British citizenship represents an important step in the life of immigrants who have settled in Britain. Before filing your application for citizenship, there are some things that you should know in order to be sure that you can become a citizen of the UK.
If you are wondering how to apply for British citizenship, our team at Intime Immigration Solicitors can help you understand the requirements and navigate the process with greater confidence.
Are You Eligible for British Citizenship?
UK citizenship eligibility is based on your immigration status, residency, and personal circumstances. The process of naturalisation is common for adults, but registration could be an option for some people.
Generally, applicants for naturalisation must:
- Be aged 18 or over.
- Meet the applicable UK residence requirements.
- Hold Indefinite Leave to Remain (ILR) or settled status.
- Meet the good character requirement.
- Demonstrate the required knowledge of English, Welsh or Scottish Gaelic, unless exempt.
- Pass the Life in the UK Test, unless exempt.
Generally, an individual would require five years’ residence in the UK, and he or she should have been a holder of ILR or settlement for not less than one year. An eligible spouse of a British citizen may apply under other residency requirements.
In addition, the applicant will be required to meet the absence requirements and be physically present in the UK at the commencement of the qualifying period.
Naturalisation or Registration: Which Route Applies to You?
Understanding the difference between naturalisation and registration is an important part of the British citizenship application process.
Naturalisation: This is the main route for eligible adults who are not already British citizens. Applicants must meet the applicable residence, immigration status and other statutory requirements.
Registration: This route applies to specific categories of adults and children under British nationality law. For example, certain children born in the UK may qualify to register if a parent subsequently obtains settled status.
The correct route depends on your circumstances. Choosing the wrong application or misunderstanding your eligibility could lead to unnecessary costs and delays.
Your British Citizenship Document Checklist:
Preparing your British citizenship documents before submitting your application can help you avoid missing information.
Depending on your circumstances, you may need:
- A valid passport or other accepted identity evidence.
- Proof of ILR or settled status.
- Details of your UK residence and absences.
- Evidence of English-language proficiency, where required.
- Your Life in the UK Test reference number.
- Details of two eligible referees.
- Supporting evidence relating to name changes or other relevant circumstances.
Additional evidence may be necessary if your immigration history is complicated or your circumstances require further explanation.
At Intime Immigration Solicitors, we can help you identify the relevant documents and review your application before submission.
How to Apply: From Online Form to Citizenship Ceremony:
Once you have established your eligibility and prepared your evidence, the next stages are relatively straightforward.
1. Complete the application. Submit the appropriate online form through the official UK government website. Adults applying for naturalisation generally use Form AN.
2. Pay the application fee. Check the applicable fee before submitting your application. The amount depends on the route you choose.
3. Attend your biometric appointment. Follow the instructions provided for submitting your fingerprints and photograph.
4. Wait for the decision. The Home Office may contact you if further information or documents are required.
5. Attend your citizenship ceremony. If your application is approved, you will generally need to attend a ceremony to make the required oath or affirmation and receive your certificate.
Following each stage carefully can help you avoid preventable complications.
Understanding British Citizenship Fees and Processing Times:
British citizenship fees vary according to the application route. As of October 2026, adult naturalisation costs £1,839, including the citizenship ceremony fee. Registration fees differ depending on the applicant’s circumstances.
If you are applying for a child, the requirements and costs may be different.

The citizenship application processing time is generally around six months, although some applications take longer. Processing times depend on individual circumstances and any additional checks required.
Always verify the latest fees and requirements before applying, as immigration rules can change.
