London - Europe’s busiest airport, Heathrow, has scrapped the rule of carrying liquid containers of up to 100ml only in passenger luggage.
Passengers can now leave liquids in containers up to two litres in their bags while going through security, after it finally completed the rollout of new high-tech CT scanners.
Electronics such as laptops can also be left in luggage, while clear plastic bags for liquids no longer have to be used.
Heathrow has become the biggest airport in the world to have the new equipment fully rolled out across all its terminals.
Gatwick, Edinburgh and Birmingham airports in the UK have already increased to a two-litre limit, BBC News reported.
The airport rule, introduced in August 2006 following concerns over liquid explosives, has come to an end at the London airport following the completion of a one-billion-pound technology upgrade set to deliver the fastest, smoothest security experience to date.
Until Friday 23 January 2026, a majority of jetsetters were forced to sort their liquids into clear plastic bags on approach to Heathrow’s security scanners and remove electronic equipment from hand luggage. However, both may now remain in luggage unless flagged by security staff.
The change comes as the rollout of next-generation CT security scanners has finished, promising faster queues, less stress and a smoother start to journeys through the airport, which handled 84.5 million passengers in 2025.
The rule change only applies to flights leaving Heathrow, and passengers must check restrictions on luggage at the airports they are returning from before boarding flights to the UK, officials said.
