British Citizenship Document Checklist 2026

Updated: 2 August 2026

Applying for British citizenship by naturalisation requires much more than uploading a passport and proof of Indefinite Leave to Remain. Applicants must first identify the correct qualifying route and then provide documents addressing their identity, immigration status, UK residence, absences, English-language ability, Life in the UK test, referees and good character.

This British citizenship document checklist focuses primarily on adult naturalisation applications under Form AN. Different requirements apply to children, people who are already British automatically and applicants using a statutory registration route.

The current official requirements are set out in the Home Office’s Form AN guidance.

British citizenship document checklist at a glance

Most straightforward adult naturalisation applications will require:

• Current passport or travel document
• Previous passports covering the qualifying period
• Biometric Residence Permit or Biometric Residence Card, if issued
• Proof of ILR, settled status or another permanent status
• Complete UK travel and absence history
• Evidence of UK residence where passport records are incomplete
• Life in the UK test reference number
• English-language evidence or evidence of exemption
• Two completed referee declarations
• Recent passport-style photograph for the referee declarations
• Evidence of any change of name
• Marriage or civil-partnership documents when using the three-year spouse route
• Documents addressing any criminal, civil, tax or immigration issues
• Certified translations where relevant
• A covering letter where an explanation or discretion is required

Not every document listed in this guide will be required in every application. The correct checklist depends on the applicant’s personal circumstances.

Check whether you need naturalisation or registration

Before paying the application fee, check whether you:

• Are already a British citizen automatically
• Must apply for naturalisation as an adult
• Qualify to register as a British citizen under a statutory provision
• Are applying for a child under 18
• Qualify through a British parent
• Qualify under a special route for Irish citizens
• Have another form of British nationality
• Qualify under the Windrush Scheme

Children under 18 do not naturalise using Form AN. They normally apply for registration, often using Form MN1, and require a different document checklist.

Use the official British citizenship eligibility service to identify the correct route.

Eligibility requirements before preparing documents

Standard five-year naturalisation route

An adult applying under section 6(1) will normally need to demonstrate that they:

• Are aged 18 or over
• Have lived lawfully in the UK for at least five years
• Were physically present in the UK at the beginning of the qualifying period
• Hold ILR, settled status, indefinite leave to enter or another qualifying permanent status
• Have normally been free from immigration time restrictions for at least 12 months
• Have not normally spent more than 450 days outside the UK during the five-year period
• Have not normally spent more than 90 days outside the UK during the final 12 months
• Meet the English-language requirement
• Have passed the Life in the UK test
• Intend to continue living in the UK or meet an applicable alternative
• Satisfy the good-character requirement

Three-year route for spouses of British citizens

An applicant married to, or in a civil partnership with, a British citizen can normally apply under section 6(2) if they:

• Are aged 18 or over
• Are legally married to, or in a civil partnership with, a British citizen on the application date
• Have lived in the UK for at least three years
• Were physically present in the UK at the beginning of the three-year qualifying period
• Hold ILR, settled status, indefinite leave to enter or another qualifying permanent status on the application date
• Have not normally spent more than 270 days outside the UK during the three-year period
• Have not normally spent more than 90 days outside the UK during the final 12 months
• Meet the English-language requirement
• Have passed the Life in the UK test
• Satisfy the good-character requirement

A spouse of a British citizen does not normally need to hold ILR or settled status for 12 months. They can usually apply as soon as qualifying permanent status has been granted, provided every other requirement is satisfied.

Read the official British-citizen spouse eligibility requirements.

1. Identity documents

Current passport

Provide a complete copy of your current passport, including:

• Personal-information page
• Passport number
• Photograph and signature
• Visa pages
• Entry and exit stamps
• Blank pages if requested by the document-upload system

The name used in the naturalisation application should normally match the name shown in your current passport or official travel document.

Previous passports

Provide previous passports covering the relevant five-year or three-year qualifying period.

Previous passports help establish:

• Travel dates
• UK entry and departure history
• Previous immigration permission
• Changes in personal details
• Residence during the qualifying period

If a previous passport is lost, stolen or unavailable, explain this in a covering letter and provide alternative evidence.

