A Planning Contravention Notice can feel more serious than an ordinary council email because it is a statutory information-gathering tool. A local planning authority may use one where it appears that a breach of planning control may have occurred and it needs more information before deciding what, if any, enforcement action to take.
Receiving a notice does not mean the council has proved a breach or decided to serve an enforcement notice. It does, however, create legal obligations that should be handled carefully. A property owner who is unsure how to answer may seek guidance from a planning contravention notice solicitor or another planning-law professional. Aldwych Legal is a Central London-based legal consultancy supporting clients across England with planning disputes, enforcement responses and strategic case preparation; where reserved legal work is required, it works with external regulated solicitors and barristers.
What Is a Planning Contravention Notice?
A Planning Contravention Notice, usually called a PCN, is issued under section 171C of the Town and Country Planning Act 1990. It may be served where it appears to the local planning authority that there may have been a breach of planning control in relation to land.
Its purpose is investigative. A PCN can require information for enforcement purposes about operations, the use of land or activities taking place there. It can also invite the recipient to explain how a suspected breach might be satisfactorily remedied.
A PCN is not itself an enforcement notice. It does not determine that development is unlawful, and it does not carry the same statutory appeal procedure as an enforcement notice.
Why Might a Council Serve One?
A planning enforcement investigation can begin after a complaint, site visit, review of planning records or other information. The council may use a PCN to establish facts such as when building work took place, how premises are being used, who has an interest in the land or what permission is said to authorise an activity.
Government guidance makes clear that a PCN should not be used as a general investigative trawl. It is intended for cases where a breach may have occurred and the authority needs further information before deciding whether enforcement action is appropriate.
The procedure is discretionary. A council does not have to serve a PCN before considering an enforcement notice or another appropriate enforcement measure.
An Informal Letter Is Different
An informal enforcement letter may ask for an explanation, documents or a voluntary site visit. It should be taken seriously, but it does not have the same statutory status as a PCN.
The recipient should identify the document received, understand the allegation and check the planning history before providing detailed answers. Decision notices, approved drawings, previous applications and council correspondence may show that the position is different from the council’s initial understanding.
Aldwych Legal supports evidence-led preparation in planning disputes, which can include reviewing planning histories and organising material before a response is finalised.
The 21 days Must Be Taken Seriously
Section 171D deals with non-compliance. If, after the end of the 21 days beginning with the day on which the PCN was served, the recipient has not complied with a requirement of the notice, an offence can arise. There is a statutory defence where the person can prove a reasonable excuse for failing to comply.
It is also an offence, knowingly or recklessly, to make a statement purporting to comply with a PCN that is false or misleading in a material particular.
The response should therefore not be completed by guessing. If an important date, use or ownership detail can be checked, it should be checked. Where a question is unclear or evidence conflicts, obtaining planning enforcement legal advice may be more sensible than presenting an uncertain answer as fact.
Build the Response Around Evidence
The available records should support a good PCN response. Depending on the allegation, useful material may include:
- planning decision notices and approved drawings;
- dated photographs;
- invoices and construction records;
- tenancy or occupancy documents;
- business and utility records;
- historic mapping or aerial imagery; and
- earlier correspondence with the council.
A chronology can be particularly useful where the dispute concerns when a use began or when works were completed. It should distinguish dates that can be proved from dates that are only estimated.
Aldwych Legal supports planning-dispute case preparation where the planning history or evidence is complicated. Owners can also review planning enforcement support when considering how an investigation, evidence and possible enforcement routes fit together.
Do Not Make Unnecessary Admissions
A recipient must answer a PCN truthfully, but that does not require accepting the council’s legal interpretation of the facts.
An owner may be able to confirm that works were completed on a certain date while disputing that those works required planning permission. A landlord may accurately describe the way a property is occupied while disagreeing that a material change of use occurred.
Responses should therefore separate facts from legal conclusions. Where the planning position is disputed, planning breach legal advice may help keep the answer accurate and focused on what the evidence actually supports.
Consider Whether the Matter Can Be Resolved Early
A PCN can create an opportunity to identify a practical solution before stronger enforcement powers are used. Depending on the circumstances, discussions may concern remedial works, stopping or modifying an activity, a retrospective planning application or a Lawful Development Certificate.
None of these routes is automatic. Retrospective planning permission may be appropriate in some cases, but permission is not guaranteed and making an application does not automatically stop enforcement. A Lawful Development Certificate answers a different question: whether a use, operation or activity is lawful rather than whether permission should be granted on its planning merits.
What Happens After the Response?
After reviewing the PCN response and other evidence, the council may decide that no breach has occurred, continue investigating, seek further discussion or consider formal enforcement where it is expedient to do so.
If an enforcement notice is later served, it has its own statutory appeal route. The effective date on that notice is critical: the Planning Inspectorate must receive any enforcement appeal before the notice takes effect.
Other measures are different. A breach of condition notice does not have the same appeal route as an enforcement notice, while stop notices and temporary stop notices follow separate procedures.
Keep Other Property Rules Separate
Planning control should not be confused with Building Regulations, licensing, restrictive covenants, title issues or other property-law requirements. Compliance with one regime does not automatically establish compliance with another.
This distinction should be maintained even where several issues affect the same property. Aldwych Legal supports planning-dispute preparation across England, but separate regulatory or private-law questions may require their own analysis.
Conclusion
A Planning Contravention Notice is a formal request for information, not a finding that a planning breach has already been proved. The recipient should identify exactly what the council is asking, check the planning history, gather reliable evidence and respond within the statutory framework.
The 21-day deadline matters, as does the accuracy of every material statement. Property owners should avoid guessing, making unnecessary admissions or assuming that retrospective permission will automatically resolve the situation.
Aldwych Legal can support evidence-led planning-dispute preparation and enforcement responses, with external regulated practitioners involved where reserved legal work is required. Early organisation can help clarify the facts and place the recipient in a stronger position if the council later considers formal enforcement.
