Firefighters have issued safety advice after an e-bike battery exploded and caught fire at a block of flats on Beaumont Street in Marylebone.

A small part of a sixth floor balcony was damaged by fire along with lithium batteries that were being charged for a converted e-bike. Two people who were inside the flat were treated at the scene by London Ambulance Service crews for smoke inhalation.

The fire is being treated as accidental and is believed to have been caused by the catastrophic failure of lithium batteries.

Fires involving e-bikes and e-scooters, and the lithium batteries that power them, have become one of London’s fastest-growing fire risks in recent years.

A London Fire Brigade spokesperson said: “In this latest incident, the batteries had been detached from the bike and were being charged outdoors on the balcony, Whilst we wouldn’t recommend a balcony as a location to charge, the fact the batteries were not being charged inside the flat undoubtedly limited the amount of damage caused to the property. Crucially, it also meant the occupants’ escape route was not impeded.

“However, this fire highlights the risks of using modified e-bikes, which have been converted from a normal pedal cycle by having batteries fitted, and may not have been carried out by a professional or competent person.

“The owner of the bike was also aware that they were using a charger that is the subject of an official product recall as the product presents a serious risk of fire.

“If you own a product that has been recalled, it is vital that you stop using the product and to dispose of it safely, by following advice from your local authority.”

The Brigade’s Control Officers received around 10 calls about the fire.

The Brigade was called at 2302 and mobilised six fire engines and round 40 firefighters from Euston, Soho, Paddington and Kentish Town fire stations to the scene. A 32-metre turntable ladder was also deployed as an observation tower, providing the Incident Commander with a greater situational awareness of the incident. The fire was brought under control by 2337.

E-bike or e-scooter top safety tips

  • Never block your escape route with anything, including e-bikes and e-scooters. Store them somewhere away from a main through route. Our advice is to store these items in a safe external location if possible, such as a garage or a shed. 
  • Always use the correct charger, otherwise the risk of fire increases, and buy an official one from a reputable seller.  
  • Do not attempt to modify or tamper with your battery. Always follow the manufacturer’s instructions.  
  • Converting pedal bikes into e-bikes using DIY kits bought online can be very dangerous. They pose a higher risk of fire. Get a professional or competent person to carry out the conversion and make sure to buy a battery from a reputable seller and that it is not second-hand. 
  • Check your battery and charger meets UK safety standards.  We have particular concern where batteries have been purchased from online marketplaces and when they've been sourced on the internet, which may not meet the correct safety standards.  Consumers buying any product can check that the item displays a UKCA or CE mark that ensures that the products meet UK and EU safety, health or environmental requirements. If buying online, buy from a UK supplier.
  • Watch out for signs that the battery or charger aren’t working as they should – e.g. if the battery is hot to the touch or has changed shape.  
  • Let the battery cool before charging. Batteries can get warm during their use and it is advisable to allow them to cool down before attempting to re-charge as they could be more susceptible to failure if overheated. If you are charging batteries indoors, please follow our advice on safe charging. 
  • Unplug your charger once it’s finished charging. Always follow manufacturers’ instructions when charging and we would advise not to leave it unattended or while people are asleep.
  • Fit alarms where you charge. Ensure you have smoke alarms fitted in areas where e-bikes or e-scooters are being charged and make sure they are tested regularly. You can quickly and easily check your home by visiting our free online home fire safety checker tool
