After the hot water failed in our old house, we got six different quotes to replace our ancient boiler: BG and others. One further plumber said the job was too big for him; another quoted but did not look confident. Ian Herbert discussed the system with us, estimated the boiler size and recommended pressurising. We went with R&H because of theexplanations Ian gave us; the quote was very reasonable and we were able to talk to others who had work done by R&H. Jason did the work very efficiently but on the last day the hot water just wouldn't work. Richard came and diagnosed a blockage in the pipework. The exact location would be determined by cutting the pipes. We have probably miles of pipework. However, when Jason came back he identified the exact location of the blockage much faster than we feared, and with little disruption; he just replaced a small section of pipe. The system is now working brilliantly. Very happy customers!
