NPPF transitional arrangements and which edition applies
Three Framework editions in under three years has made transitional wording a live issue. Here is how it works for plans at examination, live applications and appeals.
NPPF transitional arrangements decide one thing: which edition of the Framework a plan or an application is tested against when the policy changes mid-process. The general rule for decision-taking is that the version in force on the day the decision is made applies, not the version in force when the application went in. Plan-making is different, and that is where the transitional wording does its real work, because an examination that has been running for two years cannot sensibly be restarted every time a new edition appears.
As at 9 October 2026, the current Framework is the edition published on 17 August 2026, which replaced paragraph numbering with policy codes. The December 2024 edition preceded it and itself renumbered the December 2023 text. Three editions in under three years is why this question keeps coming up.
What a transitional provision is doing
A new Framework is government policy, not legislation. It takes effect as a material consideration from the moment it is published, and nothing in the Town and Country Planning Act 1990 requires a transitional period at all. The transitional wording exists because ministers accept that abrupt change would waste public money on half-finished local plans and would be unfair to applicants who built a case on the previous text.
Typically that wording appears in a short annex or in footnotes to the first chapter, and it does three jobs. It says which plans continue to be examined under the previous edition. It sometimes gives a short grace period before particular policies bite on decisions. And it tells plan-makers what to do about housing figures calculated under an earlier method.
Those provisions are the only source of transitional protection. There is no general principle that a scheme is judged by the policy in force when it was submitted, and arguing otherwise is a quick way to lose an appeal.
Plans already at examination
The usual mechanism fixes a cut-off by reference to submission for examination under section 20 of the Planning and Compulsory Purchase Act 2004. Plans submitted before the stated date are examined against the old Framework. Plans submitted after it are examined against the new one.
That produces some awkward outcomes. A plan submitted a fortnight before the cut-off can be adopted against policy the government has already replaced, and it then forms part of the development plan for the purposes of section 38(6) for several years. Objectors at examination will say the plan is already out of date. Inspectors tend to reply that the transitional provision says what it says.
Where a plan is at an earlier stage, Regulation 19 consultation or earlier, authorities normally have to respond to the new edition before submission. The practical choices are to delay submission and rework the evidence, to submit quickly under the old regime, or to proceed and accept main modifications at examination. Each has a cost, and our note on plan-making reform and what happens to emerging plans looks at how the Levelling-up and Regeneration Act 2023 changes the calculus.
The reform to plan-making under that Act adds a second transition running alongside the Framework one, with its own commencement dates for the new plan-making system and for National Development Management Policies. Two transitions overlapping is the current state of play, and it rewards reading the commencement regulations rather than the press notice.
Decision taking in the interim
For applications and appeals the position is simpler to state and harder to live with. The decision-maker applies the development plan and then the Framework as it stands on the day of the decision.
So a case officer who started drafting a report in July against the December 2024 text has to rewrite the policy section before the committee meets in September. An applicant whose planning statement cited paragraph numbers from the superseded edition will find the report says the statement is based on policy no longer in force, which is a bad look even where the substance is unchanged.
The tilted balance is where this bites hardest. Where the policies most important for determining the application are out of date, the presumption in favour of sustainable development applies and permission should be granted unless specified harms outweigh the benefits. The policy code for that presumption changed with the August 2026 edition, so take the code from the current text rather than from an old appeal decision or a precedent document.
Grace periods, where they exist, are narrow and specific. They tend to attach to a single new requirement rather than to the Framework as a whole, and they are stated in days or months. Read the actual words; do not assume a general moratorium.
Housing requirement figures during the change
Where the standard method for assessing housing need is altered, the transitional wording usually tells plan-makers whether to use the old or new figure and for how long. That provision draws the most attention, because the number drives the land supply calculation and with it the tilted balance.
