Heathrow security, baggage and liquids

What can I take through security?
All passengers must pass through Heathrow security control after check-in and before entering the departure lounge. Read our Heathrow security guide.
Additional security checks
For the benefit of all passengers' security, passengers may be required to be screened using security (body) scanning equipment.
The UK Government requires a “no scan, no fly” policy to be enforced, meaning that failure to comply if selected for a scan will result in refusal of entry.
Further information on the use of security scanners can be found on our FAQs page or by visiting the Department for Transport website.

Security updates
Religious and cultural headwear
New regulations issued by the Department for Transport now make it possible to security screen religious and cultural headwear by alternative means. If you’re selected for a search using our normal processes, you can opt for any headgear worn for religious or cultural reasons to be screened by the use of security technology as an alternative to being hand searched.

Travel to the USA
Passengers travelling to the United States should expect their airline to carry out additional security checks prior to boarding. To support this important process and keep delays to a minimum, we would advise passengers to check the relevant airline website or call the airline for specific advice before travelling to the airport, arrive promptly at check-in, and limit the amount of baggage being taken on board the aircraft. If in any doubt, please contact the relevant airline for further information.
