How Much Does Citizenship Cost in the UK? A Detailed Guide

Becoming a British citizen is a significant step for many people who wish to make the UK their permanent home. The process of gaining British citizenship involves several requirements, including legal applications, documentation, and fees. One of the key considerations for those seeking citizenship is the cost involved. In this detailed guide, we will explore the cost of British citizenship for various routes, including the Naturalisation process, the fees for children, and the costs associated with dual nationality.

Types of British Citizenship and Their Associated Costs

The cost of citizenship in the UK depends on the type of application you are making. The most common routes are through Naturalisation (for adults) or Registration (for children), but each process comes with its own set of fees. Below is a breakdown of these processes.

1. Naturalisation as a British Citizen

Naturalisation is the process through which a non-citizen adult becomes a British citizen. To qualify for Naturalisation, applicants must have lived in the UK for a certain period, typically 5 years (or 3 years if married to a British citizen), and meet other residency requirements.

• Cost of Naturalisation: As of 2025, the application fee for Naturalisation as a British citizen is £1,330. This is the standard cost, and it must be paid at the time of application.

• Additional Costs: While the Naturalisation application fee is a significant cost, applicants should also budget for other potential fees and costs, including:

  • Life in the UK Test: A mandatory test for most applicants who wish to become citizens. The cost of the test is £50.
  • English Language Proficiency Test: If required, applicants must provide proof of English proficiency. The cost for this varies depending on the provider but typically ranges from £150 to £200.
  • Biometrics Appointment: You will need to attend an appointment to provide fingerprints and a photograph. The cost for biometrics is £19.20.

2. Children’s British Citizenship (Registration)

Children under the age of 18 can apply for British citizenship through the Registration process. This is generally easier and less costly than the Naturalisation process. The registration process applies to children born in the UK or those who have a parent who is a British citizen.

• Cost of Registration for Children: The fee for registering a child as a British citizen is £1,012 as of 2025. This fee applies to children who are not automatically British citizens at birth but qualify for British citizenship through their parents’ status or residency history.

• Additional Costs:

  • Similar to adult applicants, children may also need to attend a biometrics appointment, which costs £19.20.

3. Dual Nationality and Fees

The UK allows dual nationality, meaning you can hold British citizenship along with citizenship from another country. If you already have another citizenship and wish to apply for British citizenship, the costs are similar to those for a first-time applicant.

• Dual Nationality: If you are seeking dual nationality (keeping your original citizenship while becoming a British citizen), the application costs are the same as the regular Naturalisation process. However, you should be aware of the costs and requirements of the other country’s immigration or nationality process. Some countries do not allow dual nationality, and you may need to renounce your original nationality.

Other Associated Costs and Factors

Beyond the application fees, there are several other potential costs that applicants should consider when applying for British citizenship.

1. Legal and Advisory Fees

Some individuals may prefer to hire an immigration lawyer or advisor to guide them through the citizenship process, especially if they have a complex immigration history or require help with document submission.

• Cost of Legal Assistance: The cost of legal advice and services can vary widely, depending on the complexity of your case. On average, you can expect to pay between £500 and £2,000 for assistance with your citizenship application. Lawyers often charge an hourly rate, and it is advisable to get an estimate upfront.

2. Application Processing Time and Delays

The processing time for British citizenship applications can take several months, often 6 months or more. During this time, it is important to keep in mind that you may need to pay for documents, tests, and other related services. Moreover, the Home Office may require additional information, which could delay the process and lead to additional costs.

3. Passport Fees for New British Citizens

Once you are granted British citizenship, you will want to apply for a British passport. The cost of obtaining a passport after you’ve been naturalised is:

• Adult Passport (first passport): £93 (standard 34-page passport).
• Child Passport: £49 (for children under 16 years old).

If you need your passport urgently, there is an option for fast-track services, which may incur an additional fee.

4. Renunciation of Original Citizenship

If you are renouncing your original citizenship to apply for British citizenship, the cost of renunciation varies by country. Some countries, like the United States, do not require a formal renunciation fee, while others might charge a fee for renouncing citizenship.

It’s important to research the requirements of your original country’s laws regarding renunciation and dual nationality.

Conclusion

The cost of obtaining British citizenship for UK residents can vary widely depending on the route you take, your specific situation, and additional services you may require.

Here’s a quick summary of the main costs involved:

• Naturalisation as a British Citizen: £1,330 (application fee) + £50 (Life in the UK Test) + £150–£200 (English proficiency test, if applicable) + £19.20 (biometrics fee).
• Registration for Children: £1,012 (application fee) + £19.20 (biometrics fee).
• Legal Assistance (optional): £500–£2,000 depending on the complexity of your case.
• Passport Fees: £93 for an adult, £49 for a child.

Before applying, be sure to check the official UK government website for any changes to fees, as immigration policies and costs are subject to change. Additionally, be prepared for any extra costs related to documents, tests, and legal services if necessary.
