We repair boilers in Chadwell St Mary most weeks, and the faults we see are shaped by the hard water in the Thurrock area (263 ppm), which scales up heat exchangers and jams diverter valves. With 81% of homes on mains gas, most of these are combi repairs. Our van is about 15 minutes away in Bowers Gifford.
A boiler that will not fire, keeps losing pressure, shows a fault code or leaves you with lukewarm water usually needs a repair rather than a replacement. We repair gas boilers of all ages and makes across Essex, including Baxi, Worcester Bosch, Vaillant, Ideal and Glow-worm.
The engineer diagnoses the fault first and tells you what it is, what it costs to fix and whether the boiler is worth repairing. Common parts such as fans, pumps, diverter valves, PCBs and pressure relief valves are carried on the van, and if a part has to be ordered we tell you when it will arrive and leave the boiler safe in the meantime.
We are Gas Safe registered (925538) and have been repairing boilers in Essex for more than 40 years, so we know the faults each model is prone to. Call-out starts from £90 and the repair price is agreed before we start.

Questions about boiler repair in Chadwell St Mary
How much does a boiler repair cost?
Call-out starts from £90, which covers the engineer's visit and diagnosis. Once we know the fault we give you a price for the repair including parts, and nothing is fitted until you have agreed it. If the boiler is old and the repair is not worth doing, we say so.
How quickly can an engineer come out?
Call 01268 855605 and we will tell you when the next engineer can be with you. If you have no heating or hot water we treat the job as a priority, and our emergency line runs 24 hours a day for breakdowns that cannot wait.
My boiler is showing a fault code. What does it mean?
Each manufacturer uses its own codes. On a Baxi, Worcester Bosch, Vaillant, Ideal or Glow-worm boiler the code usually points to a lockout from low pressure, ignition failure, a flue fault or an overheat. Tell us the code when you call and the engineer will arrive with the likely part on the van.
Why does my boiler keep losing pressure?
Pressure loss means water is leaving the sealed system somewhere. The usual causes are a weeping radiator valve, a failed expansion vessel, a passing pressure relief valve or a leak in the pipework. Topping up masks the problem, so we trace the cause and fix it.
