I had an awful experience with the "engineer" who was sent. I had clearly said I wanted 5 radiators removed temporarily for decorators. When Samir Rezzak arrived (late - after I had called twice) he thought he was removing one and spoke about cutting the pipe on my brand new radiator! At that point I asked him if he knew what he was doing. He said yes but I should have stopped him there. There followed the hour from hell. I had to manage the water from the draining system in my garage so it wasn't flooded and he was using bowls and buckets to drain the radiators. He had no equipment with him and eventually said I would need a heating engineer to set up my system again as he couldn't do it! He tried to refill the system and water leaked from all 5 radiator sites onto carpets and flooring. I don't believe he was qualified or experienced. I called customer services the following day but they have not returned my call. I will never use this site again.
