Common problems we fix

Common jobs we handle most often. Tap a problem for the useful detail.

Boiler breakdowns
Typical cause
Ignition faults, pressure loss, error codes or failed components shutting the boiler down.
What we do on arrival
Read fault codes, check pressure and flues, then repair or advise on replacement if uneconomical.
Time to fix
Many faults clear same visit; some parts need ordering.
No hot water
Typical cause
Diverter valves, thermostats, immersion heaters or cylinder issues.
What we do on arrival
Establish whether heating and hot water both failed, then target the failed component.
Time to fix
Depends on system type (combi vs conventional).
Radiators cold or uneven
Typical cause
Sludge, balancing issues, failed TRVs or airlocks.
What we do on arrival
Bleed, balance, power-flush where needed, or replace failed valves.
Time to fix
Simple balancing is quick; full flush is a planned visit.
Boiler servicing
Typical cause
Annual service keeps efficiency up and helps protect warranties.
What we do on arrival
Strip-down check, clean key parts, test safely and record findings.
Time to fix
Typically a scheduled daytime appointment.
Immersion heaters
Typical cause
Failed elements or thermostats leaving the cylinder cold.
What we do on arrival
Isolate electrics, test and replace the failed part.
Time to fix
Often same-day when access to the cylinder is clear.
Thermostats & controls
Typical cause
Failed room stats, programmers or smart controls stopping heat on demand.
What we do on arrival
Test the control chain and replace or reconfigure as needed.
Time to fix
Usually a short visit once wiring access is available.
Boiler pressure problems
Typical cause
Leaks on the system, failed expansion vessels or habitual repressurising.
What we do on arrival
Find why pressure drops, fix the leak or vessel, then set pressure correctly.
Time to fix
Diagnosis first; repair length depends on leak location.
Commercial heating
Typical cause
Plant rooms and larger systems need experienced engineers and the right parts.
What we do on arrival
Assess safely, isolate plant as required, then repair or quote larger works.
Time to fix
Scoped per site — we confirm before major works.
