I think I can smell gas, what do I do?
If you think you have a gas leak or can smell gas, leave the house and phone the National Gas Emergencies number immediately on 0800 111 999. If you’re at home, and you can do it safely, turn off your gas supply. The gas mains tap should be beside your gas meter.
Why is my radiator cold?
If your radiator is cold at the top and hot at the bottom, there is most likely trapped air in the system. This can be resolved by simply bleeding the radiator to release the trapped air. Make sure you top up the pressure on your boiler if it’s a combi or a sealed system.
Another common cause for a cold radiator is a stuck valve. The thermostatic valve, usually a white control directly beside the base of the radiator, controls the flow of hot water to the radiator, but from time to time can become seized – often simply due to age.
Radiators that are cold at the bottom and hot at the top can be caused by a build-up of scale, rust and sludge over a period of time. A mixture of these materials can cause a blockage and obstruct the flow of water. To rectify this, you’ll need to flush your radiator.
