Liquid rules at every UK airport in 2026

There is no single UK liquid rule any more. It depends entirely on which airport you fly from — and the difference between two airports 40 miles apart can be the difference between keeping a full-size moisturiser and watching it go in the bin.

Why the rules split in two

The 100ml rule arrived in August 2006, after police uncovered a plot to assemble explosives on transatlantic flights from liquids carried in hand luggage. It was introduced as a temporary emergency measure. It lasted nearly twenty years.

The reason it lasted was technological. Old 2D X-ray machines could not reliably tell shampoo from something dangerous, so limiting the volume was the only safe answer.

CT scanners solved that. They build a detailed 3D image of a bag — the same principle as a hospital scanner — letting staff identify contents without opening anything. Once an airport completes installation and passes Department for Transport certification, it can lift the cap to 2 litres per container, with no limit on the number of containers.

The part most guides leave out

This rollout has been genuinely chaotic, and the history is why you should never assume.

The original deadline was 2022. It was missed. It moved to June 2024, then June 2025. In June 2024, six regional airports that had already scrapped the 100ml rule — Newcastle, Leeds Bradford, London City, Aberdeen, Southend and Teesside — were ordered to reinstate it within days. The DfT said it was to allow further improvements to the checkpoint systems, and stressed it was not a response to any specific threat. Reporting at the time indicated the new scanners were flagging harmless items such as sunscreen at a higher-than-expected rate, causing hand searches and long queues. The EU and wider Schengen area made a similar reversal from September 2024.

Heathrow lifted its limit in January 2026 after a scanner programme reported at around £1 billion. Gatwick, Edinburgh, Birmingham, Bristol and the two Belfast airports followed.

Every UK airport: the complete list

Checked on [INSERT DATE] against GOV.UK guidance and official airport security pages. Smaller airfields do not always publish individual guidance — assume 100ml unless the airport's own page states otherwise. Signage and security staff instructions on the day are the final authority.

The airports people ask about most

Manchester

The single most searched exception, and the answer is still no. Manchester enforces the 100ml per-container limit across all three terminals in 2026; its CT scanner programme has not yet passed the certification needed to lift the cap.

The improvement: you can leave liquids inside your cabin bag rather than displaying them in a clear pouch. So pack to 100ml, but expect a smoother belt. Because Manchester carries such a large share of UK holiday traffic, this one airport is why the old habit is still worth keeping nationally.

Heathrow

All terminals — T2, T3, T4 and T5 — allow containers up to 2 litres, with no clear bag and no need to remove liquids or electronics. A full-size sun cream, a 1-litre water bottle or a large bottle of shampoo are all fine departing Heathrow.

Stansted and Luton

Both still on 100ml. This catches out a lot of people flying budget routes, because these two are among the most common return airports for travellers who departed from a 2-litre airport.

London City

Currently 100ml — and a good illustration of why you should always check. London City scrapped the rule early, then had to reinstate it in June 2024 along with five other regional airports, and has not moved back since.

Bournemouth

Frequently listed incorrectly as a 2-litre airport. Bournemouth dropped the clear plastic bag requirement and now lets liquids and laptops stay in your bag — but the 100ml container limit still applies. The airport itself has warned passengers to check restrictions for their return journey.

The catch: your return flight

The rule that applies is the rule at the airport you are departing from, every time you pass through security.

Fly out of Heathrow with a 500ml moisturiser and it is fine. Fly home from Manchester, Stansted, Malaga or Dubai and the same bottle goes in the bin. Most airports outside the UK still run the traditional 100ml system, and the EU reverted to it in 2024.

Practical rule: if any leg of your trip departs from a 100ml airport, pack the whole trip to 100ml.

What counts as a liquid

Broader than most people expect. Government guidance includes:

• All drinks, including water
• Liquid and semi-liquid foods — soup, jam, honey, syrup, yoghurt, soft cheese, nut butter, sauces, hummus
• Cosmetics and toiletries — creams, lotions, oils, perfumes, mascara, lip gloss
• Sprays — shaving foam, hairspray, spray deodorant
• Pastes, including toothpaste
• Gels — hair gel, shower gel
• Contact lens solution and all aerosols

Two things catch people out constantly. The container size counts, not the contents — a 200ml bottle that is nearly empty will still be rejected at a 100ml airport, because security reads the label, not the fill level. And semi-liquid foods count — a jar of honey or a tub of hummus is treated exactly like shampoo.

Exceptions that apply even at 2-litre airports

• Vacuum flasks and insulated bottles must be emptied. The double-wall insulation blocks the scanner. This applies at Heathrow and Gatwick too.
• Duty-free liquids over 100ml bought outside the UK must stay sealed in a security tamper-evident bag with the receipt visible if you are connecting.
• Baby food, formula and prescription medication have long-standing exemptions above 100ml, but you may be asked to open, taste or provide proof.
• Airline cabin bag limits are a separate rule. Security may permit 2 litres; your airline's size and weight allowance is unaffected — and 2 litres of water weighs 2kg.

Your packing checklist

1. Check your departure airport's own security page the week you fly — not a news article, not this page.
2. Check your return airport too. This is the step almost everyone skips.
3. Default to 100ml if any leg is uncertain. Decanting takes five minutes and removes the problem entirely.
4. Keep a clear resealable bag in your case regardless. It weighs nothing and covers you at smaller airports.
5. Empty your flask before you leave home, not at the security bin.
6. Buy full-size liquids airside if you need them — anything bought past security is fine for that flight.

Allow time regardless

The new scanners were meant to speed queues up, and at fully upgraded airports they largely have. But 2026 is a peak-traffic summer, and mixed rules across airports mean staff are still spending time explaining the change at the belt. Standard guidance holds: two hours before short-haul, three before long-haul.
