Is It Safe to Charge an E-Bike Indoors? E-Bike and E-Scooter Battery Fire Safety at Home (Essex 2026)

E-bikes and e-scooters are a common sight in Thurrock, Stanford-le-Hope, Corringham and Upminster, and many are charged indoors. A new report from UCL and the charity Electrical Safety First, published on 19 October 2026, is a timely reminder that the lithium-ion batteries in these machines can be a serious fire risk if they are damaged, modified or charged in the wrong place. Here is what it found and what you can do at home. This guide is accurate as of 30 October 2026.

How common are e-bike and e-scooter battery fires?

According to the UCL report, fire and rescue services across the UK recorded 432 e-bike and e-scooter fires in 2025, and the London Fire Brigade alone responded to 228 e-bike battery fires that year. Cycling Industry News, reporting on the same research, notes that in 2019 there were just 10 such battery fires in the UK.

The research surveyed 637 food delivery riders, some of the heaviest e-bike users. Nearly three-quarters (73%) said they were worried about battery fires, and one in ten said their battery had overheated, which is an early warning sign of a potential fire.

Why do lithium-ion batteries catch fire?

Electrical Safety First explains that the main risk is thermal runaway: once a lithium-ion cell overheats, the reaction can become uncontrollable and irreversible, venting toxic fumes and leading to fire or even explosion. UCL adds that these fires can ignite explosively and are difficult to put out.

The report found the riskiest set-ups were converted pedal bikes and modified e-bikes. Around 21% of riders used a converted pedal bike, and common problems included exposed wiring, outdated or recalled batteries, motors above safe limits and several batteries wired together.

Is it safe to charge an e-bike indoors overnight?

The report highlights overnight and unattended charging as a hazard: 39% of riders surveyed charged overnight, and Cycling Industry News reports that 52% charged batteries in living areas. Bikes were also often charged near fire exits or next to radiators. Current safety guidance says:

• Follow the manufacturer's charging instructions and use the charger supplied for that battery.

• Don't leave batteries on charge for longer than recommended.

• Charge away from materials that catch fire easily, and away from heat sources such as radiators.

• Don't store or charge an e-bike or e-scooter near your front door, in a hallway you would need to escape through, or under the stairs.

• Never store or charge them in communal areas of flats.

• Where possible, store them in a shed or garage, unplugged and with the battery disconnected.

• Stop using a battery that is damaged, swollen or has overheated.

If a battery starts to smoke, hiss or catch fire, get everyone out, close the door behind you and call 999. Don't try to tackle it yourself.

What can an electrician do to make charging safer?

The battery and charger are the main risk, but the electrics you plug into matter too. If you would like to charge in a garage or outbuilding rather than in the house, a properly installed socket on a suitable circuit is a much better option than an extension lead trailed out of a window or through a door. Avoid plugging high-power chargers into overloaded or daisy-chained extension leads.

A few points worth knowing:

• In England, adding a new circuit is notifiable work under Part P of the Building Regulations. A registered electrician, such as an NICEIC Approved Contractor, can self-certify it for you.

• Sockets that may be used outdoors or to supply equipment outside should have suitable RCD protection.

• If your sockets feel warm, show scorch marks, or your circuit trips when a charger is plugged in, stop using them and get them checked.

• An Electrical Installation Condition Report (EICR) checks the condition of your wiring, sockets and protective devices. See our EICR page and electrical testing and compliance.

It is also a good time to test your smoke alarms. We covered that in our clocks going back guide.

What is the report asking the government to do?

UCL and Electrical Safety First recommend stronger regulation of batteries, chargers, conversion kits and online marketplaces, mandatory fire safety training for delivery riders, and communal charging hubs. As of today these are recommendations, not new rules.

I'm a landlord. What should I do?

If your tenants use e-bikes or e-scooters, it is worth making sure they know not to charge in hallways, under the stairs or in communal areas, and that your electrical installation is in good order. Private landlords in England already need an EICR at least every five years. Read our EICR guide for landlords, or contact us about commercial electrical work for blocks and shared buildings.

FAQ

Can I charge my e-bike from any normal socket?

Use the manufacturer's charger plugged into a sound, undamaged socket, ideally directly rather than through an extension lead. If the socket or plug gets hot, stop and have it checked.

Should I charge my e-scooter overnight?

Safety guidance advises against leaving batteries charging unattended or for longer than recommended, which makes overnight charging a risk.

Can you fit a socket in my garage or shed for charging?

Yes, we can install suitable sockets and circuits in garages and outbuildings, with the right protection and certification.
