Naturalisation and British Citizenship in 2025: Updated Rules and Processing Times

British citizenship remains a milestone for many migrants who have made the UK their permanent home. As of 2025, several updates to the naturalisation process and related immigration rules have impacted timelines, eligibility, and application strategies. At Hextons Law, we aim to break down these changes and provide clear guidance for those looking to take the next step in their immigration journey.

Eligibility Criteria

To apply for British citizenship through naturalisation, most applicants must still meet the following core requirements:

• Be aged 18 or over

• Have held Indefinite Leave to Remain (ILR), Settled Status, or Permanent Residence for at least 12 months (unless married to a British citizen)

• Have lawfully lived in the UK for 5 years (or 3 years if married to a British citizen)

• Have not been absent from the UK for more than 450 days in the last 5 years (or 270 days in the last 3 years)

• Have not been absent for more than 90 days in the last 12 months before applying

• Meet the English language and Life in the UK requirements

• Be of good character, with no serious criminal or immigration offences

What's Changed in 2025?

While the core requirements remain intact, some key updates include:

1. Increased Scrutiny on Good Character: There has been a notable increase in refusals where applicants had minor, historic offences or immigration breaches. Applicants should ensure they declare all issues transparently.

2. Digital Application Enhancements: The UK Home Office has streamlined the naturalisation process with more digital tools and verification systems, reducing reliance on physical documents and improving application efficiency.

3. Processing Times: Processing times remain variable. While the Home Office’s standard timeline is around 6 months, some applicants report delays up to 9 months due to backlogs.

4. Fee Structure: As of April 2025, the fee for a standard naturalisation application is £1,630. This includes the cost of the citizenship ceremony. Fee waivers remain unavailable for most adult applicants.

Application Process Overview

1. Confirm eligibility and prepare documents

2. Pass the Life in the UK test and meet language criteria

3. Submit the application online and upload supporting documents via UKVCAS

4. Attend a biometric appointment

5. Await a decision and attend a citizenship ceremony if approved

Common Pitfalls to Avoid

• Failure to disclose previous immigration breaches

• Not meeting residency requirements (especially days out of the UK)

• Failing to provide adequate documentation

• Using outdated evidence or expired test results
