British Citizenship Referee Requirements 2026: Who Can Act as a Referee?

In Brief

A British citizenship application normally requires two referees. One referee can be of any nationality but must be an acceptable professional person. The other must hold a British citizen passport and must either be a professional person or be over the age of 25. For an adult application, both referees must have known the applicant personally for at least three years.

Referee requirements are easy to underestimate. A referee who does not meet the Home Office criteria can lead to questions, a request for a replacement referee and avoidable delay. The referee information must also be consistent with the rest of the application.

Our British citizenship and nationality solicitors advise on naturalisation and registration applications, including referee eligibility, residence, absences, good character and supporting evidence. This guide reflects the published Home Office guidance available on 29 July 2026.

Why Are Referees Needed for a British Citizenship Application?

Referees are used principally to help establish the applicant’s identity and protect the integrity of the nationality application process. The Home Office may carry out checks to confirm that a referee is qualified to act and that the information and signature supplied are genuine.

A referee is not deciding whether the applicant satisfies the legal requirements for British citizenship. The Home Office remains responsible for assessing matters such as residence, lawful status, absences, English language, the Life in the UK requirement and good character. However, the referee declarations form part of the application, and inaccurate or unsuitable referee information can create an unnecessary problem.

Applicants should therefore treat the referee section with the same care as every other part of the citizenship application. It is not a formality that should be completed at the last minute.

How Many Referees Are Needed for British Citizenship?

You must normally provide two referees. They perform the same general identity-supporting function, but they do not have identical eligibility requirements.

Who Can Be the Professional Referee?

The first referee can be of any nationality, but they must be a professional person. The relevant question is not simply whether the person has a respectable job or senior title. Their profession or position should fall within the Home Office’s accepted categories, or their professional standing should be sufficiently clear under the applicable guidance.

Examples include accountants, barristers, permanent civil servants, police officers, solicitors, teachers, lecturers, social workers and professionally qualified engineers. The complete published list is set out later in this guide.

The professional referee must also satisfy the general referee requirements. For an adult applicant, they must have known the applicant personally for at least three years, must not be related to the applicant or the other referee, must not be the applicant’s representative in the application and must not be employed by the Home Office.

Who Can Be the British Citizen Referee?

The second referee must hold a British citizen passport. They must also be either:

• an acceptable professional person; or
• over the age of 25.

This means the British citizen referee does not necessarily need to be a professional person if they are over 25. They must, however, hold the required British citizen passport and comply with the other referee rules, including the three-year acquaintance requirement for adult applicants.

Do not rely on nationality alone. A person may describe themselves as British but not hold a British citizen passport, or may hold another form of British nationality. The application asks for specific passport information, so this should be checked before the person agrees to act.

What Rules Must Both British Citizenship Referees Meet?

For an adult application, each referee must have known the applicant personally for at least three years. In addition, neither referee should be:

• related to the applicant;
• related to the other referee;
• the solicitor or agent representing the applicant in the citizenship application;
• employed by the Home Office; or
• a person who has been convicted of an imprisonable offence during the previous ten years.

The current published nationality guidance does not list every circumstance that might cause the Home Office to question a referee. Applicants should choose people whose identity, status, contact details and relationship with the applicant can be verified without difficulty.

Acceptable Professional Persons for a British Citizenship Referee

The Home Office maintains a published list of acceptable professional persons. The list below reflects the nationality caseworker guidance available at the date of this article. Because official guidance can change, applicants should check the latest Home Office nationality guidance before submitting an application.

Important: inclusion of a job title in the table does not remove the other requirements. The person must still have known an adult applicant personally for at least three years and must satisfy the independence and suitability rules.

A Practical British Citizenship Referee Checklist

Before entering referee details in the application, use the following checks.

Can an Employer Act as a British Citizenship Referee?

An employer can act as a referee only if the individual concerned meets the relevant referee requirements. Employment status by itself is not enough.

For example, a director, manager or personnel officer may fall within an accepted category in specified circumstances, such as where the company is VAT registered. The person must also have personally known the applicant for at least three years. A recently appointed manager who only knows the applicant through a personnel file is unlikely to satisfy the personal acquaintance requirement.

Applicants should avoid describing a referee too generally. If the accepted category depends on the organisation’s status, professional membership or qualification, the description should be accurate and capable of verification.

