Microchipping Laws in the UK: What Pet Owners Need to Know

Microchipping is the fastest way to reunite lost pets with their families—and in England it’s a legal requirement for both dogs and cats.

What the law says (England)

• Dogs: compulsory microchipping has been in place for years.

• Cats: as of 10 June 2024, owned cats must be microchipped before 20 weeks of age, and owner details must be kept up‑to‑date on an approved database. Non‑compliance can lead to a notice to microchip within 21 days and fines up to £500. Sources: GOV.UK – Cat microchipping now mandatory, GOV.UK – Microchipping for cats becomes compulsory.

How microchipping works

• A tiny chip, about a grain of rice, is placed under the skin (typically between the shoulder blades).

• It carries a unique number that links to your contact details on a secure database.

• Vets, rescue centres, and animal wardens can scan and contact you if your pet is found.

Keeping details up‑to‑date

• Moving house or changing phone number? Update the database immediately. This is a legal requirement and critical for reunions.

• Not sure which database your pet is on? We can help you find and update it.

Does it hurt?

• It’s quick—similar to a standard injection. Many pets barely notice it. We can microchip during other visits (e.g., vaccinations, neutering) for convenience.

Costs and benefits

• Typically around the cost of a routine consultation; it’s a one‑time procedure with lifetime identification.

• Increases the chance of a safe, fast reunion if your pet goes missing.

• Helps rescue teams distinguish owned pets from strays.

Lost your pet?

• Contact local vets, rescues, and wardens.

• Notify the microchip database so they can flag your pet as missing.
