Yes, most B&Q stores are open on Bank Holiday Monday, but they do like to mess with your head a little. They usually run on their Sunday trading hours, which is a fancy way of saying “we’ll open later and close earlier than usual.”
Think of it as a gentle compromise between your desire to paint a fence and the universe’s desire for you to eat a sausage roll. You’ll typically find them open from 9:00 AM to 6:00 PM or 10:00 AM to 4:00 PM, but don’t you dare assume—check the store locator first. It’s like a treasure map, but with fewer pirates and more lightbulbs.
