Planning Appeals Explained

An appeal is not a complaint about the council and it is not a review of how the council behaved. It is a fresh determination of your application by somebody else, on the same policy, from the same drawings. Understanding that one sentence tells you most of what you need to know about when an appeal is worth making, and it explains the single fact that catches nearly everybody out: you cannot use an appeal to fix the scheme.

Who can appeal, and who cannot

The right belongs to the applicant alone.

The planning acts give a right of appeal to the person who made the application, against the council’s decision on it. Appeals go to the Secretary of State and are decided in practice by an inspector from the Planning Inspectorate, who is independent of the council and has usually never seen the site before.

Nobody else has that right. A neighbour who thinks permission should not have been granted has no appeal at all, which is covered with the rest of the consultation machinery in neighbour consultation and objections. Third parties who commented on the original application are notified that an appeal has been lodged, and the comments they already made to the council are passed to the inspector as part of the file.

On the fast track procedure used for householder extensions, those existing comments are all the inspector gets from them. There is no fresh round of objection, and a neighbour who did not write in at application stage generally does not get a second opportunity.

The things you can appeal against

Four different appeals wear the same name and behave differently.

A refusal is the obvious one. The council has said no, the decision notice gives its reasons, and you are asking an inspector to reach a different conclusion on the same proposal.

A condition can be appealed on its own, keeping the permission and challenging what has been attached to it. Read the next paragraph before doing that. Where the objection is that a condition is unnecessary or badly worded rather than legally objectionable, an application to the council to vary it is usually the quicker route, and both are set out in planning conditions explained.

Non determination is an appeal against the council failing to decide within the statutory period. It is available, it is rarely a good idea on a householder extension, and it costs you the council’s decision: you swap an officer who has visited your street for an inspector working from paper, and you give up the chance to negotiate an amendment.

A refused certificate is appealable too, and it is a different kind of argument, about fact and law rather than about planning merits. That sits with lawful development certificates. An enforcement notice has its own appeal with its own statutory grounds, which is a serious piece of litigation rather than a form.

The deadline is printed on your decision notice

There is one, it is shorter for householder appeals than for anything else, and it is treated as hard.

Every decision notice sets out the appeal rights that attach to it, including the period for lodging one. Read that section on the day it arrives rather than three weeks later. The period runs from the date on the notice, not from the day you opened the envelope or the day your agent forwarded it.

Householder appeals run on a much tighter deadline than other planning appeals, because the whole procedure is designed to be quick. The figures are revised from time to time and appear on the notice itself and on the Inspectorate’s own service, which is where to take them from rather than from any page written earlier. Assume you will not get an extension of time and work backwards from the date you are given.

Miss it and the appeal route is simply gone. What remains is a fresh application to the council, which is not a disaster and is often what you would have done anyway, but it is a decision you want to make deliberately rather than by default.

How a householder appeal is actually run

Written representations, no hearing, and a site visit.

Householder appeals are dealt with on a fast track written procedure. You submit the appeal with the original application documents, the decision notice and a statement of your case. The council submits its officer’s report and its own statement. Neither side gets to answer the other at length, because the procedure deliberately closes the exchange down.

An inspector then visits. Where the site can be seen adequately from public land the visit is unaccompanied and you may not know it has happened. Where it cannot, the visit is accompanied and both parties are invited, and the inspector will look but will not hear argument on the doorstep. That surprises people who have prepared a speech.

Larger and more contentious appeals can run as a hearing, which is a round table discussion led by the inspector, or as an inquiry with advocates and cross examination. Neither is available for a householder extension, and neither is something you want.

You cannot fix the scheme on appeal

The inspector decides the application that was refused, not the improved version you have since drawn.

This is the fact that decides most appeal questions. An inspector is determining the proposal as submitted to the council. Amendments are only entertained where they are so minor that nobody who commented on the original could be prejudiced by the change, which in practice means correcting a drawing rather than redesigning a roof. Reducing the depth by a metre to answer the reason for refusal is not a minor amendment. It is a different proposal, and it needs a different application.

So the question to ask before appealing is not whether the council was harsh. It is whether the scheme you actually want is the scheme that was refused. If the extension you would settle for is smaller, set further from the boundary, or roofed differently, an appeal is the wrong instrument, however unfair the refusal felt.

What the inspector is deciding, and what else is in play

The same statutory test, applied by someone with no local history.

