I moved into a house which had Origin Bi Fold doors installed in 2014 by A1 Windows and Conservatories (originally based in St Neots now in Bedford). The doors have a gap between the top right hand corner of the lead door and the frame. Despite several attempts to contact A1 Windows and even reporting them to FENSA (apparently they were not registered by FENSA at the point of my installation) they have not replied to me. Origin have tried to help, but have said that this is an issue with the installation of the doors and not a warranty issue. They have offered to come and inspect the doors for a fee (£150 ish + VAT). I have the details of another installer in my area, but am extremely weary of any recommended Origin installer after the attitude of A1. This is not the level of customer after care I would expect from any professional company.
