New gas hob and sink fitted and help with boiler issue

Josh was personable yet professional. He initially came to fit a new gas hob and install a new sink, I was really pleased with the work as it required cutting into the worktop. He listened to what I wanted and the job was perfect. When I had an issue with my boiler a few weeks later I text Josh with a brief diagnostic and he called and talked me through how to rule out certain issues. The instructions were spot on and enabled me to identify a problem with the pump which had got stuck...once released the heating and hot water ran again. Cannot recommend Josh and his workmanship enough
