Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate his Department has made of the level of underspend, or projected underspend, in the first year of the Warm Homes Local Grant and Warm Homes Social Fund; how many local authorities have submitted expenditure data to date; and whether the Department has modelled the full-year underspend based on these partial returns.

The Warm Homes: Local Grant (WH:LG) and the Warm Homes: Social Housing Fund (WH:SHF) schemes began delivery in April 2025.

Both schemes were oversubscribed demonstrating the high ambition of local authorities and social housing providers. We continue to see strong demand in both schemes.

To maximise delivery, where potential underspend has been identified it has been reallocated to high performing projects to ensure that grant funding is used by the end of the financial year.

Across both schemes, the final in-year spend can only be confirmed following robust financial management assessments. Financial reporting for the schemes will be available as part of DESNZ’s published annual accounts.