Can a Friend Act as a British Citizenship Referee?

A friend may qualify as the British citizen referee if they hold a British citizen passport, are over 25 or are an acceptable professional person, and have known the applicant personally for at least three years.

A friend can also act as the professional referee if they genuinely hold an accepted professional position. The fact that the relationship is social does not prevent the person from acting, provided all the rules are met. A relative cannot act merely because the applicant also regards them as a friend.

Can a Doctor or GP Be a British Citizenship Referee?

Applicants should not assume that a doctor or GP automatically qualifies as the professional referee for an adult citizenship application. The current published list of acceptable professional persons does not simply include “doctor” or “GP” as a general adult category.

A medical professional may qualify through another recognised professional status, and the rules for child applications are different because a professional who has dealt with the child, such as a doctor or health visitor, may be appropriate. Where there is uncertainty, it is safer to check the current guidance or select a referee whose eligibility is clear.

Can the Applicant’s Solicitor Be a Referee?

A solicitor can be an acceptable professional person, but the solicitor or agent representing the applicant in the citizenship application cannot act as that applicant’s referee.

This distinction matters. A solicitor who knows the applicant socially or through an unrelated professional context may still face an apparent conflict if they or their firm are instructed on the nationality application. The safer course is to use an independent referee.

Do Referees Have to Live at a Different Address?

The current published British nationality guidance identifies specific prohibited relationships and conflicts but does not expressly state that sharing an address is, by itself, an automatic bar for a citizenship referee. Applicants should not confuse British citizenship referee rules with the separate rules used for passport referees or countersignatories.

Even so, a shared address may prompt questions about whether the referee is related to the applicant or whether the relationship has been described accurately. Where a clearly independent referee is available, using that person may reduce avoidable uncertainty.

British Citizenship Referees for a Child Application

Different considerations apply to a child’s registration application. At least one referee should normally be a professional who has dealt with the child in a professional capacity, such as a teacher, doctor, health visitor, social worker or minister of religion.

The other referee must normally hold a British citizen passport and be either a professional person or over 25. The referees must not be related to the child or to each other, must not be acting as the solicitor or agent for the application and must not be employed by the Home Office.

Home Office caseworker guidance recognises that a child may sometimes be unable to provide a referee who has dealt with them professionally. Where attempts to obtain such a referee are evidenced, two referees meeting the adult criteria may be considered. This should not be assumed without reviewing the specific application route and evidence.

What if the Applicant Lives Outside the UK?

Where an applicant is living outside the UK and does not know a British citizen passport holder who can meet the requirements, the guidance allows a Commonwealth citizen or a citizen of the country in which the applicant lives to act in limited circumstances. The person must have professional standing, meet the other requirements and have a signature considered acceptable by the relevant consul.

This is an exception rather than a general alternative. Applicants overseas should review the guidance for their particular form and route before relying on it.

What Information Do British Citizenship Referees Provide?

The exact process depends on whether the application is made online or by using a paper form. The application may request information including:

• the referee’s full name and date of birth;
• home or professional address and contact details;
• occupation, professional status or qualification;
• British passport details for the British citizen referee;
• how the referee knows the applicant;
• how long the referee has known the applicant; and
• a declaration confirming that the information supplied is true.

Paper nationality forms also contain specific photograph and endorsement instructions. Applicants should follow the instructions generated by the online application or contained in the current paper form rather than relying on an old declaration or an example found online.

Common Mistakes with British Citizenship Referees

Assuming a Job Title Automatically Qualifies

A senior-sounding title is not necessarily an accepted professional category. Check the person’s actual role, qualification, professional membership and the status of their organisation where relevant.

Using a Referee Who Has Known the Applicant for Less Than Three Years

For an adult application, each referee must have known the applicant personally for at least three years. A strong professional relationship of two years and eleven months does not meet a three-year requirement.

Choosing a British Referee Without Checking Their Passport

The second referee must be the holder of a British citizen passport. Check this before submitting the application and make sure the passport details are entered accurately.

Using a Relative or Connected Referees

Neither referee can be related to the applicant, and the referees cannot be related to one another. This includes relationships that may not be obvious from surnames alone.

Using the Solicitor Conducting the Application

A solicitor may be on the professional list, but the representative acting on the application cannot also provide the referee declaration.

