Heat Networks: Repairs and Maintenance

The question

To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the (a) total and (b) per dwelling building remediation costs associated with the proposed Heat Network Technical Assurance Scheme.

Answered by Miatta Fahnbulleh

The rules of the Heat Network Technical Assurance Scheme (HNTAS) are still under development, and it would be inappropriate to pre-emptively set out potential costs ahead of publishing our technical standards consultation and options assessment this summer.

To support the sector with remediation costs arising due to HNTAS, the Heat Networks Efficiency Scheme will deploy up to £75 million of capital grants and £2 million of revenue grants between 2023 and 2028.
