You need two referees for a British citizenship application: each must have known you personally for at least three years, one must be a professional person of any nationality, and the other must hold a British passport and be either a professional or over 25. Referees cannot be related to you, to each other, or acting as your representative, and they cannot work for the Home Office.
TL;DR:
- Both referees must have known you for at least three years and cannot be related to you or each other, to avoid disqualification.
- The professional referee can be from any nationality, but the second referee must hold a British citizen passport; a different type of British passport does not qualify.
- The professional referee’s role covers a broad range of public trust positions, such as solicitors, doctors, teachers, and civil servants, all underpinned by official accountability.
- For child applications, the referee must have worked directly with the child, and if unavailable, two adult referees are acceptable with documented reasons for the alternative route.
- To prevent delays, verify all details with referees beforehand, including relationship length, passport type, and unspent convictions, and ensure signatures are original and signatures are accurate.

What are the citizenship referee requirements for adults?
Getting this wrong is one of the most common reasons naturalisation applications stall, so it pays to understand exactly who qualifies before you approach anyone.
The nationality policy guidance sets out a clear structure. Your first referee must be a professional person of any nationality who has known you personally for a requisite period. Your second referee must hold a British citizen passport and must either be a professional person or meet the age requirement.
“Professional person” is broader than many applicants assume. It covers the obvious candidates, but the Home Office guidance and Citizens Advice both point to a wide category of recognised roles rather than a narrow list.
Roles that typically qualify as professional referees:
- Solicitors, barristers, and chartered legal executives
- Doctors, dentists, and registered nurses
- Teachers, headteachers, and lecturers
- Accountants and financial advisers with recognised professional body membership
- Police officers, civil servants (outside the Home Office), and armed forces officers
- Ministers of religion and civic leaders such as councillors or magistrates
Each of these roles qualifies because the individual holds a position of recognised public trust, usually underpinned by a licence, registration, or professional body that could be checked if the Home Office had doubts about their standing. That underlying accountability is what the rule is really testing, not the job title itself.
The nationality requirement trips people up more than any other part of this. Your professional referee can be from anywhere in the world, provided they meet the standing and three year acquaintance test. Your second referee is different: they must hold a British citizen passport specifically. A British National (Overseas) passport, an Irish passport, or indefinite leave to remain does not satisfy this condition, even though all three might reasonably feel “British enough” to the applicant. The Home Office checks the passport type, not the person’s general connection to the UK.
If the second referee is not a professional, age becomes the qualifying factor instead, and they simply need to be over 25 with a valid British passport.
Both referees should be ready to produce identity and standing evidence if asked. The Confirming ID guidance describes what caseworkers may request, and it is worth having these ready before you submit rather than scrambling afterwards:
- Passport number and expiry date for both referees
- A practising certificate, professional membership card, or employer ID for the professional referee
- Proof of the British referee’s passport, since this is checked electronically against Home Office records
Pro Tip: *Ask each referee to photocopy or photograph their passport and professional ID before you submit the form.
Referee rules for child citizenship applications
Child applications follow a stricter logic, because the Home Office wants confirmation from someone who has actually dealt with the child in a professional capacity, not simply an adult who knows the family.
- Find a professional who has worked directly with the child. Acceptable referees include a teacher, GP, health visitor, or social worker who has had genuine professional contact with the child, not just a general practitioner who has seen the whole family once.
- Use this route only if no professional referee is available. Where a genuinely suitable professional cannot be found, the nationality policy guidance allows two appropriate adult referees instead, provided you can show why the usual route was not possible.
- Document your attempts. If you are relying on the adult referee alternative, keep evidence of the efforts you made: emails to the child’s school or GP surgery, appointment records, or written responses explaining why a professional referee could not be secured.
Home Office caseworkers do exercise a degree of discretion here, and a well documented paper trail showing genuine attempts to find a professional referee is often the deciding factor in whether the alternative route is accepted without further questions.
Who is not allowed to be a referee, and why convictions matter
The exclusion list is short but absolute, and it catches out more applicants than you might expect, usually because the “obvious” choice of referee turns out to be disqualified by a relationship the applicant had not considered a problem.
