Matt arrived on time and got straight down to work fitting my new boiler. It was a freezing cold, icy day but it didn't deter him, not even going up on the icy roof to fit the vent. He put coverings down on the floor and surfaces to protect them. I went out for the day and left hime to it with the request that he phoned me half an hour before he was due to finish. He did exactly that. I arrived home to find my new boiler installed and everywhere clean and tidy. It took hime 7 hours to install the boiler but was kind enough to stay and set the boilers programme for me on the control device for me and answer my numerous questions regarding the thermostat, how to add water if necessary, etc. This was a great benefit to me and put my mind at rest that I would be able to cope of there was a problem. He left saying I could calll on him at any time if I wasn't sure of anything or thought there was a problem.
