Vape batteries have been found to have caused house fires and insurers may not pay out
The amount of house fires linked to vapes have increased by over 100% in the last two years, according to experts.
With a surging number of people vaping in Britain, MoneySuperMarket investigated the link between the device and fires at home.
Vapes might be small, but home insurance experts said the risk they pose is anything but. Powered by lithium-ion batteries, these devices can overheat, explode and cause serious house fires – and the problem is only getting worse.
House fires caused by faulty, damaged, or improperly charged lithium-ion vape batteries are particularly dangerous as they burn hotter and spread faster causing extensive damage and release toxic gases that put lives in danger.
When a lithium battery is damaged, overheats or short-circuits, it can trigger a chain reaction that causes it to burst into flames at up to 1,000°C. These fires spread fast, release toxic fumes and produce deep-seated flames that are difficult to put out due to the battery’s core being surrounded by other parts. In some cases, they even reignite hours or days later because of residual chemical energy.
Alicia Hempsted, Home Insurance Expert at MoneySuperMarket, explains: “Many vapers don’t realise that using the wrong charger, leaving a vape on something flammable, like a bed while charging, or using a damaged battery can quickly escalate into a fire.
Most home insurance policies cover fire damage, but it’s important to know that if the fire is caused by negligence, improper charging, or the use of counterfeit products, your claim could be delayed or even rejected.
Insurance companies may not cover incidents that occur due to preventable risks, leaving homeowners with the financial burden of repairs, lost belongings, and potential temporary relocation.
Alicia added: “A fire in your home can be devastating, both emotionally and financially.
“While home insurance can offer a safety net, it’s not a guarantee that every claim will be accepted – especially if negligence is involved. Taking proactive steps, like using the correct charger, checking your vape for damage, and safely storing batteries, can help prevent a fire before it starts.”
How to Protect Your Home from Vape Fires
Battery Safety
- Avoid metal contact: Never carry vape batteries loose in a pocket or bag with coins or keys, as this can cause a short circuit.
- Store spares properly: Keep removable or spare batteries in a plastic case, away from children.
- Check for damage: If a battery is leaking, overheating, or has dents, stop using it immediately.
- Dispose of old batteries safely: Check with your local authority for proper disposal options and never put used batteries in the bin.
Charging Safely
- Use the right charger: Only charge your vape with the manufacturer’s charger, not a phone or tablet charger.
- Don’t charge overnight: Never leave your vape charging unattended, especially while sleeping.
- Unplug when full: Overcharging can cause overheating and fire risks.
- Charge on a safe surface: Keep your vape on a flat, fire-resistant surface, away from flammable items.
Buying Safe Vape Equipment
- Buy from reputable sellers: Cheap, fake, or second-hand vape products may lack safety features.
- Use the correct batteries: Not all batteries are safe for vaping – always use those recommended for your device.
- Don’t mix batteries: Never use old and new batteries together or mix brands.
- Choose vapes with safety features: Look for devices with protection against overcharging, button locks, and vent holes.
