TL;DR
- In 2026 a child British passport renewal costs GBP 57.50 online via gov.uk/get-a-child-passport, or GBP 69 by postal Form C1. The renewed book stays valid for 5 years.
- Both parents (or all people with parental responsibility) must consent for any child under 16. A single-parent applicant must supply a court order or death certificate to override the missing signature.
- A countersignatory is not required for a child renewal. The countersignatory rule applies only to a first child passport.
- Standard processing is 3 weeks from the moment HMPO confirms receipt of documents. The 1-day Premium service became available for child renewals after the HMPO appointment-system consolidation in early 2025; Fast Track remains a 1-week postal option.
- From late 2024 second and subsequent child renewals can be filed entirely online through HMPO's digital service, with no need to post the expiring passport for most applicants meeting the photo and biometric checks.
The 2026 fee and the online channel at gov.uk/get-a-child-passport
A child British passport renewal lodged in 2026 attracts the HM Passport Office fee of GBP 57.50 when filed through the online service at gov.uk/get-a-child-passport, or GBP 69 if filed by post on Form C1. Overseas child renewals are charged at GBP 73.50 online. These figures reflect the 7 percent uplift confirmed by HMPO on 11 April 2025 and held through the 2026 fee schedule. The renewed passport carries a 5-year validity, not the 10-year adult validity, because facial growth between the ages of 5 and 11 forces a more frequent biometric refresh.
The online route is the default channel published by GOV.UK and the one HMPO actively encourages. A parent or person with parental responsibility creates the application against their own GOV.UK identity, uploads a digital photo that meets the HMPO photo guide, and pays by card. The system issues a reference number on submission and a tracking link by email.
Postal renewals continue to exist for households without a card payment method or where the digital photo will not pass automated checks. The C1 paper form is requested from the GOV.UK passport pages or collected from Post Office branches operating the Check and Send service.
Documents and parental consent rules under the British Nationality Act framework
The standard renewal bundle consists of the expiring child passport, a digital photo (or two printed photos for postal), evidence of any change of name (a deed poll, marriage certificate of a parent, or court order), and the parental consent record. The British Nationality Act 1981 sets the citizenship basis on which the passport is issued; HMPO operational guidance, published in the 2026 Passport Office customer service standards, sets the procedural rules below that.
Where the child is under 16, both parents (or all holders of parental responsibility) must consent. The online application captures the consenting parent's confirmation, and the second parent receives an email link to confirm separately. If a second parent is unreachable, the applicant submits a court order granting sole parental responsibility, a death certificate, or written explanation that HMPO reviews case by case.
A countersignatory, the rule that trips up many first-time child applicants, is not required for a child renewal. That requirement applies only to a first British passport for a child. For a renewal where a previous valid passport exists, HMPO's identity confirmation comes from the previous book and biometric matching.
Processing time, Premium 1-day and Fast Track 1-week
Standard processing in 2026 runs to 3 weeks from the date HMPO confirms it has every document it needs. That clock starts at the receipt confirmation email, not at submission. Applications with missing information are paused and the 3-week count restarts when the missing piece arrives.
For families travelling sooner, two paid-uplift services exist. The Premium 1-day service costs GBP 207.50 in 2026 and requires an in-person appointment at one of the seven HMPO regional offices. The Fast Track service runs at GBP 178 and delivers a new passport within one week, with the application lodged at a Post Office Check and Send counter or, in 2026, via the consolidated digital appointment portal. Both services became available for child renewals after the HMPO appointment-system consolidation in early 2025, where previously only adult renewals could use Premium in person.
Shared custody, cross-border parents and changes of name
Custody and cross-border arrangements frequently complicate child renewals. Where a court order regulates which parent holds the passport, HMPO will accept a copy of the order with the application and contact the other parent to confirm consent. Where one parent lives overseas, a scanned consent signed before a notary or solicitor is accepted in place of the digital consent click.
A change of child name (after a parent remarries, after a deed poll, or after adoption) must be evidenced by the matching legal document. A marriage certificate of the parent does not automatically change the child's name. A deed poll signed by both parents, or a court order under section 1 of the Children Act 1989, is the typical route.
What this means in practice: a child born in 2019 holding a UK passport issued in 2021 will see that passport expire in 2026. If the parents separated in 2024 and a child arrangements order names one parent as primary carer, that parent submits the online renewal, the second parent confirms by email link, and HMPO releases the new passport within 3 weeks at the standard fee of GBP 57.50.
The 2026 update: the HMPO digital service and end-to-end online renewals
From late 2024 HMPO extended its digital passport service so that second and subsequent child renewals can run entirely online, without the need to post the expiring passport back to HMPO. The system performs biometric matching against the previous passport image already on file. The expiring passport is then cancelled in the database and the family is told to destroy it by cutting through the cover at the corner.
