British citizenship is more than a legal status—it symbolises full integration into life in the United Kingdom. For individuals who have made the UK their permanent home, naturalisation offers a secure, long-term future with the full rights and responsibilities of a British national. This page explains the eligibility requirements, the naturalisation process, and how to ensure your application is complete and compliant under current Home Office guidance.
What Is Naturalisation?
Naturalisation is the process by which a non-British adult becomes a British citizen. Governed by the British Nationality Act 1981, it allows eligible applicants to apply for citizenship by meeting certain legal, residence, and character requirements.
Applicants may apply:
- In their own right, based on length of residence in the UK and immigration status
- As the spouse or civil partner of a British citizen
A successful application results in the grant of British citizenship, allowing the individual to obtain a British passport and enjoy all the rights of a UK national, including voting and the ability to pass citizenship to children.
Eligibility Criteria
General Naturalisation (Own Right)
To apply for naturalisation independently, you must meet the following core requirements:
- Age: You must be at least 18 years old
- Lawful residence: You must have lived in the UK for at least 5 continuous years before the date of your application
- Settled status: You must hold Indefinite Leave to Remain (ILR) or settled status under the EU Settlement Scheme, and have held that status for at least 12 months
- Time outside the UK: You must not have been absent from the UK for more than:
- 450 days during the 5-year period, and
- 90 days in the 12 months before applying
- Presence in the UK: You must have been physically present in the UK exactly 5 years before the date the Home Office receives your application
- Language & knowledge: You must pass the Life in the UK Test and satisfy the English language requirement
- Good character: You must be of good character (see below)
Naturalisation as a Spouse or Civil Partner of a British Citizen
You may apply under this route if you are married to or in a civil partnership with a British citizen. The requirements differ slightly:
- Residence: You must have lived in the UK for at least 3 continuous years
- Immigration status: You must hold ILR, settled status, or indefinite leave to enter
- Absences: You must not have been absent from the UK for more than:
- 270 days during the 3-year period, and
- 90 days in the 12 months before applying
- Presence in the UK: You must have been in the UK exactly 3 years before your application is received
- Language & knowledge: You must meet the English language and Life in the UK Test requirements
- Good character: As with all routes, you must be of good character
Note: Unlike the general route, the 12-month waiting period after obtaining ILR does not apply if you are applying as a spouse or civil partner of a British citizen.
Understanding the Good Character Requirement
All naturalisation applicants must demonstrate good character. Although the term is not defined in legislation, the Home Office provides detailed guidance on how it is assessed. Relevant factors include:
- Criminal convictions: Both UK and overseas convictions are considered. Certain offences may result in automatic refusal.
- Compliance with immigration law: Overstaying, illegal entry, or failure to comply with visa conditions may affect your application.
- Financial responsibility: Bankruptcy, unpaid taxes, or fraud may be taken into account.
- Honesty and disclosure: All relevant facts, including minor offences (such as traffic penalties), should be disclosed. Failure to do so may be treated as deception.
Each case is assessed on its individual merits. It is strongly recommended to seek legal advice if your circumstances include any issues that may affect your good character assessment.
English Language and Life in the UK Requirements
To naturalise, applicants must prove they have:
- Sufficient knowledge of English, Welsh, or Scottish Gaelic. This is usually demonstrated by passing a minimum of an approved B1-level speaking and listening test, or holding an academic qualification taught in English.
- Passed the Life in the UK Test, which evaluates knowledge of British history, traditions, and values (exempt for certain age groups).
Exemptions:
You may be exempt from these requirements if:
- You are aged 65 or over, or
- You have a long-term physical or mental condition that prevents you from meeting them (with supporting medical evidence)
Application Process (Form AN)
- Complete Form AN online or via paper form (most applicants apply online)
- Prepare and submit your documents, including:
- Passport or travel ID
- ILR or settled status proof
- Proof of residence and absences
- Marriage certificate (if applicable)
- Life in the UK Test and English language evidence
- Pay the application fee (currently £1,735 including the citizenship ceremony)
- Provide biometrics at a UKVCAS appointment
- Wait for a decision (usually within 6 months)
- Attend a citizenship ceremony if approved, where you receive your certificate of naturalisation
