Hi, i've just had a new heating system installed and it cost me £2500 but when i checked the price of my new combi boiler it was around £850 and am i right in think that a heating & plumbing company would get this even cheaper at trade prices? It took 2 of them a day to install it and they had to reroute the pipes so i could have the new boiler in a slightly different place but i know one of them was only a trainee who was at college. Also i checked the price of the room thermostat controller and found that it was only £35 and it didn't even have a holiday setting. So even with extra copper piping and a few other bits, the total cost of everything was around £1000, so i have been charged £1500 in labour costs, surely this is high or am i wrong. The cheap thermostat controller really upset me as this is controlling everything and i'm not even sure the digital temperature on it is accurate. I would appreciate any input, thanks...Mick
