• The CAA has been responsible for aviation security regulatory activity and compliance monitoring since 1 April 2014, when these functions transferred from the Department for Transport (DfT). The respective present roles of the DfT and CAA in the aviation security field are documented in a Memorandum of Understanding and its annexed Statement of Responsibilities.

    This expansion of our role was anticipated in the better regulation for aviation security consultation in 2011, and the relevant legal powers were set out in the Aviation Act 2012. New aviation security vetting responsibilities also formed part of the transfer package.

    Alongside the transfer of these functions has come a requirement for industry, rather than the tax payer, to meet the cost of delivering them. This is in line with the 'user pays' principle which already applies generally across aviation regulation.

    While the Government leads on international aviation security matters and UK aviation security policy (including the setting of security standards), the CAA regulates security arrangements at UK airports and for air carriers, cargo and in-flight suppliers to ensure that the relevant entities comply with UK and international security requirements. An overview of our responsibilities is available.

    Restricted items at airports

    Certain items are prohibited by law from being taken through airport security. Whether an item that is not prohibited is allowed through security is ultimately at the discretion of the airport, which may not allow any item it considers dangerous. The Department for Transport has a guide to hand baggage restrictions at UK airports, but you should check with the airport you are travelling from before departure if you have any concerns. We have produced additional detailed guidance on certain items that can cause issues at airport security.