Alternative identity evidence

Depending on the circumstances, additional identity evidence may include:

• National identity card
• Home Office travel document
• Birth certificate
• Photographic driving licence
• Home Office entitlement card
• ARC documentation
• A recent bank, building-society or credit-card statement

The Home Office’s current guidance states that if an applicant was issued a BRP, it should be used in support of the application alongside appropriate identity evidence.

2. BRP, BRC and eVisa documents

Where applicable, provide:

• Biometric Residence Permit
• Biometric Residence Card
• UKVI account details
• eVisa status information
• Share code
• 16-digit Unique Application Number
• Home Office decision letter confirming permanent status

The July 2026 Form AN guidance allows a BRP or BRC to be used for up to 24 months after its printed expiry date, provided the applicant still holds the relevant status. An expired BRP can only be used in this way until the end of 2026.

An expired card does not mean that a person’s underlying ILR has expired. However, the applicant must still establish their current status through the relevant Home Office record.

3. Proof of ILR, settled status or permanent status

An applicant can normally provide one or more of the following:

• eVisa share code showing ILR
• Unique Application Number for the settlement application
• Home Office ILR decision letter
• Passport containing an ILR endorsement
• BRP confirming indefinite leave
• EU Settlement Scheme settled-status decision
• Certificate of entitlement to the right of abode
• Irish passport where relying on status as an Irish citizen
• Other evidence showing freedom from immigration time restrictions

Twelve months after ILR

Applicants using the standard five-year route should normally have held ILR, settled status or another qualifying permanent status for at least 12 months.

Evidence should establish the date permanent status was granted. This may be shown through:

• Home Office decision letter
• eVisa record
• Settled-status email
• BRP issue information
• Unique Application Number linked to the settlement decision

Spouse of a British citizen

Applicants using the three-year spouse route only need to be free from immigration time restrictions on the application date. They do not normally have to wait 12 months after receiving ILR or settled status.

4. Evidence of UK residence

Passports are the primary residence evidence requested by the Home Office. Where passports are missing, incomplete or do not contain entry stamps, alternative evidence may include:

• Employer letters confirming employment dates
• P60s
• Payslips
• Letters from universities, colleges or schools
• Government-department correspondence
• HMRC employment records
• Bank statements demonstrating activity in the UK
• Tenancy documents
• Council Tax documents
• Utility bills
• Evidence of medical appointments where no stronger evidence is available

A doctor’s letter is not normally accepted as the only proof of residence, but it may assist where no other evidence is available and the doctor can confirm regular contact.

P60s, payslips and utility bills are not automatically mandatory for every naturalisation application. They are particularly useful when passport or travel evidence does not clearly establish residence.

5. Travel and absence schedule

Prepare a complete chronological list of every journey outside the UK during:

• The five years before a standard naturalisation application; or
• The three years before an application as the spouse or civil partner of a British citizen.

The schedule should include:

Information	Details required
Departure date	Date you left the UK
Return date	Date you returned to the UK
Destination	Country or countries visited
Reason	Holiday, work, study, family visit or emergency
Whole days absent	Excluding departure and return dates
Evidence	Passport stamp, ticket or other record

The Home Office counts only whole days outside the UK. The departure and return dates are not normally counted.

Normal absence limits

Application route	Overall limit	Final 12-month limit
Standard five-year route	450 days	90 days
British-citizen spouse route	270 days	90 days

The Home Office has discretion to overlook excess absences in some circumstances. However, discretion is not automatic and must be supported by a proper explanation and evidence.

The Home Office advises applicants to provide the most accurate travel information available. It checks its own records, so there is normally no need to request Home Office entry and exit records before applying.

6. Evidence of physical presence on the qualifying date

An applicant must have been physically present in the UK at the beginning of the relevant qualifying period.

The Form AN calculation generally requires the applicant to:

1. Take the proposed application date.
2. Go back five years, or three years for a British-citizen spouse.
3. Add one day to identify the first day of the statutory qualifying period.
4. Confirm that they were physically present in the UK on that date.

