According to recent statistics, the London Fire Brigade (LFB) has experienced a significant increase in emergency calls regarding carbon monoxide incidents, with numbers more than doubling over the last five years.

Known as a “silent killer,” this gas is undetectable by taste, sight, or smell.

Data from the LFB indicates that between August 2024 and July 2025, there were 1,714 emergency calls related to this issue.

Pamela Oparaocha, the Assistant Commissioner, has emphasized the importance of safety when heating homes during the colder months, particularly when using fuels that are not intended for residential heating.

She noted, “While some alternative heating options may appear to save money, they can pose significant dangers.”

For example, she explained that burning treated wood, although it might be perceived as a budget-friendly choice, can emit harmful fumes and is more likely to scatter embers that could ignite other materials.

Carbon monoxide is a highly toxic gas generated from the incomplete combustion of fossil fuels.

Over the past six years, a total of 7,764 carbon monoxide-related incidents have been documented.

The LFB suggested that the rising living costs might play a role in this increase, as some households resort to hazardous heating practices or postpone servicing their appliances.

Ms. Oparaocha stated, “During the colder months, it’s understandable to seek economical ways to heat our homes, but it is crucial to prioritize safety.”

Recently, firefighters detected elevated levels of carbon monoxide in a food court on Kensington High Street in west London, prompting the building’s evacuation and ventilation before it was deemed safe.

The LFB recommends that carbon monoxide detectors be installed in all rooms containing fuel-burning devices and that these alarms are audible while individuals are asleep.

Additional information on safe heating practices and financial assistance for energy expenses can be obtained from local authorities and Citizens Advice.
