Gas Leaks

If you suspect a gas leak it is essential that you know what to do, it could save lives.

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.

What to do?

  • Open doors and windows to allow fresh air in.
  • Turn off the gas at the mains tap, which is usually near the meter. Move the handle a quarter turn until it’s at 90 degrees from the pipe to shut off the gas supply.
  • Leave the property.
  • Phone the National Gas Emergencies number on 0800 111 999. Only use a mobile phone from outside the property. The number is free and available 24 hours a day.
  • Follow the advice given by the emergency adviser.
  • Wait outside for a gas engineer to arrive.
  • If you are feeling unwell, visit your GP or hospital immediately. Tell them you may have been exposed to a gas leak or carbon monoxide poisoning.

What NOT to do?

  • Smoke, light a match or use any other naked flame.
  • Turn any electrical switches on or off.
  • Use doorbells, mobile phones or any other electrical switches, including light switches, which could cause a spark.

Detecting a gas leak – what are the symptoms?

  • If you’re suffering from these symptoms and suspect a leak, you should go outside immediately.

Gas leak prevention

There are lots of things you can do to be gas safe and help prevent a gas leak.

  • Any appliances that you own, or you have installed will be given a visual check only during the Gas Safety Check. It is your responsibility to have your own appliances serviced by a qualified, Gas Safe registered engineer.
