Emerging local plans and the weight they carry

The weight of an emerging local plan is a matter for the decision taker, and national policy gives three tests to apply: the stage the plan has reached, the extent of unresolved objections to the relevant policies, and the degree of consistency with the Framework. All three operate together. A policy at submission stage with no objections and clear Framework consistency can carry real weight. The same policy at the same stage, with forty representations against it and a soundness question hanging over it, carries very little.

That is the whole of the law on the point, and it is deceptively short. The practical skill is arguing stage, objections and consistency separately, because officers and inspectors routinely collapse them into a single sentence about the plan being at an advanced stage.

Plan-making stages and what each means

The statutory framework is the Town and Country Planning (Local Planning) (England) Regulations 2012, with the plan submitted for examination under section 20 of the Planning and Compulsory Purchase Act 2004 and adopted under section 23.

The stages that matter for weight:

1. Regulation 18 consultation on issues and options, and on the preferred approach. Policies at this stage are drafts in the ordinary sense and carry almost no weight.
2. Regulation 19 publication of the submission version for representations. The authority has settled its position, so the policies are no longer moving, but nobody has tested them.
3. Submission to the Secretary of State and the appointment of an inspector.
4. Hearing sessions, during which the inspector's questions and the authority's responses become public.
5. Consultation on main modifications proposed by the inspector.
6. Receipt of the inspector's report, then adoption by the authority.

Weight rises across that sequence, and it rises unevenly. The two moments where it jumps are the close of hearings on the relevant policy and the publication of main modifications, because both tell you what the inspector thinks.

How weight increases through examination

Before the hearings, you are arguing about a policy nobody independent has examined. After them, you can point to what the inspector said in the session, to the authority's written responses, and to any post-hearing note. That is evidence rather than assertion.

So the practical question on any emerging policy is narrow: has this specific policy been examined yet, and what came out of it. A plan can be at an advanced stage overall while the particular policy you care about is still subject to a live soundness objection. Weight attaches to policies, not to plans.

Treat that table as a sketch of how the tests usually play out, not a formula. The decision maker has to apply the three tests to the facts.

Unresolved objections and their effect

An objection reduces weight only if it goes to the policy you are relying on, and only while it remains unresolved. Two refinements matter.

First, the objection has to be live. An objection withdrawn at the hearing, or accepted by the authority in a statement of common ground, is resolved. Check the examination library rather than relying on the Regulation 19 representations schedule, because positions move during examination and the library is where that movement is recorded.

Second, the content of the objection matters more than the number of objectors. Fifty residents objecting to a site allocation on amenity grounds is a political fact. One objection from a statutory consultee saying the policy is inconsistent with national policy on flood risk is a soundness problem, and it is the second that suppresses weight.

Main modifications and when they bind

Main modifications are the inspector's proposed changes needed to make the plan sound. They are consulted on, usually for six weeks, and the inspector considers the responses before reporting.

Once modifications are published, the sensible position is to argue the modified wording rather than the submitted wording. The authority will be doing the same. A planning statement that quotes the submitted policy after modifications have changed it looks careless, and officers read the examination library even when applicants do not.

Modifications can also work in an applicant's favour. Where an inspector has proposed deleting a restrictive policy or widening an exception, that proposed deletion is a material consideration from the day it is published, and it cuts against the authority continuing to apply the submitted version.

Arguing for or against emerging policy

Decide which direction you are arguing in, then build the case around the three tests rather than around the plan's overall progress.

If you want weight given to an emerging policy, show that it has been examined, that objections to it are resolved, and that it reflects national policy. Quote the examination document by reference and date. If you want weight withheld, identify the live objection, attach the representation, and explain the soundness issue in a sentence an officer can repeat in a committee report.

There is a third move that is often stronger than either. Where the emerging plan and the adopted plan point the same way, say so and rely on the adopted plan, because section 38(6) of the 2004 Act gives it primacy and you then do not need the weight argument at all. Where the adopted plan is out of date, the housing land supply position usually does more work than the emerging plan does.

An illustrative example

Illustrative only: a 48 dwelling scheme on a site allocated in an emerging plan that has completed hearings, with main modifications consulted on but the inspector's report not yet received. The allocation itself attracted no objection and was not modified. A separate emerging policy requiring 40 per cent affordable housing attracted viability objections from three developers, and the inspector proposed a modification adding a viability exception. The applicant argues substantial weight for the allocation, limited weight for the submitted affordable housing figure, and substantial weight for the modified wording with its exception. Same plan, three different weight positions, each sourced to a document in the examination library.

Inspectors' treatment of emerging plans

Appeal decisions are indicative of how inspectors have approached an issue rather than binding precedent, and the pattern is consistent on one point: inspectors are reluctant to let an emerging plan determine an appeal where doing so would pre-empt the examination.

That reluctance is strongest where the emerging policy would be the reason for refusal. But it is weaker where the emerging policy supports the proposal, because granting permission consistent with an emerging allocation does not prejudice the plan process in the same way. Expect that asymmetry and plan the case around it.

Prematurity arguments run into the same difficulty. National guidance sets a high bar: refusal on prematurity grounds needs the proposal to be so substantial, or its cumulative effect so significant, that granting permission would undermine the plan-making process. For most applications below strategic scale it is not a serious argument.

Timing an application around adoption

Three timing choices come up repeatedly.

Submitting before adoption, to be determined under the adopted plan, makes sense where the adopted plan is more permissive. Hold the eight or thirteen week clock in mind, because determination after adoption is determination under the new plan regardless of when you applied.

Waiting for adoption makes sense where the emerging allocation is the basis of the scheme. The risk is slippage, and plan programmes slip routinely.

Applying during the modifications consultation is the awkward middle, and it is where most of the weight arguments I see are actually deployed. Put the examination documents in the application pack, not just references to them, and set the weight argument out in the Planning Statement rather than leaving the officer to find it.

Whether a neighbourhood plan also covers the site is a separate check, and a made neighbourhood plan forms part of the development plan in its own right. For reform affecting plan-making itself, the planning law updates timeline is the place to follow what has taken effect.
