Enforcement notice against breach of condition notice

The difference between an enforcement notice and a breach of condition notice comes down to one thing: you can appeal an enforcement notice to the Planning Inspectorate, and you cannot appeal a breach of condition notice at all. That single distinction shapes which notice a council reaches for, how quickly it bites, and what the recipient can realistically do about it.

Both are served under the Town and Country Planning Act 1990. Both require something to be done within a stated period. After that they diverge.

What each notice does

An enforcement notice is issued under section 172 where the council considers there has been a breach of planning control and that it is expedient to act. A breach means either development carried out without the permission it needed, or a failure to comply with a condition or limitation attached to a permission. The notice must state the matters alleged, the steps required to remedy them, the period for compliance, and the reasons for issuing it. It takes effect on a date not less than 28 days after service.

A breach of condition notice is issued under section 187A and is narrower by design. It can only be served where a condition has not been complied with, and only on the person carrying out the development or the person having control of the land. It requires compliance within a period of not less than 28 days, and it takes effect immediately on service rather than waiting.

Councils also have preparatory and emergency tools. A planning contravention notice compels information about activities on land, and failing to respond is itself an offence. A stop notice or a temporary stop notice can halt activity quickly where the harm is serious.

Appeal rights and where they differ

This is the whole point of the comparison.

An enforcement notice appeal is made under section 174 on specified grounds. They include that permission ought to be granted, that the matters alleged have not occurred, that they do not constitute a breach, that enforcement action is out of time, that the notice was not properly served, that the steps required exceed what is necessary, and that the compliance period is too short. Ground (a), that permission ought to be granted, is treated as a deemed planning application and attracts a fee.

Lodging the appeal suspends the notice until the appeal is determined, which commonly takes many months. That delay is precisely why councils sometimes prefer the other route.

With a breach of condition notice there is no appeal. The recipient complies, applies to vary or remove the condition under section 73, or challenges the notice by judicial review, which tests the legality of the council's action rather than its planning merits.

Time limits for taking action

Enforcement is time limited, and the limits changed recently in England.

Historically the position was four years for operational development and for a change of use to a single dwellinghouse, and ten years for other breaches including breaches of condition. The Levelling-up and Regeneration Act 2023 moved England to a single ten year period, applying to breaches occurring after the date the change took effect, with the older limits continuing to apply to breaches that had already become immune. Which limit applies to a given breach therefore depends on when it occurred, so check the date the new period started rather than assuming.

Once the period has run without enforcement action, the development becomes immune and a certificate of lawfulness for existing use or development can be applied for to confirm it. Deliberate concealment can extend the position, following the line of case law on that point, and the council can seek an order allowing action outside the normal limit.

The limits do not apply to listed building enforcement, which has no equivalent time bar.

Penalties on conviction

Failing to comply with an enforcement notice once it has taken effect is an offence under section 179. It is triable either way, and on conviction the court can impose an unlimited fine, taking account of any financial benefit the offender has gained. Continued non-compliance can bring repeat prosecutions.

Failing to comply with a breach of condition notice is a summary offence dealt with in the magistrates court, with a fine at the level set by the standard scale. It is a lower penalty, but the prosecution is quicker to bring because there is no appeal to wait for.

Both sit alongside the council's other powers. Direct action to carry out the required steps and recover the cost, injunctions in the High Court, and confiscation proceedings in serious cases are all available.

Which notice a council chooses and why

Councils weigh speed against scope.

A breach of condition notice suits a clear, documented failure to comply with a specific condition where the council wants compliance quickly and expects no serious argument. Landscaping not planted. A construction management plan not submitted. Hours of operation exceeded. Materials used that were not approved. The absence of an appeal makes it attractive, and the notice takes effect at once.

An enforcement notice is necessary where the breach is unauthorised development rather than a condition, where the council wants a remedy that goes beyond simple compliance such as demolition or restoration of land, or where it wants a decision that will bind the position after an appeal. It is slower and it carries the risk that an inspector grants permission on ground (a).

Some councils serve both, on different aspects of the same situation. That is lawful and it is not unusual.

Options for the recipient of each

If you receive an enforcement notice, the sequence is tight. Read the compliance date and the effective date, diary both, and get advice quickly, because the appeal must be lodged before the notice takes effect and there is no discretion to extend that. Consider whether a retrospective application would be a better route than an appeal, whether any ground of appeal is actually available, and whether partial compliance reduces the exposure. A well-evidenced Planning Statement supporting a deemed or retrospective application is the substance of a ground (a) case.

If you receive a breach of condition notice, comply or move fast on a section 73 application to vary the condition, and tell the council you have applied. Prosecution is discretionary, and authorities will usually hold off where a real application to regularise the position is in front of them. Do not ignore it in the hope of an appeal that does not exist.

For neighbours and parish councils watching a breach, the practical route is to report it with dates, photographs and a description of what has changed, then ask the council what it intends to do. Enforcement is discretionary, and a council is not obliged to act where it considers the breach causes no material harm. That is frustrating, and it is the law.

Where the underlying problem is that the permission no longer matches what is being built, scoping the supporting documents for a fresh application through the report types by category is usually a better use of energy than arguing about the notice. Reform to enforcement powers has been frequent, so follow developments on the planning law updates timeline.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.
