. you are a British overseas citizen), you qualify for the Windrush scheme, or you have previously renounced your British citizenship and wish to have it restored.

Our expert British citizenship and naturalisation lawyers will be happy to advise you on whether you are eligible to apply.

What does it mean to “apply for British naturalisation”?

Naturalisation is the process of becoming a British citizen. While people sometimes talk about “applying for British naturalisation” what you are really applying for is ‘British citizenship by naturalisation’.

British citizenship and naturalisation eligibility requirements

In order to be granted British Citizenship through naturalisation, the following criteria must be satisfied:

English Language

The British Government will only grant citizenship to individuals that are able to communicate with the wider community and are equipped to play a part in the wider community. Being able to speak English is a very important part of this. The below sets out how you can satisfy this requirement:

  1. being a national of a majority English speaking country; or
  2. passing an approved English language test to level B1 or above
    • you will need to achieve an English level B1, B2, C1 or C2 level qualification in order to satisfy the requirement
    • a list containing the approved tests and contact details for the test centres can be found in the attached Appendix 1; or
  3. holding a degree that was taught in English and is equivalent to a UK bachelor’s degree or above.

Life in the UK Test

The British Government see becoming a British Citizen as an important commitment and requires applicants to accept the responsibilities which go with citizenship and to respect the laws, values and traditions of the UK. The way that they require applicants to demonstrate this is by successfully passing the Life in the UK Test.

Once you feel confident that you have sufficient knowledge of Life in the UK, you may apply to take a test at a Life in the UK Test Centre.

Once you are registered at a Test Centre, you can take the Life in the UK Test. The fee is payable directly to the Test Centre.

The test will be taken on a computer. You will be given an opportunity to practice using the equipment and have an option to complete a short trial test before beginning the Life in the UK Test. The test will last for up to 45 minutes and comprise 24 questions based on the handbook Life in the United Kingdom: A Journey to Citizenship.

Support will be available at test centres for people with limited reading and writing ability or who lack basic IT skills.

If you pass the test, you will be given a letter that verifies your success. This should be attached to your application for naturalisation. The test results will also be sent to the Home Office electronically.

If you are not successful, you may book and take a further test. There is no limit on the number of times you may take the test. You must pay an additional fee each time you take it. Since the questions set are drawn randomly from a large bank of questions, any further test will be different from the earlier one that you took.

Presence in the UK at the start of the qualifying period

An applicant for naturalisation must have been physically present in the UK at the start of the qualifying period.

The start of the qualifying period is the day after the corresponding application date for naturalisation, e.g. if the application date is 5 January, the qualifying period starts on 6 January, 5 years earlier.

The date of the application is the date it is received by the appropriate receiving authority. It is therefore advisable to submit the application using a trackable method with a guaranteed delivery date (such as special delivery) and to check that the applicant was physically in the UK at the beginning of the qualifying period, based on the date of delivery.

Residence Requirement

Before you can apply for citizenship you will need to demonstrate that you have been lawfully resident in the UK for the last 5 years and that you have been free from immigration time restrictions during the last 12 months of the 5 year qualifying period.

To satisfy the residence requirement, you should not have been absent for more than 90 days in the last 12 months.

You should not have been outside the UK for more than 450 days in the 5 year qualifying period.

There is discretion to disregard absences in excess of the limits if there are compelling reasons. If you have absences in excess of 450 days, please advise us.


The British Government will not allow a citizenship application to succeed if they do not deem the applicant to be of “good character”.

If you have any criminal convictions, adverse immigration history, or any other issues that you feel may affect your application, please advise us immediately.


The application must be endorsed by two referees.

One referee should be a person of any nationality who has professional standing. The second referee should be the holder of a British citizen passport and:

  • a person of professional standing, or
  • a person over the age of 25

All referees must also:

  • not be related to the applicant or each other
  • not be representing the applicant in a legal capacity
  • not be employed by the Home Office
  • not have been convicted of an imprisonable offence within the last 10 years—
  • have known the applicant personally for at least 3 years
  • be willing to give details of their knowledge of the applicant
  • confirm that the photograph attached to the application is a true likeness of the applicant
  • agree to advise the Home Office of any reason why the applicant should not be naturalised

It is important to ensure that the declarations made by the referees are less than 6 months old as at the date the application will be received. If this is not the case, the form will be returned to the applicant to be re-declared. This will delay processing.

British citizenship application process

We will complete the relevant application form (Form AN) on your behalf and send it to the relevant Home Office department.

You’ll get a letter confirming your application. It can take up to 4 weeks for you to get the confirmation.

A decision about your application will usually be made within 6 months, although some applications can take longer.

Citizenship Ceremony

You’ll be invited to book a place at a citizenship ceremony if your application is successful.

You’re usually allowed to take 2 guests with you, and you must take your invitation with you when you go to your ceremony.

There is a ceremony fee of £80.

You’ll have to make an oath of allegiance (or you can make an affirmation if you prefer not to swear by God) and a pledge. This means you’ll promise to respect the rights, freedoms and laws of the UK.

You’ll be presented with your certificate of British citizenship and a welcome pack.

How long does it take to get British citizenship?

The application process normally takes up to 6 months but can take longer. You will need to have a citizenship ceremony at your local registry and are required to book this yourself. When you can be fitted in will also impact how long it takes before you are officially a British citizen.

How long it takes to be eligible to apply will depend on the grounds you rely on. You can read more about this in the section Can I apply for British citizenship?’.

UK citizenship for EU nationals

If you have settled status under the EU settlement scheme, then you can normally apply to become a British citizen a minimum of 12 months after your settled status was confirmed.

If you were not eligible for settled status under the EU settlement scheme, then you will need to apply for British citizenship under one of the other available routes, e.g. via your spouse being a British citizen or by first securing indefinite leave to remain. You can read more about this in the section Can I apply for British citizenship?’.
