Applying for British Passport: Post-Ceremony Checklist

You’ve taken the oath, held your certificate, and celebrated—congratulations. Now the clock starts. This guide shows exactly what to do after your ceremony, with applying for a British passport at the centre of a simple, time-based plan.

Below you’ll find a day-by-day checklist, eligibility and documents, photo and countersignature rules, application routes, fees and timelines, special scenarios, and common pitfalls—plus a helpful app to share with anyone still preparing for settlement or citizenship.

From oath to passport: what to do after your citizenship ceremony

Here’s a clear, time-based checklist of what to do straight away after you become a British citizen. Prioritise safeguarding your certificate, returning your BRP, and starting your passport application.

Day 0 to Day 5: immediate steps you should not miss

Protect your naturalisation certificate immediately. Store it flat in a protective sleeve. HM Passport Office (HMPO) will need the original; do not laminate it.
Return your BRP within 5 working days. The Home Office requires you to send your biometric residence permit back within 5 working days of getting your certificate or you can be fined up to £1,000. See the official guidance on what to do after citizenship and BRP return for the address and instructions.
Start your first adult passport application. Beginning now shortens your wait. Decide your route (online, Post Office Digital Check and Send, or paper).
Don’t book travel yet. Wait until your passport is in your hand. If you later secure urgent travel, explore Fast Track or an emergency travel document where eligible.
Capture your identity details while they’re fresh. Note any recent name changes and collect supporting evidence (deed poll, marriage certificate).

Week 1: documents, photos, countersignature and planning

Gather originals: naturalisation certificate, evidence of identity and name, and any previous passports. HMPO requires originals, and certified translations if not in English or Welsh.
Get compliant digital photos: follow UK passport photo requirements—neutral expression, plain light background, correct size/cropping, no heavy glare on glasses.
Line up a countersignatory: For a first adult passport, you usually need someone in an eligible profession who has known you for at least 2 years and can confirm your identity. For paper applications they sign the back of one photo; for online they’ll confirm digitally.
Create a scan checklist: If you apply online, you’ll upload a photo and input details. Keep a tidy folder with copies for your records (you still send originals when required).

Week 2 and beyond: tracking and travel timing

Set realistic timelines: HMPO says not to book travel until you receive your passport. Standard applications can take weeks, and checks for first-time applicants can be longer.
Track and respond fast: Use your application reference to follow progress. If HMPO requests extra documents or an interview, reply quickly to avoid delays.
Plan travel only after delivery: Once your passport arrives, use it to enter the UK—your BRP or certificate cannot be used to enter the UK once you have a British passport.

Can I apply for my British passport right away

Yes—once you’ve become a citizen and have your certificate, you can apply for your first adult British passport. The naturalisation certificate is your proof of citizenship.

Proof of citizenship: naturalisation certificate essentials

Definition: Your naturalisation certificate is the official proof you are a British citizen. HMPO will require the original and will return it after checks. Keep it flat, unlaminated, and safe until it comes back.

BRP return rules and how they affect your application

You must send your BRP back to the Home Office within 5 working days of getting your certificate. This is separate from the passport process, but the legal duty and potential fine still apply. Returning your BRP on time helps prevent record conflicts while HMPO verifies your status.

Name changes and timing around ceremonies and marriages

Applying in a new name: If you changed your name due to marriage, deed poll or another reason, apply in that name and send the original evidence (for example, marriage certificate or enrolled deed poll).
Applying in your old name: If you haven’t updated other records yet, you may apply in your current legal name as shown on your evidence. Ensure consistency across documents to prevent manual checks.
Recently married? Consider whether to update your bank, GP, HMRC and DVLA to match your passport details soon after you receive it.

Documents you need for a first adult British passport

Send originals, not photocopies. If a document is not in English or Welsh, include a certified translation. HMPO can request more evidence if needed.

Core documents checklist

Naturalisation certificate (original)
Evidence of identity and name (for example, UK or foreign passport, biometric ID, or government-issued photo ID if available)
Proof of any name change (marriage certificate, deed poll, divorce decree absolute with name change)
Any previous passports you hold (including foreign passports if requested)
Two recent identical photos if applying by paper; compliant digital photo or code if applying online
Proof of address if requested (utility bill, bank statement, council tax, etc.)

Evidence for name, date of birth and identity

Name: marriage certificate, deed poll, adoption order, or other official documents showing your legal name.
Date of birth: birth certificate (full version for those born on/after 1 January 1983 when relevant), adoption certificate, or other official record.
Identity: passports (current and expired), government-issued photo ID. Dual nationals may be asked to provide colour copies of their non‑UK passport, including all pages, in some cases.
Translations: provide certified translations for documents not in English or Welsh.

If HMPO asks for more information

It’s normal for first-time applicants to face extra checks. Respond promptly to any request, which may include:

Additional evidence of identity or residence history
Copies of foreign passports (all pages), especially if you hold dual nationality
An interview appointment to confirm your identity

Photos and countersignature done right

Two of the most common rejection reasons are non-compliant photos and countersignature errors. Get these right first time.

