Common Boiler Repair Faults

Our fully qualified engineers have tackled a host of gas repairs and boiler repairs in the past. Here are the most common boiler faults they have successfully addressed in London.

If your boiler makes banging noises, it means it’s working harder than usual in order to heat the water. The reason is simple. Water, especially hard water, contains calcium, magnesium, and other minerals that can solidify into limescale.

When limescale builds up, it creates a coating on the pipes that can sometimes obstruct the water flow. This makes a new boiler work extra hard, hence the noises. Our gas and heating engineers are well acquainted with this issue and know how to handle it.

Sometimes boilers can leak from different places and the reasons vary. It could be due to a corroded heat exchanger, loose joints, corroded pipes, loose joints, etc. Before the problem is addressed, the technician needs to identify the cause and trace back the dripping to its source.

The thermostat of your boiler system is a crucial part of the machine that helps to maintain the temperature to the desired setpoint. If it’s not working properly, you will find that the water isn’t as hot as you need it or that the heating around your home is turning on and off randomly. When the thermostat is malfunctioning, the first step is to check whether the correct settings are in place. If it turns out to be a different issue, the thermostat might have to be replaced.


Another common problem is the boiler’s inability to heat the water. There are many issues that can lead to this issue such as a faulty valve, blocked heat exchanger, or a faulty pilot light. If you are faced with such an issue, you should let our gas safe registered engineers inspect the area and detect the cause.

The circulation of water in the boiler works thanks to high pressure. When there is low water pressure within the system, it doesn’t function well. There may be a leak or something else might be going on. No matter the type of central heating repairs you need, we are here for you, equipped with the best tools and ready to restore hot water flow in an efficient manner.

Newer models typically use condensate pipes to eliminate waste gas. During the winter season, as outdoor temperatures drop, it increases the risk of your condensate pipe freezing. Modern devices will display this error on the interface. If this is the case, the pipe will have to be warmed up and defrosted.

This is usually an issue with older models that need a pilot light to ignite. If the light keeps turning off, it may be that the thermocouple is faulty. All things considered, you should check with a qualified specialist.

If the system won’t ignite, it could be an electrical issue you are dealing with. Make sure your boiler system is connected properly. You also want to check out other appliances around the home. If they don’t power on either, you should get an electrician to inspect the issue further and provide any electrical work as necessary.

If some of your radiators suddenly stop getting as hot as they should, this is an issue. Can you feel cold patches as you run your hand through the surface? Or is the radiator cold at the bottom? This means the heat is not evenly distributed as a result of sludge build-up or too much air within the devices.

FAQ on Emergency Boiler Breakdown and Repair

We strive to be as fast as we can. In most cases, our gas and heating engineers will do their best to visit you on the same day of your call, given that you are in an emergency.

It’s hard to tell as every job is unique. On average, the diagnostic will take between 20 and 45 minutes. Large-scale repairs may need more time to complete.

If you want to know how much your faulty boiler repair will cost, you need to get in touch with us and ask for a quote. The more details you provide, the more accurate the estimate will be. We do not have any hidden fees to worry about as we offer transparent pricing.

Of course. We can repair different boiler types regardless of their age and we always work hard to deliver a class service. However, you should keep in mind that we may not be able to find parts for certain appliances if they are 10+ years old. This depends on the heating suppliers and manufacturers themselves.

Most new boilers function well for 10-15 years as long as they are taken care of. If you have your boiler serviced on a yearly basis, this can help extend its lifespan.

If the season isn’t unusually colder than what you are used to getting and if the electric rates in your area have not been raised but you are still getting high electric bills, there may be a problem with the entire system. Further investigation is needed to detect a malfunctioning part.

If your radiators have cold spots, they will take longer to heat up. They may need cleaning on the inside, in which case a power flush will be most beneficial.
