The August 2026 NPPF – What Has Changed ?

The Government has published a substantially restructured National Planning Policy Framework (NPPF), replacing the previous Framework and introducing a clearer separation between policies for plan-making and policies for determining planning applications.
Although many familiar planning principles remain, the August 2026 NPPF contains a number of important changes which will affect local authorities, developers and landowners.
A more structured planning system
One of the most noticeable changes is the organisation of the Framework itself.
The NPPF now separates plan-making policies from national decision-making policies, making it clearer which policies apply when preparing Local Plans and which should be used when determining individual planning applications.
The Government continues to emphasise that the planning system should be genuinely plan-led, with authorities expected to keep their development plans up to date.
Local Plans will sit beneath the emerging system of Spatial Development Strategies, which are intended to deal with strategic matters including housing requirements, major infrastructure and broad locations for growth.
A stronger emphasis on housing delivery
The Framework continues the Government's objective of significantly increasing housing delivery.
Development plans are expected to meet identified development needs wherever possible, while local authorities must maintain a supply of deliverable housing sites.
Importantly, the NPPF gives substantial weight to the benefits of providing homes which meet evidenced housing needs.
There is also specific support for a broader mix of housing sites, including small and medium-sized developments, rather than relying exclusively on large strategic allocations.
Grey belt becomes firmly embedded in national policy
The rules for grey belt have largely staid the same however grey belt is now firmly incorporated into both plan-making and decision-making.
Grey belt includes previously developed Green Belt land and other Green Belt land which does not strongly contribute to three particular Green Belt purposes:
checking the unrestricted sprawl of large built-up areas;
preventing neighbouring towns from merging; and
preserving the setting and special character of historic towns.
The Framework also introduces a more detailed methodology for councils when assessing Green Belt land.
This could be important where older Green Belt studies have assessed very large parcels of land without considering whether smaller individual sites perform differently.
We will look at the grey belt provisions in more detail in a separate article.
New opportunities around railway stations
The NPPF introduces a much stronger approach to development around well-connected railway and tram stations.
Residential and mixed-use development within reasonable walking distance of qualifying stations may now benefit from specific national policy support, including in some Green Belt locations.
The Framework also introduces minimum residential densities around well-connected stations, reflecting the Government's intention to make more efficient use of highly accessible land.
Perhaps most significantly, where a development plan identifies suitable land around a well-connected station, exceptional circumstances do not have to be demonstrated to justify altering Green Belt boundaries.
We will examine these station-related provisions separately because they could have significant implications for land around existing transport hubs.
Greater emphasis on making efficient use of land
The Framework strengthens the requirement to make efficient use of available land.
Higher densities are encouraged in accessible locations and development within settlements is expected, in general, to increase the density of the surrounding area unless there is a clear justification for not doing so.
This represents a further move away from simply reproducing existing development densities where a site could reasonably accommodate more development.
Infrastructure and viability
The Framework also seeks to provide greater certainty about infrastructure and affordable housing contributions.
Local Plans should establish clear requirements which can be reflected in land values from the outset.
The Government's expectation is increasingly that viability issues should be addressed through plan-making rather than renegotiated when individual applications are submitted.
For major residential development on Green Belt land, the Golden Rules remain particularly important, covering affordable housing, infrastructure and accessible green space.
What does the new NPPF mean in practice?
The August 2026 NPPF is not simply a rewrite of existing policy.
It reflects a wider change in the Government's approach to planning: encouraging more housing, making greater use of sustainable locations, requiring more efficient use of land and taking a more strategic approach to Green Belt review.
For landowners and developers, this means sites which may previously have appeared difficult to develop should be reassessed against the new policies.
Equally, the Framework introduces additional requirements which need to be considered at an early stage, particularly around affordable housing, infrastructure, density and sustainability.
Over the coming weeks we will look in more detail at three particularly important areas:
Grey Belt – what the new rules mean for Green Belt land
Development Around Railway Stations – understanding the new station policies
Housing Delivery and Small & Medium Sites – where the new opportunities may arise
