The cost of an enforcement appeal under section 174

An enforcement appeal under section 174 of the Town and Country Planning Act 1990 carries no appeal fee. That single fact misleads people into treating it as a low cost option, when the real enforcement appeal cost sits in the evidence each ground needs, the procedure the Planning Inspectorate chooses and the deemed application fee that ground (a) triggers.

Budget it the way you would budget an inquiry rather than the way you would budget a planning application. And budget it before the appeal deadline, because the deadline is the date the notice takes effect and it cannot be extended.

What an enforcement appeal involves

You are appealing a document. The notice states the land, the alleged breach, the reasons, the steps required to remedy it and the period for compliance. The appeal challenges one or more of those elements on specified grounds, and the appeal is lodged with the Planning Inspectorate before the effective date on the notice.

Making the appeal suspends the notice until the appeal is determined or withdrawn. That suspension is worth money on its own, because it keeps a business trading or a tenant in occupation while the case runs.

What it does not do is remove the obligation to think about the end state. If the appeal fails, the compliance period starts from the decision, and the remedial works then have to be funded at a point when the appeal costs have already been spent.

The grounds and the evidence each one needs

The grounds in section 174(2) each demand a different evidence base, and the cost follows the evidence rather than the legal argument.

• Ground (a), that permission ought to be granted: a full planning case. Policy analysis, drawings, often technical reports on the specific objection, and the deemed application fee.
• Ground (b), that the matters alleged have not occurred: factual evidence. Dated photographs, invoices, delivery notes, witness statements.
• Ground (c), that the matters do not constitute a breach: legal analysis of the use, the planning unit and any permitted development right. Usually the least costly ground to run and the one most often overlooked.
• Ground (d), that no enforcement action could be taken because the breach was immune: a continuity of use case built from council tax records, electoral roll entries, tenancy agreements, utility bills, aerial imagery and statutory declarations. Evidence-heavy and the most common reason appellants underestimate the bill.
• Ground (e), defective service: documentary, and rarely decisive on its own.
• Ground (f), that the steps required exceed what is necessary: often technical, requiring an alternative scheme of remediation to be designed and costed.
• Ground (g), that the compliance period is too short: a programme, with contractor evidence.

Running five grounds costs roughly five times as much as running two. Pick the grounds that can be evidenced and drop the rest, because a weak ground invites a costs application against you.

Whether a fee is payable

No fee is payable to the Planning Inspectorate for lodging an enforcement appeal. Where the appeal includes ground (a), section 177(5) treats it as including a deemed application for planning permission, and a fee is payable for that deemed application. If the fee is not paid, the ground falls away and the rest of the appeal continues without it.

The amount sits in the national fee regulations, which are indexed, so take the current figure from the published schedule rather than from a previous appeal. Where a ground (a) case is marginal, the deemed application fee is a reason to decide early rather than to include the ground as insurance.

Professional and legal costs by procedure

The Inspectorate decides the procedure, taking account of the complexity of the issues, whether evidence needs testing and the public interest. You can express a preference and give reasons, and on a straightforward ground (c) or (d) case a written representations appeal is both faster and much less expensive.

Written representations put the whole cost into drafting: a statement of case, the evidence bundle, any technical report and a final comment on the council's statement. A hearing adds attendance, preparation and usually a day of the appellant's time. An inquiry adds an advocate, proofs of evidence for each witness, rebuttal proofs, a statement of common ground and several days in a room.

The jump from written representations to inquiry is not incremental. Where the case can be won on paper, say so in the appeal form and explain why cross-examination is unnecessary.

Deemed application fees on ground (a)

One practical point that saves money: the deemed application is for the matters stated in the notice, not for a scheme of your choosing. If the notice alleges more than you want permission for, the deemed application inherits that scope.

So read the allegation carefully before deciding to run ground (a). Where the notice overstates what exists, challenging the allegation under ground (b) or (c) first may remove the need to pay for a deemed application at all.

Where ground (a) succeeds in part, the inspector grants permission subject to conditions, and those conditions may carry their own cost in remedial works. Price that outcome alongside the appeal, in the same way that a decision on whether to resubmit after a refusal needs the whole cost mapped out, which is the point of resubmitting after a refusal and the cost decision.

Costs awards in enforcement appeals

Either party can apply for an award of costs against the other, and the test is unreasonable behaviour that has caused unnecessary expense. It is not a question of who won.

Behaviour that attracts awards includes pursuing a ground with no supporting evidence, withdrawing at a late stage after the other side has prepared, failing to comply with the timetable, and introducing new material at the inquiry. On the council's side, issuing a notice that is defective on its face, or failing to engage with an obvious permitted development right, can work the same way.

Do not build a budget around recovering costs. Treat an award as an unlikely upside and a costs application against you as a real downside that disciplined ground selection avoids.

Timescales and the risk of non-compliance

The appeal must be made before the notice takes effect. After that, the notice bites and failing to comply becomes a criminal offence under section 179 of the 1990 Act, prosecuted in the magistrates' or Crown Court, with the level of fine set by the court having regard to any financial benefit obtained from the breach.

The council also has powers that cost the owner directly. It can enter the land and carry out the required steps itself under section 178 and recover its expenses as a debt, and it can seek an injunction under section 187B. Both of those are more expensive than compliance.

So the cost comparison is not appeal against nothing. It is appeal, against compliance, against prosecution and council direct action with the expenses added on. Where the development is indefensible, early compliance is almost always the least costly outcome.

Councils expect professional authorship on the technical reports behind an appeal, and a professional reviewer signing off the evidence adds credibility that a self-prepared statement lacks. A draft Planning Statement can carry the policy case and the site description, with the evidence of use and the dated records left to you and your advisers.
