Milton Keynes covers 16 postcode districts in Milton Keynes, all listed below. Planning applications here are decided mostly by the Milton Keynes planning authority, with Buckinghamshire, Central Bedfordshire and West Northamptonshire covering the rest. Below: what homes sold for, which planning controls apply, and what that means before you sell or develop a plot in Milton Keynes.
Residential sales recorded by HM Land Registry between 2024-08 and 2026-07 across all 16 of Milton Keynes's postcode districts. This is market context for the town, not a land valuation: what a plot is worth depends on what can be built on it, which these figures do not show.

6 separate directions recorded, each removing particular permitted development rights within a defined area. The largest named one is the Article 4 Direction relating to Houses in Multiple Occupation (HIMO) - Non immediate direction.
No postcodes in Milton Keynes's 16 districts fall inside: National Landscape (AONB), National Park.
Flood zones, tree preservation orders, local plan allocations, settlement boundaries and non-designated heritage are not included here and are checked in a full assessment.
2% of postcodes in Milton Keynes are inside the Green Belt, so Milton Keynes has land both inside and outside it. The Green Belt postcodes sit mostly in MK17. Which side of the boundary a plot sits on determines whether the Green Belt tests apply to it at all.
91% of postcodes are covered by an Article 4 direction, which removes specific permitted development rights in that area, so changes that are automatic elsewhere need a planning application there.
These are town-level facts. The free assessment checks your actual boundary against the same registers and the local plan and tells you plainly what they mean for your plot.
Milton Keynes's 16 districts are split between planning authorities: Milton Keynes (91% of sampled postcodes), Buckinghamshire (4%), Central Bedfordshire (3%), West Northamptonshire (2%).
Draw your boundary, tell us what you own, and an architect checks it against these registers and the local plan. Free, no obligation, and you get a straight written answer.
It depends on where the plot sits, not on the town average. Across Milton Keynes, 2% of postcodes are in the Green Belt and 5% in a conservation area. Green Belt land is concentrated in MK17; on Green Belt or National Landscape plots a new home is the exception and needs a specific case, and a replacement dwelling, a conversion or a modest extension is usually the realistic route. Outside those designations the questions that decide it are whether the plot is inside or adjoining the settlement boundary in the local plan, whether it has its own road access, and what is next to it.
Often, yes. 91% of postcodes in Milton Keynes are under an Article 4 direction (6 separate directions), which withdraws particular permitted development rights, so an outbuilding, extension or change of use that is automatic elsewhere needs an application there. Outside those areas, permitted development applies to houses and their gardens but not to agricultural land or paddocks, where a new building or a new use normally needs permission or prior approval.
Developers look at three things before they talk about price: whether the plot is outside the Green Belt and any National Landscape, whether it sits inside or beside the settlement boundary, and what finished homes sell for. In Milton Keynes the median sale is £353,400, from £246,250 in MK9 to £465,000 in MK17, and 24% of 2023–2024 sales were new-build homes, so builders are active here. A single plot usually goes to a local builder or a self-builder; a site for five or more homes attracts regional housebuilders, normally through an option or a conditional contract rather than an outright purchase, so the price you see quoted is not the price you receive.
There is no town figure for land, because a plot's value comes from what can be built on it, not from where it is. As a guide, a serviced plot with consent for one house commonly sells for around a third of the finished house value, which in Milton Keynes would be measured against a £353,400 median sale. The same plot without consent, or inside the Green Belt, is worth a small fraction of that, and a paddock with no realistic route to consent is worth agricultural or amenity value only. The free check tells you which of those your plot is before you talk to anyone about a price.
