British Citizenship by Naturalisation
check your eligibility before you apply
A British citizenship application by naturalisation should be
prepared around the correct residence basis, settled status,
absences, exact physical presence, English, Life in the UK
and good-character requirements.
Status dates, residence, absences, referee details and supporting documents should form one consistent application.
Route Overview
British citizenship by naturalisation
residence, settled status and application timing
British citizenship by naturalisation may be available to an
eligible adult who meets the applicable status, residence,
knowledge and good-character requirements.
Under the usual naturalisation route, an applicant generally needs five years of UK residence and normally must have held indefinite leave to remain or settled status for at least twelve months. A spouse or civil partner of a British citizen follows a different three-year residence basis and may apply as soon as settled status is held.
The application date must also be checked carefully because the applicant normally needs to have been physically present in the UK exactly five years before applying, or three years before applying under the British-spouse route.
Status dates, residence, travel, referee details and declarations should agree across the application.
Route Snapshot
Core areas to establish
These areas provide an initial overview. The detailed assessment depends on the naturalisation basis, settled status, residence period, absences, good character and supporting records.
01
Settled immigration status
The applicant should normally hold indefinite leave to remain, settled status or another accepted form of freedom from immigration time restrictions.
02
Required residence period
The standard basis normally uses five years of residence, while a spouse or civil partner of a British citizen normally relies on a three-year residence period.
03
Absences and physical presence
Travel dates should be recorded carefully, including whether the applicant was physically present in the UK on the exact date at the start of the relevant three- or five-year period.
04
Knowledge and good character
English-language evidence, the Life in the UK Test, good-character declarations and any relevant immigration, criminal or financial history should be addressed.
Important Route Check
Naturalisation or registration?
Many adults apply for citizenship by naturalisation. Children and people with a specific entitlement under nationality law may instead need a registration application.
The correct nationality route should be identified before applying because eligibility, forms, evidence and the legal basis can differ between naturalisation and registration.
British citizenship eligibility
for naturalisation applications
British citizenship eligibility can depend on age, freedom
from immigration time restrictions, residence, absences,
exact physical presence, English, Life in the UK and good
character. Under the standard five-year route, the intention
to continue living in the UK should also be considered.
01
Age and settled status
The applicant must be an adult and normally hold indefinite leave to remain, settled status or another accepted status without an immigration time limit.
Confirm status and the naturalisation basis
02
Residence period and application date
The applicant should meet the applicable five-year or British-spouse three-year residence basis and choose an application date that satisfies the exact physical-presence rule.
Map the complete residence period
03
Absences and immigration compliance
All travel should be listed accurately and checked against the applicable absence limits. Immigration compliance during the relevant period should also be reviewed.
Review travel and immigration history
04
Knowledge and good character
The applicant should provide accepted English and Life in the UK evidence and disclose information relevant to the good-character assessment.
Review declarations and supporting evidence
Main Requirements

The assessment also includes settled status, absences, physical presence, immigration compliance, English, Life in the UK and good character.
01
Settled status, timing and future residence
Confirm the status relied on, whether the usual twelve-month
settled-status period applies and whether the standard or
British-spouse residence basis is being used. Under the
standard naturalisation route, the intention to continue
living in the UK should also be addressed.
Review
Status held, grant date and citizenship basis
02
Residence and physical presence
The residence period, exact qualifying-date presence and every relevant absence should be recorded and checked before the application date is fixed.
Review
Addresses, travel dates and absence totals
03
Immigration compliance and good character
The applicant should review immigration compliance and disclose criminal, civil, financial, tax or other information that may be relevant to the good-character assessment.

Citizenship applications are assessed individually. Children are normally considered under registration provisions rather than included within an adult naturalisation application.
Supporting Evidence

British citizenship application

documents consistent.

Approval and citizenship are separate stages
An adult naturalisation applicant normally becomes a British citizen only after attending the citizenship ceremony and making the required oath or affirmation and pledge.
Common Questions
British citizenship
frequently asked questions
These answers provide a general introduction. The correct position will depend on settled status, residence, absences, the application date, knowledge requirements and personal history.
Individual Circumstances
Need a more specific review?
Prepare a summary of settled status, UK residence, travel, English and Life in the UK evidence, referees and any relevant good-character matters.
No. Indefinite leave to remain or settled status can provide an important basis for naturalisation, but the applicant must still make a separate citizenship application and satisfy all applicable requirements.
Under the usual five-year naturalisation basis, applicants
normally wait twelve months after becoming settled. A spouse
or civil partner of a British citizen may apply as soon as
qualifying settled status is held if the three-year residence
requirements are met. See the
GOV.UK naturalisation eligibility guidance
and the
British-spouse citizenship guidance
.
The applicant normally needs to have been physically present in the UK exactly five years before the application date, or exactly three years before applying as the spouse or civil partner of a British citizen.
Yes. All departures and returns should be listed accurately and checked against the absence rules. The Home Office may consider discretion in some circumstances, but this should not be assumed.
Many adult naturalisation applicants must satisfy the
knowledge-of-language requirement and pass the Life in the UK
Test. Accepted evidence and exemptions depend on the
applicant's circumstances. GOV.UK explains the accepted
English-language evidence for citizenship
.
Children are not added to an adult naturalisation application. A separate registration application is normally required, and the correct legal basis depends on the child’s birth, parents and immigration circumstances.
GOV.UK currently lists the adult naturalisation
cost as £1,839, consisting of the application fee
and citizenship ceremony fee. A standard decision
is usually made within six months. Eligible
applicants applying from within the UK can also
use the citizenship priority service for an
additional fee, although complex cases can take
longer. Check the
current GOV.UK citizenship fees and processing information
before applying.
Review Your Circumstances
Prepare your British citizenship application with
a clearer understanding of naturalisation
