The good character requirement for British citizenship

Last reviewed 13 August 2026 · Reviewed by the BritainTest editorial team

To become a British citizen, whether by naturalisation or by registration, anyone aged 10 or over must be of good character. It is one of the requirements our naturalisation guide summarises; this page explains it in more detail. Good character is not defined in law and is assessed case by case by the Home Office. This is general information, not immigration advice.

What good character means

There is no single legal definition of good character. Instead, Home Office caseworkers follow published guidance and weigh up a person's conduct and history. It applies to citizenship applications for anyone aged 10 or over, and a decision is made on the whole picture rather than any one factor.

What the Home Office considers

The guidance sets out broad areas a caseworker looks at, including:

• Criminality: convictions, cautions and the seriousness of any sentence;
• Immigration history: complying with immigration law (see below);
• Financial soundness: for example bankruptcy, or deliberate non-payment of tax or debts to public funds;
• Honesty: deception or dishonesty in dealings with the Home Office or other authorities;
• Notoriety: conduct that makes a person notorious in their community; and
• Serious matters: involvement in war crimes, terrorism or other serious harm.

This list is not exhaustive, and each application is judged on its own facts.

Immigration history

How a person has complied with immigration law is an important part of the assessment. Overstaying, working in breach of conditions, or entering the UK unlawfully can all count against an application. In particular, under guidance in force from 10 February 2025, applications that involve illegal entry are normally refused. Because this is a fast-changing area, check the current GOV.UK position before relying on anything here.

Honesty in your application

Being truthful and complete matters in its own right. Giving false information or leaving out something relevant can lead to refusal, and citizenship obtained by deception can later be taken away. If you are unsure whether to mention something, the safer course is to disclose it and check the guidance, rather than omit it.

If you are unsure

Because good character is judged case by case, a past issue does not automatically bar you, and a clean record is not an automatic pass. If your situation is not straightforward, do not guess from this guide: read the current GOV.UK guidance, and consider speaking to a qualified, regulated immigration adviser before you apply.
