Ben installed a new combi boiler for us. He arrived on time and prepared the area against any chance of mess. I was impressed by the speed and efficiency he worked at, having to take out all the old equipment. The boiler is excellent and Ben took us through how the controls work until we understood everything. Ben fitted a towel rail and also taps in the kitchen and ensuite. I can not recommend GS Heating highly enough, Ben is professional, friendly and courteous.
