British Citizenship After ILR in 2026 – Requirements, Costs and Timeline
Can You Apply for British Citizenship After Indefinite Leave to Remain?
Yes. After obtaining Indefinite Leave to Remain (ILR), most individuals can apply for British citizenship through naturalisation.
In most cases, you must wait 12 months after being granted ILR before applying. However, if you are married to a British citizen, you may be eligible to apply immediately after receiving ILR.
If you are unsure about your eligibility, speak to our experienced Immigration Solicitors for tailored advice:

British Citizenship Eligibility Requirements in 2026
To apply for British citizenship after ILR, you must meet strict Home Office requirements.
1. Residency Requirement
You must:
- Have lived in the UK for at least 5 years
- Hold ILR for at least 12 months (unless married to a British citizen)
- Not exceed permitted absences from the UK
Excessive absences can delay or prevent approval.
2. Good Character Requirement
Applicants must demonstrate good character. The Home Office will assess:
- Criminal record
- Immigration compliance history
- Financial conduct, including unpaid debts to the government
Any previous immigration breaches should be reviewed carefully before applying.
3. English Language and Life in the UK Test
Most applicants must:
- Pass the Life in the UK Test
- Meet English language requirements
If these were satisfied during your ILR application, you may not need to repeat them.

- Document review
- Decision by the Home Office
- Citizenship ceremony

How Much Does British Citizenship Cost?
The application fee is set by the UK government and may change annually. In addition to the main fee, applicants should budget for:
- Biometric enrolment
- Citizenship ceremony fee
- Legal representation (if required)
Always check the official gov.uk website for the latest fee updates.
Common Reasons British Citizenship Applications Are Refused
Applications may be refused due to:
- Excess absences from the UK
- Failure to meet good character requirements
- Incorrect or incomplete documentation
- Previous immigration breaches
If your ILR status has complications, it is essential to resolve them before applying for naturalisation.
If you are concerned about refusal risks, professional advice can help you prepare a stronger application.
Do You Automatically Become British After ILR?
No. ILR allows you to live and work in the UK without time restrictions, but it does not grant British citizenship.
Citizenship must be applied for separately and involves additional legal requirements.
