You may have seen in the news recently that there has been an increase in the number of household fires caused by charging e-bikes and e-scooters. Most e-bikes and e-scooters are powered by lithium-ion batteries which are also becoming more widely used in many other household products, increasing the risk of a fire in the home. 

Since 2019 the London Fire Brigade has seen the number of fires caused by these lithium batteries rise from 8 in 2019 to 59 in 2021.  

If you own an e-bike or e-scooter, or another household item that is powered by this type of battery, it is important when charging them you do so safely.  There have been reports of batteries exploding leading to a rapidly developing fire. 

Below is some useful information on how to use these batteries safely in your home and how to dispose of them correctly. 


  • Follow the manufacturer’s instructions when charging and always unplug your charger when it’s finished charging. 
  • Ensure you have working smoke alarms.  
  • Charge batteries whilst you are awake and alert so if a fire should occur you can respond quickly. Don’t leave batteries to charge while you are asleep or away from the home. 
  • Always use the manufacturer approved charger for the product, and if you spot any signs of wear and tear or damage buy an official replacement charger for your product from a reputable seller. 
  • Do not cover chargers or battery packs when charging as this could lead to overheating or even a fire. 
  • Do not charge batteries or store your e-bike or e-scooter near combustible or flammable materials. 
  • Do not overcharge your battery – check the manufacturer’s instructions for charge times. 
  • Do not overload socket outlets or use inappropriate extension leads (use un-coiled extensions and ensure the lead is suitably rated for what you are plugging in to it). 
  • In the event of an e-bike, e-scooter, or lithium-ion battery fire – do not attempt to extinguish the fire. Get out, stay out, call 999. 


  • Avoid storing or charging e-bikes and e-scooters on escape routes or in communal areas of a multi occupied building. If there’s a fire, it can affect people’s ability to escape. 
  • Responsible Persons should consider the risks posed by e-bikes and e-scooters where they are charged or left in communal areas such as means of escape, bike stores and mobility scooter charging rooms. They may wish to offer advice to residents on the safe use, storage and charging of these products. 
  • Store e-bikes and e-scooters and their batteries in a cool place. Avoid storing them in excessively hot or cold areas. 
  • Follow manufacturer’s instructions for the storage and maintenance of lithium -ion batteries if they are not going to be used for extended periods of time. 


  • Buy e-bikes, e-scooters and chargers and batteries from reputable retailers. 
  • Many fires involve counterfeit electrical goods. Items which don’t meet British or European standards pose a huge fire risk and while genuine chargers (or battery packs) may cost more, it’s not worth putting your life at risk and potentially destroying your home by buying a fake charger to save a few pounds. 
  • If buying an e-bike conversion kit, purchase from a reputable seller and check that it complies with British or European standards. Take particular care if buying from online auction or fulfilment platforms. Also be aware that if buying separate components, you should check that they are compatible. 
  • Register your product with the manufacturer to validate any warranties – batteries are usually included in warranties. Registering makes it easier for manufacturers to contact you in the event of safety or recall information. 
  • Check any products you have bought are not subject to a product recall. You can do this but checking Electrical Safety First’s website or the government website

Damage and disposal 

  • Batteries can be damaged by dropping them or crashing e-bikes or e-scooters. Where the battery is damaged, it can overheat and catch fire without warning. Check your battery regularly for any signs of damage and if you suspect it is damaged it should be replaced and should not be used or charged. 
  • If you need to dispose of a damaged or end of life battery, don’t dispose of it in your household waste or normal recycling. These batteries, when punctured or crushed can cause fires in bin lorries, recycling, and waste centres. Your e- bike or e- scooter manufacturer may offer a recycling service. Alternatively check with your local authority for suitable battery recycling arrangements in your area.
