In the government’s Housing Delivery Test 2025, West Northamptonshire built 104% of the homes it needed over three years: no consequence.
The council delivered at least 95% of the homes it needed.
A new plan, the West Northamptonshire Local Plan 2043, is at early consultation (Regulation 18).
From MHCLG’s Housing Delivery Test and the Planning Data platform’s local plan records, which some councils haven’t kept up to date. Whether the tilted balance applies to a scheme also depends on the council’s five-year land supply and the site itself: get planning advice.
Planning constraints
None of West Northamptonshire’s larger outlines are mostly in Green Belt. 1,509 (11%) are partly in flood zone 3, the highest risk.

Counts are of HM Land Registry INSPIRE title outlines (one title can have several outlines, and an outline isn’t always one field), counted under the council HM Land Registry files them with. Substations are from OpenStreetMap. None of this says whether land is for sale or could get planning permission.
