Animal Health Certificate (AHC): The 2026 UK Guide

If you live in Great Britain and you want to take your dog, cat or ferret to the EU, you need an Animal Health Certificate (AHC). GB-issued EU pet passports stopped being valid for GB→EU pet travel on 1 January 2021, at the end of the Brexit transition period. As of 22 April 2026, the rules tightened further — EU-issued pet passports held by GB residents, the loophole some people used by obtaining a passport from a vet while abroad, are no longer valid either. The AHC is now the only document that works. This guide covers what it is, why you need one, how to get one, where people get caught out, and what it costs.

What is an Animal Health Certificate? #

An Animal Health Certificate (AHC) is the official document a Great Britain resident needs to take a dog, cat or ferret into the EU, plus Switzerland and Norway. It replaced the UK pet passport scheme after Brexit. Each AHC is single-use, must be issued by an Official Veterinarian, and can cover up to 5 pets travelling together. From 22 April 2026, this 5-pet cap also applies per private vehicle for non-commercial entry into the EU, not just per owner. Travelling to Northern Ireland only no longer needs an AHC — a free Northern Ireland Pet Travel Document is enough — but an AHC is still required if you're carrying on from NI to the Republic of Ireland or any other EU country.

The AHC is more substantial than the name suggests. It runs to 9 to 12 pages of A4, manually struck-out and stamped, with each page signed and initialled in different-coloured ink from the printer. The Veterinary Defence Society — the body that insures UK vets against errors — describes it as one of the most exacting bits of paperwork in routine veterinary practice.

A few defining features worth knowing:

• Only an Official Veterinarian (OV) — a vet with extra APHA training and registration — can issue one.
• One AHC covers up to 5 pets, provided they're owned by the same person and travelling together for non-commercial purposes. From 22 April 2026, this 5-pet limit also applies per private vehicle entering the EU, not just per owner.
• It's single-use. Every trip from GB to the EU needs a fresh one.

One clarification worth making early. An AHC is not an EU pet passport — EU pet passports are issued to EU residents only, a rule that's been in force since well before Brexit. (What Brexit changed was that GB residents lost a different document, the old UK pet passport, on 1 January 2021.) It's also not the Northern Ireland Pet Travel Document, which is a separate, free, lifetime-valid scheme launched on 4 June 2025. Three different documents, three different uses.

Why do you need one? #

Without an AHC, a Great Britain resident can't legally take a pet into the EU. Border officials will check pet documentation on arrival, and refusals are immediate. If the paperwork isn't right, a pet may be quarantined, returned to Great Britain at your expense, or held for further action.

The AHC also matters once you've arrived. After EU entry, it remains valid for onward travel within the EU and for re-entry to GB for 6 months, as confirmed in GOV.UK's 21/04/2026 announcement and verified directly with APHA. Worth noting if you look this up yourself: the GOV.UK operational guidance page still says 4 months at the time of writing. The news announcement is more recent and reflects the rule change that took effect on 22/04/2026 — APHA confirmed by phone that 6 months is the current rule.

How do you get an AHC? #

Getting an AHC is a sequence of fixed steps in a fixed order: microchip first, then rabies vaccination, then a 21-day wait, then an OV appointment to issue the certificate within 10 days of EU entry. Dogs going to certain countries also need a tapeworm treatment 24–120 hours before arrival. If your pet's already chipped and vaccinated, allow 1–2 weeks. From scratch, allow at least 5–6 weeks.

Step 1 — Microchip the pet. The chip must be ISO 11784/11785 compliant. If your pet's already chipped, the OV will scan it on the day of the AHC appointment to confirm it's working and matches the records. The microchip has to be in place before the rabies vaccination — not at the same time, before.

Step 2 — Rabies vaccination. Any registered vet can administer this; it doesn't have to be an OV. The pet must be at least 12 weeks old. The vaccine must be inactivated or recombinant, and approved in the country it's given in. Make sure the vet records the microchip number on the vaccination certificate.

Step 3 — Wait at least 21 full days. Day 1 is the day after the vaccination. A vaccine given on 1 June means the earliest possible travel date is 23 June. Where a vaccine's manufacturer datasheet specifies a longer onset of immunity (sometimes 30 days), the OV must respect that longer period — ask the vet which product was used and confirm the wait.

There's one important wrinkle here. The 21-day wait only applies to a primary vaccination. Boosters don't need a wait — but only if the booster was given before the previous vaccine expired. If the previous one had lapsed even by a day, the booster counts as a fresh primary and the 21-day clock starts again.

Step 4 — Book an OV appointment. Most practices need 1–3 weeks' notice. Short-notice appointments (under 7 days) are available from specialist services but typically cost £100 more.

You'll need to bring:

• Proof of microchipping date
• Proof of rabies vaccination (card, certificate, previous pet passport, or vet clinical history)
• Travel dates and destination country
• Details of any additional pets going on the same AHC

Step 5 — AHC issued. The OV checks the microchip against the records, confirms the rabies vaccination is in date and was given after microchipping, and completes the certificate. The AHC must be issued within 10 days of your pet entering the EU — not departing the UK, not check-in. Entering. Day 1 is the date of issue.

Step 6 — Tapeworm treatment (dogs only, certain destinations only). If you're travelling to Finland, Ireland, Malta, Northern Ireland or Norway, your dog needs tapeworm treatment administered by a vet between 24 and 120 hours (1 to 5 days) before arrival.

A few practical points worth flagging because the timing trips people up:

• The treatment has to be given by a vet, not by you at home.
• The vet records it in the AHC at the time of treatment — so this is usually a UK vet visit a day or two before you travel, not something done on arrival.
• It doesn't have to be the same OV who issued your AHC. Any registered vet can administer the treatment and record it in the certificate.
• For most people driving to one of these countries, the simplest move is to time the OV appointment for the AHC and the tapeworm treatment to be the same visit. Just make sure you'll arrive in-country within 120 hours of that appointment.

Step 7 — Enter the EU through a designated Travellers' Point of Entry. Documentation and microchip may be checked on arrival.

What about coming home? #

For the return leg to Great Britain, all dogs need tapeworm treatment administered by a vet 24–120 hours before re-entering GB — except dogs returning from Finland, Ireland, Malta, Northern Ireland or Norway, where the outbound treatment also covers the return if you're back within 5 days. The treatment must be given by a vet abroad and recorded in your AHC. Cats and ferrets don't need this.

A few things to know:

• The return treatment is given by a vet in the country you're coming back from, not in the UK before you leave.
• The same 24–120 hour window applies. Treatment given on Monday afternoon means you can re-enter GB between Tuesday afternoon and Saturday afternoon.

• Book the vet appointment abroad in advance. Finding an open vet in a holiday town on a Sunday is its own adventure.

Where do people get caught out? #

The rules have a lot of moving parts and small caveats. It's easy to get tripped up. Here's where it happens most often.

Microchipping after rabies vaccination. If the microchip was implanted, or first scanned and recorded, after the rabies vaccination, the vaccine is invalid for travel. The whole sequence resets: chip, then re-vaccinate, then wait 21 days. Vets sometimes catch this on the day of the AHC appointment — at which point the trip is off.

The expired-by-one-day booster. A rabies booster only counts as a booster if it's given before the previous vaccination expired. One day late and it counts as a fresh primary, with a fresh 21-day wait.

Misunderstanding the 10-day window. The 10 days runs from the date the AHC is issued to the date your pet enters the EU. Not departure. Not check-in. Entry. A slow ferry, a layover, an overnight stop in transit — all of it eats into the window.

Booking a vet who isn't an OV. Not every practice has an Official Veterinarian, and OVs are often shared across multiple branches. People book "an appointment for the pet travel paperwork", turn up, and discover the practice can't issue an AHC that day.

Missing supporting documents. OVs are supposed to append certified copies of the microchip and vaccination records they relied on. When this gets skipped, the AHC arrives at the border on its own and the border official won't accept it.

Tapeworm timing miscalculated. For dogs going to Finland, Ireland, Malta, Northern Ireland or Norway: treatment given less than 24 hours before arrival, or more than 120 hours before, invalidates the AHC for that destination.

How much does an Animal Health Certificate cost? #

An AHC costs roughly £80–£110 from specialist AHC-only services, and £150–£250+ from standard high-street vet practices (London Vet Clinic, for instance, publishes £232 inclusive of VAT for one pet). Prices creep up further for peak-season appointments or anything booked at short notice. Additional pets on the same certificate typically add £30–£75 each. Rabies vaccinations and tapeworm treatments are billed separately.

Costs beyond the AHC itself
