## Summary

The Department for Work and Pensions commissioned independent validation and quality assurance of its Households Below Average Income (HBAI) statistics and associated datasets for specified published years. This is social research and statistical assurance work, intended to test the quality and reliability of the published figures and supporting data. The listed delivery locations span the United Kingdom and a range of overseas territories and locations. The requirement is focused on DWP’s HBAI statistical outputs rather than general research or broad data services.

The procurement is complete and awarded following an open procedure. The Institute for Fiscal Studies was selected, with an award date of 12 October 2026 and an awarded value of £326,445. The contract runs from 12 October 2026 to 11 October 2029. The tender’s estimated value was also £326,445. The submission deadline was 26 August 2026 at 5pm. Small and medium-sized enterprises and voluntary, community and social enterprises were identified as suitable. The published procurement information does not state a separate evaluation weighting or breakdown of award criteria.

For organisations competing when this specific DWP requirement next returns to market, the award indicates demand for independent scrutiny of official income statistics and their associated datasets. A credible supplier would need demonstrable expertise in statistical validation, data quality assurance and social research, with the capacity to examine published outputs and underlying data across specified years. The work spans a multi-year contract and has a broad stated delivery footprint, so bidders should be able to sustain a rigorous, reliable service over time and manage work connected with locations beyond the UK as required. The selected supplier was the Institute for Fiscal Studies, an SME, showing that this specialist requirement was delivered by a smaller organisation.
