Housing Need and Demand Assessment (HNDA) A Managers Guide (2026)

Comparability with previous HNDAs

For unitary local authorities, the outputs of the previous HNDAs will be comparable to the current HNDA. Where groups of LAs work together as a City Region to produce an HNDA, these will be comparable with previous SDPA HNDAs but also slightly different where an LA has decided not to part of a regional grouping.

Those authorities who are part way through their HNDA at the time of this refresh can continue to use the previous version of the Tool (v4.0) and guidance should they wish to or they can choose to use the refreshed version of the Tool (v5.0) and guidance. Authorities who are in this position may wish to contact the Centre for Housing Market Analysis (CHMA) for advice.
