How to fix a broken boiler

Experiencing problems with your boiler and trying to determine the route of the issue can be challenging, but fixing your boiler doesn’t need to be stressful.

The first step to fixing your boiler is to identify the problem and carry out significant checks. Trying to diagnose the problem yourself can save you time and money. Here is a step-by-step guide to fixing a broken boiler before you call out a registered engineer. 


Is your pilot light on? 

Checking that your pilot light is on should be one of the first things you do when experiencing issues with your boiler. Without this light, the flame cannot ignite the boiler’s gas supply. If it is off, try and relight it yourself.

Follow the instructions on your boiler’s instruction manual to the letter. If these actions don’t shed any light on the issue, go online and visit a forum for advice. Do not attempt to fix this issue without an experienced engineer.

Doing so could result in an expensive fee should you make the problem worse and could invalidate an insurance policy if you have one. 


Check the pressure 

Diagnosing a problem with your boiler can sometimes be as simple as checking your pressure gauge. The number you should be looking for is around 1.0 or 1.5. If the boiler pressure falls below this number, refer to your manual before you take action, as every boiler is different.

Check your radiator valves for signs of a leak, as this could be the cause of low boiler pressure. Just because you can’t see signs of a leak doesn’t mean there isn’t one, it may simply mean you may have to put the problem into the hands of a boiler specialist.


Check your thermostat 

Before you rack up the charges by calling out a professional, inspect the thermostat itself. A broken thermostat doesn’t necessarily mean that your boiler is broken; it could simply indicate that your thermostat is faulty and may need replacing. Begin by ensuring your thermostat is on and that the temperature is turned up to the correct degree. 


Call a qualified engineer 

If you have done all of the DIY checks mentioned above to no avail or you are simply not comfortable attending to the issue yourself, it is time to call out the professionals. If you took out insurance with your boiler at the time of purchase, the insurance company should be able to organise assistance within 24 hours. If you do not have boiler insurance, you will have to research local repair companies online to find an engineer yourself.

When searching for a boiler engineer, always check that they hold the relevant qualifications required. Research reviews online or get a recommendation from friends or family and always ask for a quote to ensure you get the best deal. Be wary of hidden costs, for example, a call out charge, collection of parts or any costs associated with a return visit to fix the problem.
