The Good Character Requirement for British Citizenship
The most discretionary — and most misunderstood — part of naturalising. What the Home Office assesses, the 2026 thresholds, the illegal-entry rule, and how to reduce your risk of refusal.
Good character is a mandatory test for British citizenship, and one of the most common reasons applications fail. It applies to everyone aged 10 or over, and because the British Nationality Act 1981 does not define it, the Home Office decides it under detailed policy guidance covering criminality, immigration history, finances and honesty. You can meet the residence, English and Life in the UK requirements in full and still be refused — which is why understanding it before you apply matters.
What “good character” means
There is no statutory definition. Instead, the Home Office assesses your conduct — past and present — against policy guidance for caseworkers, the current version of which was published on 30 April 2026. The test is deliberately broad and discretionary: caseworkers weigh negative and positive factors together and reach a judgment. Some conduct is serious enough that an applicant “will normally” be refused; below that threshold, the caseworker decides whether you are of good character on the balance of probabilities. Unlike some visa decisions, meeting the other criteria does not create an entitlement — the Home Office retains wide judgment here.
What the Home Office assesses
The assessment looks across your whole record, not just criminal history.
| Area | What it covers |
|---|---|
| Criminality | UK and overseas convictions, cautions and pending charges — assessed against the thresholds below |
| Immigration history | Overstaying, working in breach of conditions, deception, and illegal entry |
| Financial conduct | Tax and HMRC compliance, debts to public bodies, unpaid CCJs, bankruptcy |
| Honesty & disclosure | Deception or non-disclosure in any application — a refusal ground in its own right |
| Other conduct | Notoriety, behaviour that calls integrity into question, or previous deprivation of citizenship |

Criminality thresholds
Since 31 July 2023, the criminality thresholds have been aligned with Part 9 of the Immigration Rules. In broad terms:
| Sentence or disposal | Likely outcome |
|---|---|
| Custodial sentence of 12 months or more | Will normally be refused |
| Custodial sentence under 12 months | Discretionary — balance of probabilities |
| Non-custodial sentence or community order | Discretionary — balance of probabilities |
| Out-of-court disposal (caution, warning) | Discretionary — considered on the facts |
| Fixed penalty notice (e.g. minor speeding) | Not normally a refusal unless unpaid or it led to a conviction |
| Pending charge or prosecution | Not normally granted until the charge is resolved |

A pattern of minor offences — for example, several driving offences in a short period — can also count against you even where each on its own would not.
The illegal-entry rule
The most significant recent change concerns how someone entered the UK. For applications made on or after 10 February 2025, guidance directs caseworkers that an application which includes illegal entry — entering without permission, by clandestine means, or via a dangerous journey — will normally be refused, regardless of how long ago the entry took place, and even where the person now holds ILR.
The version published on 30 April 2026 keeps that starting point but sets out important limits. Illegal entry should usually be set aside where it was outside the person’s control — for example a child, or someone under the control of traffickers — and the guidance expressly addresses Article 31 of the Refugee Convention, so a refugee with a valid legal defence for how they entered must not be refused on that basis alone.
Finances, tax and debt
Financial conduct carries real weight, and catches out applicants who assume only criminal matters count. The Home Office looks at whether you have paid tax that was due, whether you owe money to public bodies, and whether you have unresolved debts. Deliberate non-payment of tax, or an evasive HMRC history, is treated seriously. A County Court Judgment does not automatically bar you — you can often succeed if you show you are actively repaying it — but undisclosed debts and a pattern of financial irresponsibility can lead to refusal. Bankruptcy and unpaid NHS charges may also be considered.
Disclosure — the biggest avoidable trap
The single most common way to fail good character unnecessarily is non-disclosure. You must declare everything: all convictions, cautions and out-of-court disposals, UK and overseas, including spent convictions; fixed penalties; and relevant matters such as previous visa refusals from other countries. The danger is that failing to declare a minor issue converts it into a question of honesty — and dishonesty is itself a good character failing, often more damaging than the original matter would have been.
If you are refused
There is no right of appeal against a citizenship refusal, but a refusal is not the end of the road. You generally have three options: ask the Home Office to reconsider the decision — under guidance updated in June 2026, a reconsideration request is expected within six months of the decision date; make a fresh application, which is assessed under the current guidance; or, in limited cases, challenge the decision by judicial review. The application fee is not refunded on refusal (the ceremony element is), so it is far better to get the assessment right first time. Which route is best depends entirely on why you were refused.
Before you reach this stage, confirm the rest of your application is sound: check your timing with the naturalisation calculator, and read the full British citizenship after ILR guide for how good character fits the wider process.

Our editorial and accuracy standards
ILR Calculator UK is an independent, free settlement-planning resource. This page summarises the Home Office good character guidance and the British Nationality Act 1981, with the primary sources linked at the point they are used. Because this guidance changes often — most recently on 30 April 2026 — we review the page after each update and record the review date at the top.
Good character is highly fact-sensitive and, in areas such as illegal entry, contested and subject to legal challenge.
