Government Response: ONR-DNSR merger confirmed

The Government will consolidate the nuclear regulatory landscape by merging ONR and DNSR, directly following the Taskforce recommendation. Initial changes will be implemented by Autumn 2026 with full merger completed by the end of 2028. The Government will also strengthen collaboration between the Environment Agency and ONR. This is a significant structural reform that addresses the fragmentation the Taskforce identified, though the full merger timeline extends beyond the original March 2026 target.
