Boilers should never leak gas or oil. For safety, modern boilers burn gas or oil in a sealed combustion chamber. They bring in the oxygen needed to make the fuel burn, and then release the exhaust fumes safely back outside.
This sealed system keeps poisonous gases out of your home. But, very occasionally, things can go wrong.
What do I do if I have a boiler leaking gas?
If you have a boiler leaking gas, you might be able to smell this too. Other signs of a leak include black stains above or near the boiler. There may be excess condensation on your windows. Or the pilot light – the flame that indicates your boiler’s working – might be burning orange or yellow (rather than blue).
A boiler gas leak is very dangerous, especially as fumes from gases like carbon monoxide can be odourless. It’s why you should install a carbon monoxide detector in your home – and it’s law, in some instances.
If you suspect your boiler is leaking gas, immediately open all windows and doors and extinguish any naked flames – including cigarettes – then call the Gas Emergency Services free on 0800 111 999. Get more advice here.
