We had our garage converted to an extra room and it soon became apparent that there was a fault with the flooring. When we lifted the vinyl we found that the layer of cement over a concrete floor had all broken up. This had been laid because on completion the installer realised that the two floor levels didn't match up. A field engineer from Anglian visited us and agreed that it should not have happened. He reported it and several weeks later we received an abrupt letter (no address, no email address, no phone number) informing us that it wasn't covered under our 10 year guarantee. I disputed this and attempted to contact them numerous times and met with a wall of silence as they ignored my communications. Eventually by writing to the CEO I got a response from someone lower down the order who sent me a blank contract where it still failed to inform me why my particular problem could not be fixed stating that brickwork and plaster only had a year's guarantee - no mention of a cement layer over a concrete floor. For £16,000 I expected a better service rather than being fobbed off by a company who obviously have far greater muscle than I am able to offer. I strongly recommend anyone wishing to convert their garage should look elsewhere.
