English Indices of Deprivation - 2028 Refresh, Methods Review & Data Feasiblity

This Pre-Tender Market Engagement (PTME) seeks to inform a potential procurement for Suppliers to deliver specific tranches of work relating to the English Indices of Deprivation.
• Tranche 1 (T1): Direct refresh/update of the English Indices of Deprivation 2025 release (IoD25) for delivery in 2028.
• Tranche 2 (T2): Review of the Indices conceptual framework, its definitions, domain weights, balance between economic and non-economic measures and broader policy alignment.
• Tranche 3 (T3): Feasibility study on the challenges and opportunities in acquiring or producing data on wealth and assets.
All tranches will run concurrently. T1 is independent; Suppliers delivering T1 cannot undertake T2 or T3. T2 and T3 may be delivered by the same or different Suppliers.
PTME objectives:
• define the requirement in clear terms;
• assess the feasibility of the proposed requirement;
• identify optimal delivery approach;
• test market capacity to deliver, and identify potential risks involved;
• enable early supplier engagement and queries;
