Naturalisation is the most common route for foreign nationals to become British citizens. If you were born outside the UK and do not have a British parent, but currently hold Indefinite Leave to Remain (ILR) or EU Settled Status, you may be eligible to apply.
At HM & Co. Solicitors, our dedicated naturalisation lawyers in London are on hand to guide you through each stage of the process — from eligibility assessment through to submission and final approval.
Once naturalised, you will be granted the same legal rights as any other British citizen. This includes:
The right to apply for a British passport
Full freedom to live, work, and study in the UK
Access to public services and benefits
The right to vote in elections and stand for public office
The ability to sponsor family members for UK immigration
Please note: naturalisation is not the same as applying for a British passport. You must first complete your naturalisation and attend a citizenship ceremony before being eligible to apply for a passport.
For most applicants, you will need to meet the following criteria:
Hold Indefinite Leave to Remain (ILR) or EU Settled Status for at least 12 months
Lawful residence in the UK for at least 5 years before the date of application
No more than 450 days of absence from the UK in that 5-year period
No more than 90 days outside the UK in the final 12 months before applying
Pass the Life in the UK Test
Meet the English language requirement
Be of good character, which includes a clean immigration and criminal record
If you are applying as the spouse of a British citizen, the rules differ slightly and the qualifying period is reduced to 3 years. Our team can advise you on the exact evidence required for your personal circumstances.
If you are an EEA national or the family member of one, you may still be eligible to apply under slightly modified criteria. Our solicitors are highly experienced in handling such applications, ensuring you understand and meet the correct requirements.

Naturalisation is the legal process through which foreign nationals become British citizens. It is the most common route for migrants who have been granted Indefinite Leave to Remain (ILR) to obtain full British nationality and the rights that come with it, including the ability to hold a British passport.
To apply for naturalisation, you must first hold Indefinite Leave to Remain (or Settled Status under the EU Settlement Scheme). You will typically be required to:
Hold ILR for at least 12 months
Prove continuous residence in the UK for at least 5 years
Pass the Life in the UK Test
Meet the English language requirements
Demonstrate that you are of good character
Our team can assess your eligibility and help prepare a complete application on your behalf.
There are several reasons the Home Office may refuse a naturalisation application, including:
A history of criminal convictions or bad character
Spending excessive time outside the UK in the qualifying period
Incomplete or incorrect applications
Failure to meet the residency or English language criteria
HM & Co. Solicitors can review any concerns you may have and advise on your likelihood of success before submitting your application.
The Home Office imposes limits on time spent abroad in the qualifying period. However, if you’ve exceeded these limits but maintain strong personal, family, or professional ties to the UK, discretion may be applied. Our legal team specialises in presenting these types of arguments effectively.
If your naturalisation application is refused, you may request a reconsideration by the Home Office. However, this is a complex process and not always the most effective option. In many cases, a fresh application may be more appropriate.
At HM & Co. Solicitors, we will assess the reasons for refusal and advise you on the best route forward—whether that be a reconsideration or a new submission.