For example, for an application submitted on 1 September 2026 under the five-year route, the qualifying-period start date would generally be 2 September 2021.

Evidence may include:

• Passport
• Boarding pass
• Bank transaction in the UK
• Employer attendance record
• Payslip
• Tenancy evidence
• Educational attendance record
• Other reliable evidence showing physical presence

Applying on the wrong date can lead to refusal or significant delay.

7. Life in the UK test evidence

Provide the Life in the UK test reference number.

If the test was passed:

• On or after 1 October 2019, enter the test reference number in the application.
• Before 1 October 2019, provide the original Home Office confirmation letter where applicable.

A person who passed the Life in the UK test for ILR can normally rely on the same pass for naturalisation.

The current test fee is £50. Applicants should use the official Life in the UK test booking service.

8. English-language documents

The English-language requirement is separate from the Life in the UK requirement. Unless exempt, the applicant must provide evidence through one accepted method.

Approved B1 English test

Provide the unique reference number for a Home Office-approved Secure English Language Test at B1 CEFR or above.

A test must normally:

• Be on the approved SELT list
• Have been taken at an approved centre
• Meet the required speaking and listening level
• Be valid on the application date

If the same B1 qualification was accepted for an ILR application, the applicant can normally rely on it again for naturalisation without taking another test.

UK degree

Provide the degree certificate for a UK:

• Bachelor’s degree
• Master’s degree
• PhD
• Qualifying postgraduate or graduate diploma

The qualification must meet the requirements described in the Form AN guidance.

Overseas degree

Depending on where the qualification was taught, provide:

• Degree certificate
• Ecctis Academic Qualification Level Statement
• Ecctis English Language Proficiency Statement, where required

Majority English-speaking nationality

Applicants from a recognised majority English-speaking country can normally provide their passport as evidence of nationality. They must still meet the Life in the UK requirement unless exempt.

Exemption

Applicants aged 65 or over are normally exempt from the English-language and Life in the UK requirements.

A person with a long-term physical or mental condition that permanently prevents them from meeting the requirements may request an exemption. This normally requires:

• The published medical waiver form
• Detailed medical evidence
• Completion by an appropriate registered medical practitioner

Temporary illness, illiteracy or long residence in the UK does not automatically establish an exemption.

9. Referee documents

Every adult naturalisation application requires two suitable referees.

First referee

The first referee:

• Can be of any nationality
• Must be a professional person
• Must have known the applicant personally for at least three years

Examples can include a minister of religion, civil servant, accountant or member of a recognised professional body.

Second referee

The second referee must:

• Hold a British citizen passport
• Be a professional person or aged over 25
• Have known the applicant personally for at least three years

Both referees must not be:

• Related to the applicant
• Related to each other
• The adviser or representative handling the application
• Employed by the Home Office
• Disqualified by relevant criminal convictions

Prepare the following information for each referee:

• Full name
• Date of birth
• Home address
• Previous address where relevant
• Telephone number
• Email address
• Profession
• British passport number where applicable
• Explanation of how they know the applicant
• Signed referee declaration

Follow the online application instructions for downloading, signing and uploading the referee declaration pages. A recent passport-style photograph should be attached as instructed, with the applicant’s name and date of birth recorded where required.

10. Additional documents for a British-citizen spouse

An applicant relying on section 6(2) must provide:

• Marriage certificate or civil-partnership certificate
• Spouse’s or civil partner’s current British passport; or
• Spouse’s naturalisation or registration certificate proving British citizenship

The applicant must remain legally married to, or in a civil partnership with, the British citizen on the application date.

Being an unmarried partner of a British citizen is not sufficient for the three-year naturalisation route.

Joint bank statements, utility bills and relationship photographs are not ordinarily mandatory merely to prove a subsisting marriage, although the Home Office can request additional evidence if circumstances require clarification.

11. Name-change documents

Where the applicant has changed their name, provide the relevant link between all identities, such as:

• Marriage certificate
• Civil-partnership certificate
• Deed poll
• Statutory declaration
• Gender Recognition Certificate
• Medical evidence supporting a permanent change of gender
• Previous and current passports
• Updated national identity document

Names and personal details should be consistent across the application, passport, eVisa and supporting documents. Inconsistencies should be explained before submission.