Digital photo standards and getting a photo code

Background: plain, light-coloured background with no patterns or shadows.
Lighting and expression: even lighting, neutral expression, mouth closed, eyes open, face fully visible.
Glasses: allowed if no glare or heavy frames obscuring the eyes; no sunglasses or tinted lenses.
Quality: sharp focus, no filters, no retouching. Use a compliant provider that gives a photo code for easy upload.

Who can countersign your first passport

Countersignatory (definition): an adult in a recognised profession who has known you personally for at least 2 years and is not related to you. They confirm your identity to HMPO. For paper applications they complete Section 10 and sign the back of one photo; online, they confirm digitally.

Typical eligible professions include teachers, accountants, engineers, nurses, civil servants, and other regulated roles. They should not live at your address, be related, or be involved in your application as an agent.

Remote countersignatures and digital applications

Online applications invite your referee via email to confirm your identity and how long they’ve known you. Ensure their contact details are accurate; delayed responses can stall your application.

Choose your application route

Pick the route that balances speed, accuracy, and support.

Online application: speed and convenience

Usually the fastest and cheapest route.
Upload a compliant digital photo or use a photo code.
Pay fees online; keep your application reference safe to track progress.

Post Office Digital Check and Send

In-branch support that reduces errors for first-time applicants.
Staff check your photos and details and submit digitally on your behalf.
Good balance of guidance and speed if you’re unsure about photo/countersignature rules.

Paper forms: when and why to use them

Use if your circumstances are complex or if advised by HMPO.
Costs are typically higher and processing can be slower than online.
Make sure your countersignatory completes Section 10 and signs one photo; write clearly to avoid transcription mistakes.

Fees, timing and tracking in 2025

Fees and processing times change, so always check the latest government guidance before applying or travelling.

Current fees and delivery

Online vs paper: Online applications are usually cheaper than paper. Government guidance for paper applications cites a higher fee, and posted applications take longer than online.
Priority services: 1 Week Fast Track and Premium services have higher fees and limited eligibility. First adult passports are generally not eligible for Online Premium, and 1 Week Fast Track availability for first adult passports is limited—always check current rules.
Delivery: Your new passport is typically delivered by secure courier; keep your address and contact details up to date.

How long it really takes

Official guidance: Do not book travel until you have your passport in hand. First-time applications can take several weeks depending on checks.
Set expectations: Start early, answer HMPO queries quickly, and ensure photos and countersignatures meet the rules to avoid resets.

Tracking updates and contact options

Use your application reference to track progress and get status emails or texts.
If HMPO requests more evidence or an interview, respond promptly.
Escalate only if you’ve exceeded guidance times or have urgent travel with evidence.

Special scenarios for new citizens

Dual citizenship and which passport to use

The UK allows dual citizenship. If you hold two passports, travel rules can vary by destination. Once you have a British passport, you must use it to enter the UK. Some applications, especially overseas, may require copies of your non‑UK passport—have these ready if requested.

Applying for a child passport after registering your child

If your child became British by registration (for example, born abroad or before you naturalised), complete registration first, then apply for their first child passport with original evidence of their status. Allow extra time for checks and countersignature.

Name mismatches across multiple passports

Keep identity data consistent across all passports and travel documents. Name mismatches can cause airline and border delays. If you changed your name, update relevant records and carry the original evidence (e.g., marriage certificate or deed poll) when travelling shortly after the change.

Common pitfalls and how to avoid them

Photo and countersignature rejections

Photo not meeting size, background or lighting rules; glasses glare; heavy filters or edits.
Countersignatory not eligible, related to you, or hasn’t known you for 2 years.
Online countersignatory slow to respond—brief them in advance.

Name and evidence mismatches

Different names across documents without supporting evidence.
Laminated or photocopied documents instead of originals.
Missing certified translations for non‑English/Welsh documents.

Travel booked too soon

Don’t book non‑refundable travel until your passport arrives.
For urgent travel, check if a Fast Track service or an emergency travel document fits your situation and eligibility.

Benefits of British citizenship your passport unlocks

Right of abode, no immigration controls

Your passport confirms your right of abode: you can live and work in the UK without visas or BRP conditions. Once you have a UK passport, use it to enter the UK.

Voting, jury service and civic participation

As a British citizen, you can vote in UK elections and may be called for jury service—new rights that reflect your place in civic life.

Travel flexibility and consular protection

Enjoy broad visa-free or visa-on-arrival access in many countries and access British consular assistance abroad. Always check entry rules for your destination in advance.

Quick FAQs for first-time applicants

Can I use premium or 1 week services for my first adult passport

Online Premium isn’t available for first adult passports. 1 Week Fast Track has limited eligibility and may not cover first adult passports—always check current HMPO guidance.

Will HMPO keep my naturalisation certificate

No—HMPO needs the original to check your status and will return it. Keep it unlaminated, flat and safe when posting and when it comes back.

Do I need to update employers, bank, and GP

Yes. After you receive your passport, update your employer, HMRC, bank, GP, DVLA, university and any professional bodies to align your name and nationality records.

Can I travel using my BRP or certificate after I become British

No. To travel outside the UK you need a British passport (or right of abode evidence). Once you have a UK passport, you must use it to enter the UK.

Do I send originals and translations

Yes. Send original documents, not photocopies, and include certified translations if a document isn’t in English or Welsh.
