Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential implications for the gas transmission network’s cyber security capabilities if it does not receive adequate funding under Ofgem’s RIIO-GT3 price control.

Funding for National Gas Transmission is set by Ofgem’s RIIO (Revenue = Incentives + Innovation + Outputs) framework for each five-year regulatory period. Both the current RIIO-2 framework (covering the 2021-2026 regulatory period) and the draft RIIO-3 framework (which will cover 2026-2030) include a Cyber Resilience UIOLI (‘Use it or lose it’) allowance, providing flexible funding capped at up to 20% of total expenditure for network companies to improve cyber resilience.

While arrangements for RIIO-3 are still being finalised, the framework is expected to include a re-opener enabling National Gas Transmission to request changes to cyber resilience funding during the 2026-2030 price control period.
