Avoid this compnay like the plague! Awful customer service, installers were rude, one of them peed on the outside of my house even though we had a working toilet (they were even installing the window in the toilet room??!), laughed at me and turned up late every single day (took more days than needed as they were only working half days due to turning up so late). When installed there were cracks and chips in the windows, there were draughts coming through the windows and doors, the windows didn’t shut correctly so we had the heating on full throughout winter for months until it was finally fixed! All they offered was £300 off the £10,000 bill. DO NOT USE THIS COMPANY! I wish I researched more into the reviews seeing so many bad ones after using them! Caused so much unneeded stress and anxiety. Disgusting.
