Four fire engines and around 25 firefighters tackled a fire in a flat in Arbuthnot Road, New Cross.
Part of a four-roomed flat on the first floor of a mid-terraced house was damaged by fire. There were no reports of any injuries.
The Brigade was called at 1152 and the the fire was under control by 1252. Fire crews from New Cross, Greenwich, Deptford and Old Kent Road stations were at the scene.
The cause of the fire is believed to be a faulty power control unit in a hoverboard.
A spokesperson for London Fire Brigade said: "Never leave items like hoverboards charging unattended and do not charge them overnight.
"It's also important to ensure your home is fitted with a working smoke alarm on every level of your home and the safest option is to have those linked together."
The Brigade’s top electrical safety tips are:
- Don't use imitation electrical chargers as they may be unsafe
- Make sure electrical appliances have a British or European safety mark when you buy them
- Unplugging appliances and chargers when you are not using them or when you go to bed helps reduce the risk of fire
- For plugs that do not come fitted to the appliance, always check you're using the right fuse
- Keep to one plug per socket
- If you use an adaptor, use a fused 'in line' type. The adaptor or extension lead will have a limit of how much power it can safely provide so be careful not to overload sockets
- Remember: scorch marks, flickering lights, hot plugs and sockets, fuses that low or circuit-breakers that trip for no obvious reasons could be signs of loose or dangerous wiring
