B&Q

B&Q Limited (short for Block & Quayle after the company's two founders) is a British multinational DIY, home improvement and garden centre retailing company, with headquarters in Eastleigh, England. It is a wholly owned subsidiary of Kingfisher plc. It was founded in March 1969 by Richard Block and David Quayle.

It is the UK's largest home improvement retailer, serving both the general public and tradespeople. In contrast, its competitor Wickes primarily caters to trade professionals and does not sell soft homewares or operate garden centres. Where the British home improvement sector faced hostile competition in the 1990s, B&Q has become the dominant retailer in its sector following the demise of Focus in 2011 and Homebase in 2025.
