The number of call-outs to the London Fire Brigade (LFB) for carbon monoxide incidents has more than doubled in the past five years, according to new figures.
The gas, labelled a “silent killer”, cannot be detected through taste, sight or smell.
There were 1,714 emergency calls for firefighters between August 2024 and July 2025, LFB data showed.
Assistant Commissioner Pamela Oparaocha urged people to be “mindful of safety” when heating their homes in the colder months, especially when burning fuel unsuited for domestic use.
