Question to the HM Treasury:

To ask the Chancellor of the Exchequer, with reference to the Secretary of State for Transport's Oral Statement of 24 March 2025 on Road Maintenance, whether she has made an estimate of the Barnett consequential funding for Wales of the additional £500 million highway maintenance funding.

At Phase 1 of the 2025 Spending Review, an additional £500 million was allocated to the Department for Transport to fund local highways maintenance in 2025-26. The Barnett formula was applied in the usual way to changes in the Department for Transport’s Delegated Expenditure Limit (DEL) budget.

At Spending Reviews, the Barnett formula is applied to changes to each UK Government department’s overall DEL budget, rather than to individual programmes.

The Welsh Government’s Spending Review settlement for 2025-26 is the largest in real terms of any Welsh Government settlement since devolution.  The Welsh Government is receiving at least 20% more funding per person than equivalent UK Government spending in England. That translates into over £4 billion more in 2025-26 and includes £1.7 billion through the operation of the Barnett formula.

The Block Grant Transparency publication breaks down all changes in the devolved governments’ block grant funding from the 2015 Spending Review up to and including Main Estimates 2023-24. The most recent report was published in July 2023. An update to Block Grant Transparency to include Autumn Budget 2024 changes will be published in due course:
