Walkthrough: an hours condition varied under section 73

A section 73 application to vary a condition is how an established business changes an opening hours restriction it can no longer live with, and it produces a fresh planning permission rather than an amended one. The walkthrough below is illustrative: a café in a suburban parade, permitted four years earlier as a change of use from a former estate agent, trading under a condition limiting opening to 8am until 6pm Monday to Saturday and closed on Sundays. The operator wanted 10pm closing six days a week and Sunday trading from 10am.

The application succeeded, with changes. What follows is the sequence and the evidence that got it there.

The permission and the hours condition it carried

The original change of use permission carried seven conditions. The hours condition was condition 4, and it was worded as a restriction on opening to customers rather than on the hours of use of the premises, which turned out to matter.

A restriction on customer opening does not control staff arriving at 6am to bake, deliveries at 7am or waste collection at 5.30am. Some councils write hours conditions to cover all activity on the site, and those are much harder to work around. Read which kind you have before assuming the problem is the one you think it is.

Condition 4 also had no reason given beyond a reference to protecting the amenity of nearby residential occupiers. A thin reason is useful later, because a condition has to be necessary and reasonable, and one supported by a single generic sentence is easier to argue about than one referencing a specific evidenced concern.

Why the condition stopped working

Evening trade was the whole point of the business model by year three. The parade had gained two other food uses, the bus route had been extended, and the café's daytime trade had been eroded by a supermarket concession opening at the other end.

None of that is a planning argument on its own. What made it a planning argument was the change in the character of the parade, which is a material consideration, and the absence of any evidence that the premises had caused a problem during the hours it already had.

The operator had one thing worth more than any consultant report: four years of trading with no complaints to the council's environmental health team. That record is obtainable from the council and it is the single most useful document in an hours variation.

Choosing between section 73, section 96A and a fresh application

Three routes existed. They are not interchangeable.

A non-material amendment under section 96A of the Town and Country Planning Act 1990 is for changes that are not material. Extending closing time by four hours and adding a trading day is plainly material, so that route was out. Councils will reject a section 96A application of that kind quickly, and the fee is not returned.

A fresh full application would have reopened everything: the principle of the use, the shopfront, the extraction, the bin store. Four years on, with a new local plan adopted in the interim, that meant re-arguing settled matters against policies that had changed.

A section 73 application under the 1990 Act was the right route. It asks for permission to carry out the development without complying with a specified condition, and the council's consideration is confined to the condition in question. It cannot be used to extend the time limit for implementation, and it cannot be used to change the description of development. The section 73 route is the standard mechanism for this and is well understood by officers.

One caution worth recording. The Levelling-up and Regeneration Act 2023 inserted a further route for minor variations, section 73B, with a different test. Commencement of that provision has been staged, so check whether it is in force and what guidance sits behind it before choosing between the two.

The evidence assembled

Four documents went in with the application.

A noise assessment, prepared by an acoustic consultant, measuring background sound levels at the nearest residential facade during the proposed additional hours, and assessing plant noise from the existing extraction system running later. Councils expect a suitably qualified author for this work, and professional review before submission is strongly advised. The Noise Impact Assessment dealt with plant separately from customer activity, because the two are assessed differently.

A management plan covering the practical controls: no external seating after 8pm, doors closed after 8pm, a dispersal notice asking customers to leave quietly, a named duty manager, and a log for any complaint received.

A servicing statement confirming delivery and waste collection times, which stayed within the original hours and were offered as a condition in their own right.

A short planning statement setting the proposal against the adopted local plan's town centre and amenity policies, with the four year complaint free record and the changed composition of the parade as the material considerations relied on.

Consultation and the objections

Twelve neighbours were notified and a site notice went up. Four objections came in.

Two were about noise from customers leaving, one was about the smell of cooking in the evening, and one was a general objection to the parade becoming an evening destination. The odour objection was the one with teeth, because the existing extraction had been designed for daytime operation and the issue of evening cooking odour is a distinct question, as a takeaway change of use answered on odour shows.

The response was to commission a short addendum from the extraction engineer confirming the system's capacity and filtration, and to offer a condition requiring the filters to be maintained to a stated schedule with records available to the council.

The two noise objections were answered with the dispersal measures and by offering a 9.30pm last entry restriction. Offering a restriction you can live with is usually better than fighting for the full ask, because it gives the officer something to point at in the report.

The new decision notice and the conditions restated

Permission was granted with 10pm closing Monday to Saturday and 9pm on Sundays, rather than the 10pm across the board that was sought.

The important feature of the decision notice is structural. A section 73 permission is a new permission for the whole development, and it carries a complete set of conditions, not just the varied one. All seven original conditions were restated, two were updated to reflect the current approved drawings, and three new conditions were added covering the management plan, the filter maintenance schedule and last entry.

That restatement is where operators get caught. A condition that the council omits from the new notice falls away, which occasionally works in an applicant's favour, and a condition the council tightens on the way through binds the business from the moment the new permission is implemented. Check every condition on the new notice against the old one, line by line, before relying on it.

Both permissions now exist in parallel. The business operates under the new one, and the original remains extant but unused.

What changed in practice, and what did not

Trading hours changed. The premises licence did not.

Planning conditions and a premises licence under the Licensing Act 2003 are separate regimes with separate applications, separate committees and separate appeal routes. Where both apply, the more restrictive governs in practice, so a café with planning permission to 10pm and a licence to 9pm closes at 9pm. Vary both or vary neither.

Building Regulations were untouched, because nothing physical changed. The business rates position did not change either. What did change, quietly, was the enforcement exposure: three new conditions mean three new ways to be in breach, and the filter maintenance records now need to exist.
