Travelers flying in and out of the UK are experiencing a major change in airport security regulations in 2025. The long-standing 100ml liquid restriction, which required passengers to carry liquids in small containers and transparent plastic bags, has been scrapped in several airports. This move comes after the rollout of new security technology, making air travel more convenient without compromising safety. For millions of passengers, this change marks the end of one of the biggest inconveniences of modern air travel.
What Was the 100ml Liquid Rule?
The 100ml liquid rule was introduced in 2006 after a foiled terrorist plot involving liquid explosives. It required passengers to:
-
Carry liquids, gels, and aerosols in containers no larger than 100ml.
-
Pack them in a clear resealable plastic bag.
-
Limit the bag to one per passenger and present it separately at security checks.
Although effective for nearly two decades, the rule often frustrated travelers, leading to discarded toiletries and longer queues at security checkpoints.
Why Has the Rule Been Scrapped in 2025?
The key reason behind scrapping the rule is the adoption of next-generation CT (Computed Tomography) security scanners across many UK airports. These scanners create detailed 3D images of luggage contents, allowing security staff to detect dangerous substances without requiring passengers to separate or limit liquids.
This technology also enhances accuracy, reduces manual bag checks, and speeds up the security process. By replacing outdated scanning systems, airports are able to maintain strong security while improving passenger convenience.
Which Airports Have Removed the 100ml Limit?
As of 2025, several major UK airports have officially scrapped the 100ml liquid restriction. These include:
-
London City Airport
-
Teesside International Airport
-
Birmingham Airport
-
Manchester Airport
-
London Heathrow (selected terminals by mid-2025)
-
Edinburgh and Glasgow Airports (phased rollouts)
Other airports are in the process of upgrading their systems, with full nationwide implementation expected by the end of 2025.
What Are the New Liquid Rules?
Although the 100ml limit has been lifted, passengers must still follow certain guidelines:
-
Liquids up to 2 liters can now be carried in hand luggage at airports with upgraded scanners.
-
Containers no longer need to be placed in clear plastic bags.
-
Security staff may still request inspection of suspicious items.
-
Rules may differ at connecting airports overseas, so travelers should check local regulations when flying internationally.
These new rules make packing easier but still balance security with convenience.
Impact on Travelers
For passengers, the end of the 100ml rule is a significant relief. Benefits include:
-
No more restrictions on toiletries: Full-sized shampoo bottles, cosmetics, and personal care items can now be packed in hand luggage.
-
Faster security checks: Passengers spend less time unpacking and repacking items at checkpoints.
-
Reduced waste: Travelers no longer need to throw away items exceeding 100ml.
-
Smoother family travel: Parents carrying milk, formula, or medicine find the process far more convenient.
The changes are particularly beneficial for business travelers and frequent flyers, who often rely on hand luggage for short trips.
Why This Matters for UK Aviation
The scrapping of the 100ml rule is part of a larger modernization effort in UK aviation. By adopting cutting-edge CT scanner technology, the UK is positioning itself as a leader in aviation security innovation. This move also improves the passenger experience, making UK airports more competitive globally.
For airlines, faster security checks mean fewer delays, shorter queues, and smoother boarding processes. For passengers, it enhances convenience and reduces one of the most disliked aspects of travel.
Key Takeaways
The UK Airport 100ml Liquids Rule Scrapped in 2025 represents a milestone in aviation security and passenger convenience. With new CT scanners ensuring safety, passengers can now carry larger liquid containers in their hand luggage at upgraded airports.
While not all airports have adopted the change yet, the trend is clear: by the end of 2025, travelers across the UK can expect more freedom, less hassle, and quicker journeys through security.
