Personal Travel Agent Louise Patrick explains the new UK Airport Security Changes 2026 for Travellers
Airport security rules in the UK are changing in 2026, and for many travellers this will be the biggest shift in airport procedures in nearly two decades.
The long-standing 100ml liquid restriction is already being removed at some airports thanks to new CT scanning technology, making security queues faster and packing much easier. However, the transition is still ongoing across the UK, which means rules can vary depending on where you fly from.
As a personal travel consultant, Louise is already helping clients navigate these changes so their holidays begin smoothly from the moment they arrive at the airport.
Here is everything you need to know before you travel.
Heathrow Removes the 100ml Liquid Rule
At London Heathrow Airport, new next-generation scanners are now fully operational.
As of January 2026:
Liquids, gels and pastes can be carried in containers up to 2 litres in hand luggage (with some exceptions)
Laptops and tablets can usually remain inside your cabin bag during screening
Clear plastic liquid bags are no longer required
The new CT scanners create highly detailed 3D images of baggage contents, allowing security officers to detect prohibited items without passengers unpacking liquids or electronics.
For travellers, this means a quicker and far less stressful airport experience.
Which UK Airports Have Changed Their Security Rules?
Several UK airports have already upgraded their screening technology.
Airports where the 100ml limit has been lifted include:
Edinburgh Airport
Birmingham Airport
Bristol Airport
Other major airports, including London Gatwick Airport, are continuing to install scanners and may have a mix of old and new procedures depending on the security lane used.
Because of this phased rollout, travellers should always check their departure airport guidance before flying.
Important: Some Airport Rules Still Apply
Even with the new technology, certain security restrictions remain unchanged:
Metal or vacuum bottles must usually be empty during screening
Prohibited items such as sharp objects or flammable materials are still banned
Airports outside the UK often continue to enforce the traditional 100ml liquid rule
If you are travelling internationally or connecting through another airport, different rules may apply during your journey.
Why These Airport Security Changes Matter
The new security procedures are designed to improve the passenger experience significantly.
Benefits include:
Faster security queues with less unpacking
Reduced stress for families and frequent travellers
Easier packing with larger liquid containers allowed
Fewer single-use plastic bags
A smoother start to holidays and business trips
For longer trips such as cruises, multi-destination itineraries or family holidays, the flexibility is particularly helpful.
Travel Tips: How to Prepare for Airport Security in 2026
During the transition period across UK airports, preparation is key.
Check your airport before travel
Security rules depend on whether new scanners are installed and operational.
Pack cautiously if unsure
If you cannot confirm the rules:
Keep liquids in 100ml containers inside a clear bag as a precaution
Ensure electronics are easy to access if removal is required
Understand special allowances
Baby food, medical liquids and prescription medications may follow different guidelines.
Consider your return journey
Many overseas airports still apply older rules, so your return flight experience may differ from your departure.
