Great product although had an absolute nightmare as they only sell through (supposedly high-end) window/door companies that fit them. The company that did ours were a bunch of cowboys (Basfords in Nottingham) - basically give you all the spin.... great quality....all about YOUR leadtime, not ours.....look after you all the way through and beyond... None of this was true and because (stupidly) we paid all the money up front they were not at all quick at resolving the (many) problems. We had the B team fitters who made an absolute mess then the better fitters although not a lot to choose between them as we still continued to have problems (and are still not resolved after 7 months since we paid). The doors had to be refitted, the wrong gaskets were fitted, then fitted shodily and had to be redone, the doors weren't screwed in at the bottom and therefore couldn't have them open, scratches, poorly cut sills, wrong sized glass, wrong colour sealant, not to mention the huge leadtimes and many times of promising to come to resolve issues then not turning up. Finally with the latest issue of the door sills moving 7 months down the line, we put a complaint into Origin to get help on ensuring that Basfords were finally fitting correctly as they are responsible for ensuring that their sole distributors are fit for purpose - we were told that one of their surveyors would come out at the same time as Basfords to check the work then a few days later they said our contract was with Basfords and they could do nothing to help us!!!!! At this point I can only conclude that Origin are as bad as Basfords and do not care about the customer service surrounding their products. So as I say, great product however what good is that if you cannot guarantee the fitting / quality / leadtime or Customer service....... Very poor indeed.
