Pet Passport vs Animal Health Certificate — what changed after Brexit?
Before January 2021, a single EU Pet Passport covered travel between the UK and Europe. Brexit split the system in two — and the wrong paperwork will get you turned away at the border.
Quick answer
- Travelling between EU/EEA countries: EU Pet Passport — multi-trip, no expiry.
- Travelling from the EU to Great Britain: Animal Health Certificate (AHC) — single-trip, issued within 10 days of travel.
- Travelling from Great Britain to the EU: Animal Health Certificate (AHC) — single-trip, issued within 10 days of travel.
- Northern Ireland: follows EU rules — EU Pet Passport accepted.
What is an EU Pet Passport?
An EU Pet Passport is a small blue booklet that records your pet's microchip, rabies vaccinations, and any other treatments like tapeworm. Your vet issues it once and updates it as boosters are given — it stays valid for the life of the animal as long as rabies jabs don't lapse.
It covers travel between any EU and EEA countries — take your dog from France to Spain, or the Netherlands to Austria — without needing new paperwork each time.
What is an Animal Health Certificate?
An Animal Health Certificate (AHC) is a single-use veterinary document. It covers one trip and must be issued by an official vet — not just any vet — within 10 days of travel. It covers the same ground as the passport (microchip, rabies, tapeworm) but you get a fresh one signed for each journey. You cannot reuse a previous AHC.
What changed after Brexit?
While the UK was in the EU, a single pet passport worked everywhere. After Brexit, Great Britain (England, Scotland, and Wales) dropped out of the scheme entirely, and two things broke:
- EU Pet Passports are no longer accepted for entry into Great Britain. Every trip from the EU to Great Britain now requires a fresh AHC.
- UK-issued pet passports are no longer valid in the EU. Pets travelling from Great Britain to the EU also need an AHC issued in Great Britain.
The change is one-directional for Northern Ireland: under the Windsor Framework, Northern Ireland continues to follow EU pet travel rules. EU Pet Passports remain valid for travel to and from Northern Ireland.
Common mistake: Assuming an old UK-issued EU Pet Passport still works. If it was issued in Great Britain before 2021, it is no longer valid for EU travel. You need an AHC instead.
Side-by-side comparison
| EU Pet Passport | Animal Health Certificate | |
|---|---|---|
| Valid for | EU/EEA travel | Travel to/from Great Britain |
| Trips covered | Unlimited (multi-trip) | Single trip |
| Issued by | Any authorised vet | Official (government-accredited) vet only |
| Timing | Any time (no expiry) | Within 10 days of travel |
| Cost | One-off (typically £50-80) | Per trip (typically £100-200+) |
| Return journey | Same passport | Can be endorsed for return within 4 months |
The 10-day rule for AHCs
An AHC must be issued no more than 10 days before you travel. In practice, that means booking your vet appointment close to departure — and official vets fill up fast during summer. If you can't get an appointment in time, you can't legally travel with your pet.
Not every practice can issue AHCs either. In the EU, only officially designated vets can sign one. In Great Britain, the vet must be authorised by APHA. Ask your practice before booking.
The 4-month return journey rule
Good news for the return leg: a GB vet can endorse your existing AHC for the journey back to the EU, as long as you return within 4 months of the original issue date. That saves you a second certificate and another vet bill. Stay longer than 4 months, though, and you'll need a new AHC issued in Great Britain.
Tip: For frequent travellers between the UK and EU, the cost of AHCs adds up quickly — £100-200 per trip. Some owners time their trips to use the 4-month return endorsement, reducing the number of full AHCs needed per year.
Which document do I need?
It depends on where you're going:
- EU country to EU country (e.g. France to Spain) — EU Pet Passport.
- EU country to Great Britain (e.g. France to England) — AHC issued by an official vet in the EU departure country.
- Great Britain to EU country (e.g. England to France) — AHC issued by an APHA-authorised vet in Great Britain.
- Great Britain to Northern Ireland — simplified process under the Windsor Framework; check current DAERA guidance.
- Any country to Northern Ireland — EU Pet Passport (Northern Ireland follows EU rules).
What about the proposed UK-EU pet passport scheme?
In May 2025, the UK and EU agreed in principle to negotiate a new pet travel agreement. If it goes through, it would bring back a multi-trip document for UK-EU travel — less paperwork, lower cost.
As of April 2026, nothing has been implemented yet. The AHC requirement remains in force. We'll update this guide when the new rules land.
Other requirements still apply
Whichever document you use, the health requirements are identical:
- Microchip — ISO-compliant, implanted before or on the same day as the first rabies vaccination.
- Rabies vaccination — 21-day wait after a primary vaccine; no wait for on-time boosters.
- Tapeworm treatment — required for Great Britain, Ireland, Finland, Norway, and Malta. Must be administered 24-120 hours before arrival.
Same rules, different paperwork.
