The UK Department for Transport published new guidance on 12 October 2026 setting out approved equipment for screening small volumes of liquids as part of aviation security measures.
The document, titled Guidance: Screening liquids less than 100ml: equipment, lists liquid explosive detection systems that the Department has approved for the specific purpose of screening volumes below 100 millilitres. The guidance is aimed at identifying systems judged suitable by the Department for Transport for this narrow technical role.
Liquid explosive detection systems, or LEDS, are referenced in the guidance as the category of kit under consideration; the published list identifies the devices that meet the Department's approval for screening small liquid samples in the aviation environment. The Department's publication confirms the systems are intended to support security screening where small-volume liquid assessment is required.
What the guidance covers
The guidance provides a consolidated reference for the aviation sector of the equipment that the Department for Transport has approved to screen liquids smaller than 100ml. It does not, within the material supplied here, specify operational procedures, procurement instructions or a wider regulatory change, but it establishes which systems have been assessed and accepted at the equipment level for that screening task.
The publication therefore serves as a technical inventory rather than a policy statement on how screening should be conducted across airports, and it makes clear that the Department has completed a process of evaluation and approval for specific LEDS intended for the small-volume context.
Industry implications
It is reasonable to infer that manufacturers, airport operators and security suppliers will consult the Department's list when considering equipment suited to screening small quantities of liquid, since an approved list gives a clear signal about which systems have met the Department's assessment. That inference follows from the guidance's function as an approval record for LEDS used in this precise screening niche.
Operators and suppliers will likely treat the list as a technical reference when planning capability or maintenance related to small-volume liquid screening; the guidance provides a single source confirming which devices have received departmental approval for the stated purpose. Any decisions about deployment, procurement or integration with existing checkpoints will, however, remain a matter for the operators and their own regulatory and contractual arrangements.
The Department's publication is dated 12 October 2026 and appears on its website, where the listed LEDS and the scope of the approval are set out. Readers seeking the full details of the approved systems and the technical scope of their approval should consult that published guidance for the complete list and any accompanying notes.
The immediate effect of the guidance is to create a recognised reference point for a narrowly defined screening capability within aviation security. How individual airports and security providers respond will depend on their operational needs and existing equipment inventories, and any subsequent communications or industry notices that further explain the Department's assessment criteria or the practical implications of the approvals.
