First service of a relatively new boiler in a house I moved into earlier in the year, but had no instructions how to set the boiler to work to its optimum, also I had a towel rail not working and an upstairs radiator not working as it should do. Young lad arrived and listened to me waffle on about the above, then as he removed the panel under the boiler cupboard there were the instructions :-) Boiler was serviced, the bar corrected it was way to high, thermostat checked and both upstairs radiators fixed all within an hour. What a difference having things working properly has made to the temperature of the house now, totally brilliant, and extremely good value. Simon Barker was recommended to me and I have no problem recommending to anyone else.
