If you, like my wife and I have a microsystem of central heating, I would guess that you are having, or will at some stage, have a few problems and once they start they don’t go away. Our system was installed when the house was built in 2000 and when we had to replace the boiler recently, those problems quickly rose to the surface. Nevertheless, the guys at Mark Bishops got to the bottom of it and it is now running better than it ever has. Big thanks to all, and there were a fair number coming and going, but particular thanks to Chris and Matt. I have no hesitation in recommending Bishops, just one word of warning, make sure you have plenty of tea and sugar.
