Smoking and vaping at Heathrow

Find the smoking area locations using our interactive maps

Heathrow is a smoke‑free airport, in line with UK law. You cannot smoke or vape inside any terminal. 
 

Smoking outside

You can smoke or vape in marked areas outside the terminal. After security, smoking and vaping are not allowed anywhere.

If you carry an e‑cigarette, check with your airline first, as rules may vary by airline.

 

Connecting passengers and smoking

If you have a connecting flight, you cannot smoke or vape during your transfer. If you want to smoke, you need to go through passport control to leave the terminal building and use the outdoor smoking areas. You will then need to go through security again to return to the departure lounge. For more information on leaving the airport during the connections process, visit our connections page.
