PARLIAMENTARY WRITTEN QUESTION
(15 July 2026)

The UK uses diverse gas supply sources to meet winter demand, including domestic UK Continental Shelf production, pipeline and interconnector imports, and Europe’s second largest LNG import infrastructure.

Gas storage, filled from these sources, provides system flexibility to respond to short-term changes in supply and demand. In winter 2025/26, gas storage supplied 5% of total GB gas use and we expect it to contribute a similar amount this winter.

As set out in our interim response to the Gas System in Transition: Security of Supply consultation, we recognise that gas infrastructure needs may change through the energy transition. We will further assess whether additional infrastructure, including strategic gas storage, is required, and will publish a full response in due course.
