About microchipping

If your pet should go missing, microchipping is a great way to ensure that the best efforts are made to reunite you with your pet. However, microchipping can only be effective if pet keepers remember to keep their contact details up to date, which is also a requirement by law. Please visit The Microchipping of Cats and Dogs (England) Regulations 2023 for further details.

Any changes to a keeper’s contact details must be updated on their microchip database to ensure compliance with the law. If a dog keeper subsequently moves, or changes their contact telephone number, etc. then the dog is no longer considered microchipped under the new law and enforcement can be taken.

What is the law around microchipping?

As of 6 April 2016, it is compulsory that all dogs in England, Scotland and Wales are microchipped.

Further as of the Government's declaration on 13 March 2023, it is now mandatory for all cats in England to be microchipped by 10 June 2024 and their contact details stored and kept up to date on a pet microchipping database.  Find out more on the latest law that surrounds dog and cat microchipping here.


Did you know it is also law to have a dog ID tag?

Thousands of pets go missing each year, and a lot of those are never returned to their keepers because their details are not up to date on a microchip database and they have no other form of identification (e.g. pet identification tags).

The Control of Dogs Order 1992 mandates that any dog in a public place must wear a collar with the name and address (including postcode) of the owner engraved or written on it, or engraved on a tag. Your telephone number is optional (but advisable).

You can be fined £5000 if your dog does not wear an identification tag.

How does a microchip help to reunite a lost pet with their keeper?

Once your pet is microchipped, you and your pet's details are stored in a microchip database along with the microchip's unique 15 digit code.

When a missing pet is found, an animal professional (for example a vet or dog warden) will scan the pet revealing the microchip's unique 15 digit code, and contact the microchip database your pet is recorded with. The customer care staff will perform some security checks before releasing your contact details to the animal professional, so that your pet can be reunited with you.
