What Interpet does

Interpet is a UK-based manufacturer of branded aquarium and fishkeeping care products, founded in the early 1950s by British chemist Dr Neville Carrington and originally known for its innovation in liquid fish food (Liquifry). The company is now part of the sera Group, a multi-brand European platform that also encompasses sera, Blagdon and Aquagarden. Interpet operates as a private limited company (Aquagarden Interpet Ltd.) registered in England with headquarters at Hamwood, Bishop's Hull Hill, Taunton, and employs between 101 and 250 people.

Its product portfolio spans the full aquarium care stack: Bio-CF internal cartridge filters (CF Mini through CF3), Deltatherm heaters with shatter-resistant glass and click-control thermostats, AirVolution ultra-quiet air pumps, Aqua Smart LED lighting with programmable control plus a Tri-Spec LED Android companion app, Clean Aquarium Pods water treatments, and a fish-medication range covering white spot, fungus, internal bacteria, and parasites. A Goldies World sub-brand addresses goldfish-specific demand, and educational support tooling such as the Fish Doctor diagnostic portal and a treatment dosage calculator extend the offering beyond hardware.

Interpet runs an exclusive B2B go-to-market: it does not sell directly to end consumers, instead supplying UK pet stores, specialist aquatics retailers, and online platforms including Amazon. A store-locator tool on interpet.co.uk routes consumer interest to nearby stockists. Marketing emphasises top-of-funnel content (website, Facebook, Instagram, email newsletter) and bottom-of-funnel retail referral, with the company restricting digital content use to UK residents in its Terms of Use. Revenue, pricing, and customer concentration are not publicly disclosed.
