I am completely satisfied with the advice I received and with the work carried out by David Maxwell, a very pleasant and helpful Plumbingforce Engineer. The servicing of my boiler was far from straight forward, as I had in the past received very poor service from an engineer no longer working in this area. I received a detailed account of what had to be done. Having struggled for two years trying to cope with a very complicated thermostat, it is a great relief to now return to one I can understand. I have no hesitation in recommending Plumbingforce and in awarding them five stars. Anonymous