The end-to-end online flow applies where the child's previous passport was issued under the current biometric standard (passports issued from 2010 onward), the photo passes automated checks, and no name change is being notified. Applications with name changes or first passports continue to require postal return of evidence.
Overseas child renewal, lost or stolen and refusal rights
Children whose families live outside the UK renew through the same gov.uk service. The 2026 overseas fee is GBP 73.50 online and the processing route is HMPO Liverpool, which handles all overseas applications. Delivery is by courier and adds the carrier's tariff to the headline fee. There is no British Embassy passport-issuing function in 2026; embassies refer applicants back to GOV.UK.
Lost or stolen child passports require a separate LS01 declaration before the renewal can proceed, alongside the standard renewal documents. The renewal fee is unchanged. Refusal of a child passport is rare but possible where HMPO suspects the application is contested by another parent; the refusal carries a reconsideration route through the HMPO complaints process and, ultimately, judicial review.
Photo standards, biometric refresh and common rejection reasons
The single biggest cause of renewal delay in 2026 is a non-compliant photo. The HMPO photo guide sets specific rules: a plain cream or light-grey background, eyes open and looking at the camera, mouth closed, no hair across the eyes, no shadows on the face or behind the head, and no glasses (a 2016 rule that remains in force). The HMPO online photo upload tool runs an automated compliance check before the application can be submitted, but borderline photos can still be flagged later in casework.
For very young children the photo rules are slightly relaxed. Babies under 12 months can be photographed lying on a plain white sheet with their eyes open where possible. The mouth-closed rule is waived. Hands must not be visible in the frame. Many parents use a high-street photo booth's child setting or a professional photographer rather than attempt the self-capture route, where the automated checker tends to reject phone-camera images of young children.
Other common rejection reasons for child renewals are missing parental consent (the second parent failed to click the email link within the 14-day window), an outdated change-of-name evidence file (a deed poll without both parents' signatures, or a marriage certificate where the child was not formally renamed), and a digital photo file that does not meet the HMPO size and resolution requirements (between 750 and 10,000 pixels in width, JPEG format, file size 3MB or less).
Notifying HMPO of changes and the cancellation of the old book
Renewal applications do not automatically update HMPO's wider records. A change of address is captured at application but the family's GOV.UK account remains the primary contact channel; HMPO uses the application email for case correspondence. Where a parent has changed name since the previous child passport was issued, that change is recorded in the application but the parent does not need a separate notification.
The old child passport is cancelled in the HMPO database at the point the new book is issued. Families are asked to destroy the old book by cutting through the corner of the cover, taking care to leave personal data unreadable. The old book should not be retained for travel or photo-ID use after cancellation; airline check-in systems flag cancelled passports against the IATA Timatic database.

How we verified this
Figures and process steps were cross-checked in May 2026 against the GOV.UK child passport page at gov.uk/get-a-child-passport, the HMPO fee schedule published on 11 April 2025, and the HMPO customer service standards covering processing times. Parental consent rules were checked against the British Nationality Act 1981 framework and HMPO operational guidance on child passport applications. The digital renewal extension was verified through the HMPO digital service announcement from late 2024 and the consolidated appointment booking system rolled out in early 2025. Only primary GOV.UK and HMPO sources were used.

Frequently asked questions
How much does it cost to renew a child's British passport in 2026?
The 2026 online renewal fee is GBP 57.50. The postal fee is GBP 69. Overseas online renewals are GBP 73.50. These figures reflect the HMPO uplift of 11 April 2025 and apply to all child renewals between birth and the day before the child's 16th birthday.
Does a child passport renewal need a countersignatory?
No. A countersignatory is required only for a first child passport, not for a renewal. HMPO verifies identity against the existing passport on file. Where the child's name has changed since the last passport, supporting documents (deed poll, court order) are required but a countersignatory is still not part of the bundle.
Can one parent renew a child passport without the other parent's consent?
Not by default. Both parents or all holders of parental responsibility must consent for applicants under 16. Where a second parent is unreachable, deceased, or where a court has restricted their parental responsibility, the consenting parent provides a court order, death certificate, or written explanation for HMPO to consider.
How long does a child British passport last once renewed?
A child British passport is valid for 5 years from the date of issue. This is shorter than the 10-year adult passport because the child's appearance and biometric markers change rapidly. The renewed passport must be replaced again before its 5-year expiry.
Is the 1-day Premium service available for a child renewal?
Yes, since the HMPO appointment-system update in early 2025 the 1-day Premium service is available for child renewals at GBP 207.50, by appointment at one of the seven regional offices. Fast Track at GBP 178 is also available. Both options must be booked through the consolidated GOV.UK booking portal.
