Last updated Updated May 2026· Reviewed against current airport security guidance
The UK is rolling out CT scanners airport-by-airport. As of 2025, a handful of airports allow up to 2 litres in the cabin; the biggest ones (Heathrow, Stansted, Manchester) still don't.
Rule basis: General airport security guidance — rules can vary between airports and change over time. Confirm with your departure airport before you fly.
What to do: Pack to 100ml per container in a single 1-litre clear bag unless you've confirmed a larger allowance at both your departure airports.
Liquid Limits is a travel planning tool, not an official aviation source. Always confirm with the airport before you travel.
London Gatwick, Edinburgh, Bristol, Aberdeen, Teesside, City of Derry, London City (some lanes).
London Heathrow, London Stansted, London Luton, Manchester, Birmingham (mostly), Glasgow, Belfast.
The UK DfT has previously reversed 2L allowances at upgraded airports with minimal notice. Treat 2L as a bonus, not a guarantee.
