Renewing your child’s British passport doesn’t have to be complicated. But if you get the steps wrong then you will face delays or rejections. And the process of your child’s British passport renewal is different from renewing an adult passport.
For renewing your child’s passport you need specific documents, particular photos and sometimes extra paperwork depending on your child’s age. And by any chance if you miss even one requirement then your application can get sent back. That’s why you need to follow the correct steps.
Do you want to know the process step-by-step? Read ahead.
When Does Your Child’s Passport Need Renewal?
Your child’s British passport is valid for five years and not ten years like an adult passport. That’s why renewal is required once the passport expires or when your child turns 16.
Ages Rules That You Should Not Miss
If your child’s passport was issued before they were 16 then it cannot be extended. And a new adult passport is required after your child turns 16.
Expiry vs Travel Validity
Many countries require at least six months validity to travel. Even if your child’s passport has not expired, renewal may still be necessary before departure.

Eligibility Rules You Must Check First
Before starting the British passport application from Australia you should confirm that:
- Your child holds British citizenship.
- Parental responsibility is clearly established.
- No name or nationality changes are pending for your child.
And if the details have changed since the last passport then extra documents may be required with your British passport application from Australia.
Documents You’ll Need for Your Child’s Passport Renewal
If you have all the documents ready before you apply for a UK passport renewal then it reduces a lot of stress.
Mandatory Documents
- Current or expired passport of your child
- Birth certificate showing parent details
- Proof of parental responsibility
Additional Documents That May be Required
- Court orders or adoption papers
- Evidence of name changes
- Parent certification
You should always send your original documents to apply for a UK passport unless you’re instructed otherwise.
Step-by-step Process to Renew Your Child’s British Passport
This is where most applications succeed or fail. Because following the steps in order and understanding what UK authorities actually look for makes a huge difference to processing time.
Step 1: Apply With the Help of Global British Passport
- You can submit your child’s British passport renewal through Global British Passport for expert guidance. Our team will guide you through confirming your child’s personal details, passport information and your parental responsibilities.
We will help you get everything right the first time. Because even the smallest spelling errors or mismatched details can trigger manual reviews later. So our team will make sure your names, date of birth and parental information match the existing passport details.
Step 2: Upload a Compliant Photo
Photo rejection is one of the most common causes of delay. Because the image must meet the strict rules around lighting, background, head position and facial expression.
Also, you should avoid shadows, patterned backgrounds or casual photos taken in poor lighting. And if the system flags the image then replace it immediately rather than hoping for it to pass.
Step 3: Pay the Correct Fee
Once you submit the application then you’ll be prompted to pay the overseas renewal fee. And international applications cost more than UK renewals.
Also, the fees are non-refundable if the application is rejected. That’s why you should double-check that you are paying for a child’s British passport renewal and not an adult’s application.
Step 4: Send Supporting Documents
After payment, you’ll receive instructions on which documents must be posted. And you must send your original documents using tracked delivery and include everything in one package.
And delays often occur when documents arrive late, incomplete or without tracking. Plus, processing does not begin until all documents are received.

How Long Does a Child’s Passport Renewal Take?
From Australia, processing usually takes several weeks. And delays always occur during peak travel periods or if the documents you submitted are incomplete. That’s why you should submit your application early if you have travel planned. Because it allows you extra time even if any kind of delays happen.
