Central heating system broken down? Cold radiators throughout your home? Our Gas Safe emergency heating engineers diagnose and repair central heating system faults fast.
Emergency Central Heating Repair Services
Expert diagnosis and repair of all central heating system faults.
Complete System Failure
Entire central heating system not working. All radiators cold. We diagnose the boiler, pump, controls and system to identify why nothing is working and repair it.
Central Heating Pump Failure
Boiler fires up but radiators stay cold. Often caused by a failed central heating pump not circulating hot water. We replace faulty pumps with quality replacements.
Motorised Valve Fault
Heating or hot water not responding to controls. A stuck or faulty motorised valve can prevent the heating circuit from opening. We diagnose and replace faulty valves.
System Blockage or Sludge
Radiators have cold spots or cold at the bottom. Sludge, rust and debris in the system restrict flow and reduce efficiency. We can powerflush the system if needed.
Expansion Vessel Problems
System pressure rising too high or dropping rapidly. A failed expansion vessel or pressure relief valve can cause pressure issues and boiler shutdown.
Pipework and Radiator Repairs
Leaking radiators, leaking pipework, seized radiator valves or corroded fittings. We repair or replace central heating pipework and radiator components.

Central Heating Repair FAQs
Common questions about emergency central heating repairs
What are the most common central heating faults?
The most common faults are failed central heating pumps, stuck motorised valves, low system pressure, air in radiators, faulty thermostats or programmers, blocked condensate pipes and sludge or debris in the system.
How do I know if my central heating pump has failed?
The boiler may fire up but radiators stay cold. You may hear the boiler making a banging noise or the overheat thermostat tripping. The pump itself may be silent instead of humming or feel very hot to touch.
What is a motorised valve and what does it do?
Motorised valves control whether hot water from the boiler goes to your radiators, hot water cylinder or both. A faulty valve can prevent the heating from coming on even though the boiler is working correctly.
Why do my radiators need bleeding regularly?
Repeated air in radiators can indicate a system leak letting air in or corrosion in the system producing hydrogen gas. It is worth investigating the root cause rather than just bleeding radiators repeatedly.
What is a powerflush and when is it needed?
A powerflush uses a high flow rate pump and chemicals to clean sludge, rust and debris from your central heating system. It is recommended when multiple radiators have cold spots, the system is noisy or the boiler keeps breaking down.
How much does a central heating pump replacement cost?
The cost depends on the pump type and accessibility. Our engineer will provide a quotation before carrying out the work. We carry common pump models and can replace a failed pump on the same visit in most cases.
