FAQ:
How do I know if my boiler needs repairing?
There are a few clear signs that your boiler might need repairing. The most obvious one is when you have no heating or hot water, or the temperature keeps dropping for no reason. Another common issue is when the boiler keeps switching itself off or showing an error code on the display. Unusual noises like banging, gurgling or whistling can also mean there’s air trapped in the system, low water pressure, or a failing pump.
You might also notice the radiators aren’t heating evenly, or the boiler pressure keeps dropping below one bar. Leaks or puddles around the unit are another strong sign something’s wrong usually from a faulty seal, valve, or internal corrosion.
In short, if your boiler starts acting differently making noises, losing pressure, or giving inconsistent heating it’s time for a repair check. Catching issues early prevents bigger, more expensive damage later and keeps your system running efficiently and safely.
Do you offer emergency boiler repairs?
What types of boilers do you repair?
We repair all main types of boilers used in UK homes as: combi boilers, system boilers, and regular (conventional) boilers. Our engineers are trained and experienced with leading brands like Worcester Bosch, Vaillant, Ideal, Baxi and more.
Combi boilers are very common in London flats and smaller houses. They heat water directly from the mains, so when they fail, you usually lose both hot water and heating at once. We deal with issues like ignition failures, low pressure and faulty diverter valves on these units all the time.
System boilers and regular boilers are often found in larger properties with cylinders and water tanks. Repairs on these systems can involve pumps, valves, or expansion vessels. We also handle problems like leaking pipework or airlocks that stop hot water circulation.
Whether your boiler is modern or older, our engineers carry diagnostic tools to identify faults quickly and safely. We only use manufacturer-approved replacement parts to ensure reliability. In most cases, repairs can be completed the same day, provided no special parts are required.
Is it safe to repair a gas boiler?
Gas boilers should only ever be repaired by Gas Safe registered engineers. It is not safe to attempt repairs yourself or to use someone who isn’t qualified. Gas systems can be dangerous if handled incorrectly, leading to gas leaks, carbon monoxide poisoning or even explosions.
A Gas Safe engineer is trained to work safely with gas appliances and understands how to isolate faults without risking your home’s safety. We check for leaks, test combustion levels and ensure the flue is venting properly before and after any repair.
During a professional repair, the engineer will inspect all safety controls, seals and connections to confirm the boiler is operating correctly. Once the work is complete, they’ll test the system and ensure it meets safety regulations.
If your boiler ever smells of gas, shows a yellow flame, or causes headaches or dizziness in the house, turn it off immediately, open windows and contact a Gas Safe engineer.
Keeping safety first means using only qualified professionals. It protects your home, ensures compliance with legal standards, and keeps your boiler warranty valid.
