A devastating fire that tore through a block of flats in Cornwall Avenue, Bethnal Green on Tuesday, April 9, is believed to have been caused by a lithium-ion battery used in an e-bike or e-scooter, according to London Fire Brigade (LFB).

The fire, which broke out just before 11:40pm, prompted a large-scale emergency response with eight fire engines and around 60 firefighters from Shadwell, Shoreditch, Bethnal Green, Poplar, and nearby stations attending the scene.

Dozens Rescued, 11 Hospitalised

Firefighters rescued seven people using fire escape hoods, while 17 were treated at the scene by London Ambulance Service crews. Eleven people, including at least one child, were taken to hospital. One man reportedly jumped from a second-floor window to escape the flames but was unhurt.

Thankfully, it has since been confirmed that the condition of the most seriously injured person is no longer life-threatening.

Due to the damage and safety concerns, around 50 residents were relocated to a nearby library, and the housing association responsible for the building arranged emergency accommodation and support.

Lithium-Ion Batteries to Blame

Following a thorough investigation, LFB determined the most probable cause of the fire was the failure of a lithium-ion battery connected to an e-bike or e-scooter.

“This would have been a terrifying ordeal for all those inside this building,” said Deputy Assistant Commissioner Richard Field.
“Firefighters demonstrated great courage bringing multiple people to safety.”

He added that multiple e-bikes and e-scooters, some modified or second-hand, were found inside the flat, contributing to the rapid spread of the fire.

A Growing Fire Risk

The incident highlights the increasing risk posed by lithium-ion battery fires, which have surged in recent years.

“These fires are ferocious and produce extremely toxic smoke,” warned Commissioner Field.
“If you own an e-bike or e-scooter, charge it safely — never while sleeping or near escape routes, and always with the correct charger.”

Local Response and Campaigns

Tower Hamlets Executive Mayor Lutfur Rahman praised the response and reaffirmed the council’s commitment to fire safety through its #ChargeSafe campaign.

“We’ve halved the number of e-bike battery-related fires in the borough, but more needs to be done. If you use one, follow the guidance to protect yourself and others.”
