In the government’s Housing Delivery Test 2025, Sevenoaks built 25% of the homes it needed over three years: presumption in favour.
The council delivered under 75% of the homes it needed, so national policy's presumption in favour of sustainable development (the "tilted balance") applies to housing applications: permission should be granted unless the harm would significantly and demonstrably outweigh the benefits, or protective policies such as Green Belt, National Landscapes or flood risk give a clear reason to refuse.
Its adopted local plan is the Sevenoaks Core Strategy, adopted February 2011 (15 years ago; plans are meant to be reviewed at least every five years).
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
Of the 6,456 outlines of an acre or more, 5,838 (90%) are mostly in Green Belt. 481 (7%) are partly in flood zone 3, the highest risk.

Farmland quality
8% of the graded farmland outlines of an acre or more are grade 1 or 2, the best and most versatile land.

- Grade 34,245
- Grade 4816
- Non-agricultural409

Natural England’s provisional grades at the centre of each outline. A broad-scale map, so a field survey is needed for any one site.
Electricity network
1,121 outlines of an acre or more are within 1 km of a primary or grid substation.
The best 2 km square for a data centre scores 57 out of 100. Data centre site search →

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.
