I'm a professional kitchen and bathroom fitter - Screwfix are my #1 parts and hardware supplier, and I spend £thousands with them every year. This happens for reasons. They're ultra-reliable, they carry large stocks, they get 95% of non-stock items by midday the next day, my local branch staff are super-helpful - etc. etc. etc. I notice that virtually every negative review is posted by a snowflake member of the public who seems to think that a trade supplier should roll out a red carpet every time they walk in for their annual visit, and that a £4 wallpaper pasting table should be made of cast-iron studded with diamonds and pearls. I'm in there practically every other day, I've been dealing with them for years, and there's never been a single, solitary bad experience. Judge for yourself based on the above numbers.
