Chesterfield enforcement notice collapses over wrong ‘party venue’ allegation

A Chesterfield enforcement notice aimed at what the council called a “party venue” has been quashed after an Inspector found the alleged breach simply had not happened.

Chesterfield Borough Council said Five Acres, Piccadilly Road, had changed from a Use Class C3 dwellinghouse to a party venue. But Inspector John Braithwaite found the evidence instead pointed to occupation as a home alongside short-term holiday letting. He allowed the appeal and quashed the notice on 28th September 2026. The appeal decision APP/A1015/C/25/3373897 sets out the Inspector’s reasoning.

For anyone drafting or appealing an enforcement notice, the decision is a sharp reminder that the allegation must match the breach the evidence actually establishes. An Inspector can correct some errors, but cannot simply substitute a materially different enforcement case where that would prejudice the parties.

Chesterfield enforcement notice targeted wrong ‘party venue’ use

Five Acres is a detached dwelling which had been advertised and used for short-term letting. The council relied on advertisements describing the property as suitable for parties and reviews saying parties had taken place.

That was not enough to prove the breach written into the notice.

Inspector Braithwaite found that parties had occurred only a few times and that the property had not been let solely for that purpose. If it were treated as having a single use, he considered the evidence pointed to short-term holiday letting.

There was another important fact. The appellant’s agent said the owner occupied the property for most of the time and that it was predominantly let at weekends. The council did not challenge that account.

On that evidence, the Inspector described the actual pattern as a mixed use of a C3 dwellinghouse and short-term holiday letting. The alleged change to a party venue had therefore not occurred as a matter of fact, so the appeal succeeded on ground (b).

That finding needs handling carefully. It does not establish that every short-term let remains within C3, nor did the Inspector decide the planning merits of the short-term letting itself. Once ground (b) succeeded and the notice was quashed, there was no need to determine the ground (a) case.

No PCN left the council without precise occupation evidence

The decision also highlights the practical value of a Planning Contravention Notice when the precise nature of a use is uncertain.

On the evidence before him, Inspector Braithwaite found that Chesterfield had not served a PCN before taking enforcement action.

The Inspector said questions in a PCN could have provided the council with information about the property’s precise use.

A PCN is not a compulsory precondition to every enforcement notice, and this decision does not turn it into one. The point is evidential. Where a property alternates between owner occupation, letting and other activity, carefully targeted questions may establish the frequency, duration, occupiers and purpose of those uses before an allegation is fixed in a notice.

Here, the absence of that information mattered because the Chesterfield enforcement notice alleged a specific party venue use which the evidence did not support.

Section 176 could not rescue the Chesterfield enforcement notice

An enforcement notice does not automatically fail because its wording contains an error. Section 176 of the Town and Country Planning Act 1990 gives an Inspector powers to correct defects, errors and misdescriptions where this can be done without injustice.

But changing “party venue” into either short-term holiday letting or a mixed C3 and short-term holiday use would have changed the substance of the case the parties had prepared to argue.

Inspector Braithwaite concluded that changing the allegation in that way would prejudice both parties. The Chesterfield enforcement notice therefore could not be repaired by rewriting the allegation on appeal.

The point echoes the practical distinction we recently saw in the Yalding enforcement notice appeal. Section 176 can correct an enforcement notice, but it is not a licence to replace one alleged breach with a materially different one after the appeal has begun.

Our guide to the grounds of enforcement appeal explains how ground (b) works and why the factual allegation in the notice matters from the outset.

The compliance requirement had a second problem

The successful ground (b) appeal was enough to quash the notice, but the Inspector went further and explained what would have happened if he had needed to consider its validity.

The requirement told the appellant to cease any operation on the land outside the permitted C3 dwellinghouse use.

Inspector Braithwaite considered that requirement too vague for the appellant to know what she had to do to comply. He would therefore have found the notice invalid for that reason as well as the problems with the allegation.

For the Chesterfield enforcement notice, that is a separate drafting lesson. The allegation identifies the breach. The compliance requirement must then tell the recipient, with sufficient clarity, what needs to stop or what steps need to be taken.

A requirement framed by reference to anything outside a planning use class may sound comprehensive, but it risks leaving the recipient to guess which particular activities the authority says must cease.

Parties do not automatically create a separate planning use

Perhaps the most quotable passage comes at the end of the decision.

The Inspector said “the holding of parties, associated with residential occupation of a property, is one of many uses that fall within Use Class C3”.

That should not be stretched into a general rule that any level of party activity is residential. Planning remains fact-sensitive. A property genuinely operated as a dedicated event or party venue could present a very different character of use.

Likewise, the planning status of serviced accommodation and short-term lets depends on the facts, including the nature and pattern of occupation and whether a material change of use has occurred.

What this appeal does show is that occasional parties, including parties mentioned in guest reviews, do not by themselves prove that a dwelling has become a separate “party venue”. The authority still has to identify the actual use and allege the correct breach.

Why the Chesterfield enforcement notice matters

The notice failed because the case pleaded by the council was not the case demonstrated by the evidence.

For enforcement teams, the obvious practical step is to investigate occupation patterns before choosing the allegation, particularly where online advertising gives only part of the picture. A PCN can be especially useful where the distinction between home occupation, short-term letting and a separate commercial or event use turns on facts known mainly to the owner or occupier.

For appellants, the decision is a reminder to test the wording of the notice against what has actually happened on the land. A ground (b) appeal is about fact, not whether the alleged use would be acceptable in planning terms.

And for both sides, prejudice remains the dividing line when a defective allegation might otherwise be corrected. Minor drafting errors can sometimes be repaired. Replacing a party venue allegation with a different single or mixed use was too fundamental in this case.

The Chesterfield enforcement notice was quashed. The decision should not be reported as granting a general planning approval for short-term letting at Five Acres, or as deciding that party activity can never amount to a material change of use.
