Boiler repair London


Gas safety is vital, therefore, it is extremely important that you do not attempt to fix your boiler yourself. Instead, be sure to call out a gas safe registered engineer. Our engineers will gladly find and resolve the problems you are having with your boiler. Here are some of the common issues we find and resolve:

No heating or hot water

This is sometimes caused by low boiler pressure or inadequate water levels, faulty diaphragms/airlocks, broken motorised valves, problems with your thermostat(s). If this is the case, we may need to fit a new part.

Leaking & Dripping

There are many reasons why your boiler may be leaking water. The most common cause is an internal component such as air valves or pressure valve. if the leaking is around the pipes there may be corrosion.


Have you been hearing strange noises coming from your boiler? If your boiler sounds like a kettle, the chances are that limescale has built up in your system. In this instance, we may recommend our powerflushing service.

Pilot Light Fault

If your pilot light keeps going out, you may have a broken thermocouple that is stopping the gas supply, or perhaps there is something distinguishing the flame. Our boiler engineers will quickly identify the issue.

Low Boiler Pressure

Have a look at the pressure gauge on your boiler. Is the needle below 1? This may be caused by a water leak in your system or perhaps a faulty pressure valve. Low boiler pressure will stop your central heating system from functioning properly.

Thermostat problems

Over time you may notice that your thermostat has lost accuracy or has started to malfunction. If this is the case, it may be time to consider getting your thermostat replaced. Thermostats should only be installed by gas safe engineers.
