The UK Department for Transport has published formal guidance listing liquid explosive detection systems that it has approved for use in aviation security.
The document, titled "Guidance: Liquid explosive detection systems (LEDS) for aviation security", was published on 30 September 2026. The guidance identifies the LEDS that the Department for Transport has approved for deployment in aviation security settings.
The publication is presented as an official statement of the systems approved by the Department for Transport for use in aviation security. It is intended as a reference for parties with responsibility for screening at airports, and for supply chains and regulators engaged with aviation security equipment.
The guidance represents the department's formal position on which liquid explosive detection systems meet its approval criteria. It signals the completion of whatever assessment process the department uses to determine suitability for use in the UK aviation context.
What the guidance contains
The guidance is described by the Department for Transport under the title cited above and dated 30 September 2026. It sets out the list of LEDS that the department recognises as approved for aviation security roles.
The document therefore functions as a consolidated list for operational and procurement purposes. Operators and authorities can refer to it to confirm whether a given LEDS appears on the department's approved list.
Why the list matters
An official list of approved systems provides clarity for those responsible for screening at airports and for organisations that procure or maintain detection equipment. By publishing the guidance, the department has created a single point of reference for approved LEDS in the UK aviation security environment.
The guidance should be used alongside relevant local and national regulatory responsibilities. It is an instrument that informs which systems the Department for Transport accepts as approved for the stated purpose.
The Department for Transport's publication on 30 September 2026 makes clear which LEDS the department approves for use in aviation security. Those engaged in aviation screening, procurement and compliance are likely to consult the guidance when assessing equipment choices and verifying approvals.
The document is accessible under the Department for Transport’s publications and guidance listings. It is the authoritative departmental statement on the approval status of liquid explosive detection systems for aviation security as of the date shown.
