Taking apart a reason for refusal

A reason for refusal planning notice has to be read as a set of separate claims, not as a verdict. Each reason typically contains a policy citation, a factual assertion about the proposal, a judgement about harm, and sometimes an evidential gap dressed up as a harm. Those four parts are answered in completely different ways. Take a refusal apart into its components and the strategy usually becomes obvious: this one is a redesign, this one is a missing document, this one is an argument we can win, and this one the council will drop.

The Development Management Procedure Order 2015 requires the authority to state clearly and precisely its full reasons for refusal, including the relevant policies. That duty is the lever. A reason that does not say what it means is a weaker reason.

Anatomy of a reason

Take a typical refusal of a two-storey rear extension in a conservation area. The reason will usually read something like: the proposed development, by reason of its scale, depth and design, would be an incongruous addition that fails to preserve the character and appearance of the conservation area, contrary to policies X and Y of the adopted local plan and the Framework.

Four components sit inside that.

The factual premise: the extension has a particular scale, depth and design. Facts can be wrong. Officers measure from the wrong drawing, describe a two-storey element as three-storey, or state a depth that does not match the submitted plan.

The planning judgement: that the addition is incongruous and fails to preserve character. This is the officer's assessment, and the only ways to answer it are better evidence, a redesign, or an inspector's different view.

The policy hook: policies X and Y. These need checking, because they are frequently the weakest part.

The statutory overlay, in a conservation area case: section 72 of the Planning (Listed Buildings and Conservation Areas) Act 1990 and the duty to pay special attention to preserving or enhancing character and appearance. Where the refusal engages a statutory duty, the answer has to work through that duty rather than around it.

Separating policy from judgement

Write the reason out, then split it into two columns: what the council says the scheme does, and what the council says follows from that in policy terms.

The first column is testable. If the council says the extension projects 4 metres, measure it. If it says the proposal would overshadow the neighbouring garden for most of the day, model it. Factual claims that can be disproved are the best material in any appeal, because they damage the credibility of the rest of the reason.

The second column is judgement, and judgement is answered by evidence rather than by disagreement. An assertion that a scheme is out of keeping is met with a street character analysis showing what is actually there: the range of extension depths on the terrace, the roof forms, the materials, the precedents with their application references. Officers respond to that, and so do inspectors.

The move to avoid is replying to judgement with more assertion. A statement that the design is in fact appropriate, with no analysis attached, changes nothing.

Checking the policy references

This is the half hour that most repays itself, and it is skipped constantly.

For each cited policy, check five things.

1. Is the policy still adopted? Plans get superseded, and a refusal citing a policy from a plan replaced six months earlier is in difficulty.
2. Does the policy say what the reason implies? Read it in full rather than from the officer's summary. Policies cited for a design harm often turn out to be about something adjacent.
3. Is the policy in the development plan at all, or is it from a supplementary document or a design guide? The weight differs, and an SPD cannot carry the weight of an adopted plan policy.
4. Where the Framework is cited, which edition and which policy? The Framework was re-issued on 17 August 2026 with policy-coded chapters replacing the paragraph numbering used in earlier editions, and refusal notices drafted from older templates still cite the old paragraph numbers. Quote the current edition and code.
5. Is the policy consistent with current national policy? A policy that is not may carry reduced weight, which feeds into the balance.

Where a reason cites four policies and only one actually supports it, say so explicitly in the appeal statement. It narrows the case and tells the inspector something about how the refusal was put together.

Identifying the evidential reasons

A distinct category of reason says, in effect, that the applicant failed to provide something. Insufficient information to assess the impact on protected species. No drainage strategy submitted. The effect on the highway network has not been demonstrated.

These are the good news reasons. They are answered by producing the document, and they do not require anyone to change their mind.

Two consequences follow. First, an evidential reason is usually a strong argument for a fresh application rather than an appeal, because an appeal on the same material will fail while an application with the survey attached will succeed. Second, where the council refused on information grounds without asking for the information, there may be a costs argument at appeal, since the Inspectorate's guidance treats refusing without giving the applicant an opportunity to supply straightforward information as potentially unreasonable.

Check whether the officer actually asked. The case file correspondence will show it, and our note on highway safety refusals and visibility splay evidence covers how the technical record is assembled on a highways refusal.

Deciding which to answer by redesign

Sort the reasons into three groups and the route chooses itself.

Where the reasons are mixed, which is usual, the question becomes whether the redesign needed to answer the design reason is acceptable to the client. A rear extension reduced from 4 metres to 3 metres may still work for the family. A scheme that loses a bedroom may not.

A fresh application has three advantages that are often underweighted: the free-go provision can remove the fee where the application is a revision of one refused within twelve months and meets the conditions, the determination period is weeks rather than months, and the appeal right remains available afterwards. Against that, a second refusal strengthens the council's position at any later appeal.

For heritage reasons, the statutory duties mean the analysis has to work through harm and public benefit in the right order, which our note on heritage harm refusals and the statutory balance sets out.

Building the case around the reasons

Whichever route you take, structure the response to mirror the refusal. One section per reason, in the council's own order, with the council's wording quoted at the head of each.

Inside each section: state what the reason claims, separate the facts from the judgement, answer the facts with measurement, answer the judgement with analysis, and state what has changed if anything has. Then say plainly whether the reason is accepted, partially accepted or disputed.

That structure does two things. It makes the officer's or the inspector's job easy, which is worth more than any rhetorical flourish. And it exposes any reason the council cannot support, because the gap shows up when the claims are laid out one at a time.

Before serving anything, ask the case officer which reasons the authority intends to defend. On refusals that went against an officer recommendation the answer is sometimes none of them with any enthusiasm, which changes the calculation entirely, as our note on committee refusals against officer advice explains.

The Planning Statement on the fresh application, or the statement of case on the appeal, is the document where this analysis lives. Write it reason by reason, and keep the drafting tight: an inspector reading forty pages of general policy narrative is looking for the part that answers the refusal.
