Excellent company to deal with, nothing is too much trouble and Geoff the owner checks every detail to make sure what you order online is exactly what you need. I first used them 5 years ago for a work project and have just used them again for my house. I'd highly recommend them!

Tim Rawling

I had an old rotten window on the back wall of my garage. Local window companies either didnâ€™t want to install a single window or wanted to charge £800. I measured up and ordered a window from DIYUPVC with a fitting pack. I collected the window from them, and they gave me some advice on the install, which turned out to be straightforward. Highly recommended.