An inspector applies the development plan for the area unless material considerations indicate otherwise, exactly as the case officer was required to. The inspector is not marking the council’s homework, and the officer’s reasoning carries no special weight. Points the council never raised can be taken into account, and points it made can be dismissed.

The appeal is a redetermination of the application rather than a review of the decision, and that has a consequence people miss on a conditions appeal. Reopening the permission puts the whole of it back in front of the inspector, who can impose different conditions from the ones the council chose. Appealing a condition you dislike is not a risk free way of testing it.

The decision, when it comes, replaces the council’s. If the appeal is allowed the inspector grants permission, with whatever conditions they consider necessary, and those conditions are yours to live with in the same way.

What you actually submit, and what an inspector responds to

A short statement that engages with the reasons for refusal beats a long one that does not.

The appeal itself is a form, the application documents, the decision notice and a statement of your case. That statement is the whole of your argument, because there is no hearing at which to add to it. Its job is narrow: take each reason for refusal in turn and explain, against the policies the council cited, why the harm alleged does not arise or is outweighed.

What does not help is the material every appeal statement seems to contain. The cost of the drawings, the time the process has taken, how the officer spoke to you, what a neighbour was allowed to build in 2009, and the household’s need for another bedroom are either not planning matters or carry very little weight. A section drawing showing the boundary relationship, or a photograph of the same roof form three doors down, is worth more than all of it.

Enforcement appeals are a different animal

Same tribunal, different statute, and the grounds are fixed by law.

Where a council serves an enforcement notice, the appeal against it runs on defined statutory grounds rather than on general argument. Those grounds include that planning permission ought to be granted for what has been built, that the notice is defective or the requirements excessive, and that the time limits for enforcement have already expired. Running the first of those brings a deemed planning application with it, and a fee.

Lodging the appeal suspends the notice until it is decided, which is why the deadline on an enforcement notice is the least forgiving one in the system. This is not a form to fill in on your own.

Costs, and why they rarely change hands

Each side pays its own unless somebody has behaved unreasonably.

Costs do not follow the event in a planning appeal. Winning does not entitle you to recover what you spent, and losing does not expose you to the council’s expenses. An award is only made where a party has behaved unreasonably in the process itself, and the classic example is a council refusing an application against its own officer’s advice with no evidence to support the reasons it gave.

The rule runs both ways. An appellant who lodges an appeal with no reasoned case, or who withdraws late after the council has done the work, can have costs awarded against them. Unreasonableness here is about conduct rather than about being wrong.

Appeal, or apply again

The refusal notice usually answers this for you if you read it properly.

Start with the reasons for refusal and the officer’s report behind them. A refusal directed at one element, a depth, a first floor window position, a flat roof where the officer wanted a pitch, is telling you what to change and is an argument for redesigning and resubmitting. A refusal that goes to the principle of extending at all, or that rests on a policy reading you believe is wrong, is what appeals exist for.

Timing cuts the same way. A fresh application starts a new statutory period with a decision maker who can visit and can negotiate. An appeal is measured in months and produces a binary answer from someone who cannot suggest a compromise. The practical detail of resubmission, including where the fee rules bite, is on our planning application support page, and the immediate question of what happens if planning permission is refused is answered separately.

An appeal is also not a soft second opinion. Inspectors apply the same policies as the officers did, and a good proportion of householder appeals are dismissed, so an appeal made because the refusal felt unjust rather than because the case is strong tends to cost several months and confirm the answer.

After the inspector has decided

There is no second appeal.

An inspector’s decision is final on the planning merits. The only challenge available is to the High Court, on a point of law, within a short statutory window and with the court’s permission. Legal error means something like taking an irrelevant consideration into account, failing to give adequate reasons or misinterpreting a policy. Disagreeing with the judgement reached is not a point of law, and the court cannot substitute a different planning answer even where it finds one.

The realistic route after a dismissed appeal is a new application for a materially different scheme, informed by two sets of reasons rather than one. That is more information than most applicants ever get, and it is worth using rather than resenting.

Nobody can promise you a planning outcome at any stage of this, on appeal least of all. What we can do is read the refusal properly, tell you plainly whether the case is about policy or about design, and say when the honest answer is to redraw it rather than to spend three months proving a point.

Appeal procedures, periods and fees are set in regulations that change, and how any of this applies depends on your decision notice and the reasons on it. Treat this as an explanation of how the appeal system works rather than as advice on a particular refusal.
