The householder appeal service and what it does not allow

The householder planning appeal process is fast because it is narrow. You have twelve weeks from the date on your refusal notice to lodge the appeal, the Planning Inspectorate decides it on the papers that were already before the council plus your grounds of appeal, and once you have submitted it you cannot add anything. No new survey, no revised drawing, no further letter. For a householder refused a rear extension, that trade is often the wrong one, and a second application is frequently the better move.

Which refusals qualify for the householder route

The service covers refusals of householder planning applications. That means development within the curtilage of a house for purposes incidental to its enjoyment, and extensions or alterations to a house.

Typical qualifying refusals include a rear or side extension, a loft conversion with a dormer, a garage conversion, a garden room, an outbuilding, a porch, a dropped kerb and vehicular access, and a boundary wall or fence.

The route is not available where the proposal does anything more than that. Creating a new dwelling takes it outside, as does any change of use, work to a flat, a listed building consent appeal, an advertisement consent appeal, or development requiring environmental impact assessment. If your application was for two dwellings or for a house in multiple occupation, you are in the ordinary appeal system with its six month deadline and its full exchange of statements.

Appeals against a condition on a householder permission can usually use the service as well. Check the appeal form, because the Inspectorate will reject an appeal lodged under the wrong procedure and the clock keeps running while you work out which one applies.

The twelve week deadline, and why it is absolute

Twelve weeks from the date of the decision notice. Not from the date you received it, not from the date you read it.

The Inspectorate has no discretion to accept a late householder appeal. This is the single most common way householders lose a case they would have won, and it happens because the refusal arrives, the family talks about it for a month, an architect is consulted, a quote is obtained, and the deadline passes in week thirteen.

Diarise the date the day the notice arrives. Then decide, within the first fortnight, whether you are appealing or reapplying, because the two routes need different work.

What you may submit, and what you may not

Everything goes in at once. The appeal form, your grounds of appeal, and any supporting material you want the inspector to see, all submitted together.

After that the exchange is closed. The council does not prepare a statement, because it relies on its decision notice and its officer report. You get no opportunity to respond to anything. Neighbours do not comment again, although the representations they made at application stage are passed to the inspector.

The practical consequences are worth spelling out.

• You cannot introduce a daylight study, an arboricultural report or a highway drawing that was not part of the application, so if the refusal reason turns on evidence you never supplied, the appeal is the wrong route
• You cannot amend the scheme. The inspector determines the application as refused, not a smaller version of it
• You cannot answer a point the council makes for the first time in its officer report, except within the grounds you submit at the outset
• You can include photographs, dimensions taken from the approved drawings and references to policies and to other decisions, because those are argument rather than new evidence

Why the appeal is decided on the application material

The design of the service assumes the council had everything it needed and reached a decision you disagree with. The inspector is being asked to form a different planning judgement on the same facts.

That makes the householder appeal strong on matters of judgement and weak on matters of fact. A refusal that says the extension would be out of keeping with the character of the area is a judgement, and a well argued appeal can overturn it. A refusal that says insufficient information has been submitted to assess the impact on the neighbouring window is a factual gap, and you cannot fill it.

Read your refusal reasons with that distinction in mind before choosing a route. Where the reasons are mixed, the usual answer is a fresh application that cures the evidence gap, followed by an appeal later if the judgement point survives.

Appeal decisions from comparable cases are argument rather than evidence, so they can be cited, and our note on using appeal decisions in a planning application explains how to find and present them without overstating what they prove.

Site visits and how they are carried out

The inspector visits the site. Most householder visits are unaccompanied, carried out from the highway or from land the inspector can see the site from, without the parties present.

An accompanied visit is arranged where the inspector needs to go inside a property or onto private land, for example to look at the outlook from a neighbour's window. You will be told in advance, and the visit is not a hearing. Nobody argues the case on site, and an inspector who is offered an argument at an accompanied visit will decline it.

Two practical points. Make sure the site is accessible and that any locked gate is dealt with. And if the appeal turns on something only visible from a particular position, say so in your grounds and explain where that position is, because the inspector cannot read your mind from the pavement.

When a fresh application beats an appeal

Most householders do better with a second application, for three reasons.

The first is the free go. Where you submit a further application for development of the same character or description on the same site within twelve months of the refusal, the fee regulations allow one application without a further fee, subject to the conditions in the regulations. Check the current position with your council, because the rules and the figures are reviewed periodically.

The second is that you can change the design. A rear extension refused at 4 m deep can be resubmitted at 3 m. An appeal cannot do that.

The third is speed and relationship. A revised householder application has an eight week target and goes back to the same officer, who has told you in a published report exactly what the problem was. Appeals take longer than that.

Appeal where the council has misapplied its own policy, where the refusal is inconsistent with a nearby permission you can point to, where the objection was really about a neighbour dispute, or where you cannot reduce the scheme without losing the point of it. Our note on highway safety refusals and visibility splay evidence covers one category where the evidence position usually decides which route to take.

Writing the grounds of appeal

The grounds are the only document you control, so structure them against the refusal.

1. State the proposal in one short paragraph and identify the application reference and the refusal date.
2. Take each refusal reason in turn, quote it, and answer it. Do not answer them collectively.
3. For each reason, name the local plan policy relied on, set out what the policy actually requires, and show by reference to the drawings and dimensions why the proposal meets it.
4. Address the neighbour representations that the officer report records, briefly, where they go to a planning matter.
5. Say what weight you say the inspector should give to any comparable permissions nearby, with application references.
6. Finish with the planning balance in your own words, in four or five sentences.

Keep it short. A clear eight page statement beats a forty page one, and inspectors read every householder appeal themselves.

A well written Planning Statement from the original application does much of this work already, and where the refusal is about design and character, the reasoning in a Design and Access Statement is the material the grounds should build on.
