Complete Checklist: All the Documents for British Citizenship in 2026

17 Jul Complete Checklist: All the Documents for British Citizenship in 2026

Every year, thousands of British citizenship applications are refused or delayed for one reason alone: wrong, incomplete or incorrectly formatted documentation. The fee (£1,735, non-refundable) does not come back, and recovering from a refusal is not easy. That is why it is worth investing time in a document checklist before you even open Form AN.

Core Documents Required from All Applicants

• Current valid passport — all pages, including those with entry/exit stamps
• Proof of Settled Status or ILR: UKVI share code (Settled Status) or eVisa (ILR). Old BRPs expired on 31 December 2024
• Life in the UK Test pass certificate (reference number goes on the form)
• English language certificate from a UKVI-recognised provider (B1 CEFR level — potentially B2 from April 2026)
• Proof of continuous residence in the UK for the required period (5 years for standard naturalisation, 3 for spouse of British citizen)
• Detailed list of all absences from the UK during the qualifying period
• Signed declarations from two referees: one must be a British citizen, both must have known you for at least 3 years and hold a recognised professional position
• Completed Form AN and proof of fee payment

Proof of Residence Accepted by the Home Office

To document continuous residence, you can submit a combination of the following documents covering the full required period:

• Payslips or P60 (annual tax summary)
• Bank statements showing regular activity
• Utility bills (electricity, gas, water)
• NHS, GP or dental correspondence
• Tenancy agreement or mortgage statement
• Correspondence from public authorities or educational institutions

Documents must cover the entire period — not just the last 12 months, but all 5 years (or 3 for the spouse route).

Additional Documents for Those Applying as Spouse of a British Citizen

• British spouse’s passport or naturalisation certificate
• Marriage or civil partnership certificate

IMPORTANT: if the marriage took place abroad and the certificate is not in English, it must be translated into English by a certified professional translator.

Which Documents Need to Be Translated into English

The Home Office requires all non-English documents to be accompanied by an English translation. The most common ones that Italians (and others) need translated include:

• Birth certificate — if Italian or issued in another language
• Marriage certificate — if celebrated in Italy or a non-English-speaking country
• Criminal record certificate from the country of origin (e.g. Italian Casellario Giudiziale)
• Academic diplomas or certificates — if issued in a foreign language
• Divorce decree — if issued abroad
• Name change documents — if drawn up in a foreign language

IMPORTANT: Translations for the Home Office do not need to be ‘sworn’ in the Italian sense (court-certified). They must be produced by a professional translator who certifies in writing their competence and the accuracy of the translation. This is exactly the format we use at Words at Hand — certified, signed, and with full translator details.

How Long Does the Home Office Take to Decide?

Standard processing times for naturalisation are approximately 6 months. Well-prepared, complete applications can be processed in 3-4 months. There is currently no priority service available for naturalisation.
