Budgeting a planning appeal as a small developer

A planning appeal cost budget has four lines: your own time, professional fees, the cost of the delay, and the small but real risk of a costs award against you. There is no fee payable to the Planning Inspectorate for a planning appeal in England, which surprises people, although powers to charge have been discussed and the position is worth checking before you plan around it. So the money goes on evidence and advocacy, and how much of each you need depends almost entirely on which procedure the appeal follows.

For a small developer, the decision is rarely whether the case is arguable. It is whether the arguable case is worth what it costs to run.

What each procedure involves

Three procedures exist and they differ by an order of magnitude in cost.

Written representations is the default for smaller cases. Everything is on paper: your appeal statement, the council's statement, third party comments, and a site visit by the inspector. No hearing, no advocacy, no witnesses. For householder refusals there is an expedited version in which the inspector works from the material already before the council and no further representations are invited, which makes the preparation cost lower again.

A hearing is a structured discussion led by the inspector, with no cross-examination and usually no barrister. You or your consultant speak, the council speaks, and the inspector asks questions. It suits cases where the issues are factual and would benefit from being talked through.

An inquiry is formal, adversarial and expensive. Evidence is given by witnesses, advocates cross-examine, and proofs of evidence are exchanged in advance with summaries for anything over 1,500 words. Counsel, a solicitor and one or more expert witnesses are the norm.

The Inspectorate decides the procedure, using published criteria, although the parties can express a preference. For a one or two dwelling scheme, written representations is almost always the answer.

Consultant and legal fee drivers

Three variables drive the figure more than the procedure label.

How many reasons for refusal there are. Each reason needs an answer, and a technical reason needs a technical author. A single design refusal is a planning submission. A refusal citing highways, drainage and ecology is three specialists plus co-ordination.

Whether the evidence already exists. An appeal that reuses reports commissioned for the application costs a fraction of one that needs new surveys, and if a survey has to wait for a season, the programme cost dwarfs the fee.

Who writes it. Consultant quotes for a written planning case on a small scheme commonly sit in a similar range to a full Planning Statement commission, which for a small residential scheme is often somewhere between £500 and £2,500 depending on the constraints. An inquiry with counsel and two expert witnesses is a different category of spend entirely.

Where costs escalate unexpectedly

Four things blow small appeal budgets.

The council raises a new point in its statement that was not in the refusal notice. You then have to answer it, and the answer may need an author you had not budgeted for.

A third party instructs a professional. An organised objector group with a consultant turns a simple case into a contested one, and their material has to be addressed.

The procedure changes. A case you budgeted as written representations gets set down for a hearing, or the council asks for an inquiry, and your preparation has to be rebuilt.

Or the appeal succeeds with conditions you cannot live with. Correcting a condition afterwards means a section 73 application to the council, with its own fee and its own eight or thirteen weeks, which is why offering a draft condition schedule during the appeal is worth the hour it takes.

Cost of delay against cost of appeal

This is the calculation people skip, and for a small developer it usually decides the question.

Work out the monthly carrying cost of the site: finance or the opportunity cost of the capital, any ground rent or rates, insurance, and site security. Then work out the likely appeal timescale for your procedure. The Inspectorate publishes statistics on how long appeals are taking, and the current figures are the ones to use rather than a remembered rule of thumb.

Multiply the two, add the professional fees, and compare the total against the cost of a resubmission with a revised scheme, plus the months that would take.

Two further items belong in the delay column. Build cost movement over the period, which on a small scheme can exceed the appeal fees. And whether any consent or survey expires in the meantime, because a lapsed ecology survey can add a season on its own.

Reading the refusal notice properly is the first step in either direction, and the method for turning refusal reasons into a plan is set out in reading a refusal notice and turning it into a plan.

Exposure to a costs award

Costs at appeal are not awarded because you lost. They are awarded where a party has behaved unreasonably and put the other to expense that need not have been incurred.

Examples of unreasonable behaviour on an appellant's side include pursuing an appeal with no reasonable prospect, withdrawing at the last minute after the council has prepared, failing to provide information that was asked for, and introducing new material so late that the council cannot respond. Councils face applications too, most often for failing to substantiate a reason for refusal or for relying on a policy that does not say what they claimed.

In householder appeals, costs applications are rarely entertained. On larger cases the exposure is real and should sit in the budget as a risk rather than a line item.

The practical protection is procedural discipline: meet every deadline, answer every question asked, and do not withdraw late.

Where a resubmission is the better spend

Often it is, and the fee regulations help. Where an application is refused, a further application for substantially the same development on the same site by the same applicant, made within twelve months, can normally be submitted without a further fee, subject to the conditions in the fee regulations. That is a meaningful saving and it is one reason a revised scheme frequently costs less overall.

Resubmit where the refusal identifies a fixable design problem, where the officer indicated what would be acceptable, or where the committee refused against an officer recommendation to approve and a modest change would give the committee cover to reconsider.

Appeal where the refusal is about a matter of principle you cannot design around, where the council's reasoning misapplies policy, or where the officer recommended refusal on a basis you think is simply wrong. Appeal also where a resubmission would face the same decision maker with the same view.

Withdrawing before a decision is a third option with its own consequences, covered in withdrawing an application before refusal.

Building a simple appeal budget

• Procedure, with the reason you expect it
• Appeal statement or proofs: author, days, rate
• Technical input per reason for refusal, named author and scope
• Drawings and any revised plans
• Advocacy, where a hearing or inquiry applies
• Attendance time at any site visit, hearing or inquiry
• Monthly carrying cost multiplied by expected duration
• Build cost movement over that period
• Survey refresh risk, with the season noted
• Contingency for a new point raised by the council
• Costs award risk, noted as a risk with a view on likelihood

Illustrative example: a refusal of two dwellings on a garden plot, on design and highway safety grounds. The appellant budgets a written representations appeal: a planning consultant's appeal statement, a short highways note from the engineer who did the original access drawing, no new surveys, and the inspector's site visit. Against that sits a resubmission with a reduced ridge height under the fee exemption, which would cost drawing revisions and three months. The appeal is chosen because the highways objection cannot be designed out. Figures and outcome are illustrative.

Where the written case is the main cost, PlanScope drafts a Planning Statement and supporting documents structured to UK planning policy, flagging missing site facts rather than inventing them, for you or your agent to review before submission.
