Use Classes and Change of Use

Alternating uses: one building, two timetabled uses

7 min readBy PlanScope Editorial Team

Sharing a building by timetable does not automatically create a second planning use. Here is where the line falls and what the application should say.

A building used by a church on Sundays and a nursery on weekdays may have one planning use or two, and the answer is not decided by the timetable. It is decided by whether either activity is ancillary to the other, and by where the boundary of the planning unit falls. Get that wrong at application stage and you end up with a permission that does not cover half of what actually happens in the building.

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

Whether timetabled sharing creates a second use

Sharing a building by timetable does not, on its own, create a second planning use. A village hall hosting a pilates class on Tuesday and a parish council meeting on Thursday is still a hall. Those activities are the hall being a hall.

The question is whether an occupier has taken a defined part of the building, or defined periods, for an activity that is a use in its own right rather than one of the things the building exists to host. A nursery operating five days a week for forty-five weeks of the year, with its own staff, its own registration, its own fixtures, its own parents arriving twice daily, is doing more than hiring a room.

Scale, regularity and exclusivity are the practical markers. An activity that happens weekly, uses a fixed part of the premises, and could not easily be displaced by another booking is behaving like a use. One that happens occasionally and takes whatever room is free is behaving like a booking.

Ancillary sharing against a genuine dual use

The Use Classes Order puts places of worship and education in Class F1, with public halls and exhibition halls at F1(e). Day nurseries and crèches sit in Class E(f). That split is why the church and nursery example is the one that comes up most often.

If the nursery is run by the church, serves the congregation, and operates from a room within a building whose dominant character remains a place of worship, there is a reasonable argument that it is ancillary. The weight of the argument falls away as the nursery grows. Once it occupies the main hall for most of the week, employs staff unconnected with the congregation, and generates most of the traffic to the site, calling it ancillary becomes difficult.

Where neither activity is ancillary, the planning unit has two primary uses. That is a recognised position, not an anomaly. A building can lawfully have a composite or dual use, and the correct description of development is one that names both.

The practical trap is approval drift. A church that obtains permission for a hall and later hosts a full-time nursery without applying may find, years later, that the nursery has no planning status, cannot be sold with the building, and is vulnerable if a neighbour complains.

The planning unit where uses alternate

The approach from Burdle asks what the unit of occupation is, whether parts of the site are physically and functionally separate, and whether any activity is ancillary. Alternating use complicates the second limb, because the same floor area carries both activities at different times.

Where one occupier controls the whole building and lets rooms by the hour, the planning unit is normally the whole building, and the uses within it are assessed against each other. Where a nursery holds a lease over defined rooms, has exclusive use of them during its hours, and stores its equipment there permanently, there is a stronger case that it occupies a separate planning unit even if the space is shared outside its hours.

That distinction drives the application. One planning unit with two uses points towards an application describing a mixed use. Two planning units points towards a change of use application for the part occupied.

Get the description right at the start. An authority can refuse to validate an application whose description does not match what is proposed, and amending the description later is possible but awkward.

Conditions controlling hours for each use

Where a dual use is approved, conditions almost always split the hours by activity. Typical wording restricts the nursery to defined weekday hours, limits the hall use to specified evenings and weekends, and caps the number of people present for certain activities.

Negotiate the figures carefully, because conditions of this kind are hard to vary later and are the usual source of friction with neighbours:

  • Opening hours should cover arrival and departure rather than the session alone. A nursery closing at 18:00 has parents in the car park until 18:20.
  • Setup and clearing away needs separate recognition, particularly for evening events.
  • Delivery and servicing hours sit apart from operating hours, and should allow a bin collection that the authority itself schedules.
  • Occupancy caps should reflect peak rather than average, with a sensible allowance for an annual event.

A condition limiting the building to use by a named organisation is worth resisting. It frustrates sale or lease and rarely serves a planning purpose that an hours and activity condition does not already serve.

