We called HH and received a competitive quote for a power flush. We had no hot water and no heat from the radiators. Our boiler is old and had many complaints. Matt worked tirelessly trying to overcome each obstacle in order to get our system functioning. He was very informative and clear about each problem and his solution. He left with the system working with hot water and hot radiators. We also had more water pressure in the hot tap after the power flush. We also received some very good advice on what we needed to do in future to keep our combi boiler going. I highly recommend HH and am very pleased with the professional positive attitude and the dogged determination to fix our boiler. Thank you. Kalash
