Oh, I do hope not. I'm in England, and DIY everything; I've plumbed up a kitchen before, and built a staircase, all using parts from B&Q (the store mentioned in the Guardian article).
It should be noted that B&Q's owners also own the Screwfix chain, and are opening Screwfix (trade) outlets to replace the B&Q's they're closing, presumably to cut down on the customer service requirements. If you know what you're doing, such trade outlets are open to you; if you don't, there's always YouTube to learn things.
