Microchip your pet
Microchipping Requirements in England
Under The Microchipping of Cats and Dogs (England) Regulations 2023, effective 10 June 2024, ALL owned dogs must be microchipped by 8 weeks old, and ALL owned cats by 20 weeks old. This requirement replaces the earlier Dogs‑only 2015 regulations and now includes cats.
The law applies to owned cats only—farm, rescue or feral cats with minimal human contact are exempt. Failure to microchip or register your pet properly can result in a fine of up to £500. Authorities may issue a compliance notice, giving you 21 days to act, after which the local council may implant a microchip at your expense.
Microchipping in Wales
In Wales, all dogs must be microchipped by 8 weeks old, under The Microchipping of Dogs (Wales) Regulations 2015.
Cats are not yet legally required to be microchipped. While strongly recommended for all pets, the Welsh Government has not yet extended mandatory cat microchipping.
Microchipping in Scotland
The Microchipping of Dogs (Scotland) Regulations 2016 mandates microchipping of all dogs by 8 weeks old. Breeders must implant and register microchips before transfer, and keeper must keep database details current.
As of April 2025, there is no obligation to microchip cats in Scotland; it remains optional/encouraged practice only.

Why Microchips & Database Registration Matter
- Reuniting lost pets: Microchipped pets are more than twice as likely to be returned to their keeper.
- Legal compliance: Omitting a microchip or not updating keeper's contact info is an offence, potentially leading to fines or prosecution.
- Exemptions: A veterinary surgeon may certify that microchipping adversely affects your pet’s health; such exemptions must follow specified templates.