People who cannot act as your referee:
- Any relative of yours, by blood or marriage
- Anyone related to your other referee
- Your immigration adviser, solicitor, or anyone acting as your representative in the application
- Anyone currently employed by the Home Office
- Anyone who does not meet the three year acquaintance minimum, regardless of how well they know you now
The relative exclusion catches people out because it is drawn widely. A cousin, an in law, or a step parent all count, even if that person is genuinely a solicitor or GP who would otherwise be an ideal referee.
Criminal record is the other trap. A referee with a recent, unspent conviction can jeopardise the application, since the declaration effectively asks them to vouch for your good character while implicitly presenting their own standing. GOV.UK’s rehabilitation periods guidance sets out how long a conviction remains “unspent” depending on the sentence, and a spent conviction generally does not need to be disclosed or does not disqualify a referee in the way an unspent one might.
Under section 46(1) of the British Nationality Act 1981, knowingly making a false statement in connection with a citizenship application, including a false referee declaration, can lead to a fine of up to £5,000 and up to three months’ imprisonment. This is worth stating plainly to your chosen referees before they sign anything.
Quick checklist before you approach a referee:
- Confirm they are not related to you or to your other referee
- Confirm they have known you for three years or more
- Ask directly whether they have any unspent convictions
- Check their passport type matches what the role requires
Getting good character issues right the first time matters more than most applicants realise, and our guide to good character requirements covers this in more depth if you are unsure whether something in your own or a referee’s history could be a problem.
What do referees need to write on the form?
Whether you are using Form AN for an adult application or Form MN1 for a child, both referees complete a declaration section with specific fields the Home Office checks against other information in your application.
Information each referee must provide:
- Full name and current residential address
- Occupation, including employer name for professional referees
- Contact telephone number and email address
- Passport number (for the British passport holding referee)
- How long they have known you and in what capacity
- Confirmation that the photograph submitted is a true likeness of you
The “how long and in what capacity” section is where vague answers cause problems. “Known for years” is not enough detail. A caseworker wants something specific: “Known as a neighbour and family friend since 2019” or “Professional relationship as GP since 2020, personal friendship since 2021” gives them something concrete to weigh against your own account of the relationship.
Signature requirements are stricter than many applicants expect. The 1st Referee Declaration form is designed for an original wet signature, dated at the point of signing. A scanned or digitally inserted signature is unlikely to satisfy the Home Office, and applications submitted with photocopied signatures have been queried or rejected outright. If your referee lives abroad or you cannot get a physical signature easily, plan for this well ahead of your submission deadline rather than discovering the problem the day before you post the form.
Behind the scenes, the Confirming ID guidance explains that British referees’ passport details are checked electronically against Home Office records, which is one reason accuracy on the form matters more than it might first appear. A single transposed digit in a passport number can trigger a query that delays the whole file. If you want the fuller picture of how referee requirements sit within the broader citizenship application, our 2026 citizenship requirements guide walks through the whole process end to end.
Pre-submission checklist: avoiding referee delays
Most referee problems are avoidable with a short verification conversation before you submit, rather than an argument with the Home Office after you have already sent the form.
- Confirm the three year relationship with both referees in plain terms, and agree how they will describe it on the form.
- Verify passport types. Ask your second referee to check their passport specifically says “British Citizen”, not a different category.
- Rule out any relation between either referee and you, or between the two referees themselves.
- Ask about unspent convictions directly, however awkward it feels, since this is far better raised now than discovered later.
- Update contact details. An old mobile number or a house they moved out of two years ago will cause problems if the Home Office tries to verify anything by phone or post.
- Arrange wet signatures early, particularly if either referee lives at a distance or has a busy schedule.
Common mistakes that trigger delays:
- Using a British National (Overseas) or Irish passport instead of a British citizen passport
- Leaving out a phone number or using an email address the referee no longer checks
- Including a relative because “everyone else was busy”
- Submitting a photocopied or digitally signed declaration
- Writing a one-line description of the relationship with no dates or context
Pro Tip: When you approach a potential referee, ask them directly: “Have you known me personally for at least three years, are we unrelated, and do you have any unspent convictions?” A blunt question at the start saves an awkward conversation, or a rejected application, later.
What happens if a referee gets rejected?
If the Home Office has concerns about a referee, it typically writes to you requesting clarification or asking for a replacement referee altogether, rather than rejecting the whole application outright on that basis alone.
