Appeal procedures compared: written, hearing and inquiry

The Planning Inspectorate decides which procedure your appeal follows, not you. You state a preference on the appeal form, give reasons against the published criteria, and the Inspectorate allocates the case to written representations, a hearing or an inquiry. Householder and minor commercial appeals go to an expedited written procedure with no choice at all.

For everything else, the allocation decision shapes the cost, the programme and the kind of evidence you need, so it is worth arguing for properly rather than ticking a box.

How the procedure is decided

The Inspectorate applies criteria published in its procedural guide for planning appeals in England. The questions it asks are practical ones: whether the issues are complex or raise legal or policy questions needing testing, whether the evidence needs probing through cross-examination, whether there is substantial local interest requiring a public forum, and whether the case can be understood from written material alone.

Scale alone does not decide it. A 400-dwelling appeal with agreed technical evidence and a single policy issue can run on written representations. A householder-scale appeal cannot be escalated to an inquiry however strongly the parties feel, because the expedited procedure applies.

Three factors carry real weight in practice. Whether a party intends to call expert evidence that the other side disputes. Whether the case turns on the credibility or reliability of evidence rather than on its interpretation. And whether a statutory consultee has maintained an objection that needs resolving between witnesses.

The Levelling-up and Regeneration Act 2023 includes provisions allowing appeals to be handled by a combination of procedures, so part of a case could be heard and part dealt with in writing. Check the commencement position and the Inspectorate's current guidance before assuming that route is available on your appeal.

What written representations involve

Written representations is the default and it handles the large majority of planning appeals. The sequence is a statement of case from each main party, then the local planning authority's statement, then an opportunity to comment, then a site visit by the inspector, which may be unaccompanied or accompanied depending on whether the site can be seen from public land.

Its strength is cost and speed. Its weakness is that the inspector reads your case once and cannot ask you a question. Everything has to be on the page.

That changes how you write. A written appeal statement should be structured around the reasons for refusal, deal with each in turn, cross-refer to the document and page where the evidence sits, and avoid rehearsing material the inspector already has. Where the original Planning Statement made the case well, the appeal statement should build on it rather than repeat it, and it should answer the officer report rather than the application.

The commonest failure on written reps is the site visit. If the harm alleged can only be understood from a particular viewpoint, say where that viewpoint is, provide an annotated plan, and request an accompanied visit with reasons.

When a hearing fits

A hearing is a round-table discussion chaired by the inspector. There are no advocates in the formal sense, no evidence-in-chief and no cross-examination. The inspector works through an agenda, asks questions, and lets the parties respond to each other.

It suits a particular kind of case: one where the issues are reasonably contained, where the facts are not seriously in dispute, and where the inspector's understanding would be improved by discussion rather than by testing. Design cases, condition disputes and some change of use appeals sit well in a hearing.

It does not suit a case where you need to dismantle the other side's expert evidence. Without cross-examination, a weak witness is not exposed, and a confident assertion sits unchallenged on the record alongside your careful analysis.

Hearings have become less common than they once were, with cases tending to resolve either into written representations or into inquiries. That is a trend rather than a rule, and a well-reasoned request for a hearing on a contained case still succeeds.

What an inquiry requires of the parties

An inquiry is a formal process and it needs resourcing like litigation.

The parties produce statements of case, then proofs of evidence from each witness with appendices, then a statement of common ground recording what is agreed. There is usually a case management conference, at which the inspector fixes the issues, the timetable, the sitting days and the running order. Advocates examine their own witnesses and cross-examine the other side's. Third parties can appear and be heard.

What that means in practical terms:

1. An advocate, usually counsel, instructed early enough to shape the evidence rather than present it.
2. A witness for each disputed topic, each of whom must be able to give independent expert evidence and withstand cross-examination.
3. A statement of common ground negotiated properly, because every fact agreed is a day you do not spend in the room.
4. A proof of evidence per witness, exchanged to a deadline, which the witness has written and can defend.
5. Someone managing the documents, the core bundle and the conditions schedule.

The conditions schedule is the item most often left to the last minute and it costs appellants real money. Agree draft conditions with the authority before the inquiry opens, with the disputed wording identified, so the inspector is not drafting from scratch at the end.

Where the appeal turns on the weight to be given to a plan under preparation, the evidence has to deal with where that plan has reached, and plan-making reform and what happens to emerging plans affects how that argument is framed.

Timescales for each route

Published timeliness figures move, so take the current position from the Inspectorate's own statistics rather than from a figure quoted in an article. The direction of travel since the Rosewell review of inquiry procedure in 2019 has been towards shorter inquiry timescales through earlier case management and tighter timetabling, with the review setting a target measured in weeks rather than months for the inquiry route.

Two programme points apply whichever route you take. The deadline to lodge is fixed and unforgiving: twelve weeks from the decision for householder and minor commercial appeals, six months for most other planning appeals, and a different and much shorter window for enforcement notice appeals. And an extension of time agreed with the authority before refusal is almost always quicker than an appeal.

Cost and resourcing differences

Written representations costs the appellant the consultant's time in preparing the statement, and little else. An inquiry costs the appellant counsel, witnesses, sitting days, venue contributions in some cases, and the internal time of managing all of it. A hearing sits between the two and is usually closer to the written reps end.

Costs awards are a separate matter from the procedure. An award can be made on any procedure, and the ground is unreasonable behaviour that has caused another party to incur wasted expense, not simply losing. Authorities face costs applications for refusing contrary to clear officer advice without evidence, for failing to produce evidence for a reason for refusal, and for withdrawing a reason at a late stage. Appellants face them for pursuing an appeal that had no prospect or for late amendment of the case.

Resourcing an inquiry badly is worse than choosing written representations. A witness who cannot defend a proof under cross-examination damages the case more than a written statement would have.

Asking for a particular procedure

Use the space on the appeal form properly. Identify the main issues, say which of the published criteria apply and why, and be specific about what the procedure needs to achieve.

A request that works reads like this: the appeal turns on disputed expert evidence about highway capacity and on the interpretation of a development plan policy, two witnesses on each side will give evidence, the authority has confirmed it will call a witness, and cross-examination is needed to test the trip generation assumptions. A request that does not work says the case is important to the appellant.

If the Inspectorate allocates a procedure you did not ask for, you can write and ask it to reconsider, with reasons. Do it immediately. Once the timetable is issued the practical answer is to prepare for the route you have, and a well-prepared written appeal beats a poorly resourced inquiry every time.
