Boiler Repairs

No heat or hot water

Potential causes include broken diaphragms and airlocks, failure of motorised valves, issues with the thermostat or low water levels. A good place to start is to check if your boiler is not working because of an issue with boiler pressure or your thermostat.

Leaking and dripping

A variety of issues could cause your boiler to leak water. It will depend on where the water is leaking from to determine the cause – however you should never try to fix a leaking gas boiler yourself, always call out a Gas Safe registered engineer.

The most common cause is a broken internal part, such as a pump seal or pressure valve. If the leak is coming from the pressure valve it may be a case that your boiler pressure is too high. If it is coming from the pump seal, it may have become worn out and need replacing.

You may also find your boiler is leaking around the pipes or tank – this can be a result of corrosion or in some cases where the system has not been fitted properly. In any case, we recommend calling out an engineer who will be able to diagnose and fix the issue for you (in in the worst case advise if you need to replace your boiler).

Strange noises

Air in the system is a common cause, alternatively it could be that the water pressure is too low, or it is kittling. Imminent pump failure, particularly in older systems, could also be responsible for strange banging noises.

Could be a broken thermocouple which is stopping the gas supply, a draught blowing the pilot light out or a deposit built up in the pilot light.

It is worth checking that there are no issues with your gas supply before trying to reignite a pilot light – for example if your gas stopcock is on but your boiler is receiving no gas, or if none of your other gas appliances are working you should contact your gas supplier.

Losing pressure

If your boiler pressure drops too low, your central heating system may not function properly. To check a boiler’s pressure level, simply look at it is built in pressure gauge – if it is below 1 you may have an issue. There a few reasons why this may be happening: a water leak in the system, the pressure relief valve needs replacing or as a result of recently bleeding radiators.

The first thing to do is check for a visible leak in the system. If you find one you should call a registered engineer, if not you could try depressurising the system. Only do this if you feel comfortable doing so (if not call out an engineer) and ensure you follow your heating systems’ manual.

Radiators not heating up

You might find that not all your radiators are getting hot or that only the bottom section is heating up. This can be down to a few reasons but the two most common are sludge or air build up in the system and unequal distribution of heat. If only the bottom of your radiator is getting hot, you may need to bleed it. This is straightforward and does not require an engineer (unless you do not feel able to carry out the task yourself).
