How a householder appeal was won on a single point

A householder appeal won on a single point usually looks like this from the outside: one refusal reason, one drawing, one paragraph in the inspector's decision. From the inside it is a decision about scope. The householder appeal service is expedited, you get one statement and no chance to answer the council's case, so the discipline is to pick the argument you can win and leave everything else out.

The deadline is 12 weeks from the date on the decision notice, not six months. Miss it and the only route left is a fresh application.

The refusal and the reasons given

Illustrative example: a single storey rear extension on a 1930s semi, 4 metres deep, refused on one ground. Loss of daylight to the neighbour's kitchen window, contrary to the council's householder design guide and its 45 degree test.

Read a refusal like this twice. The first read tells you what the officer decided. The second tells you what the officer relied on, which is the only thing you can challenge. Here the guide applied a 45 degree line in plan from the centre of the neighbour's window, and the officer's report said the extension broke it.

It did break it, by about 300 millimetres. That was the whole case.

Deciding whether to appeal or resubmit

There is a free resubmission. Where the original application was granted or refused and not withdrawn, one further application for the same development on the same site by the same applicant within 12 months carries no fee. So the choice turns on whether a revised scheme would be acceptable and whether you want it.

Three rules of thumb settle most cases.

• Two or more refusal reasons that are all matters of fact or compliance: revise and resubmit. The council is telling you what to change.
• One refusal reason that turns on planning judgement, where you think the officer applied a local guideline too rigidly: appeal.
• A refusal reason based on policy you think is misapplied, with the scheme otherwise supported: appeal, and expect to win or lose on that single issue.

Here the alternative was cutting the extension to 3.7 metres, which lost the kitchen island the whole project was for. Appealing kept the scheme intact and risked 12 weeks.

The householder appeal procedure and its timescale

The householder appeal service is deliberately stripped back.

1. Appeal within 12 weeks of the decision notice date, online through the Planning Inspectorate's appeal service.
2. Submit the appeal form, the decision notice, the application drawings and your statement of case at the same time. There is no later opportunity.
3. The council returns a questionnaire and forwards the representations it received on the application. It does not write a new statement.
4. You cannot reply to the questionnaire. Neither side gets a second bite.
5. An inspector usually visits the site unaccompanied, unless access to a neighbour's property is needed.
6. The decision is issued in writing and is final, subject only to a statutory review in the High Court under section 288 of the Town and Country Planning Act 1990 within six weeks.

Timeliness varies with caseload. The Inspectorate publishes current figures for each appeal type, so check those rather than relying on what a neighbour experienced two years ago.

One constraint matters more than any other. You are appealing the scheme as refused. An inspector can accept minor amendments only within narrow limits, so the appeal is not an opportunity to submit an improved design.

Building the case around one issue

Everything in the statement should serve the single point. Write the conclusion first, then work backwards to the evidence.

The structure that works is short: the refusal reason quoted in full, the policy or guidance relied on quoted in full, what the guidance actually says and how it is expressed, the physical facts of the relationship, and the effect on the neighbour assessed properly rather than by rule of thumb.

The argument in the illustrative case was not that the 45 degree line was met. It was that the guide describes the line as an indicator that further assessment is needed, not as a standard that determines the outcome, and that a proper daylight assessment showed the kitchen retained adequate light.

Resist the urge to add material. A statement that also argues about precedent in the street, the neighbour's motives, the officer's tone and the value of the property dilutes the one paragraph the inspector needs.

Evidence submitted with the appeal

Four documents, nothing else.

A section through the relationship between the extension and the neighbour's window, drawn to scale with dimensions and the existing ground levels marked. A plan showing the 45 degree line as the guide describes it, with the geometry annotated. A daylight assessment using the vertical sky component method from the Building Research Establishment guidance, showing the value at the centre of the affected window before and after. And two photographs of the existing condition, taken from inside the neighbour's kitchen if access was given, or from the boundary if not.

The daylight calculation was the document that decided it. A 45 degree test is a screening device. A vertical sky component calculation is a measurement, and where the measurement shows the window comfortably above the guideline value, the screening device has done its job and can be set aside.

Where the scheme also needs supporting narrative, keep it proportionate. The PlanScope report types include the statements a householder appeal might draw on, and for most single-issue appeals the statement of case and the drawings are the whole submission.

The inspector's decision and reasoning

The decision ran to five pages and the reasoning to two paragraphs. The inspector identified the main issue as the effect on the living conditions of the occupiers of the adjoining property with particular reference to daylight, found that the 45 degree indicator was breached, accepted the vertical sky component evidence, and concluded that the actual effect fell short of material harm.

Appeal allowed, with three conditions: standard time limit, development in accordance with the approved plans, and matching materials.

Two things are worth noting about that. The inspector agreed the guidance was breached and still allowed the appeal, which is the normal outcome when an indicator conflicts with a measurement. And the decision is indicative of how inspectors approach the issue rather than a precedent, so it cannot be cited as binding on the next case.

What the outcome cost in time

Fourteen weeks from decision notice to appeal decision, of which two were spent preparing and twelve waiting. The daylight assessment was the only professional cost. No fee is payable to appeal.

Against that, a resubmission would have taken eight weeks and produced a smaller extension. The comparison is not cost against cost. It is time against the scheme you actually wanted.

Where the council has already formed a view and enforcement is in play the calculation is different again, as a retrospective application after enforcement action shows, and a case that turns on a policy principle rather than a measurement needs a different kind of evidence, as a green belt stables appeal does.
