The National Hamster Council receives many enquiries from individuals who are looking to find hamster breeders in their area and you can find information on breeders through your regional hamster club, either Northern, Midland or Southern Hamster Club. All clubs have information about exhibitor/breeders in their Club on their websites:

Northern Hamster Club: https://northernhamsterclub.co.uk/index.php…
Midland Hamster Club: http://www.midlandhamsterclub.co.uk/breeders.html
Southern Hamster Club: http://www.southernhamsterclub.co.uk/about-th…/shc-breeders/

You can also contact the Club Secretary (contact information is on the club websites). When you contact the Secretary, do mention which species of hamster you are interested in and where you are based.
