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 his policies of the research paper by ADE entitled Electricity System Benefits of Heat Networks, published on 11 January 2025.

The Warm Homes Plan sets our strategy for upgrading buildings, including. the case for heat networks to decarbonise heat whilst reducing the cost of upgrading the grid. We estimate that heat network deployment will save £5-7 billion in avoided distribution network costs, even before flexibility is accounted for. ADE’s research adds to our understanding in this area.

Our Heat Network Zoning policy will ensure that heat networks are built where they are the lowest-cost low carbon option, whilst Regional Energy Strategic Plans will ensure a more strategic, joined-up approach to electrification at a distribution level.
