Becoming a British citizen is a significant milestone for many individuals who have made the United Kingdom their permanent home. However, before applying for naturalisation, it is important to understand the full costs involved. In 2026, the cost of obtaining British citizenship has increased, making financial planning an essential part of the application process.
This guide explains the UK citizenship costs in 2026, additional expenses applicants should budget for, and factors that may affect the overall price of becoming a British citizen.
How Much Does UK Citizenship Cost in 2026?
The main cost for most applicants is the British citizenship naturalisation fee charged by the Home Office.
As of April 2026, the fee for an adult applying for British citizenship through naturalisation is £1,839. This fee includes the citizenship ceremony fee required upon successful approval of the application.
It is important to note that Home Office fees are subject to change, and applicants should always verify the latest fees before submitting an application.
What Does the British Citizenship Fee Cover?
The British citizenship application fee covers:
- Processing and assessment of the application;
- Background and security checks;
- Administrative costs;
- Decision-making by the Home Office; and
- The citizenship ceremony fee where applicable.
Even if an application is refused, most of the fee is generally non-refundable because the Home Office will have already undertaken the work required to assess the application.

Additional Costs to Consider For British Citizenship Application:
While the naturalisation fee is the largest expense, it is not the only cost applicants may face.
Life in the UK Test:
Most applicants must pass the Life in the UK Test before applying for British citizenship.
The test fee remains £50 per attempt in 2026. Applicants who fail the test must pay the fee again to retake it.
English Language Test:
Applicants who cannot rely on a degree taught in English or a previous accepted English qualification may need to take an approved English language test.
Depending on the provider and location, applicants can expect to pay between £120 and £200 for an approved B1 English language test.
Document Translation Costs:
Any documents not written in English or Welsh must usually be professionally translated.
Translation costs vary depending on:
- The number of documents;
- The length of the documents; and
- The translator’s fees.
Applicants should budget between £30 and several hundred pounds depending on their circumstances.
Legal or Immigration Advice:
Although it is possible to submit a citizenship application without legal representation, many applicants choose to instruct an immigration solicitor or adviser.
Typical professional fees can range from:
- £300–£800 for application checking services;
- £800–£2,000+ for full legal representation; and
- Higher amounts for complex nationality matters.
Professional assistance can be particularly beneficial where applicants have:
- Previous immigration issues;
- Criminal convictions;
- Long absences from the UK;
- Complex residence histories; or
- Questions regarding eligibility.
Cost of a British Passport After Citizenship:
Once citizenship has been granted, many new British citizens apply for their first British passport.
The passport application fee is separate from the citizenship fee and must be paid directly to HM Passport Office.
Applicants should therefore budget for an additional passport application fee after their naturalisation application has been approved.

What Happens If My Citizenship Application Is Refused?
One of the most important points applicants should understand is that citizenship fees are generally non-refundable if the application is refused.
This means applicants could lose the entire application fee if:
- They fail to meet the residence requirements;
- They do not satisfy the good character requirement;
- They submit incorrect information; or
- They fail to provide sufficient supporting evidence.
For this reason, applicants should carefully assess their eligibility before submitting an application.
How to Budget for UK Citizenship in 2026:
For many applicants, the total cost of becoming a British citizen extends beyond the Home Office fee.
A realistic budget may include:
| Expense | Estimated Cost |
| Citizenship Application Fee | £1,839 |
| Life in the UK Test | £50 |
| English Language Test | £120–£200 |
| Document Translations | Variable |
| Legal Advice (optional) | £300–£2,000+ |
| British Passport Application | Additional fee payable |
Depending on individual circumstances, the total cost can easily exceed £2,000.

Conclusion:
