EquiDiaryHorse passports and microchipping in the UK: what is actually required
Last checked: 5 August 2026
A passport and a microchip are two separate legal obligations, an imported horse starts a 30-day clock the day it lands, and the food-chain declaration is the one page in the document you can never take back.
This page summarises published regulations and is not legal advice. It covers the UK. Rules elsewhere differ — Spain, France and Germany each run their own register, and the links at the foot of the page go to those versions.
Two things are compulsory, and they are not the same thing
A passport and a microchip are separate obligations that people routinely collapse into one. Every equine in the UK must have a passport from a passport issuing organisation, and every equine must be microchipped — including the older horses that were exempt for years. The microchip is what ties the document to the animal in front of you; without it a passport is a piece of paper that could belong to any horse.
| Obligation | When |
|---|---|
| Microchipping, England | compulsory since 1 October 2020, all ages |
| Microchipping, Wales | compulsory since 12 February 2021 |
| Microchipping, Scotland | compulsory since 28 March 2021 |
| Central Equine Database | every equine living in the UK must be recorded on it |
| Horse imported into the UK | register with a UK passport issuing organisation within 30 days |
| Failing to comply | fine of up to £5,000 |
The import rule is the one people miss
A horse arriving from abroad with a perfectly valid foreign passport is not finished. It has to be registered with a UK passport issuing organisation within 30 days of arrival so it lands on the Central Equine Database. This catches out buyers constantly: the paperwork looks complete, the horse is in the country, and the clock is already running.
The food-chain page, and why it is a one-way door
The passport carries a declaration about whether the horse is intended for human consumption. Its practical function has nothing to do with anyone's plans for the horse and everything to do with medicines: certain drugs may only be given to a horse signed out of the food chain, and a vet has to check the passport before treating. The declaration cannot be undone. Sign the horse out and it stays out — which is usually the right answer for a competition or leisure horse, but it is a decision, not a formality.
Practical consequence. If the passport is not to hand when the vet arrives, the treatment options narrow. That is the single best argument for keeping a photograph of the relevant pages somewhere you can reach from a phone.
When ownership changes
The passport goes with the horse, not with the seller — it is the horse's document. The new keeper needs to inform the passport issuing organisation so the record follows the animal. Ask to see the passport before money changes hands, check the microchip is readable and that its number matches the document, and check the silhouette and markings actually describe the horse in front of you.
What to keep, beyond the passport itself
The passport is the legal document, but it is rarely the only paper that matters when something goes wrong: the purchase invoice, the vetting report, insurance documents, loan or livery agreements, and any breed registration. These are the papers people hunt for at the worst possible moment.
Where EquiDiary fits
The wallet on each horse holds the papers that belong to the horse rather than to any single entry — passport pages, breed registration, insurance, the purchase invoice. Everyone the horse is shared with can open them, which is the point: the vet at 6am does not need to phone you to find out the horse's food-chain status. Only the owner can add or remove them.
