What is British naturalisation?

British naturalisation is the legal process of becoming a British citizen if you are not British by birth. As a naturalised British citizen, you will be eligible for a UK passport and have the same rights and privileges as a British person. You will be able to live, work, and access public funds in the UK. You will also be free of immigration control. Being free of immigration control means you can travel into and out of the UK freely for the rest of your life, removing the need for a visa.

According to the naturalisation guidance, there are several ways to become a naturalised British citizen:

You must be 18 years or over

Have held Indefinite Leave to Remain (ILR) for at least 1 year

Have held EU Settled Status under the EU Settlement Scheme (EUSS) for at least 1 year

Are married to or in a civil partnership with a British citizen and have lived in the UK for at least 3 years

British naturalisation requirements

The requirements you will need to meet depend on the type of UK naturalisation application you are making. The naturalisation guidance provided by the Home Office explains the requirements for naturalisation are as follows:

Requirements for naturalisation if you have indefinite leave to remain or EU Settled Status

Under this route, to naturalise as a British national, you must have resided in the UK for at least 5 years and hold one of the following, and have done so for at least one year:

Indefinite Leave to Remain (ILR) in the UK

Settled Status under the EU Settlement Scheme

Indefinite Leave to Enter the UK

Please note, if you are applying based on your marriage, civil partnership, or relationship to a British national, you will not need to meet the additional one-year residence requirement.

In addition, you must also:

be over 18

be able to prove you have been in England, Wales, Scotland, Northern Ireland, the Isle of Man, or the Channel Island 5 years before the date your UK naturalisation application is received by the Home Office. E.g. if your application is received on 05/05/2022, you should have been physically present in the UK on 06/05/2017.

not have been outside the UK for more than 450 days in the 5-year period before applying

not have been outside the UK for more than 90 days in the 12-month period before applying

be able to prove your knowledge of the English language. You can also apply if you have sufficient knowledge of Welsh or Scottish Gaelic

be of sound mind so that you understand the step you are taking

have passed the life in the UK test

intend to continue living in the UK once you become a UK citizen

be of good character

not have breached the immigration rules

Requirements for citizenship if you are married to or the civil partner of a British citizen

The requirements are broadly the same as above, but you only need to have lived in the UK for a minimum of 3 years before you apply. E.g. if your application is received by the Home Office on 05/05/2022, you must have been living in the UK on 06/05/2019.

The rules also state that you must not have been outside of the UK during the 3 year period for more than 270 days in total. This is the absence requirement which is the maximum time you can be outside of the UK when applying for British Citizenship. In addition, you must not have been outside the UK for more than 90 days in the 12 months before you apply for naturalisation.

The ‘good character’ requirement

The good character requirement means that you must:

have shown respect for the rights and freedoms of the UK, observed its laws, and fulfilled your duties and obligations as a resident of the UK

have been honest in the information you provide to the Home Office

have paid any taxes owing to HMRC meet the requirements for criminality.

You will be asked to provide information on any crimes you have been convicted of, including road traffic offenses. Not all offenses will lead to a refusal of your application. This will depend on whether you received a prison sentence, the duration of the sentence, and how long has passed since the end of the sentence. For example, if you received a sentence of up to 1 year, your application is likely to be refused unless 10 years have passed since the end of the sentence.

‘Sound mind’ means that you must have an understanding of the actions you are taking when you apply for naturalisation. The Home Office may decide to ignore this requirement if it would be in the applicant’s best interests for naturalisation to be granted. If you are applying on behalf of a person in this situation, it is important that you provide details of their mental health condition, confirm that you are providing them with care and support, and provide evidence of their care arrangements.

You will need to pass the Life in the UK test which is designed to ensure you have a broad understanding of British history and culture. This will need to be completed at an approved test centre. There is plenty of information available online, and there are several books available that explain how to pass the test. If you are under 18 or over 65, or you have a physical or mental condition, you may be exempt from taking the life in the UK test.

English Language requirement

To gain citizenship through naturalisation, you will need to meet the English language requirements, either by:

Passing a CEFR English qualification at B1, B2, C1, or C2 level

If you are under 18 or over 65, or you have a physical or mental condition, you may be exempt from meeting the English language requirement. You will also not need to meet this requirement if you are from either one of the following countries: Antigua and Barbuda, Australia, The Bahamas, Barbados, Belize, Canada, Dominica, Grenada, Guyana, Jamaica, Malta, New Zealand, St Kitts and Nevis, St Lucia, St Vincent, and the Grenadines, Trinidad, and Tobago, or the USA.

  • The Home Office will tell you which documents you should submit once you have completed your online application.
  • If you are planning to apply to become a naturalised British citizen, it is essential that you provide all of the information and documents required for British naturalisation by the Home Office.

It is important to note that some countries do not allow dual nationality. Therefore, it is recommended that you check if the other country in which you hold citizenship allows dual nationality before applying.
