Boiler repair in Leicester
Pressure drops and worn diverter valves cause many Leicester breakdowns. The usual repair costs are set out here, before any engineer visits.
Boiler problems common in Leicester homes
Across Leicester, the same handful of faults cause most breakdowns: pressure dropping, a pump or diverter valve giving out, a failed fan or a flame sensor that has worn. Older combis in terraced homes and tank-fed boilers in semis account for many of them. Where a boiler is over 12 years old, a replacement quote beside the repair price lets you weigh it up.
Red-brick Victorian terraces: Plenty of these homes still have boilers from the early 2000s. Fan, sensor and diverter faults are the usual reasons they stop.
Interwar and postwar semis: Older regular boilers with a feed tank in the loft are still around, so expect leaking cylinders, failing pumps and sticking valves.
Estates built from the 1990s onwards: Pressure loss and condensate blockages are typical, along with worn components on first-generation builder-fit combis.

Boiler repair in Leicester: questions
How much is a boiler repair in Leicester?
Most diagnostic visits are £80 to £120. Common parts like a pump, fan or diverter valve usually cost £150 to £350 fitted. A printed circuit board, the boiler's main control unit, is typically £250 to £450.
Why is my combi giving hot water but no heating?
A stuck diverter valve is the most likely cause, since it decides whether hot water goes to the taps or the radiators. Check the thermostat and timer first. If they are set correctly, book an engineer.
My old tank-fed boiler keeps breaking down. Is it worth fixing?
If it is over 12 years old and has needed several repairs, a combi or system boiler upgrade is often cheaper over a few years. If it is newer and only one part has failed, a repair is normally fine.
I can smell gas. What first?
Get out of the building, leave switches alone, and phone the National Gas Emergency Service on 0800 111 999. Only arrange a repair once the emergency engineer has made it safe.
