B&Q being a decade older than Home Depot, its more like HD "borrowed". However, there was a temporary merger between Home Depot and B&Q between 1999 and 2005, which only didn't get finalized because B&Q was too big for HD to buy (B&Q being only a small part of the Kingfisher Group). During this period, and up to around 2015, DIY.com took you to either Home Depot or B&Q based on your geographical location.
