British citizenship registration — Section 1(4)

Registration as a British Citizen After the First 10 Years in the UK

Section 1(4) provides a registration framework for someone born in the UK who spent their first 10 years here within the applicable residence and absence framework. Applications can be made by children or adults.

Automatic British citizenship should be considered before the registration route is reviewed. This page identifies the section 1(4) framework and evidence areas only; it does not determine eligibility or predict a decision.

In brief

  • Section 1(4) is a registration framework for someone born in the UK who lived here for their first 10 years, within the residence and absence rules.
  • Check automatic British citizenship first — some UK-born people are already British.
  • It has an age framework and limits on absences during those first 10 years.
  • The guide explains the residence conditions and when higher absences may still be considered.

What section 1(4) covers

Section 1(4) of the British Nationality Act 1981 provides a route to registration as a British citizen for certain people born in the UK. The framework considers the applicable UK-birth date framework; whether the person has reached the relevant age; residence and absences during each of the first 10 years of life; and good character. (Guide T, pp. 4–5.)

The route is not limited to children. Guide T states that an application may be made by an adult or a child. Where the applicant is under 18, the application should normally be completed by a parent or guardian. (Guide T, p. 4.) This is a nationality registration route within the wider child-registration cluster — it is not an immigration long-residence route, and it identifies the framework rather than concluding that an individual is entitled to be registered.

Check automatic British citizenship first

A person born in the UK may already be a British citizen because of the circumstances at birth. Guide T states that where a parent was British or settled in the UK at the time of birth, the person may already be British and may not need to apply for registration. The applicable definition of “parent” can depend on the person’s date of birth. (Guide T, p. 4.)

Automatic citizenship should therefore be reviewed before section 1(4) — see automatic citizenship for a child born in the UK, and the wider automatic British citizenship explanation. This page cannot determine automatic citizenship where parentage, status or nationality history is disputed.

The UK-birth framework

Guide T applies to a person born in the UK on or after 1 January 1983. (Guide T, p. 4.) For this route, Guide T describes the UK as England, Scotland, Wales, Northern Ireland, the Channel Islands and the Isle of Man. (Guide T, pp. 4–5.)

The precise place and circumstances of birth form part of the framework to review.

The age framework

A section 1(4) application cannot be made until the person is at least 10 years old. It may then be made while the person is a child or after they become an adult. (Guide T, p. 4.)

The fact that an applicant is now over 18 does not, by itself, place the case outside the route described in Guide T.

Residence during the first 10 years

The residence framework examines the first 10 years of the person’s life. Guide T states that the ordinary framework permits no more than 90 days outside the UK in each of those years. The assessment is therefore structured year by year, rather than only by reference to one total absence figure for the entire decade. (Guide T, pp. 4–5.)

Residence records may need to cover early childhood as well as school years. Passports may assist, but Guide T cautions that they may not be sufficient to demonstrate residence throughout the complete period. (Guide T, p. 12.)

This page identifies the framework only. It does not calculate absences or determine the treatment of individual journeys.

Absences above the ordinary framework

Guide T confirms that the Home Secretary has discretion to disregard absences above the ordinary limit. An applicant relying on special circumstances is directed to explain those circumstances in the application. (Guide T, p. 4.)

The guide says excess absences will normally be waived where:

  • absences in any one year do not exceed 180 days and total absences across the first 10 years do not exceed 990 days; or
  • those figures are exceeded but the excess resulted from circumstances beyond the applicant’s control, such as serious illness.

Guide T also says excess absences would not normally be waived simply because the person’s parents did not know about the absence framework, or where the absences were entirely voluntary. (Guide T, p. 5.)

These figures describe the published guidance. They must not be treated as a score, guarantee or predicted decision, and official guidance should be checked because it can change. Extensive absences, disputed travel history or reliance on exceptional circumstances may require advice outside our straightforward-matter boundary — Refusal or complex issue → immigration help.

Good character

Good character forms part of the statutory section 1(4) framework. Guide T directs applicants to the separate Home Office good-character policy guidance used by decision-makers. The issues considered under that guidance can extend beyond criminal convictions — Guide T discusses matters including criminality, immigration history, deception and financial conduct. (Guide T, pp. 4–9.)

This route page does not reproduce the complete good-character framework — for that, see good character. Contentious or complex good-character matters should be directed to Immigration Help.

Applications by children and adults

Both children and adults can use the section 1(4) application framework described in Guide T. (Guide T, p. 4.) For an applicant under 18, the application should normally be completed by a parent or guardian using the child’s details. (Guide T, p. 4.)

Referees and identity checks. Guide T states that an application must be endorsed by two referees who satisfy the relevant referee framework; each referee must have known the applicant for at least three years and must not fall within the prohibited relationships or roles listed in the guide. For a child applicant, at least one referee should ordinarily be a person who has dealt with the child in a professional role, such as a teacher, doctor, health visitor or social worker, and the guide provides an alternative where attempts to obtain such a referee are documented. (Guide T, p. 10.) Applicants must also follow the biometric enrolment process; children applying for registration are included, although the biometric information taken varies according to age. (Guide T, p. 11.) Current application instructions should be checked before submission because administrative processes can change.

