Question to the HM Treasury:

To ask the Chancellor of the Exchequer, to publish a breakdown of the spending decisions in England that generated the £508 million of Barnett consequentials for Wales at the 2025 Autumn Budget.

As a result of decisions at Budget 2025, the Welsh Government will receive an additional £320 million RDEL and £185m CDEL through the operation of the Barnett formula on top of the record settlement provided at Spending Review 2025. This means that the Welsh Government’s settlement continues to grow in real terms between 2024-25 and 2028-29.

The Welsh Government are free to allocate Barnett consequentials as they see fit across their devolved priorities

Where policy changes will take effect in years beyond the existing Spending Review 2025 period, the Barnett formula will apply when departmental budgets change at the next Spending Review.
