Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether the underspend from the Boiler Upgrade Scheme for the year ending 31 March 2023 will be carried over into the following year’s budget.

The Boiler Upgrade Scheme (BUS) budget is £450 million, split equally over three financial years (2022-2025). Budget remains available for use in year 1 of the scheme, however we do not expect this to be fully utilised based on latest forecasts. We have explored options to carry over unused budget from year 1 of the scheme, but due to the accounting rules for capital spending schemes we do not expect this to be possible.
