The updated National Planning Policy Framework (NPPF) has now been published, following consultation on the December 2025 draft: National Planning Policy Framework 2026.
The government’s target of building 1.5 million homes during the current parliamentary term continues to put planning reform firmly in the spotlight. The latest NPPF reforms sit at the heart of Labour’s wider reshaping of the planning system: it is a clearer, more directive framework designed to support housing delivery, infrastructure investment and economic growth.
Published on 17 August 2026, the revised NPPF represents the most significant overhaul of national planning policy since the framework was introduced in 2012.
That is largely because the framework is now split between plan-making and decision-making policies, with coded sections covering topics such as housing, Green Belt, settlement growth and infrastructure.
Strategic planning returns through Spatial Development Strategies (SDSs), introduced by the Planning and Infrastructure Act 2025. The new NPPF builds on that statutory framework by adding detail on the content of SDSs and confirming that they must establish a positive, sub-regional framework for investment and growth over a minimum 25-year period.
Local plans are expected to support a broader mix of housing delivery, including allocating at least 10% of housing requirements on sites of one hectare or less and a further 10% on sites between one and 2.5 hectares, strengthening opportunities for SME builders.
Significant weight is given to strategic employment development and sectors aligned with the Government’s Industrial Strategy, including advanced manufacturing, logistics, energy infrastructure, laboratories, data centres and AI Growth Zones.
The headline here is that homes in existing urban areas close to transport hubs, delivered at high density, are supported. That is largely thanks to new support for residential and mixed-use development within reasonable walking distance of well-connected railway stations, creating a clearer route to development in sustainable, transport-connected locations.
The revised Standard Method remains the basis for assessing housing need and local authorities are expected to plan positively to meet identified need.
The paragraph 11 presumption and tilted balance have been replaced by new national decision-making policies s4 (development within settlements) and s5 (development outside settlements). Now, development within settlements should be approved unless adverse effects substantially outweigh the benefits. Development outside settlements may also benefit from policy support in specified circumstances, including where authorities cannot demonstrate a five-year housing land supply or have Housing Delivery Test results below 75%.
Accessibility and inclusivity expectations have been strengthened, with plans expected to seek at least 40% of homes on major developments to meet M4(2) accessible and adaptable standards, subject to local evidence and viability considerations. Alongside that, the new policy TR4 states that the arrangement of streets and other routes should help create places that are safe, inclusive and attractive for all users.
Following a campaign by members of parliament to introduce consideration of safety for women and girls in the NPPF, the new policy DP3 on public space states that well-designed places should include spaces that are “safe, secure, inclusive, and accessible for all ages and abilities including for groups such as women and girls”.
The Government has retained its Grey Belt reforms. The definition has been simplified to land that “does not strongly contribute to any of purposes (a), (b), or (d)” — removing the previous reference to footnote 7 and the restrictions it imposed.
The Golden Rules and affordable housing additionality requirements remain, and those are aided by guidance at a new Annex E in relation to Green Belt assessments and grey belt identification. Whilst grey belt land is still actively promoted for development, these changes do not overcome the need for detailed analysis of whether land classifies as such, and the five core purposes of the green belt remain.
For local authorities requiring developers to go above and beyond on Biodiversity Net Gain delivery whether requiring 20% gains in local plans, or 80-year maintenance requirements in planning obligations, they must now justify those demands with robust evidence.
Protections for National Parks, National Landscapes and other designated landscapes have been strengthened compared with the consultation draft, reinforcing the need to conserve and enhance these areas.
Climate adaptation is embedded more explicitly throughout the framework, with increased focus on flood risk, drought, overheating, wildfire risk, coastal change, green infrastructure and nature-based solutions.
Tree protections remain prominent, but the final position is less expansive than some expected. The December 2025 draft had proposed widening the definition of veteran trees, which some suggested could have captured significantly more trees and materially affected site layouts through associated root protection zones. That change has not been carried through: the final definition remains focused on trees of exceptional biodiversity, cultural or heritage value. Ancient woodland and ancient and veteran trees remain strongly protected, but without the wider scope feared by some. The framework also places greater emphasis on retaining and integrating established trees, hedgerows and natural features into scheme design.
National policy strengthens support for renewable energy generation, electricity networks, water supply, wastewater infrastructure and reservoir development, reflecting the Government’s focus on development to support economic growth and resilience.
One of the more unexpected additions is the clearer support for new reservoir development, with water infrastructure now treated as a central growth and resilience issue rather than a more peripheral utilities concern. This is likely to be significant for strategic sites and local plans in areas where housing or employment growth is constrained by water supply or network capacity.
Greater weight is afforded to infrastructure and development that supports economic growth, productivity and strategic national priorities.
For developers, the direction of travel is clear. The revised NPPF strengthens commitment to housing delivery and economic growth, gives greater support to sustainable and well-connected development, and opens up fresh opportunities for land within settlements, near transport hubs and in locations capable of meeting housing or economic need.
Developers should focus their proposals to support sustainable growth, housing delivery, infrastructure provision and environmental enhancement, whilst ensuring that the impacts of their schemes are adequately mitigated. If sites have previously been constrained by policy or local plan uncertainty, now is the time to revisit your prospects of securing a permission (particularly if they are close to train stations) and seek advice on whether those have now improved.
