The Department for Energy Security and Net Zero (DESNZ) has launched a consultation on a proposed Tier 1 Cyber Assessment Framework (CAF) profile and related guidance for Large Load Controllers, seeking views on cyber security requirements for organisations that remotely control 300MW or more of electrical load through energy smart appliances and that are expected to be brought within the scope of the Network and Information Systems (NIS) Regulations 2018, SI 2018/506, as a new essential service. DESNZ, in collaboration with Ofgem and the National Cyber Security Centre, has developed the proposed framework to support cyber resilience in the load control sector. The consultation seeks views on the proposed CAF profile, a sector-specific CAF overlay, scoping guidance and compliance arrangements, which are intended to address cyber risks associated with organisations controlling large volumes of electricity demand through technologies such as electric vehicle charge points, heat pumps and battery storage systems. The consultation closes on 1 September 2026.
