Whether you have a combi, gas or electric boiler, our engineers can repair it. You'll see your price online before you book, and you choose the date. When the engineer arrives, they test the boiler and find the cause. They explain the repair before starting, then fix it and replace any faulty parts. They'll explain what they did and anything to keep an eye on.
You don't need to know what's wrong before you book. Our engineers can also check your heating controls while they are with you.
A combi boiler heats water as you use it, so there is no tank to run out. When the hot water fails, the fault is in the boiler itself or its controls.
A common cause is the diverter valve. It switches the boiler between heating and hot water. If it sticks, you may get hot radiators but cold taps, or the other way round. Our Gas Safe engineer in Cwmbran will check the whole system, not just the boiler.
Lukewarm water, or water that runs hot and then cold, can point to a faulty sensor or low water flow. Low pressure can also stop a combi heating water.
Before you book, check the pressure gauge and the hot water setting on the boiler. Try a different tap too, as the problem may be with one tap only.
Combi boilers also need a good flow of water from the mains. If several taps run at once, the water may cool. That is normal, but a sudden change is worth checking.
A combi that heats the radiators but not the taps may also have a faulty sensor. Your engineer will test the valve, the pump and the sensors to find the cause.
Check that the boiler has power and the display is on. Then look for any code or warning light.

We've put together answers to common questions about boiler repairs in Cwmbran. For anything else, visit our boiler FAQ page.
Yes, all of them are. The law says anyone working on a gas boiler must be on the Gas Safe Register, and our engineers are. They are fully trained, DBS-checked and manufacturer approved. Opening up a gas boiler without the right training can put lives at risk, so always leave repairs to them.
Treat it as an emergency and dial 0800 111 999. That number reaches National Gas Emergency, who will send someone to make it safe. Turn off the gas at the meter, open the windows and avoid any sparks or flames. Then wait outside until they arrive.
It points to a specific fault. Some codes mean something simple, such as low pressure, which you can often fix by topping up. Others point to a part such as the fan or a sensor. Those need an engineer, so leave the casing on and arrange a repair.
A leak or a faulty part is the usual cause. Pressure often drops after bleeding radiators, which is normal. If it keeps falling with no obvious reason, water may be escaping inside the boiler. Our engineers can check the valves, seals and expansion vessel and fix whatever is causing it.
Yes, servicing is part of what we do. A boiler service in Cwmbran keeps your boiler running safely and efficiently. The engineer inspects the main parts, checks for leaks and tests the flame and gas pressure. A yearly service can spot problems early, before they become costly repairs.
