In the government’s Housing Delivery Test 2025, Milton Keynes built 142% of the homes it needed over three years: no consequence.
The council delivered at least 95% of the homes it needed.
Its adopted local plan is the Plan:MK, adopted March 2019 (7 years ago; plans are meant to be reviewed at least every five years).
A new plan, the Milton Keynes City Plan 2050, is at final consultation (Regulation 19).
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 4,720 outlines of an acre or more, 14 (0%) are mostly in Green Belt. 484 (10%) are partly in flood zone 3, the highest risk.

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
1,797 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.
