By following the official guidance from the Gas Safe Register and acting quickly, you can minimize the risk and get the help you need.
Open Windows and Get Fresh Air
If you suspect a gas leak, ventilate the area right away. Open all doors and windows to let fresh air in and help disperse the gas. This will reduce the risk of a fire or explosion by preventing gas from building up indoors.
Turn Off the Gas Supply (if safe)
Next, shut off the gas supply if you can do so safely. Locate the gas emergency control valve (the main shut-off valve, usually near your gas meter) and turn it off to stop the flow of gas. Only do this if the valve is easily accessible and it’s safe – if your meter is in a basement or hard-to-reach area filled with gas, leave it to the professionals. Cutting off the gas will help prevent any more gas from leaking out.
Avoid Flames and Sparks
While ventilating and shutting off the gas, make sure to eliminate any sources of ignition. Extinguish all naked flames and do not smoke. Just as importantly, avoid using electrical switches or appliances – don’t turn any lights or devices on or off, as even a small spark could ignite the gas. (This includes not using mobile phones inside the affected area.)
Call the National Gas Emergency Number
Once you have ventilated and shut off the gas, call the National Gas Emergency service immediately on 0800 111 999. Go outside or to a safe spot away from the leak to make the call. The emergency line is open 24/7 and will connect you to trained personnel who can advise you and send an emergency gas engineer to your property. If you use liquefied petroleum gas (LPG) from a tank rather than mains gas, call the emergency number provided by your LPG supplier
Wait for Help and Do Not Use Gas
Keep your household in fresh air (outside, if necessary) and wait for the emergency gas engineer to arrive. Do not turn the gas back on or use any gas appliances again until they’ve been checked and declared safe by a professional. If anyone is feeling unwell (for example, headaches or dizziness that could indicate carbon monoxide exposure), seek medical attention immediately.
After the Emergency: Inspection and Repairs
Once the immediate danger has passed and the gas leak is under control, you’ll need to address the cause of the problem. Contact My Heating Engineer Limited to inspect your system and carry out any necessary repairs. It’s crucial that any work on gas pipes or appliances is done by a qualified professional – only Gas Safe registered engineers are legally allowed to carry out gas work in the UK.
