When to call us
No heat or hot water
The classic boiler failure. Could be ignition, sensor, pump, or PCB — we'll diagnose and quote on the spot.
Pressure keeps dropping
Indicates a leak in the heating circuit or a failed expansion vessel. Both fixable.
Banging, kettling, or whistling
Usually limescale buildup or sludge in the system. A power flush or descale solves it.
Boiler keeps locking out
Persistent fault codes or repeated lockouts mean a sensor or component needs replacing.
Boiler over 12 years old
Modern condensing boilers are 30%+ more efficient. May be cheaper to replace than keep repairing.
Annual service due
Manufacturer warranty requires it — and a serviced boiler lasts longer and runs more efficiently.
