NPPF 2026: Key Planning Policy Changes & What They Mean for Development
James Firth
Aug, 17 2026The updated National Planning Policy Framework (NPPF) has today been published, Monday 17th August. Following the consultation held in December 2025 the revised NPPF includes a significant re-write of the previous version. The new document includes both policies for plan-making and policies for use in the determination of planning applications through national decision-making policies (NDMPs).
National Decision Making Polices
The use of national decision making policies should allow for greater consistency and predictability when progressing planning projects through reducing the variation seen in different local planning authority areas. Included within the policies is a national minimum number (40%) of accessible homes on major developments and stronger protections for community facilities.
Development Around Stations & Public Transport
The new framework takes forward the support for development around stations. The government making clear this will include a “default ‘yes’ for homes within reasonable walking distance of well-connected stations”.
The scope of this policy has been amended to cover the to the top 80 Travel to Work Areas (TTWAs) by Gross Value Added, as opposed to the top 60 TTWAs proposed in the consultation version of the NPPF.
Stations should be served in the daytime by at least four trains or trams per hour overall, or at least two trains or trams per hour in any one direction.
To be within ‘reasonable walking distance’ for this purpose the NPPF states this should be considered to be around 800 metres, or around 10 minutes’ walk time if topography, route availability and quality or physical barriers would prevent or discourage walking from up to 800 metres away.
Also proposed are new minimum expectations for how much housing should be built in these areas.
It is stated that the new framework will help ensure that planning decisions give proper consideration to the proximity of public transport links with this set to become even more important in planning decision making.
Consultation Requirements & Decision Making
The proposals seek to streamlining decision-making by aiming to make planning decisions faster and more proportionate. This includes reducing information requirements for smaller schemes, and changes to the requirements for consultations on applications. The previously announced changes to the national scheme of delegation to come into effect at the end of October 2026 will of course further reduce the need for schemes to be reported to Planning Committee through enabling more delegated level decisions.
Medium Scale Development
The NPPF takes forward the proposals to create a new category of “medium” development. This is defined as developments of 10 to 49 homes, with a site area of up to 2.5 hectares.
The government will shortly consult on standard s106 template for medium sites which it is stated is expected to become the default for applications in future.
Housing Delivery Test
Published alongside the document are the long awaited 2024 and 2025 Housing Delivery Test (HDT) results. These measurements of housing delivery in local authority areas are an important tool with implications for planning applications, given that a failure to provide sufficient delivery will have implications for the principle of development within and outside settlements.
The planning policy consequences of the Housing Delivery Test indicating that a local planning authority’s delivery has fallen below their housing requirement are set out in the National Planning Policy Framework as follows:
- Where delivery falls below 95% of the requirement over the previous three years, the authority should prepare an action plan to assess the causes of under delivery and identify actions to increase delivery in future years
- Where delivery falls below 85% of the requirement over the previous three years, a buffer of 20% should be added to the identified supply of specific deliverable sites. This is in addition to the requirements for an action plan
- Where delivery falls below 75% of the requirement over the previous three years, an evidenced unmet need for housing is deemed to exist for the purpose of applying policy S5(1)(j) in the Framework. This is in addition to the requirements for an action plan and 20% buffer.
Business, Commercial Development & Data Centres
The NPPF continues to place high importance on the need to support economic growth and business. The government stating that the changes will provide for stronger support for growth and infrastructure. Included as part of this are proposals for AI Growth Zones and support for data centres. The government have states the NPPF will “make it easier for councils to approve developments that create jobs, unlock investment, and deliver the shops, leisure facilities, clean energy and food production local areas need”.
Implementation & Transitional Arrangements
The revised NPPF is published today, Monday 17th August 2026, and will be immediately relevant for decision making on planning applications.
It is stated development plan policies (or parts of those policies) which are materially inconsistent with national decision-making policies in this Framework should be given very limited weight.
