There has been a 20% increase of smoking-related fires in London homes, the city's fire brigade has warned.
There were 315 fires between 20 March and 22 July due to cigarettes not being disposed properly, London Fire Brigade said.
It compares to 260 in 2019 during the same period.
Deputy assistant commissioner Charlie Pugsley said: "Lots of people have been working from home and staying indoors more, which might explain why we have seen a spike in smoking-related fires."
On 28 May, four people were rescued and more than 100 residents escaped when a blaze ripped through a block of flats in Hadleigh Close, Bethnal Green.
Investigations revealed the fire was caused by the unsafe disposal of a cigarette.
Mr Pugsley added: "If you can’t quit, it’s always safer to go outside to smoke, but make sure cigarettes are put right out and disposed of properly.”
