Householder appeals and the twelve week procedure

If your householder application was refused, the appeal has to reach the Planning Inspectorate within 12 weeks of the date on the decision notice. That is the number to write in your diary, because it is half the six months allowed for most other planning appeals and the Inspectorate has no power to accept a late householder appeal. Miss it and your only route back is a fresh application.

The householder appeals procedure is deliberately stripped down. One combined form, no separate statement of case, no new evidence from either side, and a decision on the papers after an unaccompanied site visit. That design is what makes it quick. It is also what makes it unforgiving if the case you needed to make depends on something the council never saw.

Which decisions qualify

The procedure applies to appeals against the refusal of a householder application, or against conditions imposed on one. Householder development means work to a house or within its curtilage: extensions, loft conversions, dormers, porches, outbuildings, garden rooms, hardstanding, dropped kerbs, boundary walls and fences.

Several things fall outside it. Listed building consent appeals go down the ordinary route. So do appeals about anything involving a change of use, applications relating to flats rather than houses, advertisement consent appeals and appeals concerning development subject to environmental impact assessment. An enforcement appeal is an entirely different procedure with its own grounds and its own form.

If your application was a householder application on the standard form and was refused on planning grounds, you are very likely in the householder procedure. Where there is any doubt, the Planning Inspectorate's procedural guidance says which route applies, and putting an appeal in under the wrong procedure wastes weeks.

The twelve week deadline and what it means

Twelve weeks runs from the date of the decision notice, not from the date you received it and not from the date of the committee meeting. Count it out on a calendar the day the notice arrives.

There is no discretion to extend. Unlike the six-month window for other appeals, the householder deadline is applied strictly, and an appeal submitted on week thirteen is returned as invalid. Submit through the online appeals casework portal rather than by post, so you have a timestamped receipt.

Once the appeal is valid the Inspectorate issues a start date and the timetable runs from there. The council sends its questionnaire and the case papers, the inspector visits the site, and the decision follows. Expect the whole process to take a few months from start date to decision, and treat any published target as an objective rather than a promise.

Why no new evidence is allowed

This is the rule that catches people. In a householder appeal, the inspector decides on the material that was before the council when it made its decision. Neither you nor the council may introduce anything new.

So no revised drawings. No new daylight study, no structural report, no arboricultural assessment, no additional photographs of comparable extensions three streets away, unless all of it was submitted with the application. Anything new is returned or disregarded.

The restriction is symmetrical, and that is its one advantage to an appellant. A council that refused on a ground it never evidenced cannot fix the gap at appeal stage. If the reason for refusal asserts harm to the character of the area and the officer report contains nothing beyond that assertion, the inspector has nothing to weigh against your case.

Two consequences for how you handle the application stage. Put the full case in at the start, including the policy analysis and any technical material, because you cannot add it later. And where the officer asks for further information during determination, supply it rather than letting the application be refused on an incomplete file. Our note on material considerations and what the law allows sets out which arguments can carry weight in the first place.

What to put on the appeal form

The householder form combines the appeal and the grounds, so the box asking why you disagree with the decision is your whole case. Around 1,000 to 2,000 words is usually enough, and it should be structured rather than aggrieved.

1. Set out the proposal in two or three sentences, with the drawing numbers.
2. Take each reason for refusal in turn, quote it, and answer it.
3. For each one, identify the development plan policy the council relied on, quote the part of the policy that matters, and explain why the proposal complies with it. The statutory starting point is the development plan, as our explainer on section 38(6) and the development plan sets out.
4. Point to anything already on the file that supports you: the officer report where it accepts part of your case, consultee responses, the absence of objection from the highway authority, existing similar development visible in submitted photographs.
5. Address the harm the council identified directly rather than arguing that the benefits outweigh it. On a householder case, showing there is no harm is a stronger position than balancing.
6. Say what conditions you would accept. Inspectors often allow appeals subject to conditions, and offering sensible ones removes a reason to dismiss.

Attach the documents the form asks for: the application form, the decision notice, the approved drawing set as submitted, the officer report and the site location plan. Nothing else.

The site visit and third party comments

Most householder site visits are unaccompanied. The inspector views the site from public land, takes photographs and leaves. If the proposal cannot be understood without going inside or into the garden, the visit is accompanied, and you will be told in advance.

At an accompanied visit the inspector will not discuss the merits. They will look at what you point out physically, such as a boundary level or a window position, and they will decline to hear argument. Do not take that as hostility. The case is decided on the papers, and anything said at the visit that is not on the file cannot be taken into account.

Neighbours who commented on the application have their original representations forwarded to the inspector as part of the case papers. In the householder procedure they are not invited to comment again. Someone who objected at application stage does not get a second bite, and nor do you.

Outcomes and what happens next

Three outcomes are possible. The appeal is allowed, which grants permission, usually subject to conditions the inspector imposes. It is dismissed. Or it is allowed in part, which happens most often where the appeal was against conditions rather than against refusal, and the inspector varies or deletes one.

The decision is final on the planning merits. The only challenge is a statutory application to the High Court under section 288 of the Town and Country Planning Act 1990, within six weeks, and only on a point of law. Disagreeing with the inspector's planning judgement is not a point of law.

Costs can be awarded in a householder appeal, but only where a party behaved unreasonably and that behaviour caused wasted expense. Losing does not qualify. Because the procedure bars new evidence and runs to a fixed timetable, there are fewer of the procedural failures that generate awards elsewhere.

Choosing between an appeal and a resubmission

The honest test is whether your scheme needs to change.

Appeal where the scheme is right, the evidence is already on the file, and the refusal turns on a policy judgement you think is wrong. Appeal also where the reason for refusal is thin or unevidenced, because the no-new-evidence rule stops the council improving on it.

Resubmit where the scheme needs amending, where you want to add a survey or a report, or where the officer told you what would be acceptable and you can live with it. The fee regulations allow one further application on the same site for development of the same character without a further fee, within a set period after the earlier decision, subject to conditions. Check the current fee schedule and confirm your eligibility with the council before assuming it applies.

You can do both. Submit the revised application and lodge the appeal on the original, so the 12-week deadline does not expire while the new application is being determined. It costs an extra fee and it keeps both options open, which on a contested householder case is often worth it.

Where the refusal rested on policy grounds, a properly argued planning statement with the revised application is usually what changes the officer's recommendation second time round, and the full index of report types shows what else a site with constraints may need.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it. To see which documents your site is likely to need before you resubmit, enter your postcode on PlanScope.
