The UK is a party to the international nuclear Liabilities regime established by the 1960 Paris Convention and its subsequent Amendment agreements. These international obligations are implemented by the Nuclear Installations Act 1965 (NuIA 1965), as amended by various primary and secondary legislation to reflect Convention amendments and UK policy choices within the permitted parameters.

The most recent of these is the Energy Act 2023 (EnA 2023), which amends the NuIA 1965 to implement the Convention on Supplementary Compensation (CSC). EnA 2023 also gives the Secretary of State power to make regulations to implement the CSC or otherwise for the purposes of dealing with matters related to, or arising out of, the CSC.

This Practice Note summarises the evolution and current position of UK nuclear liability law and discusses the changes brought about by the EnA 2023 to the NuIA 1965.
