Annex A: Resources


The table below sets out our funding settlement as agreed through Spending Review 2021 (SR21) as adjusted for changes that have occurred since then. The table sets out our anticipated operating budgets for the remainder 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 period. TDEL is made up of two spending control totals set by HM Treasury relating to net resource and net capital expenditure.

Future Population Migration Statistics funding has been approved for six months of 23/24 at £12.4m. The current estimates of full funding required for the programme in 23/24 and 24/25 are £28.4m and £35m respectively.

We estimate that we will generate around £26-30m of external income per annum through the SR period based on current assumptions. This income will be used to offset both the marginal costs of generating the income and to provide a contribution to the wider operational costs of the organisation.

At the Autumn Statement November 2022 HM Treasury announced an Efficiency Savings Review whereby all government departments were asked to set out how they aimed to live within their current means in light of wider fiscal constraints. We have 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 financial years 2023/24 and 2024/25.
