The Milton Keynes local plan
The development plan is Plan:MK (adopted March 2019, covering 2016 to 2031) together with the Site Allocations Plan (2018), the council's own Minerals Local Plan (2017) and Waste Development Plan Document (2008), and 23 made neighbourhood plans. Milton Keynes is a unitary authority and its own minerals and waste planning authority.
The MK City Plan 2050 was submitted for examination after Regulation 19 consultation closed in February 2026, and it plans for around 50,000 new homes to 2050. Because it is at examination it is a material consideration carrying real weight, but Plan:MK remains the adopted plan.
What tends to shape decisions here: Milton Keynes is one of the strongest housing delivery authorities in England, with a Housing Delivery Test result of 147 per cent and a five year supply the council puts above six years, so the tilted balance is not engaged on delivery grounds and schemes are judged on the plan's own terms. The distinctive constraints are the grid road and linear park structure that shapes layout and access, the strategic urban extensions coming forward around the city edge, and conservation areas in the older towns of Newport Pagnell, Olney, Stony Stratford and Woburn Sands rather than in the new city itself.
