Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what was the budget for a) security and b) cyber security in the National Gas business plan each year for the past five years.

Funding for National Gas Transmission is set by Ofgem’s RIIO (Revenue = Incentives + Innovation + Outputs) framework for each five-year regulatory period.

For security reasons, Ofgem does not publish the specific allowances awarded for physical or cyber security. These investments are designed to strengthen resilience, often for Critical National Infrastructure, and disclosure could increase risks to individual companies and the wider energy sector.
