Apply for British citizenship by naturalisation with expert guidance
Becoming a British citizen is one of the most significant steps you can take, and it deserves the right support. Whether you are looking to apply for British citizenship by naturalisation or through the registration route, Hedgley Immigration is here to guide you through every stage of the process. Our specialist advisers have in-depth knowledge of UK nationality law and will work with you to build a strong, complete application that gives you the best possible chance of success.
What does it mean to become a British citizen?
British citizenship gives you the full and permanent right to live, work, and participate in public life in the United Kingdom. As a British citizen, you can apply for a British passport, vote in all UK elections, and pass your citizenship on to children born outside the UK in many circumstances.
There are two main legal routes to becoming a British citizen: naturalisation and registration. While both result in the same status, they apply to different groups of people and involve different eligibility criteria. Naturalising as a British citizen is the route taken by most adults who have settled in the UK, whereas registration of British citizenship is typically available to children and certain individuals with a historic connection to the UK.
At Hedgley Immigration, we help clients across both routes, ensuring that each application is carefully prepared and submitted correctly the first time.


Who can apply for British citizenship by naturalisation?
To apply for British citizenship by naturalisation, you must meet a set of requirements established under the British Nationality Act 1981. The main criteria are:
- You are aged 18 or over
- You have been lawfully resident in the United Kingdom for at least five years (or three years if you are married to or in a civil partnership with a British citizen)
- You held settled status (indefinite leave to remain or settled status under the EU Settlement Scheme) for at least 12 months before applying, unless you are married to a British citizen
- You have not spent more than 450 days outside the UK during the five-year qualifying period (or 270 days during the three-year period for spouses and civil partners)
- You have not spent more than 90 days outside the UK in the 12 months immediately before your application
- You have passed the Life in the UK test
- You meet the English language requirement, usually by holding a qualification at B1 level or above, or by being a national of a majority English-speaking country
- You are of good character, which means no serious criminal convictions and no history of deception in previous immigration applications
Naturalising as a British citizen requires careful preparation. The qualifying period, the absences calculation, and the good character assessment are all areas where errors or oversights can lead to delays or refusals. Our team at Hedgley Immigration reviews each case thoroughly before submission to ensure everything is in order.
British citizenship by registration: who is eligible?
British citizenship by registration is a separate route available to individuals who have a legal entitlement to citizenship under the British Nationality Act 1981 or subsequent legislation. Unlike naturalisation, registration of British citizenship is often available to those who have not been resident in the UK for the standard qualifying period.
Those who may be eligible for british citizenship registration include:
- Children born in the UK to a parent who was not a British citizen or settled at the time of their birth, but who have since become settled or British
- Children born outside the UK to a British citizen parent who was themselves born overseas (in certain circumstances)
- Adults born in the UK who did not automatically acquire citizenship at birth
- British overseas territories citizens, British nationals (overseas), and British overseas citizens who meet specific residence requirements
- Stateless persons born in the United Kingdom
- Individuals who would have acquired British citizenship automatically but for historical legislative discrimination, including those affected by the Nationality and Borders Act 2022 provisions
The registration of British citizenship route can be complex, particularly for those relying on discretionary registration or legislative changes introduced in recent years. Hedgley Immigration has experience handling a wide range of registration cases, including those involving historical injustices and family connection routes.


What documents do you need to apply?
The documentation required for your application will depend on the specific route you are taking. For those looking to apply for British citizenship by naturalisation, the following documents are typically required:
- Your current valid passport and all previous passports held during the qualifying period
- Your biometric residence permit (BRP) or evidence of settled status under the EU Settlement Scheme
- Evidence of your continuous lawful residence over the qualifying period, such as bank statements, payslips, council tax bills, tenancy agreements, and P60 forms
- Your Life in the UK test pass certificate
- Evidence of your English language qualification, if applicable
- Details of any time spent outside the United Kingdom during the qualifying period
- A police certificate, if you have lived in certain countries during the qualifying period
- Details of any criminal convictions, civil penalties, or immigration enforcement action
For applications via British citizenship by registration, the specific documents will vary depending on the grounds of your application. In all cases, evidence of your identity, nationality, and connection to the UK will be required.
Incomplete or incorrect documentation is one of the most common reasons applications are delayed or returned. At Hedgley Immigration, we provide a personalised document checklist and review everything before submission to minimise the risk of any problems.

Frequently Asked Questions
How long does it take to apply for British citizenship by naturalisation?
The Home Office currently processes most applications to apply for British citizenship by naturalisation within around six months, though processing times can vary. You can pay for a priority service in some circumstances to receive a faster decision. Once your application is approved, you will need to attend a citizenship ceremony, which is typically arranged within three months of approval. Your local council organises the ceremony, and timescales can differ depending on where you live. Hedgley Immigration will keep you informed throughout the process and advise on what to expect at each stage.
What is the difference between naturalisation and registration of British citizenship?
Naturalisation is the route for most adult migrants who have lived and settled lawfully in the UK for the required period and wish to become British citizens. Registration of British citizenship is generally available to those who have a legal entitlement to citizenship based on their birth, parentage, or a historic connection to the UK, regardless of how long they have lived here. Children are also registered rather than naturalised. Both routes result in the same status as a British citizen, but the eligibility criteria, application forms, and documentation requirements differ significantly between them.
Do I need to pass the Life in the UK test to apply for British citizenship by naturalisation?
Yes, passing the Life in the UK test is a mandatory requirement to apply for British citizenship by naturalisation, unless you are exempt. Exemptions apply to applicants who are under 18, aged 65 or over, or who have a long-term physical or mental condition that prevents them from meeting this requirement. The test consists of 24 multiple-choice questions covering British history, values, culture, and institutions. A pass certificate is valid indefinitely and must be included with your naturalisation application. Hedgley Immigration can advise you on preparation materials and approved test centres.
Who qualifies for British citizenship by registration?
British citizenship by registration is available to several categories of people, including children born in the UK who are stateless or whose parents later became British or settled, children born abroad to British citizen parents in certain circumstances, adults born in the UK who did not automatically acquire citizenship, and individuals affected by historical legislative discrimination. The eligibility criteria for british citizenship registration are set out in the British Nationality Act 1981 and subsequent amendments, including the Nationality and Borders Act 2022 and the Nationality (Proof of Patriality) Act. Because the rules are detailed and can be difficult to interpret, it is advisable to seek expert guidance before applying.
How much does it cost to apply for British citizenship by naturalisation?
The current Home Office fee to apply for British citizenship by naturalisation is set by the government and is subject to change. There is also a separate biometric enrolment fee payable when you attend your appointment. If you wish to use a priority service, an additional fee applies. For registration of British citizenship applications, fees vary depending on the grounds of the application and the age of the applicant. Children's registration fees differ from adult fees. Hedgley Immigration will provide you with a full and up-to-date breakdown of all costs, including our professional fees, during your initial consultation.
Can I include my children in my British citizenship application?
Children cannot be included in an adult naturalisation application; they must apply separately through the registration route. However, it is common for parents to submit their own naturalisation application and their children's registration applications at the same time, which can help streamline the process. Hedgley Immigration can advise on the most efficient way to manage applications for the whole family and ensure that each application meets the relevant eligibility requirements.
