Microchipping Law: Complete Guide
Everything you need to know about UK microchipping requirements, regulations, and how to ensure compliance.
The Microchipping Law
The Microchipping of Dogs (England) Regulations 2015 (and similar in Scotland and Wales) require:
- All dogs must be microchipped by 8 weeks of age
- Contact details must be kept up-to-date
- Dogs must be registered on an approved database
- Failure to comply can result in fines up to £500
- Local authorities can serve a notice requiring microchipping within 21 days
Important: This law applies regardless of whether your dog leaves your property. It's a blanket requirement for all dogs.
Who Is Responsible?
Breeders: Must microchip puppies before they go to new homes (by 8 weeks)
Owners: Must ensure their dog is microchipped and details are current
New owners: Must update database with their details when acquiring a dog
How Microchipping Works
Microchipping involves:
- Implantation: Tiny chip (size of grain of rice) inserted under skin, usually between shoulder blades
- Identification number: Each chip has unique 15-digit number
- Registration: Number registered on approved database with your contact details
- Scanning: Vets, rescue centers, and authorities can scan chip to read number
- Database lookup: Number is used to find your contact information
The microchip itself doesn't contain your information - it only stores the identification number which is linked to database records.
Approved Databases
Your dog must be registered on an approved database. Main databases in UK include:
- Petlog (Kennel Club)
- Identibase
- Pet Identity UK
- SmartTrace
- Microchip Central
Important: Check which database your dog is registered with - you'll need this information to update details. Your vet or the person who microchipped your dog should provide this information.
Cost of Microchipping
Typical costs in the UK:
- Standard microchipping: £15-£30
- Free/low-cost options: Some charities and local authorities offer events
- Database registration: Usually included in microchipping fee
- Database updates: Often free, sometimes small fee (£5-£15)
Some veterinary practices include microchipping in puppy packages. Check with your vet about options.
Keeping Details Up-to-Date
Legal requirement: You must keep your contact details current on the database.
Update immediately if you:

How to update:
- Contact the database your dog is registered with
