Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what levels of finance and support are required through schemes such as the Heat Network Efficiency Scheme to bring legacy networks up to the Heat Network Technical Assurance Scheme standards.

The Heat Network Efficiency Scheme (HNES), which provides grants to heat networks to carry out performance and efficiency improvement works, has the potential to provide some funding to networks for works that will bring them up to HNTAS standards.

We are currently consulting on the implementation of HNTAS, and are actively encouraging the sector to provide cost data through the consultation, so we can strengthen our evidence base on financial support that may be required and ensure the final policy is proportionate and deliverable.
