The Office of Gas and Electricity Markets (Ofgem) regulates and assesses the National Energy System Operator’s (NESO’s) performance against its regulatory Business Plan, and compliance with its other statutory and licence obligations. Ofgem’s most recent assessment, published on 2 September 2026, found that overall, NESO met expectations.
