What an awful company. We had 2 separate visits by 2 different 'engineers' - we advised them that all pipework had to be put out of sight under floorboards and they made us pay an extra £400. Months went by and they came out. As me and my husband were away my disabled son stood in for us. We rang the plumber they had sent and reminded him that no pipework was supposed to be showing - he said fine. They did the work for our central heating - putting all pipework 'on view' in the front room. They made my disabled son sign the paperwork. After countless phone calls and appointments where no-one turned up I rang and was told they would come and put everything right - pipework in front room and pipe trip hazard they had left upstairs. Plumber turned up, and we were told only trip hazard was to be done. Phoned Northern Gas but no-one there to do anything about other work. Do not go with this company whatever you do, or however desperate you are. From my experience their work is shoddy, they do not do what is agreed and they blatantly lie to you on the phone. I am taking legal action against them in the courts now as I have to get their work sorted out as it should have been in the first place.
