The Nuclear Installations (Prescribed Conditions and Excepted Matter) Regulations 2025

Certain types of nuclear sites are subject to the nuclear third party liability (“NTPL”) regime established by the Nuclear Installations Act 1965 (“the Act”). In the event of a nuclear incident, the NTPL regime channels liability exclusively and strictly to the operator of the site responsible for the incident, however that liability is capped. The NTPL regime also requires operators of sites to have Secretary of State approved financial security arrangements in place to ensure they can meet any claims up to that cap. The Act implements the United Kingdom’s NTPL obligations under the 1960 Paris Convention on Third Party Liability in the Field of Nuclear Energy (the Paris Convention).
