A new survey suggests millions of people across the UK would not know how to respond in the event of a gas or carbon monoxide leak.

The poll of 2,000 adults, carried out by OnePoll for British Gas ahead of Gas Safety Week (8-14 September), found only 51% felt properly informed of the risks of a gas leak. Less than half (48%) said they could confidently turn off their main gas supply, and just 29% of those who had experienced a carbon monoxide incident felt equipped to deal with it.

The research also revealed 47% of households have fitted a carbon monoxide alarm, while 45% admit they would not feel comfortable even testing one. A further 16% have never used a qualified engineer to carry out a household gas safety check.

Almost one in five (18%) said they wished they had been taught in school how to spot a gas leak.

British Gas engineer Faye Lackey warns that low public confidence in handling gas safety could put households at risk: “It’s clear that as a nation we are not as confident as we should be when it comes to gas safety. A few simple steps, such as booking an annual boiler service and installing a carbon monoxide alarm, can make a big difference.

“If anyone comes to your home to work on gas appliances, it’s essential that they’re on the Gas Safe Register. Installing a carbon monoxide alarm and checking it’s in good working condition regularly will help the overall safety of your home. Make sure it’s got a British Standard mark and check the lifespan of the detector so that you know when it’s time to replace it.

“If you smell gas and suspect a gas leak, you should take action immediately by calling the Gas Emergency Service at 0800 111 999. Turn gas off at the shut off valve, ventilate the area by opening windows and door and then evacuate the area quickly.”

Gas safety tips from British Gas

• Watch for warning signs such as yellow or orange flames, black stains near appliances, unusual smells, or excess condensation.
• Book annual checks for boilers, cookers and fireplaces through a Gas Safe registered engineer.
• Install an audible carbon monoxide alarm and test it monthly.
• Keep chimneys, flues, and vents clear and well maintained.
• Never attempt DIY work on gas appliances.

According to British Gas, maintaining robust safety practices is key not only to compliance but also to protecting households as the UK continues its transition to lower‑carbon heating systems.
