Naturalisation as a British citizen

Naturalisation grants foreign nationals British citizenship, enabling them to hold a British passport, vote, and reside in the UK without immigration restrictions. It is the final step for many after years of residence and settlement.

Since October 2025, the Home Office has adopted the new Part Suitability framework for assessing applicants’ immigration history and conduct, aligning good character checks across visa, settlement, and citizenship routes.

Eligibility requirements

Applicants must usually:

• Have held indefinite leave to remain (ILR) or settled status for at least 12 months.
• Have lived in the UK for 5 years (or 3 years if married to a British citizen).
• Meet the good character requirement.
• Pass the Life in the UK test.
• Meet the English language requirement.
• Not have excessive absences from the UK.

Application process

• Step 1 – Confirm eligibility and gather evidence of residence, status, and identity.
   
• Step 2 – Complete the online application and pay the relevant fee.
   
• Step 3 – Upload supporting documents and attend a biometric appointment.
   
• Step 4 – Attend a citizenship ceremony if approved.

Common issues

Applications may be refused if there are gaps in residence, excessive absences, or issues with good character such as criminal convictions or unpaid taxes.

Following the 2025 reforms, applicants can also be refused where previous immigration breaches are identified under the new suitability rules, making early legal advice more important.