Parking demand across the week

Alternating uses are often argued to be complementary, and sometimes that is exactly right. A weekday nursery and a Sunday place of worship do not compete for spaces on the same day. That argument wins when the evidence supports it and fails when the timetables overlap more than the applicant admitted.

The evidence that settles it is a parking survey across a full week, covering weekday mornings and late afternoons, a weekday evening, Saturday and Sunday. A Parking Survey using a recognised methodology carries more weight than a count taken on one afternoon by the applicant.

Expect the highway officer to focus on the peak period rather than the average. Nursery drop-off is short, concentrated, and generates more vehicle movements per space than almost any other small use, which is why it attracts objections even where total demand is modest. A Transport Statement that models drop-off as a 30 minute peak rather than a daily total is far more persuasive.

Where overlap exists, the answer is usually a managed arrangement rather than more tarmac: staggered session times, a drop-off protocol, and a condition requiring a travel plan.

Noise and amenity at different times of day

Two uses in one building produce two noise profiles, and an environmental health officer assesses them separately.

A nursery generates outdoor play noise during the day, which is assessed against daytime amenity standards and is usually manageable with a boundary treatment and a timetable limiting outdoor sessions. A place of worship or a hall generates arrival and departure noise in the evening, amplified music during events, and car doors at 22:30, all of which are assessed against a quieter background and are much more likely to produce complaints.

Where the site adjoins housing, a Noise Impact Assessment covering both profiles against the relevant background periods is worth commissioning before the application rather than in response to an objection. And if a kitchen serves either use, the extraction route and its termination point need settling early, which is what a Ventilation and Extraction Statement addresses.

Describing the arrangement in the application

Write the description so that someone reading it in ten years knows what was permitted. Name both uses, give the class references, and state the pattern of use in the supporting statement rather than leaving it to inference.

A workable approach:

  1. Describe the development as a mixed or dual use, naming each activity and its use class.
  2. Set out the weekly timetable in the supporting statement, with hours, rooms and expected numbers for each activity.
  3. Explain which parts of the building each occupier controls and on what legal basis.
  4. State what is shared, including entrances, parking, kitchens and bin storage.
  5. Offer the conditions you can live with, rather than waiting for the officer to draft them.

That last step is the one most applicants skip. An officer given workable draft conditions usually uses them.

For readers tracing how uses are separated within one building, the note on upper floors above a shop as a separate planning unit covers the vertical version of the same question, and temporary uses and the risk of permanence deals with what happens when a short-term arrangement quietly becomes the main use.

Frequently asked questions

Does hiring out a hall create a second planning use?

Usually not. A hall hosting classes, meetings and events is simply being a hall, and those activities are what the building exists for. A second use arises where an occupier takes defined space or defined periods for an activity with its own character, staff and clientele, operating regularly enough that it could not easily be displaced by another booking.

Which use class is a day nursery in?

Day nurseries and crèches fall within Class E(f) of the Use Classes Order. Places of worship, education and public halls sit within Class F1, with public and exhibition halls at F1(e). That split is why a church hall running a weekday nursery raises a change of use question rather than a movement within a single class.

Can one building lawfully have two primary uses?

Yes. Where neither activity is ancillary to the other, the planning unit has a composite or dual use, and that is a recognised position rather than an anomaly. The application should describe both uses and name each class, so the permission on the register matches what actually happens in the building.

How should parking be evidenced for alternating uses?

With a survey covering the whole week, including weekday mornings and late afternoons, a weekday evening, Saturday and Sunday. Highway officers look at the peak rather than the average. Nursery drop-off is short and concentrated, generating more movements per space than most small uses, so modelling it as a thirty minute peak is more persuasive than a daily total.

What conditions should I expect on a dual use permission?

Separate hours for each activity, occupancy caps, and limits on delivery and servicing. Make sure opening hours cover arrival and departure rather than the session alone, and that setup and clearing away are recognised. Resist a condition limiting the building to a named organisation, since it frustrates sale or lease without serving a clear planning purpose.
