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.

Joshua FoxGoogle review★★★★★Essex Heating Engineers installed a new boiler for me in Rayleigh, and they were excellent from start to finish. The team was punctual, tidy, and really professional. The installation was quick, everything was explained clearly, and the new boiler works per...
Darren DeaconGoogle review★★★★★Ash arrived on time, gave us his advice and explained how we should proceed. His quote was reasonable and when we get his email we will arrange a time for the installation of a new thermostat. They covered our floors, so they didn't track anything in. They ...

Questions about boiler repair
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.
Should I repair or replace my boiler?
If the boiler is under ten years old and the part is available, repair is usually the right call. If it is older, parts are obsolete or it has needed several repairs in a row, a new boiler from £1,980 fitted may cost less over the next few years. We give you both options with prices and let you decide.
Do you repair older boilers?
Yes, as long as the parts can still be sourced. Many older Baxi, Potterton, Worcester and Vaillant models can be kept going for years with the right part. If a part is no longer made we tell you straight away rather than leave you waiting.
