Boiler Repairs & Servicing in Colchester
No hot water, no heating, or a boiler locking out with an error code? We diagnose and repair boilers across Colchester, usually the same day you call.
Fast diagnosis, honest advice
We test the fault properly rather than guessing at parts. If the repair is sensible we fix it; if the boiler is beyond economic repair we tell you plainly and price a replacement, without pressure.
Annual servicing that protects your warranty
A yearly service keeps your manufacturer warranty valid, catches wear before it becomes a breakdown and keeps the boiler running efficiently. We check combustion, seals, pressure, controls and safety devices, and leave a written report.
Common faults we fix
Low pressure and repeated refilling, frozen condensate pipes in winter, faulty diverter valves causing hot water but no heating, failed pumps, blocked heat exchangers, thermostat and PCB faults, and persistent lockout codes.
