FAQs About Boiler Repair London
- Low Boiler Pressure: Often indicated by a low reading on the pressure gauge. While sometimes easily fixed by repressurising the system, persistent low pressure can signal a leak that requires professional attention.
- No Heating or Hot Water: This can stem from various causes, such as a faulty thermostat, issues with the pilot light or ignition system, a malfunctioning pump, or a blockage within the system.
- Boiler Leaks: Water leaks from the boiler unit or associated pipework are a serious concern and should be addressed promptly by a Gas Safe registered engineer to prevent further damage and potential safety hazards.
- Unusual Noises: Gurgling, banging, whistling or hissing sounds emanating from your boiler can indicate trapped air, low water pressure, a failing pump, or scale build-up. These noises often point to underlying issues needing repair.
- Cold Radiators: If some or all of your radiators are cold while the boiler is running, it could be due to trapped air in the system, a build-up of sludge or corrosion or a problem with the circulation pump.
- Frozen Condensate Pipe: Particularly common during cold weather in Central London, a frozen condensate pipe can cause the boiler to shut down. Thawing the pipe may resolve the issue, but if it’s a recurring problem, preventative measures may be needed.
- Boiler Keeps Switching Off (Kettling): This can be caused by limescale build-up within the heat exchanger, leading to overheating and the boiler cutting out.
- Faulty Diverter Valve: Often found in combi boilers, a faulty diverter valve can cause issues with hot water distribution or prevent heating from working correctly.
- Check the Thermostat: Ensure your thermostat is set to the correct temperature and has power (check batteries if applicable).
- Verify Gas and Electricity Supply: Make sure your gas supply is on and that the boiler is receiving power (check the mains switch and any fuses).
- Check Boiler Pressure: Look at the pressure gauge on your boiler. If it’s significantly below the recommended level (usually around 1-1.5 bar, but consult your manual), you may need to repressurise it (refer to your boiler manual for instructions).
- Look for Error Codes: Many modern boilers display error codes. Consult your boiler manual to understand the meaning of any displayed code, as this can provide valuable information for our engineers.
- Attempt a Boiler Reset: If your manual provides instructions for resetting the boiler, you can try this once. However, if the boiler repeatedly faults, do not keep resetting it, and call a Gas Safe engineer.
- The Nature of the Fault: Simple fixes, such as repressurising a boiler or thawing a condensate pipe, will generally be less expensive than more complex repairs involving faulty components.
- The Specific Parts Required: If replacement parts are needed, the cost will depend on the type and availability of these parts.
- The Time Taken for the Repair: Our labour charges are based on the time required to diagnose and fix the issue.
- The Type of Boiler: Some boilers may have more complex components, potentially increasing repair costs.
- Safety: Gas appliances can be dangerous if not installed or repaired correctly. Gas Safe registration ensures that engineers are qualified to work safely with gas.
- Legality: It is a legal requirement in the UK for anyone working on gas appliances to be Gas Safe registered.
- Expertise: Gas Safe registered engineers have the necessary training and knowledge to diagnose and repair boiler faults effectively and safely.
- Warranty Protection: Using a non-qualified person for boiler repairs can invalidate your boiler’s warranty.
- Peace of Mind: Knowing that a Gas Safe registered engineer has carried out the repair provides peace of mind that the work has been done to the required safety standards.
- Combi Boilers (Combination Boilers): These are the most common type, providing both heating and hot water on demand.
- System Boilers: These work with a separate hot water cylinder and are suitable for homes with higher hot water demands.
- Conventional Boilers (Heat-Only Boilers): These also work with a hot water cylinder and often a cold water storage tank.
- Electric Boilers: While less common for central heating in larger properties, we can also repair electric boilers.
