Can You Take Vapes Through Airport Security?
Yes. Vaping devices are completely routine at UK airport security. Security staff see hundreds every day. Here is exactly what goes in the tray, what goes in the liquids bag and the common mistakes that cause unnecessary delays.
Yes, you can take vapes through airport security. The Civil Aviation Authority (CAA) permits vaping devices through UK airport security checkpoints in hand luggage only. Security staff at major UK airports process hundreds of vapes every single day and treat them as completely routine electronic items. Your device goes in the security tray alongside your phone and laptop. E-liquid goes in your clear 1-litre liquids bag. Provided you have packed correctly, the process takes seconds.
Exactly What Goes Where at the Security Checkpoint
The single most common cause of delay at security for vapers is confusion about which items go in the tray and which go in the liquids bag. The rules are straightforward once you understand the logic: anything with a battery is an electronic device and goes in the tray; anything containing liquid follows the liquids rule and goes in the bag.
Security tray (with phone and laptop)
- Vape device or pod kit (switched off)
- Box mod or vape pen
- Spare batteries in hard protective case
- Vape charger and cables
- Empty tanks or empty refillable devices
Clear 1-litre liquids bag
- E-liquid bottles up to 100ml each
- Prefilled pods or cartridges with liquid inside
- Disposable vapes (contain e-liquid)
- Refillable pods with liquid inside
- Tanks containing e-liquid
The device body itself, when it contains no liquid and has an empty tank, does not need to go in the liquids bag. It goes in the tray. Only items that contain liquid go in the bag. A common mistake is putting the entire vape kit into the liquids bag, which makes it harder for the X-ray operator to clearly identify the battery-containing device and can trigger a manual inspection.
Vapes are completely routine items at UK airport security. Staff see hundreds every day and are fully trained to identify them.
Battery rule: device in tray. Liquids rule: e-liquid and pods in clear 100ml bag. These are the only two rules that apply.
UK airports with confirmed post-security vaping areas. Always assume there is none and plan accordingly.
Common Mistakes That Cause Delays
Vape in the checked bag
The most serious error. Baggage scanners detect the battery and your suitcase is pulled from the system. The device is confiscated and your bag may be delayed or miss the flight entirely.
E-liquid over 100ml in hand luggage
Any bottle over 100ml will be confiscated at the checkpoint regardless of how full it is. Even a 120ml bottle that is nearly empty will not pass through. Decant into smaller bottles or pack larger quantities in your checked bag.
Partially filled tank
Pressure changes at altitude cause air inside the tank to expand, pushing liquid through the airflow holes. This will make a mess of your hand luggage. Either empty the tank completely or fill it to the very top before going through security.
Loose spare batteries
Spare external batteries loose in a bag with coins or keys risk a short circuit. This is a fire safety issue and can result in the batteries being confiscated. Always use a hard battery case or tape the terminals.
What Happens If Security Asks About Your Vape?
Security staff may occasionally ask to inspect a device if the X-ray image is unclear. This is routine procedure and not cause for concern. They will ask you to remove the device from the bag for a closer look, possibly swab it for trace substances and then return it. The process takes under a minute. Be cooperative, explain clearly what the device is and where the e-liquid is packed, and you will be waved through promptly.
If you are asked to demonstrate that the device is switched off and cannot fire accidentally, simply show the officer the device. Most modern pod kits have a five-click lock function. Having your device switched off or locked before you reach the checkpoint is good practice.
Can You Vape in the Airport Terminal After Security?
In most UK terminals, no. Vaping is treated the same as smoking in UK airports. It is generally restricted to designated outdoor smoking areas only, which are typically located before you pass through security. Only 11 of the 23 major UK airports have confirmed post-security vaping or smoking areas. At airports without one, you would need to exit the terminal, vape and re-clear security, which is time-consuming and risky before a flight. Plan to use your nicotine product of choice before you enter the security queue.
If you need to manage nicotine during a long wait or the flight itself, nicotine pouches from Purple Haze MK in Milton Keynes are the ideal solution. No device, no liquids, no battery, and they can be used discreetly anywhere in the terminal and often during the flight itself.
Pack your vapes near the top of your hand luggage rather than buried at the bottom. If security staff ask to inspect your device, you can retrieve it quickly without unpacking everything else. This keeps the queue moving and shows that you are a prepared and organised traveller.

Frequently Asked Questions
Will my vape set off the airport metal detector?
Modern airport security uses X-ray scanners rather than traditional metal detectors for carry-on items. Your vape will be identified on the X-ray as an electronic device containing a battery, which is exactly what it is. This is a normal reading and will not cause a problem provided you have packed correctly with your device in the tray and e-liquid in the liquids bag.
Can they confiscate my vape at security?
Security staff can confiscate any item that violates security rules. A correctly packed vape in hand luggage will not be confiscated. Items that are confiscated are typically devices found in checked baggage, e-liquid bottles over 100ml presented at the security checkpoint or batteries that are not properly protected.
Do I need to declare my vape at security?
You do not need to proactively declare a vape any more than you would declare a phone or laptop. Simply remove the device from your bag and place it in the tray alongside your other electronics. Remove your liquids bag containing e-liquid and place it separately. This is all that is required.
Can you vape in airport departure lounges?
In most UK departure lounges, no. Vaping is treated the same as smoking and is restricted to designated areas only. These are usually located outside the terminal before you pass through security. Some airports have indoor smoking rooms but these are rare and inconsistent. Always check the specific airport's website before travelling if this is important to you.