Registration does not provide immigration permission

A citizenship application does not itself provide immigration permission in the UK. Guide T states that an applicant must continue to demonstrate any separate entitlement needed to enter or remain in the UK while the application is being considered. (Guide T, pp. 13 and 15.)

Nationality registration and immigration status should therefore be treated as separate issues. Where immigration status is uncertain alongside a nationality question, see immigration help.

Issues and evidence areas to review

  • Whether the person may already be a British citizen automatically
  • The place and applicable date framework for the person’s birth
  • Whether the relevant section 1(4) age framework has been reached
  • Residence during each of the first 10 years of life
  • Absences during each individual year
  • Whether any absences fall outside the ordinary framework
  • The reasons for and evidence concerning any excess absences
  • The good-character framework
  • Whether the application is for a child or an adult
  • Whether nationality, parentage, residence or immigration history is disputed

Passports may not establish continuous residence by themselves, and evidence may need to address periods before the person started school. (Guide T, p. 12.) These are framework labels and evidence areas only; they do not determine registration entitlement. For the shared evidence framework, see evidence of a citizenship claim.

Our regulatory scope. ENS Immigration Advice is regulated by the Immigration Advice Authority at Level 1 and can assist with a straightforward section 1(4) application by identifying the applicable framework and the evidence areas that may need review. Disputed automatic citizenship, disputed parentage or nationality history, disputed residence, extensive or exceptional excess-absence cases, contentious good-character matters, an existing refusal and any other complex nationality issue fall outside that pathway — we will identify the framework and direct you to the appropriate next step. This page does not determine whether a person is already British or whether they can be registered. Refusal or complex issue → specialist referral.

Disputed residence, disputed nationality or parentage, exceptional absences and refusals are directed to the right level of help.

Frequently asked questions

What is section 1(4) registration?

Section 1(4) is a British citizenship registration framework for certain people born in the UK who lived here during their first 10 years. It considers UK birth, age, residence, absences and good character. (Guide T, pp. 4–5.)

Is section 1(4) only for children?

No. Guide T states that an application can be made by an adult or a child. Where the applicant is under 18, the form should normally be completed by a parent or guardian. (Guide T, p. 4.)

Could someone born in the UK already be British?

Yes. Guide T says a person may already be British where a parent was British or settled in the UK at the time of birth. The applicable definition of “parent” may depend on the date of birth. Automatic citizenship should be reviewed before registration. (Guide T, p. 4.)

Does section 1(4) use the same framework as section 1(3)?

No. Guide T describes section 1(4) by reference to UK birth, age, residence during the first 10 years, absences and good character. Section 1(3) is an adjacent route concerning a parent who later becomes British or settled. (Guide T, p. 4.)

How is residence considered?

Guide T examines absences during each of the first 10 years of life. The ordinary framework permits no more than 90 days outside the UK in each year. (Guide T, pp. 4–5.)

Can excess absences be considered?

Guide T confirms that the Home Secretary has discretion to disregard excess absences. It sets out circumstances in which excess absences will normally be waived, while making clear that some voluntary absences or parental unawareness would not normally be sufficient. (Guide T, pp. 4–5.)

What evidence can show residence during the first 10 years?

Guide T identifies passports, school letters, medical records, nursery records and other documents showing residence. It cautions that passports alone may not cover the complete period. (Guide T, p. 12.)

Does the parent’s current immigration status control this route?

The core section 1(4) framework in Guide T is based on the applicant’s birth, age, residence, absences and good character. A parent’s status can nevertheless be relevant when reviewing whether the person was already British or whether another registration route may apply. (Guide T, p. 4.)

Does making a citizenship application give immigration permission?

No. Guide T states that a citizenship application does not provide immigration permission. Any separate permission needed to enter or remain in the UK must be considered independently. (Guide T, pp. 13 and 15.)

How can ENS Immigration Advice help?

ENS Immigration Advice can provide an initial assessment of a straightforward section 1(4) application, identify issues and evidence areas for review and explain adjacent citizenship frameworks. Refusals, disputed history and complex or exceptional matters should be directed to complex immigration help.

Source basis. Built from Guide T: Registration as a British citizen — A guide for those born in the UK on or after 1 January 1983 who have lived in the UK up to the age of 10 (August 2026), which is dedicated to registration under section 1(4). Guide T states that it is intended to assist with an application and is not a complete statement of nationality law or policy: it does not provide a complete method for allocating individual journeys to each year of the first decade; it does not fully explain the date-sensitive definition of “parent”; it does not provide a complete historic analysis of British citizenship or settled status at the time of birth; it does not determine how discretion will be exercised in an individual excess-absence case; the complete good-character decision framework sits in separate Home Office policy guidance; and it does not resolve disputed nationality, parentage, residence or immigration history. Nationality law and Home Office guidance can change; current official guidance should be checked against GOV.UK before a registration application is submitted.
