I purchased 2 three panel bifold doors in Aug 2018 and they were installed in Oct 2018. I have had no end of problems with installation and after sales service since I bought these doors. You have to pay the whole purchase price (only by BACS) before they would install it and when you have a problem you spend your time on the phone trying to get to speak to someone. After installation, if you have a problem with the doors (even though it's under warranty) you have to pay £199 plus vat (they say it's a call out charge) before they will come to fix it. They will try everything to make sure that the problem is not under warranty so that they don't need to refund the call out charge. I rang them to say that the track under one of the 3 panel doors was broken. They said that as it's the track tape it won't be under guarantee as it's wear & tear and wanted me to purchase a track tape for £45 plus vat & fit it myself. I said it's under 3yrs old and according to consumer law a product has to be fit for purpose, so it's covered by warranty and paid the fee. The fitters came to fix it and told me that "Bottom Hinge block had no locking screws in it so the block had slipped back causing door to not open and damage bottom track tape". Luckily I took a photo of the report. They refused to refund my money "technical" has "advised that the problem with the track tape was down to general wear and tear and would not be covered under warranty". I have reported them to trading standards and will be taking them to the small claims court to get my money back. If everyone who has had a bad experience with them ring national citizens advice line, they will report them to trading standards (they will be forced to investigate) and help you to get compensation and/or your money back.
