A boiler service is a detailed inspection of your boiler and its operation. Regular servicing helps keep the appliance properly maintained, check that it is operating safely and identify signs of wear or developing faults.
Our Gas Safe registered engineers carry out the appropriate checks for your boiler and heating system, with any issues found explained clearly before further work is recommended.
A typical boiler service may include:
If we identify a fault or component that may require attention, we'll explain what we've found and advise on the appropriate next step.
Keystone London provides professional boiler servicing and repairs across West, South West and Central London, helping homeowners, landlords and managed properties keep their boilers properly maintained and resolve unexpected faults.
A standard Keystone London boiler service costs £120 + VAT. A combined boiler service and Gas Safety Certificate costs £195 + VAT.
Most boilers should be serviced once every 12 months. Annual servicing helps maintain safe operation, identify developing faults and may be required to maintain the manufacturer's warranty.
Common warning signs include pressure repeatedly dropping or rising, unusual noises, intermittent hot water, radiators failing to heat properly, leaks, fault codes and the boiler repeatedly switching itself off.
A boiler service usually takes 40 minutes to an hour, depending on if the boiler has been regularly maintained—if not, it may take longer.
It's generally not recommended, as boilers are complex and potentially dangerous systems. It's best to leave repairs to qualified professionals. Problems such as electrocution, gas leaks and water leaks could occur should the boiler be repaired incorrectly.
Boiler repairs can be completed within 15 minutes, however more complicated fixes can take up to 3-4 hours.
Turn off the boiler and water supply, and contact a qualified engineer immediately to assess and repair the issue. We may suggest opening the taps and opening the drain valve if there is one outside, or using a hose pipe if there is one internally on a radiator.
Regular maintenance, such as annual servicing, can help prevent many common boiler issues. It is advised to bleed radiators when required and ensure you have repressured the boiler if you have a sealed system. You can check for a pressure gauge on the boiler.
Check for obvious issues like power supply and thermostat settings. Ensure the gas supply is turned on and check for low water pressure within the boiler if you have a sealed system. If you can't identify the problem, contact a professional for diagnosis and repair.
It depends on the extent of the damage and the age of the boiler. We usually suggest that a boiler 10 years or older that requires a repair of more than £300.00, is beyond economical repair.
We work with the major boiler manufacturers commonly installed in UK homes, including Worcester Bosch, Vaillant, Ideal, Baxi, Viessmann, Glow-worm, Alpha and others.
