The Government's revised National Planning Policy Framework (NPPF), published on 17 August 2026, represents the most significant overhaul of national planning policy since the Framework was first introduced in 2012.

Following consultation on a draft published in December 2025, the new NPPF forms a central part of the Government's ambition to deliver 1.5 million homes during the current Parliament, while also supporting economic growth, infrastructure delivery and strategic investment.

For developers, landowners, local authorities and planning professionals, the changes are substantial. 

The revised Framework introduces a new structure, replaces the familiar "tilted balance", strengthens support for development in sustainable locations, and reshapes the relationship between local plans and national policy.

This article highlights the key changes and explores what they may mean in practice.

A New Structure for National Planning Policy

One of the first things users will notice is that the NPPF has been fundamentally reorganised. Rather than being structured around numbered paragraphs, the Framework now separates plan-making policies from national decision-making policies, using a series of named policy codes such as S3-S6, DP3, DM1 and TR4.

This may seem like a drafting change, but it has practical consequences. Existing appeal decisions, committee reports, planning opinions and legal agreements frequently reference specific NPPF paragraph numbers. Those references may now be of limited value unless they are checked against the new policy framework.

The End of the “Tilted Balance”

Perhaps the most significant change is the removal of the long-established paragraph 11(d) tilted balance. In its place, the Framework introduces a series of new policies:

• S4 provides strong support for development within settlements, stating that proposals should generally be approved unless adverse impacts substantially outweigh the benefits.
• S5 deals with development outside settlements, identifying categories of development that are acceptable in principle and retaining a route for exceptional circumstances.
• S6 provides enhanced protection for qualifying, up-to-date neighbourhood plans.

Importantly, a failure to demonstrate a 5 year housing land supply, or a Housing Delivery Test result below 75%, no longer automatically triggers the previous paragraph 11 mechanism. Instead, under the new framework, those factors become evidence of unmet housing need that may be relevant when applying policy S5.

The practical effect is that decision-makers will need to undertake a different planning balance exercise from the one that has dominated planning appeals for the last decade.

Local Plan Policies Could Carry Less Weight

One of the most consequential changes can be found in Annex A.

The revised Framework states that development plan policies which are materially inconsistent with the new national decision-making policies should generally be given very limited weight, unless the relevant local or neighbourhood plan has itself been examined or made under the August 2026 Framework. 

This is a notable shift from the current arrangements.

Historically, debates often focused on the age of a local plan. Under the revised approach, the key question is whether a policy is substantively aligned with current national policy, regardless of when it was adopted.

For promoters of planning permissions this creates opportunities where restrictive local plan policies are difficult to reconcile with the intentions behind the new Framework.

A Major Boost for Development Near Stations

The revised NPPF places significant emphasis on directing development towards sustainable, well-connected locations. 

New policy support applies to residential and mixed-use development within approximately 800 metres (or a 10-minute walk) of “qualifying” railway, underground, tram and light rail stations.

Where the station qualifies, minimum density expectations apply:

• 35 dwellings per hectare as a baseline; and
• 45 dwellings per hectare where service frequency is at least double the qualifying minimum.

A separate Green Belt route also applies to certain station-related development, making this an area worth checking carefully for sites near transport hubs.

The Framework also introduces a new "medium development" category, covering housing schemes of 10 to 49 dwellings on sites of up to 2.5 hectares, intended to give small and medium-sized developers greater visibility in national policy. 

Local plans are also expected to allocate at least 10% of housing requirements on sites of 1 hectare or less, and a further 10% on sites between 1 and 2.5 hectares.

New Definitions of "Settlement" and “Strategic Site”

The Framework introduces a national definition of a settlement, encompassing not only existing built-up areas but also allocated or permitted land that will form part of those settlements. A new definition of strategic site has also been introduced. For residential-led development, this will typically mean schemes of 1,500 dwellings or more.

The designation is significant because strategic sites are now treated differently across various plan-making, infrastructure and viability policies.

Green Belt and Grey Belt Reforms Continue

The grey belt reforms introduced in December 2024 remain firmly embedded within the new Framework.

The definition of grey belt land has now been simplified, removing an earlier footnote qualification and focusing on whether land makes a strong contribution to Green Belt.

The Government's Golden Rules and affordable housing additionality requirements remain in place, supported by new guidance.

However, grey belt designation is still not automatic. Landowners and developers will need robust evidence demonstrating why land does not strongly contribute to the relevant Green Belt purposes.

Increased Support for Infrastructure and Growth Sectors

The Framework also strengthens support for renewable energy generation, electricity networks, water supply and waste water infrastructure. 

Reservoir development, including on-farm reservoirs, receives clearer support, reflecting water supply and drought resilience concerns. 

Significant weight is also given to strategic employment uses aligned with the Government's Industrial Strategy, including advanced manufacturing, logistics, laboratories, data centres and AI Growth Zones.

Other Notable Changes

Major development proposals must now be accompanied by a concise planning statement under new policy DM1, addressing consistency with development plan and national policy, the outcome of pre-application engagement and the intended use of planning obligations. 

Policy on protecting public houses and other valued community facilities has also been strengthened, generally requiring at least 12 months of unsuccessful marketing evidence before loss on viability grounds will be accepted.

What Does This Mean in Practice?

The revised NPPF clearly signals the Government's intention to accelerate housing delivery while directing growth towards sustainable and well-connected locations.

For developers and landowners, opportunities may emerge where local plan policies conflict with the new national framework, particularly for sites near qualifying transport hubs or within areas of housing need.

For local planning authorities, the message is equally clear: Local Plans need to be reviewed and updated quickly. Policies that are inconsistent with the new Framework could now carry substantially less weight in decision-making processes.

Given the scale of the reforms, organisations with live planning applications, promoted sites, allocations or emerging local plans should review their position as soon as possible, particularly in relation to housing land supply, Green Belt and grey belt considerations, and development opportunities close to major transport infrastructure.
