How to get a child passport in the UK

ByThiago SF

Travelling abroad with your child begins with one essential step — obtaining a valid passport.

A child passport not only proves your child’s British nationality but also ensures smooth travel and proper identification whenever needed.

Although the process may seem detailed, applying for a child passport in the United Kingdom is clear, secure, and easy to complete online or by post.
Here’s everything you need to know — from eligibility and documents to fees, tracking, and support.

✅ Eligibility and When to Apply

Before starting an application, you must confirm that your child qualifies for a British passport.

A child passport can be issued if:

  • The child is under 16 years of age.
  • The child is a British citizen, either by birth, descent, or naturalisation of a parent.
  • The applicant (parent or guardian) has parental responsibility.
  • You are applying for the first passport or a replacement (for a lost, stolen, or expired document).

You can apply at any time, even before planning a specific trip. The passport is valid for five years, so it’s advisable to apply or renew early to avoid delays during busy travel seasons.

📄 Required Documents and Legal Evidence

To ensure a successful application, you’ll need to provide several supporting documents proving identity, nationality, and parental responsibility.

Typical documents include:

  • The child’s full birth certificate or adoption certificate showing parental details.
  • Any existing passport(s) for the child (UK or foreign).
  • Proof of British nationality if not automatically evident (for example, a parent’s British passport).
  • Legal name-change documents (such as a deed poll or court order), if applicable.
  • A digital photograph that meets official UK passport standards.

If applying by post, you may also need a countersignatory — a person who confirms your child’s identity and signs the form and photo. This person must know you personally for at least two years, be over 18, and hold a valid UK or Irish passport.

Having all documents complete and accurate from the start will prevent delays or requests for further evidence.

💻 Application Methods: Online and Postal

You can apply for your child’s passport online or by using a paper form from the Post Office.

Online Application
This is the most efficient option. You complete the form digitally, upload a compliant photo, pay the fee by card, and send any physical documents or old passports by post when instructed. Someone will then receive an email to confirm your child’s identity — usually a friend, teacher, or professional who knows you well.

Postal Application
You can collect a paper form from a Post Office offering passport services. Fill it out carefully, attach photos, and include all required documents. For added security, use the Check & Send service (an extra £16) so that staff can review your paperwork before submission.

Both routes lead to the same outcome, but the online method is faster and slightly cheaper.

💷 Costs, Validity, and Urgent Services

The cost of a child passport depends on how you apply.

Current fees (as of 2025):

  • Online application: £61.50
  • Paper (postal) application: £74
  • Check & Send service (optional): +£16

Child passports are valid for five years. If you need a passport urgently, the 1-Week Fast Track service is available for children as well, costing £151. This service requires booking an appointment at a passport office and attending in person.

It’s worth planning ahead to avoid extra costs, but the Fast Track option is ideal for last-minute travel or emergencies.

📦 Delivery, Tracking, and Support

Once your application is submitted, you’ll receive updates by email or text message. You can track progress using the reference number that begins with PEX or POD.

Passports are delivered via Royal Mail Tracked Delivery, and a signature is required upon receipt. Supporting documents such as birth certificates are returned separately. If you prefer secure return delivery, you can pay an extra £5 for recorded post.

For assistance at any point, contact His Majesty’s Passport Office:

  • Passport Adviceline (UK): 0300 222 0000
  • Overseas: +44 (0)300 222 0000
  • Opening hours: Monday – Friday 8 am – 8 pm; weekends 9 am – 5:30 pm

The advisers can help you check which documents are needed or resolve issues with identity verification.