12. Good-character documents

Good character is considered separately from residence and immigration status. Applicants must disclose relevant matters even if they believe the issue is old, minor, spent or already known to the Home Office.

Depending on the circumstances, provide:

• Court judgment or sentencing documents
• Police or prosecution correspondence
• Evidence of cautions, warnings or reprimands
• Details of fixed penalties where relevant
• DVLA driving-record summary
• Evidence concerning pending charges or investigations
• Civil judgments or civil-penalty documents
• Bankruptcy and discharge documents
• HMRC correspondence
• Council Tax repayment evidence
• Evidence relating to public-fund overpayments
• Evidence concerning an unpaid NHS debt
• Documents explaining an immigration breach
• Evidence addressing any allegation of deception
• A detailed covering letter with relevant mitigation

The Home Office may check information with the police, HMRC and other government bodies.

If a person is liable for income tax but does not pay through PAYE, the Form AN guidance requires evidence that their HMRC obligations have been discharged, normally through a Self-Assessment Statement of Account.

Never conceal an issue because it does not appear on a basic criminal-record certificate. Full and accurate disclosure is essential.

13. Evidence for excessive absences or discretion

Where an applicant exceeds a normal residence requirement, provide:

• Detailed explanation of every relevant absence
• Employer letters
• Evidence that travel was required for UK-based employment
• Crown-service documents
• Medical records
• Evidence of compassionate circumstances
• Evidence of pandemic-related travel restrictions
• Proof of an established home in the UK
• Evidence of immediate family living in the UK
• UK employment or business evidence
• Evidence showing a substantial connection with the UK
• A properly structured request for discretion

Providing evidence does not guarantee that discretion will be exercised.

14. Tax and self-employment documents

Employed applicants do not automatically need to upload every payslip or tax document. However, the application requires accurate employment information and the Home Office can check HMRC records.

Self-employed applicants or people who do not pay tax through PAYE should consider providing:

• Self-Assessment Statement of Account
• Recent tax calculation
• Evidence that outstanding tax has been paid
• HMRC payment arrangement, if applicable
• Accountant’s letter where it clarifies the position

Any discrepancy between information given to HMRC and the information in the citizenship application should be resolved or properly explained.

15. Certified translations

Where a supporting document is not in English or Welsh, provide a complete certified translation containing:

• Confirmation that it is a true and accurate translation
• Translation date
• Translator’s full name
• Translator’s signature
• Translator or translation company’s contact details
• Relevant professional credentials

Upload both the original-language document and its translation.

16. Covering letter

A covering letter is not mandatory in every case, but it can help organise the application.

A useful covering letter may include:

• Applicant’s full name and application route
• Immigration-status history
• Date ILR or settled status was granted
• Residence and absence summary
• Explanation of missing passports
• Explanation of name differences
• List of supporting documents
• English-language basis
• Referee confirmation
• Relevant good-character disclosures
• Request for discretion, where necessary
• Explanation of any inconsistency

The covering letter must remain accurate and should not make unsupported claims.

Uploading British citizenship documents

For an online application:

• Upload clear and complete colour scans
• Include all relevant pages
• Ensure documents are readable
• Use logical file names
• Upload the correct document under the correct category
• Include both original documents and translations
• Retain original documents in case they are requested
• Do not alter, crop or digitally manipulate documents
• Check that every document relates to the correct applicant

The Home Office states that documents uploaded with previous immigration applications remain on its records. However, applicants should still upload the current documents specifically requested by the naturalisation application and the evidence on which they rely.

British citizenship application fee in 2026

From 8 April 2026, the total adult naturalisation cost is:

• Naturalisation application fee: £1,709
• Citizenship ceremony fee: £130
• Total Home Office fee: £1,839

Biometric enrolment does not carry an additional Home Office fee.

The total is confirmed on the official British citizenship eligibility and fees page.

The fee is substantial and is not normally fully refunded if an application is refused. Eligibility should therefore be checked before payment.

Processing time and priority service

A standard naturalisation application will usually be decided within six months, although complex applications can take longer.

