National Gas: Security

Asked by Ben Obese-JectyConservativeDepartment for Energy Security and Net ZeroTabled Answered 5 December 2025UIN 94921

The question

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.

Answered by Michael Shanks

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.
