Common Signs That You May Need A Boiler Repair Service


If you encounter a boiler breakdown or your boiler experiences a fault, it can sometimes be a stressful experience. Boilers are by far one of the most dependable heating systems for your home and commercial premises. Although boilers are meant to withstand wear and tear and are built for longevity, you can always encounter an issue with your boiler.


Ensuring that your boiler is running efficiently and is safe is vital for your home and place of work. Having a broken boiler puts your family at risk, as well as your employees, as dangerous gases could easily spread and go undetected. Often you will be unable to smell the gas that is leaked or notice the potentially dangerous issue that may be worsening.


With over 40 years of experience in providing a first-class service for boiler repair in Cardiff and South Wales, we are experts in recognising the common signs that your boiler may be in need of repair. Here are some of the most common signs that our fully qualified gas engineers have found to warrant our boiler repair service:


  • No heating or hot water is available from radiators or taps
  • Odd noises from the boiler, such as banging, whistling or gurgling
  • The pilot light has gone out or is an unusual colour
  • The thermostat is not working correctly and not showing the correct temperature
  • Low boiler pressure due to a leak or a new relief valve being required
  • Odd smell emitting from the boiler or around the property
  • Water leaking or rust appearing around the boiler
  • Energy bills are getting higher than normal


We strongly recommend having your boiler annually serviced by a team of specialists such as ourselves to ensure that you keep your family, employees, and property safe from any of the risks that can occur with a damaged boiler.

What Are The Risks Of A Broken Boiler?


Unsurprisingly, a broken boiler can be very inconvenient and can leave you without any hot water or heating in your home or office premises. However, a broken boiler also has the potential to become a harmful health risk as a broken boiler if left unchecked, could cause monoxide poisoning, fires or even explosions. If you do happen to suspect a gas or carbon monoxide leak from your boiler, open all the doors and windows in your home and switch off your gas supply located at the meter immediately. You should not use any kind of naked flame, electrical switches or any other ignition sources in your home or office.


It’s best to contact the National Gas Emergency helpline right away:

England – 0800 111 999

Simple Checks To See If Your Boiler Is Broken

We strongly advise against you taking on a boiler repair yourself and should always seek a professional repair service to be carried out by qualified and Gas Safe registered engineers, such as the team here at Eric Collier & Son. However, there are some simple checks that you can carry out yourself before calling a heating engineer. If you require boiler repair in Cardiff, call us now on 02920 508711.

One of the first checks that you can do for your boiler is to see if there is any supply of electricity. Check to see if it’s plugged in and if it is but still has no power then contact your electricity provider. If you have experienced a power cut, there is a good chance that your boiler may just need a reset again.

If you suspect that your boiler is broken, one of the easiest checks that you can carry out is to check if there is any water supply in your home by simply running a tap. If there is no water running then your boiler may be broken.

For those with a gas boiler, if you have other gas-run appliances in your home, such as a stove, you can check to see if they are working. If the gas stopcock is switched on but there is now gas pulling through, then this will mean that there is a gas supply problem.

If you think your boiler is broken, checking the pressure gauge is always a good idea. When checking, you should take a look at the manual to see the correct pressure for your boiler. If the pressure is at the right level, then you may have a gas supply problem, which is when you should call a Gas Safe engineer to come and take a look.

If your boiler is running fine and fires up properly but your radiators don’t seem to be heating up then you can try bleeding them. Air can become trapped in radiators which are very common and bleeding them allows the trapped air to escape. This is possible to do by yourself and won’t need the assistance of a professional heating engineer. When bleeding your radiators, always ensure that your heating is switched off before as hot water could spray out.

Most modern boilers will contain a digital display pad where you can check to see if there are any error codes displaying if you suspect that your boiler is broken. Each boiler will have different error codes, usually displaying letters so you should always refer to the boiler manual.
