England's new National Planning Policy Framework was published on 17 August 2026. It changes both the organisation of national policy and several substantive tests. This update compares the final August document with the official December 2024 predecessor, rather than treating consultation proposals as the final policy.
The comparison is selective: it concentrates on matters relevant to residential and smaller development, and on the transition between versions. Read the current framework for the complete policy and our NPPF reference guide for the basic relationship between national policy, local plans and legislation.
The documents compared
We checked the August 2026 PDF and the official archived December 2024 PDF. The latter is the version captured by the National Archives in February 2025. Old GOV.UK asset links can redirect to the latest publication, so a link containing “2024” is not sufficient evidence of which text has been read.
References below identify both sides of the comparison. They are an aid to checking an existing project file, not a substitute for reading the relevant policy, definitions and footnotes together.
1. Plan-making and decision-making are separated
The December 2024 framework used consecutively numbered paragraphs and frequently addressed planning policies and decisions together. The August 2026 framework introduces named policy identifiers and separates plan-making from national decision-making policies within thematic chapters.
The practical change is explicit: introduction paragraph 8 says the plan-making policies should not be used in decisions on development proposals. Annexes form part of national policy; introductory chapter objectives provide context rather than substantive tests. An old report cannot be updated safely by replacing “December 2024” with “August 2026” in its heading.
Action: identify whether each citation supports preparing a plan or deciding an application, then replace it with the relevant current provision where that version applies.
2. The presumption now turns on settlement location
December 2024 paragraph 11(c)–(d) contained the familiar decision-taking presumption, including the approach where there were no relevant development-plan policies or the most important policies were out of date. August 2026 policies S3–S5 introduce a different structure:
| Location | August 2026 starting point |
|---|---|
| Within a settlement | S4: approval unless benefits would be substantially outweighed by adverse effects assessed against national decision-making policies |
| Outside a settlement | S5: specified development categories and the applicable balancing provisions |
| Straddling a settlement boundary | S3(2): apply the respective policies to the relevant parts before the overall assessment |
| Green Belt or Local Green Space | S5(5) directs the reader to the relevant HC8 and GB policies and explains the balance where development is not inappropriate |
This does not mean that being inside a settlement removes heritage, flood-risk or other policy tests. S4 itself identifies circumstances relevant to the balance. Outside settlements, S5 includes qualifications to its categories and a separate approach to proposals outside those categories.
Action: check settlement status and the full policy route before recycling an old paragraph 11 assessment.
3. Inconsistent local policies receive a more explicit weighting instruction
December 2024 paragraph 232 said the weight given to existing policies depended on their degree of consistency with the framework. August 2026 Annex A paragraph 2 says materially inconsistent development-plan policies, or parts of them, should receive very limited weight, with an exception for policies examined and adopted or made against the new framework.
Other policies should not receive reduced weight solely because they predate publication. The statutory development-plan starting point also remains: section 38(6) has not been displaced by the framework.
Action: identify the specific inconsistency and relevant part of a policy. Do not describe an entire adopted plan as cancelled or irrelevant.
4. Station-related development has defined tests and density figures
The December 2024 framework addressed efficient land use and minimum densities in paragraphs 124–130, including a role for plan policies in accessible locations. The new framework adds explicit national figures in L3(2)(c): qualifying residential or mixed-use schemes near a well-connected station should achieve at least 35 dwellings per hectare, or 45 where service frequency is at least twice the minimum required by the definition. These figures concern the net developable area. The stated exceptions concern qualifying sub-major sites where meeting the standard is inappropriate or impossible, and traveller sites.
The glossary matters. “Well-connected station” includes geographic and service-frequency requirements; “reasonable walking distance” is not a universal straight-line radius. S5(1)(h) and GB7(1)(h) have further tests for the station-related development they address, including physical relationship and infrastructure capacity.
Action: verify the route, station definition, actual walking relationship, applicable site area and complete policy tests. “Near a station” is not a standalone permission or a reason to omit a Green Belt assessment.
5. New local-plan expectations are expressed differently
December 2024 paragraph 22 required strategic policies to look ahead at least 15 years from adoption. August 2026 PM2 sets the new local-plan period at no less than ten years from adoption, while PM1 gives spatial development strategies a horizon of at least 25 years. These are different plan functions; describing the change simply as “all plans shortened to ten years” would be misleading.
PM2 also expects preparation and adoption within 30 months of publishing Gateway 1 self-assessment. PM6 addresses duplication of national decision-making policy and searchable digital publication. These provisions apply subject to the transition rules: they do not automatically restart every examination already underway.
Which version applies, and when?
The August framework's Annex A is essential:
- Decisions: the policies are material considerations from publication, 17 August 2026 (paragraph 1).
- New-system plans: the local, minerals and waste, and supplementary plans described in paragraph 4 use the new framework.
- Spatial development strategies: paragraph 5 applies the new framework.
- Neighbourhood plans: those submitted under Regulation 15 on or before publication retain the December 2024 framework for preparation; the qualifying body may withdraw and update them (paragraph 6).
- Other plans: December 2024 continues to apply, including relevant earlier transitions preserved through its Annex 1 (paragraph 8).
The preserved December 2024 provisions include the particular Regulation 19, submission and other circumstances in paragraphs 234–239. They need a plan-specific history. The national framework's transition and the transition between the 2012 and 2026 plan-making regulations are separate questions. See local-plan examinations.
A statutory reference can still mean December 2024
SI 2026/313, effective 9 April 2026, inserted an express December 2024 NPPF definition into the GPDO and revised specified references. The latest framework's publication does not itself substitute August 2026 for that statutory definition. Check the actual prior-approval provision and current legislation before selecting a policy version.
Likewise, this NPPF revision does not enact larger householder permitted development limits. Our PD rule changes register distinguishes legislation already effective from consultation proposals.
What should change in an existing project file?
Hypothetical example: a planning statement prepared in July 2026 awaits a decision in September. Its author should review the relevant new decision policies and Annex A, identify any changes to the planning balance and update evidence where necessary. The answer is not automatically to withdraw the application, and it is not enough to change the document date.
For each affected issue, retain the old citation, current counterpart, reason it matters and proposed response. Where the interpretation is material to project viability or an appeal, obtain appropriate professional advice rather than relying on a general update.
