Important: what you should do if your boiler smells like gas

Please note, we can only give you basic advice on this page. Make sure you use the right tools and protective equipment to avoid hurting yourself or damaging your home. Always consult a professional for more complex repairs.

If you smell gas from your boiler, you should immediately report a suspected gas leak to the National Gas Emergency Helpline by calling 0800 111 999.

You should also adhere to the following guidelines to maintain safety whilst you wait for a Gas Safety Engineer to arrive:

• Make sure all doors and windows are open

• Switch off your gas supply and ensure it stays off until you have been informed that it is safe to switch back on by a Gas Safety Engineer

• Don't operate electrical switches

• Don't smoke cigarettes

• Don't light naked flames (such as candles, matches or cigarette lighters)

• Avoid turning on lights or any devices connected to the electrics

• If you feel unwell, visit your GP or hospital immediately and let them know that you may have been exposed to carbon monoxide

What could cause my boiler to smell like gas?

If you're wondering why your boiler smells like gas, there are a multitude of reasons that could be causing it. If you have home emergency boiler cover but recognise signs of a potentially serious gas leak, for example, a rotten egg smell, we always recommend contacting a gas safety specialist. A specialist can provide a proper diagnosis in case a dangerous situation were to occur.