A citizenship priority service was introduced in 2026. Where offered:

• Additional fee: £500
• Target decision time: 30 working days
• Availability: Subject to eligibility and availability
• Complex checks can cause a longer decision time

Super priority service is not available for citizenship applications.

Check the current GOV.UK priority-service guidance before applying.

What happens after submission?

The usual process is:

1. Submit the online application and pay the fee.
2. Upload supporting documents.
3. Follow instructions for biometric enrolment.
4. Provide fingerprints and a photograph where required.
5. Respond promptly if the Home Office requests further information.
6. Notify the Home Office about material changes in circumstances.
7. Receive the decision.
8. If approved, book and attend a citizenship ceremony.
9. Receive the naturalisation certificate at the ceremony.
10. Apply for a British passport or certificate of entitlement for travel.

A citizenship application does not extend immigration permission. The applicant must continue to hold valid immigration status until citizenship is acquired at the ceremony.

Citizenship ceremony

An adult does not normally become a British citizen merely when the approval email is received. Citizenship is acquired when the applicant attends the ceremony, takes the oath or affirmation and makes the pledge.

The ceremony must normally be attended within three months of receiving the invitation. The standard ceremony cost is included in the application fee, although a private ceremony may cost more.

After the ceremony, follow the current Home Office instructions concerning any BRP or BRC. The latest Form AN guidance states that it should be destroyed after the ceremony.

A naturalisation certificate, BRP or eVisa cannot ordinarily be used as a British travel document. The new citizen should obtain a British passport or a certificate of entitlement to the right of abode before travelling as a British citizen.

Common document mistakes

Common problems include:

• Applying under the wrong citizenship route
• Applying before completing 12 months with ILR
• Forgetting that the spouse route requires a legal marriage or civil partnership
• Applying while outside the UK on the qualifying-period start date
• Providing incomplete travel dates
• Exceeding the absence limit without requesting discretion
• Using an unapproved English test
• Omitting the English-test or Life in the UK reference number
• Selecting referees who do not meet the requirements
• Using the adviser handling the application as a referee
• Failing to provide the British spouse’s citizenship evidence
• Providing inconsistent names across documents
• Failing to disclose criminal, tax, civil or immigration matters
• Uploading unreadable or incomplete documents
• Failing to provide translations
• Assuming ILR automatically guarantees citizenship

Naturalisation is discretionary. Holding ILR does not create an automatic entitlement to British citizenship.

Frequently asked questions

Do I need to provide bank statements?

Bank statements are not automatically required in every naturalisation application. They may be useful as residence evidence, identity evidence or to explain a particular issue.

Do I need P60s for all five years?

Not necessarily. Passports are the primary evidence of residence. P60s and employer documents are particularly useful where passports are missing or do not show complete travel history.

Can I apply immediately after receiving ILR?

Usually not under the standard five-year route. You normally need to hold ILR or settled status for 12 months. A person married to or in a civil partnership with a British citizen can normally apply immediately after obtaining ILR if all other requirements are satisfied.

Can I reuse the English test used for ILR?

If a qualifying B1 English test was accepted for your successful ILR application, it can normally be relied upon again for naturalisation.

Does the Life in the UK test expire?

A genuine Life in the UK pass can normally be reused. Provide the relevant test reference number or historic confirmation letter.

Can my immigration adviser act as a referee?

No. An adviser or representative handling the citizenship application cannot act as the applicant’s referee.

Can I travel while my citizenship application is pending?

The current Form AN guidance allows travel while the application is pending, provided the applicant has a valid passport and valid immigration status. The applicant must still complete biometrics when required, remain contactable and attend the citizenship ceremony if approved.

Does a citizenship application extend my visa?

No. A citizenship application does not grant or extend immigration permission. Valid permission must be maintained until citizenship is acquired at the ceremony.

Can children be included in an adult application?

Children require separate registration applications and are not automatically included in a parent’s naturalisation application.

Is approval guaranteed if all documents are provided?

No. Supporting documents help demonstrate eligibility, but naturalisation remains a discretionary decision and no adviser can guarantee approval.
