lithium-ion battery fire risk

    The insurer, Aviva, has urged people to consider the lithium-ion battery fire risk in their homes after seeing an increase in customer claims related to them.

    The findings at a glance

    In research commissioned by Aviva to further investigate public feeling and experience with lithium-ion battery fire risk, there are many worrying statistics.

    These include:

    • One in nine Brits have suffered a fire (11%) or explosion (11%) in their home due to a lithium-ion battery or device
    • one-in-ten (9%) have experienced the scorching of a surface where a lithium-ion battery or device was charging
    • two-in-ten (20%) have experienced a battery or device overheating at some point
    • two-in-five adults (41%) don’t know what a lithium-ion battery is
    • two-fifths (42%) are unaware of the fire risks associated with charging them
    • seven-in-ten adults (71%) don’t know the warning signs of a lithium-ion battery that’s about to fail
    • less than three in ten adults (27%) unplug their device once it’s fully charged
    • almost one-in-ten (9%) leave their mobile phone charging while they’re not present in their property
    • more than one in ten individuals (13%) – that’s over seven million Brits – don’t have a smoke alarm or any other fire safety devices fitted in their homes

    This data shows that action is needed urgently.

    Education and action from leading companies and regulating bodies is needed to improve these figures and help protect families and homes.
