Written representations, hearing or inquiry: choosing
The Inspectorate decides the appeal procedure, not the appellant. What each route involves, when cross-examination earns its cost, and how to ask for a different one.
The Planning Inspectorate decides which planning appeal procedure applies, not the appellant. You state a preference on the appeal form and give reasons, and the Inspectorate tests that against published criteria about the complexity of the issues and whether the evidence needs to be tested in person. Written representations handle the large majority of appeals. Hearings and inquiries exist for the cases where writing alone cannot resolve what is in dispute.
Choosing the preference well matters, because the wrong procedure costs either money you did not need to spend or the chance to test evidence you needed to test.
What each procedure involves
Written representations run entirely on paper. The appellant submits a statement of case, the authority submits its statement, interested parties comment, and the inspector visits the site, either unaccompanied or with the parties present but silent on planning merits. Householder appeals use a shortened version with no further statements beyond the original application and appeal documents.
A hearing is a round-table discussion led by the inspector, held in a council chamber or hired room. There are no advocates in the usual sense and no cross-examination. The inspector works through an agenda, asks questions of each party, and takes the discussion where the issues require. Most hearings last a day.
An inquiry is a formal proceeding. Advocates appear for the main parties, expert witnesses give evidence in chief and are cross-examined, proofs of evidence are exchanged in advance, and a statement of common ground narrows what is actually in dispute. Inquiries run from two days to several weeks.
The decision itself is identical in status whichever route is used. The difference is entirely in how the evidence reaches the inspector.
How the Inspectorate decides the route
The published criteria look at the nature of the issues rather than the size of the scheme.
Written representations suit appeals where the issues are clear from the documents, where the evidence is essentially documentary, and where nothing turns on the credibility of a witness. Most householder, minor residential and change of use appeals sit here.
A hearing suits cases where the inspector needs to ask questions to understand the evidence, where the issues are not legally complex, and where the parties are unlikely to be represented by advocates. Small scale viability, personal circumstances, agricultural need and condition disputes often come here.
An inquiry suits cases where evidence needs formal testing by cross-examination, where the issues are legally or technically complex, where there is substantial local interest, or where a major scheme carries a wide policy dispute such as housing land supply, Green Belt very special circumstances or heritage balance.
If your preference does not match those criteria, explain in the appeal form why the case is different. The Inspectorate does change procedure where the reasoning is good, and it can also change it later if the issues develop.
Cost and time compared
| Procedure | Typical duration | Main cost drivers |
|---|---|---|
| Written representations | Shortest of the three | Preparing the statement of case; no advocacy |
| Hearing | Longer than written representations | One day of attendance, consultant time, occasionally a solicitor |
| Inquiry | Longest, often by several months | Advocate fees, proofs of evidence, expert witnesses, venue and sitting days |
Published timescales change as the Inspectorate's caseload changes, so check the current performance figures before you programme a scheme around an appeal date rather than relying on a rule of thumb.
The cost gap between a hearing and an inquiry is wide. An inquiry on a major scheme brings a barrister, several expert witnesses producing proofs and rebuttals, and a room for a week. That is a decision to take with a funder rather than in isolation.
When cross-examination earns its cost
Cross-examination is worth paying for when a decisive part of the council's case rests on a judgement that can be shown to be unsupported.
The classic examples are housing land supply, where the arithmetic and the assumptions behind a five-year position can be dismantled point by point, and viability, where a benchmark land value or a build cost assumption falls apart under questioning. Highway safety cases where the authority relies on an accident record, and heritage cases turning on the degree of harm, also benefit from testing.
Where the dispute is about design quality, or about whether an extension is too big, cross-examination adds very little. Two experienced professionals disagreeing about visual impact do not become more persuasive under questioning; the inspector will form their own view on the site visit.
There is a costs dimension too. At an inquiry, an application for costs against a party that behaved unreasonably is a live prospect, and unreasonable behaviour includes defending a refusal reason with no evidence. That risk changes how councils prepare.
Matching the evidence to the route
Some evidence types survive the written process well and some do not.
Documentary evidence, policy analysis, drawings and technical assessments read perfectly well on paper. A Planning Statement that sets out the policy case in a structured way does most of the work in a written representations appeal, and the statement of case can then focus on the refusal reasons.
Evidence that depends on assumptions, judgement and method benefits from a forum where it can be explored. A Viability Assessment is the clearest example, because the numbers are only as good as the inputs and the inputs are contestable.
Evidence about how a place feels usually resolves on the site visit whatever the procedure, which is a reason to think hard before paying for an inquiry on a design-led refusal.
For any route, the statement of case should track the refusal reasons in order and deal with each one on its own terms. Inspectors read a great many of these, and a document that answers a different question than the one the council asked is easy to spot.
Asking for a different procedure
Both the appellant and the local planning authority express a preference on the relevant form. The Inspectorate then determines the procedure and notifies the parties, and it will explain the choice if asked.
If you disagree, write promptly with reasons tied to the published criteria rather than to convenience. Arguments that work include a legal issue requiring submissions, a factual dispute where a witness's evidence needs testing, and substantial third party interest requiring a public forum. Arguments that do not work include a preference for speaking rather than writing.
Procedure can also change during the appeal. A case that starts as written representations can be converted where the issues turn out to be more complicated than the papers suggested, so a well argued request part way through is not wasted.
Decide the route at the same time as you decide whether to appeal at all, because it changes the budget by an order of magnitude and it changes who you need to appoint. Browse the report types that will underpin the appeal evidence before committing to a date.

Frequently asked questions
Can I choose my planning appeal procedure?
You state a preference with reasons on the appeal form, and the Planning Inspectorate decides. It applies published criteria about the complexity of the issues, whether evidence needs testing in person and the level of public interest. Householder appeals always run on written representations. A well argued request tied to those criteria does sometimes change the outcome.
What happens at a planning hearing?
A round-table discussion led by the inspector, usually lasting a day, with no advocates and no cross-examination. The inspector works through an agenda and asks questions of each party in turn, then visits the site. It suits cases where the inspector needs to understand evidence by asking about it rather than by having it tested adversarially.
When is a planning inquiry worth the cost?
When a decisive part of the council's case rests on a judgement that can be shown to be unsupported. Housing land supply arithmetic, viability inputs, accident-based highway safety cases and heritage harm all reward cross-examination. Design quality disputes rarely do, because the inspector forms their own view on the site visit whatever the procedure.
Can the appeal procedure change once it has started?
Yes. The Inspectorate can change the procedure where the issues turn out to be more complex or simpler than the papers suggested, and either party can ask. Write promptly with reasons tied to the published criteria rather than to convenience, because a request based on preference alone will not succeed.
Are costs recoverable at appeal?
Costs applications are available where a party has behaved unreasonably and caused another to incur wasted expense, and they are most commonly made at inquiries and hearings. Defending a refusal reason with no supporting evidence is a recognised example of unreasonable behaviour. Householder appeals operate under a narrower regime, so check the current guidance before relying on a costs claim.
