Speaking as someone who can and does DIY it, the stores that have been mentioned and Homebase in particular fell by the wayside years ago in terms of product, price, and service in store. They veered off course by deciding to concentrate in the big buy kitchen and bathroom set ups which were in the main over priced and usually poor imitations of good brands hiding behind a "named and recognisable" trade name. I do all my shopping for such as I need at Screwfix, online, and delivered the same day if ordered before 10am. For motor requirements I use Euro Car Parts, again with the same set up as Screwfix. I have an account with both companies and am happy with the service and the technical advise that is offered by knowledgeable staff. B&Q saw the writing on the wall and duly snapped up Screwfix but have mercifully not changed the format or relocated the company to the soulless sheds that they themselves occupy. Plus the garden centres that they have in store are not worth touching as the plants are usually not a patch on the local garden centres. Perhaps for fence posts and the occasional hozelock upgrade, otherwise not worth the trip.
