The Regulations formally prescribed the Civil Aviation Authority (CAA) as the market surveillance authority for Commission Delegated Regulation (EU) 2019/945 concerning unmanned aircraft systems.

The Regulations created criminal offences for UAS operators and remote pilots breaching the UK Implementing Regulation for drone operations, set penalties, and amended related UK Acts concerning police powers and existing air navigation rules.

These Regulations establish criminal offences in the UK for UAS operators and remote pilots who fail to comply with specific requirements detailed in the Commission Implementing Regulation (EU) 2019/947 concerning the operation of unmanned aircraft systems (UAS).

The legislation, which comes into force in January 2026 across the whole of the UK, specifies the breaches that constitute offences, ranging from registration failures to competency issues across 'open', 'specific', and 'certified' flight categories, sets out associated summary conviction penalties, and makes consequential amendments to the Police Act 1997, the Air Navigation Order 2016, and the Air Traffic Management and Unmanned Aircraft Act 2021 to reflect these new criminal provisions.
