Our independent heating engineers can diagnose and resolve problems with your heating, including boiler, radiators, hot water system and controls. We have expert, Gas Safe Registered plumbers who will work out what is wrong and fix it for you.
Faults with modern boilers, like with computers, sometimes fix themselves if you turn the boiler off and on again!
If a restart doesn’t work, there may be an error code showing on the boiler. If the boiler just has a two-digit display, watch it carefully, as the code might be displayed in a sequence of numbers (e.g. changing between “TR” then “05” would be error code “TR05”). If you still have the manual, see what that error code means. If you don’t have the manual, trying Googling the manufacturer of the boiler and the error code (E.g. “Vaillant F.28“). Even if you can’t do anything to fix it, telling us the error code when you book online makes things easier for your plumber.
A common boiler fault is where the pressure of water in the radiators falls too low. There will usually be a small dial on the front of the boiler. If the needle on the dial is below the green section, your pressure is too low. You can fix this yourself by using the filler loop below the boiler to add more water to the system. But be careful: don’t put too much in, and be aware that there is almost certainly a small leak somewhere in your system which is allowing some water to escape or evaporate leading a loss of pressure. You should get a plumber to locate and fix that leak.
