Looking for fixed price boiler repairs in Merthyr Tydfil? We aim to get to you the same day or the next day wherever possible. Our repair guarantee comes with all work. Typical repairs include new pumps, fans, valves, sensors and circuit boards.
We cover combi, gas and electric boilers, from new models to older ones. It takes a couple of minutes to book online and pick a date. An engineer visits your home and checks the boiler to find the fault. They then repair the boiler and check it is working safely. If you have questions, your engineer will answer them before leaving.
We also repair the pipework and valves connected to your boiler. It helps to have the boiler's make and model to hand when you book.
Boilers make some noise when they run, but loud banging, gurgling or whistling is a sign of a fault. The type of sound often shows where to look.
Gurgling usually means air in the system or a partly frozen condensate pipe. Bleeding the radiators can let the air out. Check the pressure afterwards, as it often drops. If the fault won't clear, leave the casing on and let a boiler engineer in Merthyr Tydfil take a look.
Banging or knocking can come from limescale on the heat exchanger. The scale makes water boil in one spot, which causes the noise. This is often called kettling.
Whistling can point to low water flow, a pump problem or a blocked filter. A humming sound may come from the pump or the fan.
Don't ignore a boiler that has become louder. Noise often comes before a breakdown. Fixing the cause early is usually simpler.
A noisy boiler may also be using more energy than it should. Limescale and sludge make it work harder to heat the same water. Your engineer can tell you what is causing the noise and how to fix it.
Never take the boiler casing off yourself. The parts inside should only be handled by a Gas Safe engineer.

Got a question about boiler repairs in Merthyr Tydfil? We've answered some common ones below. More questions are answered on our boiler FAQ page.
That depends on your boiler. Codes differ between makes and even between models. Note the code and check your manual, which explains what each one means. Try one reset. If the code returns, our engineer will use it as a starting point to trace the fault and repair it.
Most of the time, it's better to repair. Our approach is simple: repair wherever it makes sense. Your engineer will find the fault and explain the cost of putting it right. If several parts have failed on an older boiler, they'll tell you, so you can weigh up a replacement.
Yes. Every engineer we send is Gas Safe registered and fully qualified. That matters, because unsafe gas work can put lives at risk. Our engineers are also DBS-checked, so you can feel at ease letting them into your home. Please don't attempt a gas repair yourself, even a small one.
Get everyone out and phone 0800 111 999 straight away. This is the free National Gas Emergency line, open 24 hours a day. If it's safe, turn off the gas at the meter and open the windows first. Don't use light switches or naked flames until the emergency engineer says it's safe.
It depends on the repair needed. Clearing a fault code can be quick, but replacing a part such as a diverter valve takes longer. Your engineer will explain the timing before starting. They test the boiler once the work is done, so you know it is working safely.
