Hearings and inquiries compared with written appeals

Lodging a planning appeal costs nothing. The Planning Inspectorate charges no fee for any of its three procedures, so the whole cost of a planning inquiry sits in professional time, venue and the months the scheme is not being built. That is why the procedural choice matters commercially: a written representations appeal on a small scheme might be handled by one planner, while an inquiry on a major residential refusal pulls in a barrister, several expert witnesses and a programme officer.

The three procedures and who chooses

Appeals proceed by written representations, by hearing or by inquiry. You state a preference and give reasons on the appeal form. The Inspectorate decides.

It applies published criteria rather than a formula. Complexity of the issues, whether the evidence needs testing by cross-examination, the amount of public interest, and whether legal submissions are likely all count. A refusal turning on one amenity judgement will stay in writing. A refusal turning on housing land supply, viability and heritage balance will not.

You are not powerless here. A short, specific case on the form, naming the issues that require cross-examination and the witnesses who would give evidence, carries more weight than a bare request for an inquiry.

What each procedure involves

A hearing is often underused. It gives you the chance to answer the inspector's questions directly without the cost of formal evidence, and for cases where the disagreement is technical rather than adversarial it is frequently the right middle route.

Where the money goes

Cost on an appeal is almost entirely the cost of evidence and advocacy. There are four drivers worth separating when you build the budget.

The number of disputed issues comes first, because each one needs a witness or a section of statement, and each brings its own rebuttal. Then the depth of technical work, since an issue like viability or transport modelling can consume more fee than everything else put together. Third, advocacy, which applies only to inquiries in practice. Fourth, the internal time nobody costs, which for a developer means the project manager and the land team.

New survey work commissioned specifically for the appeal sits outside those four and is often the biggest single line. If you can avoid it by putting the evidence in with the original application, do. Budgeting an application pack properly at the start, and knowing what PlanScope pricing covers for the supporting statements, is a good deal less painful than paying for the same documents twice under appeal pressure.

Timescales and the commercial consequence

Written representations is the fastest route and inquiries the slowest, with hearings between. The Inspectorate publishes current average timescales by procedure on gov.uk, and those figures move, so check them rather than relying on a number from a past scheme.

For a developer the tail matters more than the average. An inquiry adds listing risk, because a venue, an inspector and several diaries have to coincide, and a slipped date moves everything with it. If the site is held on an option with a fixed expiry, or the scheme's funding assumes a start on site in a given quarter, that tail risk is the number to model.

There is a related point about holding costs. Land holding, professional retainers and, on a commercial site, empty rates continue throughout. On a scheme of any size those exceed the appeal fees comfortably.

One more timing trap catches developers who have chosen the wrong route. If the Inspectorate directs an inquiry when you budgeted for written representations, the programme lengthens and the fee position changes at the same moment, with witnesses to appoint from a standing start. Asking for the procedure you can actually resource, and saying so plainly on the form, avoids being escalated into a process you have not staffed.

When an inquiry is unavoidable

Some appeals cannot sensibly go any other way.

Cases where the council's evidence must be tested by cross-examination, typically a disputed five-year housing land supply position or a contested viability appraisal. Cases turning on the interpretation of a statutory provision or a policy where legal submissions are needed. Green Belt cases where very special circumstances are argued and the balance depends on weighing several factors. Heritage cases where the level of harm is disputed by qualified witnesses on both sides. Enforcement appeals where the facts of use and its duration are contested by evidence from neighbours.

If your appeal is on that list, budget for an inquiry from the outset rather than hoping for a hearing. Appointing witnesses late is the most reliable way to overspend.

Preparing evidence for each route

The written material is not the same document at three lengths.

For written representations, your statement is the whole case. It has to be self-contained, cross-referenced to the plans and policies, and readable by an inspector who will see the site briefly. For a hearing, prepare a statement plus a short note of the points you want to discuss, because the format rewards a witness who can answer directly rather than read aloud. For an inquiry, the proof of evidence must be capable of standing up to cross-examination, which means every assertion needs a source and every number needs a working.

The council's case tells you where to spend. Read the appeal questionnaire and the council's statement carefully, because authorities often defend less than their reasons for refusal implied, and you may be able to drop a witness.

Making the procedural case on the appeal form

1. List the disputed issues as short propositions rather than themes.
2. For each, say whether it can be resolved on paper, by discussion, or only by cross-examination, and why.
3. Name the witnesses you would call and their disciplines.
4. Say whether legal submissions are likely and on what point.
5. Give an estimate of the sitting days required if you are asking for an inquiry.
6. State any date constraints, such as a witness unavailable in a particular month.

Before any of that, confirm the appeal is the right move at all. Where the refusal could be answered by a modest redesign, resubmitting under the free go concession costs no fee and usually resolves faster than an appeal. And if the council has behaved unreasonably, note that costs awards at appeal are available in both directions, which is a reason to keep your own conduct clean.

Whichever procedure you end up in, the document doing the heaviest lifting is the planning case itself. Drafting that early, alongside the rest of the evidence base, is why it is worth knowing which of the 66 report types your appeal actually needs before the timetable starts.
