Changing the hours a use operates
Hours can sit in a planning condition, a section 106 agreement, a premises licence, or nowhere at all. Find out which before you apply, then build the noise and dispersal evidence.
Varying an opening hours condition is a section 73 application in most cases: an application to develop without complying with a condition previously imposed, under section 73 of the Town and Country Planning Act 1990. It carries a reduced fee, the council can only consider the condition you have asked it to look at, and success gives you a new permission that sits alongside the old one rather than replacing it.
Before you apply, find out where your hours actually come from. A surprising number of premises have no planning restriction on hours at all, because the limit sits in the premises licence and the planning system is the wrong door to knock on.
Where hours come from in a permission
Check the decision notice for the original permission and every subsequent one. Hours can be controlled in four ways.
A condition on the planning permission is the usual mechanism, worded either as opening hours to customers or as hours of operation covering deliveries and plant. A section 106 obligation occasionally controls hours where the council wanted a longer-term commitment. The premises licence under the Licensing Act 2003 sets licensable hours for alcohol, regulated entertainment and late night refreshment, and those are separate from planning. And for many older premises, there is no restriction at all, because the use predates the permission regime or was granted unconditionally.
Where nothing restricts hours in planning terms, extending them is not development and no application is needed. Intensification can become a material change of use in extreme cases, but that is a high bar and it turns on the character of the use rather than the clock.
Section 73 against a fresh application
A section 73 application is quicker and less expensive, and it is limited. The council considers only the condition in question, and it can refuse, grant with the condition varied, or grant with the condition removed. It cannot use the application to revisit the whole permission.
There is a limit worth knowing. Following the Court of Appeal's decision in Finney v Welsh Ministers, a section 73 permission cannot be granted where the variation would conflict with the description of the development in the original permission. If the description itself specifies the hours, section 73 is the wrong route and you need a fresh application for the use.
| Route | When it fits |
|---|---|
| Section 73 variation | A hours condition on an extant permission, description silent on hours |
| Section 96A non-material amendment | A minor correction, such as a 15-minute change or a clerical error |
| Fresh full application | Hours in the description, or the use itself is changing |
| Temporary permission | A trial period agreed with the officer |
Section 96A is narrower than people hope. A change has to be non-material in the context of the whole permission, and an extra hour of trading on a Friday night next to housing rarely qualifies.
Evidence on noise and dispersal
The planning objection to later hours is almost always noise, and it comes in three forms that need separate treatment.
Plant noise from extraction fans, chillers and air conditioning is assessed under BS 4142:2014+A1:2019, comparing a rating level for the specific sound against the measured background at the nearest noise-sensitive facade. Later hours matter because the background falls after midnight while the plant keeps running, so a unit that passed at 10pm can fail at 1am. A Noise Impact Assessment should model the proposed hours rather than the current ones.
Noise from inside the premises, particularly amplified music, needs a break-out assessment and usually a limiter condition. The agent of change principle in national policy matters here, and the position for live music venues facing new residential neighbours is worth understanding before you argue it.
Dispersal noise is the one that decides applications. Customers leaving, taxis waiting with engines running, doors, smoking areas, and the wheelie bins being moved at 2am. Quantifying it is hard, and environmental health officers know that, which is why a written dispersal and management plan carries more weight here than a further page of modelling. Say who supervises the exit, where smokers stand, when waste is collected, and how the taxi arrangement works.
Trial periods and temporary permissions
Where the officer is unconvinced, ask for a temporary permission. A permission limited to 12 or 18 months lets the council see whether the predicted harm materialises, and gives you a record of complaint-free operation to rely on when you apply for the hours permanently.
Two conditions on that strategy. Keep your own log of any complaints and how you responded, because the council's record will be incomplete. And apply for the permanent permission well before the temporary one expires, since trading beyond it without permission puts you in breach and undermines the argument you have spent a year building.
Licensing hours against planning hours
The two regimes are separate, and both have to be satisfied. A premises licence permitting sales until 1am does not authorise opening until 1am where a planning condition says 11pm, and the planning condition is the one enforced by the council's planning enforcement team.
Late night refreshment, meaning the supply of hot food or hot drink to the public between 11pm and 5am, is a licensable activity under the Licensing Act 2003 in its own right. A takeaway seeking hours past 11pm therefore needs both a licence variation and, usually, a planning variation. Run them together rather than in sequence, but keep the documents distinct. Licensing committees work to the four licensing objectives, planning committees work to the development plan and material considerations, and an application that mixes the two arguments persuades neither.
Where a cumulative impact assessment or an early morning restriction order applies to the area, the licensing route is harder, and that is worth checking before you spend on planning evidence.
Neighbour consultation and how to handle it
A section 73 application is publicised like any other, with neighbour notification or a site notice and a consultation period of at least 21 days. For hours applications the objection rate is high and the objections are specific, which is useful.
Talk to the immediate neighbours before you apply. Most hours disputes are about a handful of recurring irritations, and three of them can usually be fixed by management rather than by argument: the bin store, the extraction fan, and where staff park. Offering conditions that address those points in the application itself removes the reason for most objections.
Do not offer a condition you cannot comply with. Conditions must be precise and enforceable, and a promise to close windows after 9pm that nobody monitors does more harm than good when enforcement officers arrive.
What to submit
- The application form for a variation of condition, with the existing condition quoted in full and the proposed wording written out.
- A short Planning Statement explaining the planning history, the condition's original purpose, what has changed, and how the development plan policies on amenity and town centre vitality apply.
- Noise evidence proportionate to the change, covering plant, break-out and dispersal at the proposed hours.
- A management plan dealing with dispersal, deliveries, waste collection, smoking and staff departure.
- Where cooking is involved, a Ventilation and Extraction Statement confirming the discharge point, filtration and maintenance regime.
- A transport note if the extended hours change vehicle movements or parking demand materially.
Drafting the supporting statement and the noise scope on PlanScope gives you a structure to hand to the acoustician. This is general guidance rather than legal advice, so check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
Do I need planning permission to open later?
Only if a planning control restricts your hours. Check the decision notice for every permission on the premises and any section 106 agreement. Where nothing restricts hours in planning terms, extending them is not development. Where a condition does restrict them, a section 73 application to vary that condition is the usual route and carries a reduced fee.
What is a section 73 application?
An application under section 73 of the Town and Country Planning Act 1990 to develop without complying with a condition previously imposed. The council can only consider the condition you have identified, and a grant creates a new permission alongside the original. It cannot be used where the variation would conflict with the description of development in the original permission.
Are licensing hours and planning hours the same thing?
No. They are separate regimes and both must be satisfied. A premises licence permitting sales until 1am does not authorise opening until 1am where a planning condition says 11pm, and the planning condition is the one the council's planning enforcement team acts on. Late night refreshment between 11pm and 5am is separately licensable.
What noise evidence is needed for later hours?
Plant noise assessed under BS 4142 at the proposed hours rather than current ones, because background sound levels fall after midnight while extraction keeps running. Break-out assessment where amplified music is involved. And a written dispersal and management plan covering customers leaving, taxis, smoking areas and waste collection, which carries more weight than further modelling.
Can I ask for a trial period instead?
Yes. A temporary permission for 12 or 18 months lets the council see whether the predicted harm occurs and gives you an operating record to rely on later. Keep your own complaint log, because the council's will be incomplete, and apply for the permanent permission before the temporary one expires rather than trading on beyond it.
