You may have heard that UK airports are planning to get rid of the 100ml or under liquids rule in the UK. However, there is still a lot of confusion around whether this rule is still in place. So we have put together this guide to let you know all about the UK Airports New 100ml Liquids Rule. Here’s what you Need to know.

Current Status of the 100ml Rule

Despite advancements in security technology, the 100ml liquid restriction is still enforced across the UK. The Department for Transport (DfT) had initially planned to lift this restriction by June 2024. However, due to delays in the installation of new 3D computed tomography (CT) scanners at major airports like Heathrow, Gatwick, and Manchester, the deadline was extended to June 2025. These delays were primarily caused by technical issues and supply chain constraints (The Guardian, 2024).

Why Do We Have the 100ml Liquid Rule at Airports?

Airports worldwide limit liquids, aerosols and gels in carry-on luggage to 100ml containers, up to 1000ml in total. Place these in a clear, resealable plastic bag (about 20cm x 20cm) and remove them from your luggage for security scanning.

In 2006, authorities foiled a plot when terrorists attempted to take 500ml bottles of hydrogen peroxide onto at least 10 planes to make a bomb. Ever since, passengers have been allowed to carry only 100ml of liquid onto planes, and this rule has been adopted worldwide.[2]

Airports with Updated Security Measures

While the 100ml rule remains nationwide, several UK airports have begun implementing advanced CT scanners that allow passengers to keep liquids and electronics in their hand luggage during security screening. These airports include:

• Birmingham
• Bristol
• Edinburgh
• Gatwick
• Leeds Bradford
• Luton
• Newcastle
• Southend
• Teesside

At these airports, passengers may not need to remove laptops or liquids under 100ml from their bags during screening. However, the 100ml limit still applies, and passengers should check with their specific airport for the most current procedures.

How do the New CT Airport Security Scanners Work?

The new CT scanners provide a 3D image of the contents of a bag, allowing security personnel to detect potential threats without the need to unpack items. This technology enables passengers to leave liquids and electronics in their hand luggage, streamlining the security process. However, these scanners are not yet universally available, and the 100ml liquid restriction remains in place until all airports are equipped with the new technology (CN Traveller, 2024).

Does the 100ml Liquids rule still exist in airports?

Until the new scanners are fully implemented across all UK airports, passengers should continue to adhere to the 100ml liquid rule. This includes placing all liquids, aerosols, and gels in containers of 100ml or less, fitting them into a single, transparent, resealable plastic bag with a total capacity not exceeding one litre. Items such as beverages, toiletries, and cosmetics are subject to this restriction.

It’s important to note that while some airports have introduced new security measures, the overarching liquid restrictions remain unchanged. Passengers should stay informed about the specific rules at their departure airport and be prepared for potential changes as the rollout of new security technologies continues.

Make Sure You Have Travel Insurance

This innovative approach to airport security aims to keep passengers safe and keep security queues moving. However, it’s always wise to protect yourself against potential disruptions. Investing in robust travel insurance can help cover you financially, ensuring that your journey is as smooth and stress-free as possible.

Remember, travel insurance is not just an added expense. It’s a safeguard against the unexpected, providing coverage for various issues that can arise before, during, or after your trip. Consider purchasing a policy that suits your needs, whether it’s for a single trip or annual coverage for frequent flyers. With travel insurance, you can focus on enjoying your journey, knowing that you’re protected.
