Safety first
- If you're found to have an unchipped cat, you'll get 21 days to have it chipped or could face a fine of up to £500.
- Free-living cats with little or no human contact, such as farm, feral or community cats, aren't covered by the rule.
Step by step
-
Step 1: Check the rules where you live
In England, the law has required pet cats to be microchipped and registered on an approved database since 10 June 2024, by the time they're 20 weeks old. This includes cats that never go outside. In Scotland, Wales and Northern Ireland it isn't currently compulsory for cats, but it's still strongly recommended.

Step 2: Find out if your cat is already chipped
Cats from rescue centres are usually chipped before adoption. Ask for the chip number and database name. A vet can scan your cat to check.

Step 3: Book the appointment
Book with your vet (or a trained implanter at a rescue centre). Take your cat in a secure carrier. The chip is injected under the skin, usually between the shoulder blades, in a few seconds. It's often done alongside vaccinations or neutering.

Step 4: Check it's registered to you
Make sure the chip is registered on a government-approved database with your name, address and phone number. If the cat came from someone else, contact the database to transfer it into your name.

Step 5: Keep the details current
Update the database when you move or change your number. Some databases charge a fee for changes.
Tips
- If you use a microchip cat flap, the same chip can open it: handy for keeping neighbouring cats out.
- If you use a collar, choose a quick-release (snap-open) collar so your cat can't get caught.
When to call a professional
A vet should scan and implant chips, and is the only person who can certify an exemption if your cat has a health reason not to be chipped.
Questions people ask
My cat never goes out. Does it still need a chip?
Yes in England. Indoor cats can still escape, and the law applies to them too.
Can I chip a younger kitten?
Yes, kittens can be chipped before 20 weeks; 20 weeks is the latest deadline. Ask your vet when's best.
