Independent profile snapshot

This extended snapshot summarises how the provider presents itself in the UK market. It supplements the dataset-led summary above.

Which? is the UK's leading independent consumer champion, providing expert broadband reviews, testing, the Which? Switch Broadband service and Which? Recommended Provider accreditations alongside consumer advocacy across wider household products, services, insurance and consumer rights, trading since 1957 as the operating name of the Consumers' Association (a registered UK charity, number 296072). Registered as Which? Limited (Companies House 00677665, incorporated 13 December 1960) at 2 Marylebone Road, London NW1 4DF and led by a board including Kenneth Danquah, James Edward Fairclough, Kevin Harry Gaskell, Anabel Hoult, Christina Jane Scott, Emma Jane Scott and Nigel Gregory Vaz, the company operates as an independent charitable consumer champion rather than a commercial comparison platform. Which?'s Recommended Provider badge is widely regarded across the UK telecoms industry as the single most authoritative independent consumer quality accreditation for UK ISPs, with only a small number of altnets and mainstream providers receiving the annual accolade. Which? has been awarded Consumer Champion of the Year and retains unique independent consumer advocacy authority. Trustpilot 4.4 from 15,000+ reviews. Contact 029 2267 0000 or via which.co.uk form.
