Receiving a planning enforcement notice is very different from receiving an informal council letter. An informal enquiry may be part of an investigation, while an enforcement notice is a statutory document that can require a use to stop, works to be removed or other remedial steps to be taken.
In England, an appeal can be made on one or more of seven statutory grounds under section 174(2) of the Town and Country Planning Act 1990. Choosing the right ground depends on what the notice alleges, the planning history and the evidence. Someone considering an enforcement notice solicitor or other planning-law professional should begin by reading the notice carefully rather than using every ground automatically. Aldwych Legal supports clients across England with planning disputes, enforcement responses, appeals and strategic case preparation.
Protect the Effective-Date Deadline First
The notice should state the date on which it takes effect. The Planning Inspectorate must receive an enforcement appeal before that effective date; there is no general discretion to accept an ordinary late appeal.
This deadline should be protected even if discussions with the local planning authority are continuing. Negotiation, a request for more time or consideration of a retrospective planning application does not by itself suspend the appeal deadline.
Aldwych Legal can assist with organising planning history and case evidence before a response is finalised, while external regulated solicitors or barristers may be involved where reserved legal work is required.
Ground (a): Planning Permission Ought to Be Granted
Ground (a) puts the planning merits in issue. The appellant argues that planning permission ought to be granted for the breach alleged in the notice, or that the relevant condition or limitation ought to be discharged.
Using ground (a) creates a deemed planning application, and a fee is payable. The appellant should address the development plan, material planning considerations and any conditions that could make the development acceptable.
Current law restricts ground (a) in certain cases where a related retrospective planning application has already been made. Retrospective permission should therefore not be treated as an automatic first step or as something that automatically stops enforcement.
Ground (b): The Alleged Matters Did Not Occur
Ground (b) is factual. It applies where the appellant says the matters described in the notice did not happen.
For example, the council may allege that a structure was erected or a particular use began, while the appellant says that allegation is factually wrong. Photographs, plans, inspection material, tenancy records and witness evidence may be relevant.
Ground (b) is different from arguing that the activity happened but did not require planning permission. That belongs underground (c).
Ground (c): What Happened Was Not a Breach
Ground (c) accepts the argument that the matters occurred, but says they did not amount to a breach of planning control.
This may apply where works were already authorised by planning permission, fell within permitted development rights, or where an alleged change of use was not material. The interpretation of an existing permission or condition can also be important.
Decision notices, approved drawings and the planning history may therefore be central. Aldwych Legal can help clients organise that material when assessing whether the council’s description of the breach is legally and factually sustainable.
Ground (d): Enforcement Action Could No Longer Be Taken
Ground (d) argues that, when the enforcement notice was issued, the relevant statutory enforcement period had already expired.
England’s enforcement time-limit rules changed on 25 April 2024. Current guidance states that operational development substantially completed on or after that date and an unauthorised change of use to a single dwellinghouse occurring on or after that date are generally subject to ten years. Transitional rules preserve the former four-year periods for relevant earlier cases, while other breaches generally remain subject to ten years.
Historic photographs, invoices, tenancy records, business documents, utility records, mapping and witness evidence may matter. For material changes of use, evidence may also need to demonstrate continuity without significant interruption.
Anyone seeking to appeal a planning enforcement notice on ground (d) should avoid relying on a vague statement that the development has “been there for years”.
Ground (e): The Notice Was Not Properly Served
Ground (e) concerns whether copies of the enforcement notice were served as required by section 172.
The authority must serve the notice on the owner and occupier and on other persons with materially affected interests in the land, subject to the statutory rules. Service also has timing requirements.
A service failure does not automatically decide the appeal. Certain defects can be disregarded where no substantial prejudice has been caused. The appellant should identify who should have received the notice, who actually received it and what prejudice resulted.
Ground (f): The Requirements Go Further Than Necessary
Ground (f) argues that the steps required by the notice, or the activities it requires to cease, go beyond what is necessary to remedy the breach or resulting injury to amenity.
The appellant should identify a lesser requirement that would still achieve the notice’s purpose. Ground (f) cannot be used simply to argue that planning permission should be granted; if the planning merits are to be considered, ground (a) is the relevant route.
Information on evidence-led planning permission disputes can help owners understand how the notice’s requirements, planning history and appeal grounds fit together.
Ground (g): The Compliance Period Is Too Short
Ground (g) challenges the period allowed for compliance. The appellant argues that the time specified in the notice falls short of what should reasonably be allowed.
A persuasive case should explain why more time is needed and suggest a realistic alternative period. Relevant factors may include demolition or remedial work, relocation arrangements or other practical steps genuinely required for compliance.
Where ground (g) is the only concern, discussion with the council may also be worthwhile because the authority has powers in appropriate circumstances to extend a compliance period.
Match Each Ground to Clear Evidence
The current Planning Inspectorate guide states that clear facts must support all grounds. Grounds (b), (c), (d) and (e) are often described as the legal grounds, and the appellant is responsible for supporting them. The evidential test is the balance of probabilities.
A useful case file may include:
- the enforcement notice and its plan;
- planning permissions and approved drawings;
- historic photographs and mapping;
- invoices, tenancy or business records;
- council correspondence; and
- technical or witness evidence where appropriate.
A planning enforcement appeal solicitor or another planning professional can help distinguish grounds that are genuinely supported from arguments that belong under another procedure.
Keep Planning Enforcement Separate From Other Controls
An enforcement appeal concerns planning control. It does not automatically determine Building Regulations compliance, licensing, restrictive covenants, title rights or other property-law obligations.
Receiving an enforcement notice should also not be confused with receiving a breach of condition notice. A breach of condition notice has a different challenge route and does not carry the same seven-ground appeal procedure.
Aldwych Legal supports planning-dispute preparation across England, but separate regulatory or private-law issues may require their own analysis.
Conclusion
The seven grounds answer different questions. Ground (a) concerns planning merits; grounds (b) and (c) distinguish between what happened and whether it amounted to a breach; ground (d) concerns time limits; ground (e) concerns service; ground (f) addresses excessive requirements; and ground (g) concerns insufficient time for compliance.
The strongest appeal is selective and evidence-led. Most importantly, the Planning Inspectorate must receive the appeal before the effective date stated on the notice. There is no discretion to accept an ordinary late appeal. Aldwych Legal can support clients with planning-dispute strategy and evidence preparation, but the correct grounds and procedure will always depend on the individual notice and facts.
