Understanding Baby Passports in the UK
If you are planning your first family holiday abroad, one thing that surprises many new parents is that babies need their own passport from birth. There is no minimum age requirement in the UK — your child can apply for a passport from day one. Whether your baby is three weeks or three months old, they will need a valid passport to travel internationally.
Knowing this early makes a real difference, because the application process for a child's first passport takes time and involves specific documents that can catch parents off guard. This guide explains exactly what you need, how the process works, and what to watch out for.
Who Is Eligible to Apply for a Baby Passport in the UK?
Any child who is a British citizen from birth is entitled to a UK passport. This includes children born in the UK to at least one parent who is a British citizen or settled in the UK, as well as children born abroad to a British parent in certain circumstances.
If there is any uncertainty about your child's entitlement to British citizenship — for example, if parents have different nationalities or if the father is not named on the birth certificate — additional documentation may be required. It is worth checking the official guidance on GOV.UK's child passport page before you begin your application, as eligibility rules can affect what you need to submit.
Parental consent is also a factor. In most cases, both parents with parental responsibility need to consent to the passport application. If circumstances are more complex — such as sole parental responsibility or a court order in place — you should review the official guidance carefully.
How to Apply for Your Baby's Passport: A Step-by-Step Guide
- Obtain your child's full birth certificate from the General Register Office. This is not the short version — you need the full certificate showing both parents' details. It costs £12.50 to order online and takes a few days to arrive.
- Find a suitable countersignatory. This must be someone who has known at least one parent for two or more years, works in a recognised profession, and can confirm the photo is a true likeness of your child.
- Take a compliant passport photo of your baby. Follow the official photo requirements carefully — see the photo tips section below.
- Complete the application online via GOV.UK or by post using form LS01. Online applications are generally faster and cheaper.
- Submit your application along with all required documents and pay the relevant fee. Keep your application reference number so you can track progress online.
Common Pitfalls to Avoid When Applying for a Baby Passport
The single most common mistake is submitting the short birth certificate instead of the full one. The short certificate only includes the child's name and date of birth. His Majesty's Passport Office (HMPO) requires the full certificate, which includes both parents' details and the registrar's signature. If you send the wrong one, your application will be returned and you will lose valuable time.
Another frequent issue is the countersignatory. Many parents assume a close family friend or relative will do, but the person must meet strict professional criteria. They cannot be a family member of the child or the parents. Confirming your countersignatory is eligible before you take the photos will save you from having to repeat the process.
Photo rejections are also very common for baby applications. The requirements are the same as for adult photos, and infants are understandably difficult to photograph correctly. A rejected photo means starting that part of the process again, which adds to your timeline.
Finally, do not underestimate how long the process takes. Standard processing times can be lengthy, particularly during busy periods such as spring and summer. Apply as soon as you have the birth certificate in hand if you have travel plans.
Required Documents and Fees
When applying for your baby's first UK passport, you will typically need the following:
- The child's full birth certificate (not the short version)
- A compliant passport photo, countersigned on the reverse
- Details of a suitable countersignatory
- Proof of the parents' nationality if relevant to the child's citizenship entitlement
- Payment of the application fee
As of the time of writing, the fee for a child passport is £53.50 for an online application or £62.50 for a postal application. A child passport is valid for five years, not the ten years that adult passports carry.
If you need your passport more quickly, HMPO offers an Urgent service that requires an in-person appointment at a passport office. The same-day Premium service is not available for first-time child applications.
Fees and processing options can change, so always check the current fees and requirements on the GOV.UK child passport page before submitting your application.
Tips for Getting the Baby Passport Photo Right
Passport photo requirements are the same for babies as they are for adults: plain cream or light grey background, no shadows, eyes open and clearly visible, mouth closed, and a neutral expression. The challenge is that most babies cannot sit unsupported, and no hands or arms can appear in the photo.
The most practical approach for very young babies is to lay them flat on a white or plain light-coloured sheet and photograph them from directly above, then crop the image tightly to the face. Chemist photo booths are not suitable for babies who cannot sit unaided. Some high street pharmacies such as Boots offer assisted photo services, which can work for babies around four to six months who can briefly hold their head up.
If you are unsure whether your photo meets the requirements, check the full technical specifications on the GOV.UK passport photo guidance page before printing or submitting anything.
How Private Assistance Can Simplify Your Baby's Passport Application
Applying for a baby's first passport involves more steps and more specific requirements than many parents expect. A missed document, an ineligible countersignatory, or a non-compliant photo can result in delays that are particularly stressful when you have travel plans in place.
A private passport assistance service can help you understand exactly what is required, review your documents before submission, and guide you through the process with confidence. While no private service can guarantee passport approval — that decision rests entirely with HMPO — having expert support can help you avoid common errors and submit a more complete application first time.
