Walk down pretty much any street in East London these days and you’ll spot it: a delivery rider’s e-bike parked in the hallway, a fold-up e-scooter propped against the radiator, a charging cable trailing from the kitchen socket to somewhere near the front door. Two wheels and a battery have quietly become as normal as a bike shed used to be.
We’re not here to tell you to give it up — e-bikes and e-scooters are brilliant, and half of Dagenham seems to be commuting on one. But the battery that gets you to work is also the thing our colleagues in the fire service worry about most right now, and it’s worth five minutes of your evening to make sure yours is charging the right way.
Lithium-ion batteries are generally very safe. The trouble starts when one is damaged, counterfeit, charged with the wrong charger, or simply left to its own devices for hours on end. When one does fail, it doesn’t smoulder politely — it can ignite in seconds and burn with a ferocity that catches people out, producing thick, toxic smoke well before anyone notices a problem.
London Fire Brigade now attends a fire involving an e-bike or e-scooter lithium-ion battery on average every two days in the capital, and their figures show most of those fires start while the battery is charging. That’s not a reason to panic. It’s a reason to treat the charging point the same way you’d treat any other serious electrical load in your home.
Only ever use the manufacturer’s charger, or a genuine replacement bought from the manufacturer or a retailer you trust. A cheap generic charger picked up online to replace a lost one is one of the most common causes of battery fires — the small saving is not worth it.
Plug the charger directly into a wall socket. Don’t run it through a string of extension leads or a coiled cable reel, and don’t share that socket with three other things. If your hallway or garage doesn’t have a socket near where you actually want to charge, that’s a job for us, not a longer extension lead.
Never charge in a hallway, stairwell or anywhere near your only way out — if something does go wrong, that’s exactly the route you’ll need. And never leave a battery charging overnight or unattended while you’re out. Once it’s done, unplug it; there’s no need to leave it topped up on trickle charge for hours after it’s finished.
Look it over before you charge: no cracks, no dents, no swelling, nothing that’s been dropped or soaked. A battery that’s puffed up or misshapen has already failed — stop using it, don’t charge it again, and contact the manufacturer about safe disposal.

Most of what makes battery charging safer isn’t about the bike at all — it’s about the electrics behind the socket. A few things we’re regularly asked to sort out for e-bike and e-scooter owners across East London and Dagenham:
If you’re charging in a garage, porch or hallway that currently has no socket nearby, we can fit one properly — on its own circuit if the load calls for it — so you’re not relying on a lead stretched across a floor people walk through.
Every socket circuit should be protected by an RCD (residual current device), which cuts the power in a fraction of a second if something develops a fault. Older consumer units sometimes don’t have full RCD coverage — worth checking, especially if you’re charging something daily.
A working smoke alarm near your charging area buys you the early warning that makes the difference. We can fit interlinked alarms so if one goes off, they all do, wherever you are in the house.
If nobody’s inspected your wiring in the last decade, an Electrical Installation Condition Report checks your circuits, earthing and consumer unit are up to the job of the modern home you’re actually living in — chargers, e-bikes and all.
