An address change that is easy to forget
A pet’s microchip is only useful if the database record leads back to the keeper. Moving house makes the address on that record wrong overnight. This article summarises the GOV.UK guidance “Get your dog or cat microchipped” and the text of the Microchipping of Cats and Dogs (England) Regulations 2023. The Regulations extend to England and Wales but apply in relation to England only. GOV.UK says the rules for cats differ between England and Scotland, Wales and Northern Ireland, while the rule for dogs applies across the UK. It is general information, not legal advice.
Who must microchip
GOV.UK says all dogs in the UK must be microchipped and registered by the time they are eight weeks old. For cats, it says that in England a cat must be microchipped and registered by the time it is 20 weeks old, including cats that usually stay indoors, whereas people in Scotland, Wales and Northern Ireland can choose to microchip their cat. The England Regulations set the same ages: a keeper of a cat older than 20 weeks, or a dog older than eight weeks (other than a certified working dog), must ensure it is microchipped. The requirements for cats came into force on 10 June 2024.
What counts as microchipped
Under regulation 3(4) of the England Regulations, a cat or dog is microchipped where a compliant microchip has been implanted and the details required by regulation 6 are recorded on a database. Those details include the full name and address of the keeper and the keeper’s contact telephone number, if any. In other words, the legal test for “microchipped” is not just the chip, but the database record as well.
Updating details after a move
GOV.UK says the keeper is responsible for keeping the pet’s microchip information up to date, for example if the keeper moves house. The way to do it is to contact the database company the pet is registered with, and GOV.UK notes that a fee may be charged for updating the information. The Regulations set out a specific duty for a change of keeper: a new keeper must, unless the previous keeper has already done so, record their full name, address and contact number, and any change in the animal’s name, with the database. The Regulations do not set a time limit for that duty.
Finding out where a pet is registered
GOV.UK says a keeper who does not know which database holds the record can check using the microchip number. Someone without the number can ask a vet, a dog warden or a rescue centre to scan the pet. The guidance lists many approved databases that meet government standards. It also states that one database, Track Your Paws, does not meet government standards and has been removed from the list, and that pets registered there should be re-registered with a different database.
Fines and enforcement
GOV.UK says a keeper can be fined up to £500 if a dog or cat is not microchipped when it needs to be, or not registered on an approved database. The Regulations work through notices. Where a cat or dog has not been microchipped, an authorised person may serve a notice requiring the keeper to have it microchipped within 21 days, and failure to comply with that notice is an offence punishable on summary conviction by a fine not exceeding level 2 on the standard scale. Transferring an animal to a new keeper before it has been microchipped is a separate offence with the same maximum.
Scam emails
GOV.UK warns that an email from any database other than the keeper’s own, asking for money to register the pet, could be a scam. Suspicious emails can be reported to the National Cyber Security Centre. A move is a time when a keeper is more likely to be expecting messages about addresses, so the safer approach is to go to the database company directly rather than follow links in an unexpected email.
Collars, tags and buying a pet
A dog must still wear a collar and tag with the keeper’s name and address when in a public place, according to GOV.UK, so the tag needs a new address as well. The same guidance says that anyone getting a dog or cat should ask for proof that a microchip has been fitted, such as a microchip certificate, vet records or a pet passport, and must make sure the microchip details are updated to their own.
The bottom line
After a move, the microchip record should be updated to the new address through the pet’s database company, the dog’s tag should be changed, and any email asking for money to update the record should be treated with suspicion. Dogs must be microchipped across the UK, and cats must be in England, where a microchip is treated as valid only if the keeper’s details are recorded on an approved database.
