Written Question
Solar Power: Finance
Tuesday 28th July 2026

Asked by: Lord Booth (Conservative - Life peer)

Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government whether ECO4 grants are still available to eligible individuals or bodies for solar panels and battery storage until December; and whether there is an obligation on energy companies to process new applications.

Answered by Baroness Curran - Parliamentary Under-Secretary of State (Department for Energy Security and Net Zero)

ECO4 is not a grant scheme. Obligated energy suppliers fund and deliver measures to eligible households, recovering costs through energy bills. Battery storage is not eligible under ECO4.

ECO4 has been extended to 31 December 2026 to give suppliers more time to meet their targets, complete outstanding obligations, and carry out remediation. Whilst new applications are allowed, some energy suppliers may slow delivery of measures including solar panels or reduce supply-chain contracting, which could limit support for some households. The extension gives more time for existing commitments but does not create new obligations or increase targets.
