Which?

Which? is a brand name used by the Consumers' Association, a registered charity (No. 296072), and company limited by guarantee (No. 580128), which is based in the United Kingdom. It exists to promote informed consumer choice in the purchase of goods and services, by testing products, highlighting inferior products or services, raising awareness of consumer rights and offering independent advice. The association owns several businesses, including Which? Financial Services Limited (Which? Mortgage Advisers), Which? Legal Limited, and Which? Limited, which publishes the Which? magazine.

The vast majority of the association's income comes from the profit it makes on its trading businesses, for instance subscriptions to Which? magazine, which are donated to the campaigning part of the organisation to fund advocacy activity and inform the public about consumer issues. Which? magazine maintains its independence by not accepting advertising and the organisation receives no government funding. The Consumers' Association is the largest consumer organisation in the UK, with over 1 million subscribers to its magazine.
