UK Child Passport Renewal: Cost, Process & Requirements

If you’re a parent in the UK, renewing your child’s passport raises questions about costs, consent, and getting a photo of a wriggling toddler approved. The official process is more straightforward than many assume, though the rules differ from adult renewals.

Online application cost: £66.50 ·
Paper application cost: £80.00 ·
Child passport validity: 5 years ·
Standard processing time: Approximately 3 weeks ·
Applicable age: Under 16

Five key data points that define the UK child passport renewal landscape, drawn from official government and post office sources.

Can I renew my child’s British passport online?

Eligibility for online renewal

You can renew a child passport online if the child is under 16 and their passport hasn’t been expired for more than 5 years, according to GOV.UK (official passport guidance). The online route is designed for straightforward renewals — where the child’s appearance hasn’t changed dramatically and the old passport is available for submission.

• The child must be under 16 at time of renewal.
• The current passport must not have been expired more than 5 years.
• You must have the original passport document (not a photocopy).

Step-by-step online application process

The online application flows through the official GOV.UK portal. Here’s how it works:

1. Go to GOV.UK and select the online renewal option.
2. Enter your child’s current passport details and your parental details.
3. Upload a digital photo of your child (35 × 45mm dimensions required, meeting UK passport photo standards).
4. Pay the £66.50 fee using a debit or credit card.
5. After submission, arrange identity confirmation — someone who has known the child for at least 2 years, such as a GP or teacher, can verify the child’s identity online for under-12s.
6. Send the old passport to HM Passport Office within 30 days.

Documents required for online renewal

When applying online, you’ll need the following, per Post Office (renewal service guide):

• Your child’s current passport (the actual document, not a copy).
• A digital photo meeting UK standards (plain background, neutral expression, no shadows).
• Details of both parents (even if one parent has sole responsibility).
• Documents showing any name changes (e.g., adoption certificate, marriage certificate if applicable).

What is the fastest way to renew a child’s passport?

Standard processing times

GOV.UK currently advises that standard processing takes approximately 3 weeks for a child passport renewal. The online route is generally faster than postal applications because there’s less manual handling, and any errors in the form can be flagged immediately rather than weeks later. The RAC Drive (UK travel advice service) notes that applying online costs less and often results in quicker turnaround times due to reduced postal delays.

Fast Track and Premium services

There’s a catch: as of 2026, there is no official fast track service specifically for child passport renewals. Adult applicants have access to 1-week Fast Track (£166) or online Premium (1-day) services, but these are not available for children under 16. The Post Office (Check & Send platform) offers a Digital Check & Send service for £82.50 total (including a £16 fee) which can help reduce application errors — but this does not guarantee priority processing over a standard online application.

Post Office Check and Send

Post Office Check & Send involves a trained staff member reviewing your documents before submission. The service costs an additional £16 on top of the application fee. While it can prevent costly delays from incorrect photos or missing documents, it doesn’t fast-track the processing itself. According to the Post Office (service description), this is a practical option for parents who want reassurance that their paperwork is correct but should not be mistaken for an expedited service.

Do both parents need to be present for child passport renewal in the UK?

Parental consent requirements

Both parents must provide consent for a child passport renewal, but neither needs to be physically present at the time of application, according to GOV.UK (parental consent protocols). Consent is given by providing the other parent’s full name, address, and passport details on the application form. The system then checks this information against Home Office records.

• Consent is given via the application form, not in person.
• Both parents named on the birth certificate (and with parental responsibility) must be listed.
• If one parent cannot be contacted, a statement explaining the situation is required.

Single parent applications

If you have sole parental responsibility, you can apply without the other parent’s involvement. You’ll need to provide evidence of sole responsibility — such as a court order, local authority care order, or parental responsibility agreement — when submitting the application. The RAC Drive (travel guidance) states that separated parents “need to be upfront” about consent and custody arrangements, as HM Passport Office checks these details carefully.

Separated parents and consent

For separated parents, the situation can be more complicated. Even if your ex-partner isn’t involved in daily care, they still hold parental responsibility (unless a court has removed it). If the other parent refuses consent, a court order may be needed to proceed without their approval. GOV.UK (guidance for separated families) advises that you should seek legal advice if consent is refused, as applying without proper consent can result in the application being stopped and the passport being invalidated.

How long does a UK child passport last before it expires?

Validity period for under-16 passports

A child passport in the UK is valid for 5 years from the date of issue, according to Passport Photo Online (UK passport guidance). This is significantly shorter than the 10-year validity of adult passports, reflecting the fact that children’s appearances change rapidly. Once the passport expires, it cannot be extended — you must go through the full renewal process again.

Passport expiry and travel considerations

Travelling with a child passport requires careful timing. Many countries require that your passport has at least 6 months’ validity remaining from the date of entry — meaning a passport issued 4.5 years ago might not be valid for travel to certain destinations. Additionally, the Global British Passports (overseas services) service notes that supporting documents and photos must meet UK standards even when applying from abroad, so if your child’s passport has less than 6 months remaining before expiry, start the renewal process early to avoid travel disruption.

The implication: parents should check travel destinations’ validity requirements and renew well before the 5-year expiration to avoid last-minute complications.

Does my child need a new passport when they turn 16 in the UK?

Age 16 and adult passport eligibility

Yes, once your child turns 16, they can no longer renew their child passport. Instead, they must apply for a first adult passport — which is treated as a new application, not a renewal. According to GOV.UK (age transition rules), this applies even if the child passport still has several months of validity left; the child passport system simply doesn’t allow extensions or partial renewals.

Applying for a first adult passport

The first adult passport application requires:

• The old child passport (to verify identity).
• A new digital photo — the adult passport photo standards are slightly different, and the applicant must sign the photo themselves.
• Two countersignatures from a professional (GP, teacher, accountant) who has known the applicant for at least 2 years — countersigning is required for first adult passports.
• A fee of £88.50 for online applications, or £100 for postal applications (as of 2025-26).

The pattern: the transition from child to adult passport involves a jump in cost (from £66.50 to £88.50) and a stricter identity verification process. For a 16-year-old who has held a child passport for 5 years, this is essentially starting fresh with adult documentation requirements.

“You can apply to renew a child passport online or by post. If your child’s passport has expired, you must renew it before they can travel.”

GOV.UK (official passport guidance)

“What you need: your child’s current passport (actual document, not a photocopy), proof of any changes, parent’s passport details.”

Post Office (renewal checklist)

The pattern across these rules: renewal is simpler than a first application, consent is the biggest variable for separated families, and planning for the age-16 transition avoids a last-minute adult passport rush. For a UK parent, the most efficient route is online renewal at £66.50, submitted at least 3 weeks before travel, with all parental details confirmed upfront.
