A Parliamentary research briefing published on 24 August 2026 updated the Home Office’s estimated unit cost for adult naturalisation to £575, replacing the older £324 figure used in earlier comparisons. The standard adult citizenship total remains £1,839 including the £130 ceremony fee.
- The 24 August 2026 briefing confirms the adult naturalisation charge is £1,839 including the ceremony fee.
- The same briefing puts the Home Office’s estimated “unit cost” for processing a naturalisation application at £575.
- The updated cost figure replaces the earlier £324 estimate that had been used in prior comparisons of the fee against processing cost.
- The briefing keeps the focus on the gap between the citizen-facing charge and the administrative cost of handling the application.
- The Institute for Public Policy Research said adult UK citizenship costs £1,709 for naturalisation, published on 9 September 2026.
- The Home Office estimates processing at £324, making the application fee more than five times the administrative cost.
- Successful applicants pay a separate £130 ceremony fee, bringing most adults’ citizenship-stage total to £1,839.
The Institute for Public Policy Research said adult applicants for UK citizenship pay £1,709 for naturalisation, more than five times the Home Office estimate for processing an application. The institute published the comparison on 9 September 2026.

Successful applicants face a separate payment. A mandatory citizenship ceremony costs £130, bringing the usual total to £1,839 for most adults.
The application fee increased from £1,605 to £1,709 on 8 April 2026. The £324 estimate comes from visa fees transparency data last updated on 17 July 2026.
The institute places the fee among the G7’s highest citizenship charges
The institute described the charge as the third highest fee in the G7 for the service. Its comparison uses the application fee against the department’s processing estimate, while the ceremony creates an additional charge after approval.
That distinction separates two totals. The £1,709 figure covers the application, and £1,839 adds the ceremony. The latter is the amount most successful adult applicants usually pay for the citizenship stage.
The estimate comes from the department’s published visa-fees transparency material. The July 17 update supplied the administrative figure used in the comparison.
Settlement and citizenship payments can bring the government total to £5,065
Many applicants must pay for settlement before seeking citizenship. Indefinite Leave to Remain costs £3,226, and combining that payment with the citizenship charges brings government fees to £5,065.
| Charge or cost | Amount |
|---|---|
| Adult citizenship application | £1,709 |
| Mandatory citizenship ceremony | £130 |
| Application plus ceremony | £1,839 |
| Indefinite Leave to Remain | £3,226 |
| Settlement plus citizenship fees | £5,065 |
The £5,065 amount combines settlement with the application and ceremony payments. It is therefore different from £1,839, which covers the application and ceremony but not settlement.
The wider route can also involve separate spending on visas, health surcharges, translations, legal help and passports. Those items sit outside the government-fee total shown above.
The 2025 comparison used a different cost basis
The House of Commons Library recorded a separate comparison for 2025. It put the citizenship charge, including the ceremony, at £1,735, against a £575 unit cost at that time.
Those figures do not match the current comparison on a like-for-like basis. The earlier charge included the ceremony, while the present five-times comparison uses the £1,709 application fee and a £324 processing estimate.
The different bases explain why the older total was higher than the current application fee, even though the current comparison produces a wider gap between charge and estimated cost.
The fee structure also divides the route into stages. Many people pay the settlement fee first, then the naturalisation fee later, before paying the ceremony charge if the application succeeds.
The settlement and adult application fees both changed on 8 April 2026. The ceremony remains a separate £130 payment, leaving the citizenship-stage total at £1,839.
