Annex B: Resources


The table below sets out our expected funding for 2024/25 based on the settlement as agreed through Spending Review 2021 (SR21), adjusted for changes that have occurred since then. The table sets out our anticipated operating budgets for 2024/25 – the last year of the SR21 period. The table aggregates the constituent elements of our overall funding into a ‘Total Departmental Expenditure Limit’ (TDEL) which forms the total budget for the year. TDEL is made up of two spending control totals set by HM Treasury relating to net resource and net capital expenditure.

2024/25 expected funding£m
Core and other income243.5
Ambitious Radical Inclusive Economic Statistics Programme (ARIES)23.6
Future Population Migration Statistics Programme (FPMS)54.9
Integrated Data Service Programme (IDP)55.3

Totals may not sum due to rounding.


All funding from HM Treasury is subject to Parliament’s approval of the 2024/25 Main Estimate. That approval is not expected until June 2024 and therefore the details provided in the table above may be subject to change.

The ONS expects to generate around £26-30m of external income during 2024/25 based on current assumptions and following the trend of prior years. This income will be used to offset the marginal costs of generating the income, including overheads.

At the Autumn Statement in November 2022, HM Treasury announced an Efficiency and Savings Review whereby all government departments were asked to set out how they aimed to live within their current means considering wider fiscal constraints. The ONS has contributed to this exercise – submitting a series of proposals which set out how we plan to address further anticipated cost pressures (including additional inflationary impacts) for 2024/25. These proposals make up our ONS Efficiencies and Savings Plan (ESP) as explained in earlier sections of this Strategic Business Plan.
