Question to the HM Treasury:

To ask the Chancellor of the Exchequer, with reference to the Written Statement of 16 April 2026 on Carbon Price Support, HCWS1519, what estimate her Department has made of the cost to tax revenues of abolishing Carbon Price Support in each financial year for which estimates are available; and what steps her Department is taking to fund this policy change.

As the grid continues to decarbonise, the Carbon Price Support (CPS) tax base will become smaller and CPS revenue is forecast to significantly decline.

Final costings will be confirmed at a fiscal event in the usual way. The Chancellor will set out details on how this, and any other decisions, are funded such that the fiscal rules are met at the Budget in the usual way.
