Stop Notices and Temporary Stop Notices: Urgent Options for Owners and Developers
A stop notice can disrupt a development or business operation very quickly. Construction may have to halt, a commercial activity may need to cease, or an owner may have to reconsider how a site is being used. A temporary stop notice can be even more immediate because it takes effect at once. For owners and developers in England, identifying exactly which document has been served is the priority.
A stop notice and a temporary stop notice are not interchangeable, and neither is the same as an ordinary council enforcement letter. Their statutory basis, timing and relationship with other enforcement action differ. Where the consequences are serious, a stop notice planning solicitor or another planning-law professional may help assess the position. Aldwych Legal supports clients across England with planning disputes, enforcement responses and strategic case preparation.
What Does a Stop Notice Do?
A stop notice is linked to an enforcement notice. Under section 183 of the Town and Country Planning Act 1990, a local planning authority can use it to prohibit some or all of the activities forming part of the alleged breach identified in the related enforcement notice.
It cannot be served independently. The associated enforcement notice must already have been issued. Its purpose is to stop specified activity before the compliance period in that enforcement notice expires. The recipient should therefore read both documents together. The enforcement notice sets out the alleged breach and remedial requirements, while the stop notice focuses on the activity that must cease sooner.
When Does a Stop Notice Take Effect?
The stop notice must state when it takes effect. Ordinarily, that date must be at least three days, but no more than 28 days, after service. In special circumstances, the authority may specify an earlier date, but it must give reasons.
The recipient should identify the activity prohibited, the effective date and whether the associated enforcement notice should be appealed. If an enforcement appeal is required, the Planning Inspectorate must receive it before the effective date stated on that enforcement notice. Ongoing discussions with the council do not suspend that deadline.
How Is a Temporary Stop Notice Different?
A temporary stop notice, usually called a TSN, can be used where the local planning authority considers that an activity amounting to a breach of planning control should stop immediately.
Unlike an ordinary stop notice, a TSN does not depend on an enforcement notice having been issued first. It takes effect immediately and must identify the activity that is to cease.
A TSN may require an activity to stop, or be reduced or minimised, but it is essentially prohibitory. It is not intended to require positive remedial works. Aldwych Legal can help organise the planning history and evidence where the council’s underlying allegation is disputed.
For notices issued in England on or after 25 April 2024, a TSN can remain in force for up to 56 days or for a shorter period stated in the notice.
What Should the Recipient Do First?
The response should be practical and evidence-led. A recipient should:
- keep the complete notice and any attached plan;
- record the date of service and effective date;
- obtain the associated enforcement notice where an ordinary stop notice has been served;
- identify precisely which activity must cease;
- preserve planning permissions, approved plans, photographs and site records; and
- record any immediate operational or financial consequences.
Continuing a prohibited activity simply because the owner disagrees with the council can increase the risk significantly.
Why Proportionality Matters
Before serving a stop notice, the authority should be satisfied that there has been a breach of planning control and that it is expedient for the relevant activity to stop before the enforcement notice’s compliance period expires.
Government guidance says the requirements should prohibit only what is essential to safeguard amenity or public safety in the neighbourhood or to prevent serious or irreversible environmental harm.
For a TSN, the authority must also be satisfied that a breach has occurred and that it is expedient for the activity to stop immediately. It must state its reasons.
Where urgent council action affects an active site, planning enforcement advice can help owners understand how the stop notice, underlying enforcement issue and available evidence fit together.
Can a Stop Notice Be Appealed?
There is no ordinary appeal to the Secretary of State against the prohibitions in a stop notice. The same applies to a temporary stop notice.
That does not mean the council’s decision is immune from legal challenge. The validity of a notice, or the lawfulness of the authority’s decision to issue it, may potentially be challenged through judicial review in the High Court. A person affected by a TSN can also make representations to the local planning authority.
Judicial review is not a fresh planning appeal on the merits. It concerns whether the authority acted lawfully and has its own procedural requirements and deadlines.
Where an associated enforcement notice is also disputed, that notice has its own statutory appeal route. Aldwych Legal supports evidence-led planning-dispute preparation where several enforcement procedures overlap.
What Happens if the Notice Is Ignored?
Contravening either type of notice can amount to a criminal offence. On conviction, the court can impose an unlimited fine.
For an ordinary stop notice offence, the court must have regard to any financial benefit that has accrued, or appears likely to accrue, because of the offence. This can be important where a commercial activity continues after it has been prohibited.
Disagreement with the council should therefore not be treated as permission to carry on regardless. If the notice is considered unlawful, the proper challenge route should be examined promptly.
Compensation Is Limited
Financial loss caused by a stop notice does not automatically create a right to compensation. For both ordinary stop notices and temporary stop notices, compensation can arise only in defined statutory circumstances and is subject to limitations.
Where the commercial impact is substantial, an urgent planning enforcement solicitor or other appropriate professional may help assess the immediate planning position and available legal routes.
Stopping the Activity Does Not Resolve the Underlying Breach
Complying with the prohibition deals with the immediate notice, but the planning dispute remains.
Depending on the circumstances, the next stage may involve an enforcement appeal, negotiation, remedial works, a retrospective planning application or consideration of a Lawful Development Certificate.
Retrospective planning permission is not guaranteed and does not automatically stop enforcement. Planning control should also be kept separate from Building Regulations, licensing, restrictive covenants and title issues.
Conclusion
Stop notices and temporary stop notices are among the more urgent planning enforcement tools available to local planning authorities in England. An ordinary stop notice depends on an existing enforcement notice, while a temporary stop notice can take effect immediately and can currently remain in force for up to 56 days.
Neither notice carries an ordinary appeal to the Secretary of State against its prohibitions. Owners and developers should identify the document, understand exactly what must stop, preserve relevant evidence and protect any separate enforcement-notice appeal deadline.
