British Citizenship & Naturalisation Solicitors
Obtaining British citizenship allows you to live and work in the UK permanently, without immigration restrictions. It also gives you the right to apply for a British passport, vote in UK elections, and receive consular assistance when abroad.
British citizenship—often referred to as naturalisation—is a major step, and the application process can be complex. If you are not already a British citizen but want to become one, you must apply through the appropriate legal route.
Our network of experienced immigration solicitors can support you at every stage of your British citizenship application, offering affordable fixed-fee advice tailored to your circumstances.
What Is British Citizenship?
British citizenship gives you:
The permanent right to live and work in the UK
Freedom from immigration time limits
Eligibility for a UK passport
The right to vote in UK elections
Protection and assistance from UK embassies overseas
Applying for citizenship does not automatically give you the right to stay in the UK while your application is being decided. You must already have lawful status, such as:
Indefinite Leave to Remain (ILR)
Settled or pre-settled status under the EU Settlement Scheme
Another form of permanent permission to stay

How to Apply for British Citizenship
You can apply for British citizenship by naturalisation either:
On your own
With the help of a legal representative
The correct application route depends on how you qualify for citizenship, such as residence length, marital status, or parental nationality.
Eligibility Requirements for British Citizenship
To apply for British citizenship, you must generally:
Have lived lawfully in the UK for the required qualifying period
Have been physically present in the UK on the first day of that qualifying period
Be free from immigration time restrictions
Intend to continue living in the UK (unless applying as a spouse/civil partner)
Have passed the Life in the UK Test
Meet the English language requirement
Be of good character
You must also be mentally capable of understanding the responsibilities of British citizenship. Applications can be made on behalf of individuals who lack mental capacity, with supporting medical evidence.
Referees for Your Application
You must provide two referees:
One referee must be a professional (any nationality)
One must be a British passport holder aged 25 or over
Both referees must:
Have known you for at least 3 years
Not be related to you or each other
Not be your solicitor
Not work for the Home Office
Referees with serious criminal convictions in the last 10 years are unlikely to be accepted.
Submitting Your Application
Most applicants apply online. Paper applications (Form AN) are used only in specific locations, such as British Overseas Territories.
You can:
Apply for children under 18
Include eligible family members
The application fee must be paid at the time of submission and is non-refundable if your application is refused.
Biometric Information
After applying, you must provide biometric details, including:
A photograph
Fingerprints (for most applicants aged 5 and over)
You must attend a biometric appointment within 45 days, or your application may be invalidated.
Children under 16 must attend with a parent or guardian.
Processing Times
British citizenship applications usually take around 6 months.
The Home Office may request additional information, which can extend processing times. You must maintain valid immigration status while waiting for a decision.
Citizenship Ceremony
If your application is approved, you will be invited to attend a citizenship ceremony, where you will:
Swear an oath of allegiance
Make a pledge to respect UK laws and values
Receive your naturalisation certificate
Citizenship by Birth in the UK
Being born in the UK does not automatically make you a British citizen.
You are usually British at birth if:
You were born on or after 1 January 1983 and
At least one parent was British or settled in the UK
Children under 18 may already be British if one parent holds British citizenship.
Citizenship Through Marriage or Civil Partnership
Marriage to a British citizen does not automatically grant citizenship.
You may apply by naturalisation if you:
Are 18 or over
Have lived in the UK for at least 3 years
Hold ILR, settled status, or permanent permission to stay
You must also meet language, life in the UK, and good character requirements.
Widows and widowers cannot apply under this route.
Indefinite Leave to Remain or Settled Status
ILR or settled status does not equal British citizenship.
Most applicants must wait 12 months after obtaining ILR or settled status before applying—unless married to a British citizen.
Illegal Entry and Citizenship Applications
If you entered the UK illegally on or after 7 March 2023, you are generally not eligible for British citizenship unless strict exceptions apply.
Applications made in breach of these rules are likely to be refused, and fees are usually non-refundable.
Other Routes to British Citizenship
You may be eligible if:
You have a British parent
You hold another form of British nationality
You are stateless
You previously renounced citizenship
You are a descendant of Chagossians
Special or compassionate circumstances apply
The Windrush Scheme
You may qualify under the Windrush Scheme if you:
Arrived in the UK before 1973 from a Commonwealth country
Are settled but lack documentation
Eligible applicants can apply without paying a fee.
Absences From the UK
Absences are closely reviewed:
5-year route: no more than 450 days
3-year route: no more than 270 days
Final 12 months: no more than 90 days
Discretion may apply in exceptional cases.
Language and Life in the UK Requirements
Unless exempt, you must demonstrate:
English language ability at B1 CEFR or above
Successful completion of the Life in the UK Test
Exemptions may apply for applicants aged 65 or over or those with qualifying medical conditions.
Good Character Requirement
The Home Office will assess:
Criminal convictions
Financial conduct and tax history
Honesty in immigration applications
