Fire chiefs in the United Kingdom are urging immediate and stricter government regulation of the lithium-ion battery device market, particularly concerning electric bicycles (e-bikes) and scooters (e-scooters). According to the latest data published by the National Fire Chiefs Council (NFCC), failures of these vehicles lead to an average of several dozen severe fires nationwide each week. Experts warn that current inspection mechanisms are insufficient to filter out the dangerously poor-quality imported products flooding the market.
Dramatic Statistics: Rising Incident Rates in UK Cities
Aggregate data from UK fire departments clearly demonstrates that incidents linked to lithium-ion batteries are rising exponentially. Based on NFCC statistics, authorities in the UK are currently called out to fires caused by electric bikes or scooters an average of five times a week.
The situation is most critical in densely populated areas, especially the capital. According to the official report of the London Fire Brigade:
-
In 2025, London firefighters responded to a total of 192 e-bike and e-scooter fires.
-
Tragically, these incidents in the capital claimed three lives and left 51 people injured during the year.
Chiefs Demand Stricter Certification System
Mark Hardingham, Chair of the NFCC, stated that the current regulatory environment does not provide sufficient safety for consumers. Fire chiefs argue that the UK government should introduce a so-called “third-party approval system.”
In practice, this would mean that before an e-bike, e-scooter, or its corresponding battery and charging unit could be sold commercially in the UK, an independent, accredited testing body would be required to certify its safety. Currently, a significant portion of manufacturers and importers bring products into the country on a self-declaration basis (for example, self-applying CE or UKCA markings), which leaves ample room for the proliferation of shoddy alternatives.
The Risk Factors: Conversion Kits and Incompatible Chargers
Fire service investigations have revealed that the vast majority of these fires are not caused by factory-assembled e-bikes from reputable brands. The primary source of danger lies in e-bike conversion kits—used to electrify traditional bicycles—which can be purchased unverified on online marketplaces.
According to the analyses conducted, the most common triggers for catastrophic battery failures—which often involve explosive, intense combustion releasing toxic gases—are the following:
-
The use of substandard, often damaged, or factory-defective lithium-ion cells.
-
The use of incompatible battery chargers that do not match the voltage and current of the battery, directly leading to overcharging and “thermal runaway.”
Political Echo and Civil Coalition
The issue is already generating serious debate at the parliamentary level in the UK. The NFCC’s firm stance is supported by the British charity Electrical Safety First, which has previously drafted a proposed bill on the safety of electric vehicles. This initiative is officially backed by more than 100 different organizations, as well as numerous Members of Parliament.
The UK’s Office for Product Safety and Standards (OPSS) has stated that it has already begun reviewing a more comprehensive strategy regarding the safety risks of lithium-ion batteries and is currently in active consultation with fire service representatives on the necessary legislative steps.