Giving Inconsistent Information

Differences in names, dates, addresses, occupation or the stated length and nature of the relationship may result in questions. Referee details should be checked against the rest of the application before submission.

Leaving Referees Until the Last Minute

A proposed referee may decline, may not have a British citizen passport, may not fall within an accepted profession or may not be available to complete the declaration. Identify suitable referees before finalising the application.

What Happens if a Referee Does Not Meet the Requirements?

Current Home Office caseworker guidance states that where it is clear a referee does not meet the requirements, the applicant should be asked to provide a different referee. This can delay the application and may generate further scrutiny of the information supplied.

An unsuitable referee should not therefore be described as causing an automatic refusal in every case. However, failing to respond to a request, providing another unsuitable referee or supplying inaccurate information can put the application at risk. Deliberately or recklessly providing false information is a criminal offence.

Will the Home Office Contact British Citizenship Referees?

The Home Office does not contact every referee. Its published caseworker guidance indicates that referees should be contacted where doing so could resolve concerns about the application and the caseworker has the appropriate authority.

A referee should nevertheless be prepared to respond. Applicants should provide current contact details and should tell each referee that the Home Office may make enquiries. A referee who ignores communications or gives information inconsistent with the application may cause delay.

Best Practice Before Submitting Your Citizenship Application

1. Choose referees early. Do not wait until the application is ready to submit.
2. Use one clearly qualifying professional. Avoid borderline job descriptions where a straightforward alternative is available.
3. Check the British citizen passport requirement. Do not rely on assumptions about nationality.
4. Calculate the three-year period carefully. Both referees must meet it for an adult application.
5. Check independence. Confirm there is no prohibited family relationship, representative conflict or Home Office employment.
6. Verify every detail. Names, dates, addresses, passport information, job titles and relationship descriptions should be accurate.
7. Brief the referees. Explain what the application is, what they are confirming and that they may be contacted.
8. Review the correct form and guidance. Referee instructions can differ between naturalisation, adult registration and child registration routes.

Applicants with complex nationality histories, criminal or civil penalties, disputed residence, excessive absences, identity discrepancies or uncertainty about the correct route should obtain advice on the application as a whole rather than treating the referee section in isolation. Our individual immigration solicitors can assess the relevant nationality route and supporting evidence.

Frequently Asked Questions About British Citizenship Referees

Who can be a referee for a British citizenship application?

For an adult application, one referee can be of any nationality but must be an acceptable professional person. The other must hold a British citizen passport and must either be a professional person or be over 25. Both must normally have known the applicant for at least three years.

Do both citizenship referees need to be British?

No. The professional referee can be of any nationality. The other referee must hold a British citizen passport.

Do both referees need to be professionals?

No. The first referee must be a professional person. The British citizen referee can instead qualify by being over 25, provided they meet all the other requirements.

Can a family member be a referee?

No. A referee must not be related to the applicant. The two referees must also not be related to one another.

Can my manager be my professional referee?

Possibly, but not simply because they are a manager. Their position must fall within an accepted professional category, and they must have known you personally for at least three years.

Can my friend be the British citizen referee?

Yes, provided the friend holds a British citizen passport, is either over 25 or a professional person, has known you for at least three years and meets the other suitability rules.

Can my immigration solicitor be my referee?

No, not where that solicitor or agent is representing you in the citizenship application. A different, independent referee should be used.

What if I have not known any professional person for three years?

You should not use a person who fails the requirement merely to complete the form. Consider whether another accepted professional has known you in a personal capacity for the required period. Where no clear referee is available, obtain advice before applying.

Can both referees use the same profession?

The guidance does not require different professions. The important point is that each referee independently satisfies the criteria applying to their role.

Does the Home Office always contact referees?

No. Referees may be contacted where enquiries could resolve concerns, but contact is not automatic in every application.

Can a referee withdraw after the application is submitted?

A person can tell the applicant or Home Office that they no longer wish to act. A replacement declaration may then be required, which can delay the application. Applicants should choose referees who understand the commitment before submission.

Where can I check the official rules?

The requirements for naturalisation applicants are set out in the current Form AN guidance. Applicants using another registration route should read the guidance for that specific form because child and overseas cases can involve additional provisions.