What to expect if a referee is queried:
- A written request for further evidence, such as proof of the referee’s professional standing or clarification of the relationship
- A request to nominate a replacement referee if the original does not meet the criteria
- An extended processing time while the Home Office waits for your response
Processing times can stretch by several weeks or more once a referee query is raised, since the file effectively pauses until you respond with a satisfactory replacement or explanation. This is one of the more frustrating outcomes for applicants who assumed their referees were straightforward, and it is entirely preventable with the checks covered above.
The seriousness of the referee declaration should not be understated. Under section 46(1) of the British Nationality Act 1981, a referee who knowingly gives false information faces a fine of up to £5,000, imprisonment of up to three months, or both. This is not a formality buried in small print. It is a genuine legal risk, and referees should understand exactly what they are signing before they put pen to paper.
When to get solicitor help and what MNS Solicitors can do
Some referee situations are genuinely difficult to judge alone. If you are unsure whether a family friend’s role counts as “professional,” if a potential referee has an old conviction and you are not sure whether it is spent, or if your application has an urgent deadline and a referee has just been queried, these are exactly the moments where a second opinion prevents a costly mistake.
The firm reviews referee eligibility as part of a wider naturalisation application check, looking at nationality, passport type, professional standing, and the acquaintance timeline before the form ever reaches the Home Office. Where a referee has already been queried or rejected, the firm can help prepare a replacement declaration and respond directly to Home Office correspondence, reducing the back and forth that often extends processing times. For applicants facing tight deadlines, a fast-track service is also available, with applications prepared in as little as 24 hours where circumstances demand it. Enquiries are handled by qualified solicitors from the outset, not passed to trainees, and pricing is fixed and confirmed upfront before any work begins.
Why the “obvious” referee choice is often the wrong one
Applicants tend to reach first for the referee who feels closest to them personally, and that instinct is exactly what causes most of the problems covered here. A best friend of fifteen years who happens to be self employed with no professional body membership will not satisfy the professional referee test, however well they know you. A brother-in-law who is a solicitor will not satisfy anything, because the relative exclusion overrides the professional qualification entirely.
The better approach is to work backwards from the rule, not forwards from the relationship. Ask yourself who in your life holds a recognised professional role and has known you personally, separately from that role, for three years. Then ask who holds a British passport and fits either the professional or over 25 test. If neither answer is obvious immediately, that is a signal to widen your search rather than compromise, because a marginal referee who half fits the criteria is far more likely to trigger a query than a clearly qualifying one who took an extra week to find.
Where genuine doubt exists, particularly for child applications where a professional referee is not available, documenting your search matters as much as the eventual choice. A folder of emails to schools or GP surgeries showing real attempts to secure the right referee often does more to satisfy a caseworker than a perfectly worded form ever could.

Get referee and application checks done properly, without the guesswork
Working out whether a friend, colleague, or family GP actually meets the referee criteria is exactly the kind of detail that is easy to get wrong once, and expensive to get wrong on a citizenship application. Mnssolicitors reviews referee eligibility, passport type, and professional standing as part of a full application check, so you find out about a problem before submission, not weeks into processing.
If your case is urgent, whether that is a looming deadline or a referee who has already been queried by the Home Office, the fast-track service can prepare replacement documents quickly. For naturalisation cases more broadly, the immigration services page covers everything from initial eligibility checks to full representation if the Home Office raises questions about your application.
Next steps if you want to move forward:
- Get a fixed price quote for a referee and eligibility check before you submit
- Ask about the fast-track option if you are working to a tight deadline

FAQ
Who can act as a referee for British citizenship?
You need two referees who have known you personally for at least three years. One must be a professional person of any nationality, and the other must hold a British citizen passport and be either a professional or over 25.
Can my friend be my referee for naturalisation?
Yes, provided they meet the criteria. A close friend can qualify as either referee as long as they satisfy the professional or passport and age requirements, have known you for three years, and are not related to you.
What happens if the Home Office rejects one of my referees?
The Home Office typically writes asking for clarification or a replacement referee, which can extend processing time by several weeks. Mnssolicitors can help prepare a compliant replacement declaration quickly if this happens to you.
Are the referee rules changing in 2026?
There is no indication in current Home Office guidance of a change to the core referee criteria for 2026. Always check the nationality policy guidance directly before submitting, since detailed procedural guidance can be updated between major rule changes.
