Our original delegated budget, set at the 2021 Spending Review, was £4,316,000 for 2023-24. This was uplifted by £250,000 in our annual delegation letter to £4,566,000 to provide additional resources for a new supply side analysis unit. The delegation letter also committed to funding the cost of transferring the OBR’s IT function to HM Treasury’s TrIS network. Our budget was increased by £1,000,000 in supplementary estimates to cover the new analytical unit, our IT migration costs, and a number of one-off in-year pay-related pressures, including the civil service-wide in-year pay uplift of £1,500. The statement of comprehensive net expenditure in this year’s accounts puts our total spending for the year at £5,442,000.