For decision-taking, the relevant questions are whether the authority can demonstrate the required supply and whether the Housing Delivery Test result triggers consequences. Both are measured against the requirement in force, and an authority mid-transition may be working to a figure that is about to change.
| Stage | Which edition usually applies |
|---|---|
| Plan submitted for examination before the cut-off | Previous edition, as stated in the transitional wording |
| Plan submitted after the cut-off | New edition |
| Application determined after publication | New edition, subject to any stated grace period |
| Appeal decided after publication | New edition, with parties invited to comment |
| Plan already adopted | Unaffected, and applied under section 38(6) |
How inspectors handle an edition change mid-appeal
Where a new edition lands during an appeal, the Planning Inspectorate's practice is to write to the parties inviting representations on the implications. Take that invitation seriously and answer it in substance.
What works is a short note mapping your original policy argument onto the new text, saying which conclusions are unaffected and which need adjusting, and explaining the consequence if the balance has shifted. What does not work is a statement that the new edition makes no difference, offered without analysis, when the appellant's whole case rested on a policy that has been rewritten.
Inspectors decide on the policy in force at the date of their decision, and a decision issued the day after publication will apply the new edition. Recovered appeals and called-in cases are the same.
Working out which edition applies to your case
Five checks, in order:
- Find the current Framework on gov.uk and note the publication date on the front page.
- Read the transitional annex or footnotes in full, not a summary of them.
- Identify the stage your plan or application has reached, and the date on which that stage was reached.
- Check the commencement position for the plan-making reforms and for National Development Management Policies, because these sit outside the Framework.
- Check whether the development plan policies you rely on predate the Framework and whether any have been superseded.
Commencement provisions in secondary legislation work the same way and are just as easy to misread, something we cover in commencement notices and the CIL amendment regulations. The planning law timeline on this site is a reasonable place to follow what has moved: see UK planning law updates.
Recording the edition you relied on
This is the discipline that saves arguments later. Every planning statement should name the Framework edition and its publication date at the top of the policy section, and cite policy by the code used in that edition.
Three habits worth building:
- Quote the policy text as well as the code, so a reader can follow the argument even after the next renumbering.
- Date every policy reference where the development plan policy itself is under review.
- Keep a dated copy of the Framework you used, because gov.uk replaces the published document and the old version is not always easy to retrieve.
And resist the temptation to copy paragraph numbers out of an older document or a precedent statement. The December 2024 renumbering and the August 2026 move to policy codes mean that a number carried forward from an old template is now almost certainly wrong, and a case officer who spots one will discount the rest of the document.
This is general guidance, not legal advice; transitional wording differs between editions, so read the current Framework on gov.uk and check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
Which Framework edition applies to my application?
The one in force on the day the decision is made, not the day you submitted. If a new edition is published while your application is pending, the case officer must apply the new text, subject to any grace period stated in the transitional wording. Update your policy section rather than waiting to be told.
Does a new Framework restart a local plan examination?
Usually not. Transitional provisions normally fix a cut-off by reference to the date a plan was submitted for examination under section 20 of the Planning and Compulsory Purchase Act 2004. Plans submitted before that date continue to be examined against the previous edition, even though the government has already replaced it.
What happens if the edition changes during an appeal?
The Planning Inspectorate normally writes to the parties inviting representations on the implications. Answer in substance by mapping your case onto the new text and saying which conclusions change. The inspector decides on the policy in force at the date of the decision, so a late change can affect the outcome.
Can I rely on the policy in force when I submitted?
No. There is no general principle that an application is judged against the policy in force at submission. The only transitional protection is what the Framework's own wording provides, and that is usually directed at plan-making rather than decision-taking. Any grace period for decisions will be narrow and expressly stated.
Why did paragraph numbers stop working?
The Framework was renumbered in December 2024 and then re-issued on 17 August 2026 with policy-coded chapters in place of paragraph numbers. A citation carried forward from an older template will not match the current text. Cite by the code used in the current edition and quote the wording you rely on.
