Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 4 December 2025 to Question 95968, for what reason there is a difference between the estimates of the fiscal cost of freezing rail fares (a) as set out in that Answer and (b) the figures published in the Office for Budget Responsibility’s Economic and Fiscal Outlook, November 2025.

The difference is due to a difference in rounding. The estimates provided in the Department’s previous response were sourced from the published Budget document, where numbers are rounded to the nearest £5m. The OBR choose to round figures to the nearest £1m in their own publications, including their Economic and Fiscal Outlook published in November 2025.
