Fit the best they quote more like fit the worse, we had windows and a door fitted by Everest. Product looked fine at installation then 4 weeks later our front door broke, Wouldn't shut, kept catching and even sometimes it opened on its own. Called the service centre very poor service eventually after 3 weeks of waiting constant calls we had a couple of fitters turn up.

They decided the best way to fix the issue was to put a screw through the lock, 2 weeks later same problem but worse. On one occasion couldnt even get into my home. As well as the door one windy evening our blinds in our bedroom were moving as i investigated there were massive gaps in the frames of the windows where they shut two good thing it wasn't winter. All my handles had broke and they hadn't set the windows properly so they scrapped and made strange nosies. They have fixed the window now but still haven't recieved my handles and my door still hasn't been fixed. My advice use another company to do your windows do not use everest unless you want poorly fitted windows.
