Householder appeal against a full planning appeal

If your extension was refused, you have twelve weeks to appeal, not six months, and you get one shot at putting your case. That is the householder appeal in a sentence. The standard full appeal used for everything else runs to a six-month deadline, allows a fuller exchange of statements, and can be heard at a hearing or an inquiry rather than decided on paper.

Which route you are on is not a choice. It follows from what kind of application was refused.

Which decisions go down each route

The householder appeals service covers appeals against the refusal of planning permission for householder development: extensions, loft conversions, outbuildings, porches, hard standings and similar works within the curtilage of a dwellinghouse, made on the householder application form.

Everything else goes through the standard procedure. That includes a refused application for a new dwelling in your garden, a change of use, anything on a flat, and any application that was made on the full form even though the works felt domestic. It also includes listed building consent refusals, which have their own route and cannot use the expedited service even where the building is your house.

The distinction that catches people out is the flat. Works to a flat are never householder development, so a refused balcony or roof terrace on a flat is a full appeal with six months to lodge it.

The twelve-week deadline

Twelve weeks from the date on the decision notice. Not from when you received it, not from when you opened it.

The Planning Inspectorate has a discretion to accept a late appeal, and it is exercised rarely and on strong grounds. Illness with medical evidence, occasionally. Being busy, never.

The practical consequence is that the decision to appeal has to be made quickly, while you are still annoyed and before you have priced the alternative. Give yourself a fortnight to decide, then a month to prepare, and lodge with a week in hand.

What you can submit, and when

You submit the appeal form, the grounds of appeal, the application drawings and documents, and any supporting statement, all at once. The council supplies its officer report, the decision notice and the representations it received on the application. The inspector reads that bundle, visits the site, and decides.

There is no second round. The council does not write a fresh statement attacking your case, and you do not get to answer one. That symmetry is the point of the service, and it works in the applicant's favour more often than people expect, because the council's case is fixed at whatever its officer wrote.

Which means your appeal statement must do all the work at once. It has to explain the proposal, deal with each reason for refusal, engage with the neighbours' objections that were made on the application, and set out any changes to policy since the decision.

No second chance to add evidence

The trap is straightforward. If the officer report says the extension would be "overbearing when viewed from the rear garden of number 14", and you did not include a photograph or a sectional drawing from that garden, you cannot add one later.

So build the evidence into the submission:

• Photographs from the viewpoints named in the reasons for refusal, not from the angles that flatter the scheme.
• A section showing the 45-degree line from the neighbouring window where daylight or overbearing impact is alleged.
• A street scene elevation where character and appearance is a reason.
• Examples of similar development already approved in the street, with application references so the inspector can look them up.

That last one is worth doing properly. Inspectors take consistency seriously, and an approved dormer three doors down with the same proportions is a stronger argument than three paragraphs about design.

Amended drawings are not usually accepted either. The appeal is against the refusal of the scheme as submitted, so a redesign belongs in a fresh application rather than in an appeal.

When the standard route is worth the wait

You do not get to choose, but the distinction matters if your project can be reshaped.

A full appeal allows a hearing, where an inspector, the applicant and the council discuss the issues around a table, and that format suits cases turning on a judgement about character or on a factual dispute about, say, existing use. It also allows costs applications where a council has behaved unreasonably, for instance by refusing contrary to its own officer's recommendation without evidence.

If your scheme is borderline householder development and you would benefit from that fuller process, the way in is to apply on the full form in the first place. That is a decision made months before any refusal, and it is one an agent should be raising with you at the outset.

The free resubmission most people forget

Before appealing, check whether a revised application is the better move.

The fee regulations allow one further application on the same site by the same applicant, for development of the same character or description, without a fee, within twelve months of the decision on the earlier application. That gives you a route to address the reasons for refusal directly, with the same officer, in eight weeks rather than several months.

Appeal where the council is wrong. Resubmit where the council is right about something you can fix. A refusal citing a rear extension depth of four metres against a three-metre guideline is usually a resubmission. A refusal citing harm to the character of the area on a scheme that matches three neighbours is usually an appeal.

You cannot do both at once on the same scheme, so decide which before the twelve weeks runs.

Writing the grounds of appeal

Structure the statement around the reasons for refusal, one heading each, in the council's own order. Quote the reason, then answer it.

Answer with the development plan first. Name the policy, quote the part that matters, and show how the proposal complies. Then deal with the supplementary planning guidance the officer relied on, which in householder cases is usually a design guide with numerical thresholds. Then the material considerations: the pattern of similar approvals, the absence of objection from a technical consultee, any change in national policy since the decision.

Keep it short. A householder appeal statement that runs beyond ten pages is usually repeating itself, and inspectors read hundreds of these.

The same discipline applies to the original application, where a well-organised Planning Statement and, where design is contentious, a Design and Access Statement often prevent the refusal in the first place.
