UK carry-on rules (CAA) — what you can and can't bring

Authority: UK CAA

The UK Civil Aviation Authority (CAA) sets carry-on security rules for all UK departures. The 100 ml liquid rule applies at every UK airport unless that airport has rolled out the new CT scanners (some have, some are still phasing in — confirm with your departure airport before you pack). Lithium battery rules mirror EU/ICAO. Bringing meat, dairy or plants from outside the UK has been restricted since Brexit.
