New laws surrounding equine identification came into force in England on 1 October.  Defra’s new equine identification regulations legally require every horse, pony and donkey to be microchipped and possess a valid UK passport, with details stored in the Central Equine Database.  All horses born after 30 June 2009 are already required to be microchipped. Owners of horses born before this date will have two years from today to get their equines microchipped.
