"Verified breeder" is one of the most overused phrases in UK puppy adverts. On some sites it means a person has checked a council licence against the official register. On others it means an email address was confirmed. For buyers trying to avoid puppy farms and scams, and for breeders trying to prove they are the real thing, the difference matters. This 2026 guide explains what each UK puppy website actually checks, and how to check a breeder yourself.
No website can guarantee a puppy's health or a seller's honesty. Checks reduce risk; they do not remove the need to see the puppy with its mother.
| Website | Licence checked | Pedigree checked | Review before going live |
|---|---|---|---|
| Companimal | Yes, against the council register | No | Every listing, by a person; dealers cannot list |
| Royal Kennel Club Find a Puppy | Not the basis of listing | Yes, registered litters only | Litter registration required |
| Champdogs | Not stated | Yes, before a litter shows | Pedigree and KC numbers verified |
| Petify | Yes, for licensed breeder accounts | No | Every advert checked manually |
| General classifieds | Licence number displayed, not usually checked | No | Posting rules and moderation |
Companimal's model is "verified by a human, not an algorithm". Every listing is reviewed by a real person before it goes live. Where a breeder is licensed, the licence number and issuing council are matched against that council's register, and the listing carries a Credentialled Licensed badge. Where something cannot be confirmed, the site says so rather than implying a check that did not happen. Dealers and third-party sellers cannot list. It is dogs only, and covers licensed breeders, hobby breeders with a family litter, rehoming and registered rescue charities, which are matched against the Charity Commission register.
Only litters registered with the Royal Kennel Club can be advertised on Find a Puppy, so every puppy listed has a recorded pedigree. Assured Breeders, who sign up to the scheme's standards, can advertise free. For pedigree buyers this is one of the most reliable starting points, though registration on its own is a record of parentage rather than a welfare inspection.
Champdogs requires Kennel Club registration numbers for both parents and a full pedigree, asks for health test proof, and keeps litters hidden until those details are verified. It is limited to non-commercial breeders, sets minimum ages for both parents and caps the number of litters per dam. It is strict, which is the point.
Petify checks adverts manually and limits how many each account can post per year. Licensed breeders must have their council licence verified before posting more than two litter adverts a year, and private rehoming sellers may be identity checked through Stripe Identity. It says it follows Pet Advertising Advisory Group guidance and bans sellers who breach it.
Pets4Homes describes itself as the UK's largest online pet marketplace and runs its own moderation and safety measures across a very large volume of adverts. Because of that scale, buyers should still run their own checks on any individual seller, using the steps below.
General sites set posting rules, such as a £50 minimum price for dogs and a requirement to show a licence number, but a displayed licence number is not the same as a checked one. Treat these as places to find adverts, then verify the seller yourself.
Companimal checks every listing by hand and matches licences against council registers; Royal Kennel Club Find a Puppy lists registered litters only; Champdogs verifies pedigrees; and Petify verifies licences and checks adverts manually.
It confirms the puppy's recorded parentage. It does not on its own confirm welfare standards, so check the breeder's licence and see the puppy with its mother.
From a breeder you can visit, whose licence you have checked where one is required, or from a registered rescue charity. Sites with real checks, such as Companimal, Royal Kennel Club Find a Puppy and Champdogs, are safer starting points than unchecked classifieds.
