In 2026, UK airport security and airlines have a strict mandate: vapes and e-cigarettes must NEVER be placed in checked baggage. This is due to the fire risk posed by lithium-ion batteries in the cargo hold. If a vape is detected in a checked bag during the X-ray screening process, the bag will likely be pulled for a manual search, and the device will be confiscated. In some cases, this can lead to delays in your bag reaching the aircraft. You must carry your vape device on your person or in your hand luggage, and all e-liquids must be placed in your clear, one-liter liquids bag. While the UK has implemented a ban on disposable vapes as of mid-2025, refillable and rechargeable kits are perfectly legal to carry through security as long as they are powered off and stored correctly.
