At SEN · the three rule systems
Security · Airline · Border
At London Southend, the liquid limit depends on your terminal, checkpoint or flight. UK rules vary by airport — some allow up to 2L, others enforce 100ml. Pack to 100ml unless the airport confirms otherwise.
Your airline's cabin-bag size and weight limits still apply on top of security rules.
Customs and import rules depend on where you land and what you carry — this airport page doesn't cover them.
Three separate rule systems · Any one can stop your item
Some liquids are fine through airport security but restricted by customs, biosecurity, alcohol duty, medicine rules or destination law.
Some prescription medicines, hormone gels, syrups and controlled drugs need documentation or prior approval before travel.
