Getting permission for a soft play centre

Indoor play falls within Class E(d), use for indoor sport, recreation or fitness principally for visiting members of the public. If the unit you are taking is already in Class E, whether it was an office, a shop or a light industrial workshop, the use needs no planning application at all. If it is a Class B8 warehouse, which most affordable units of the right size are, the change of use needs full permission.

Establish that first, because it decides whether you are making a straightforward works application or a change of use case with an employment land policy attached to it.

The use class question, settled properly

Look at the lawful use rather than the last occupier. Estate units drift, and the planning history may show a permission for light industry, a condition restricting the unit to storage, or an unauthorised change that was never regularised.

Where the position is unclear, a certificate of lawful existing use under section 191 of the Town and Country Planning Act 1990 is worth the fee. It costs less than a change of use application and, if it confirms a Class E use, it removes the application entirely.

A soft play centre with a substantial café is still principally indoor recreation, so the classification does not change. A site whose main draw is a restaurant with a play area attached is a different proposition, and where the balance tips the use becomes E(b) rather than E(d). Both are Class E, so the distinction matters less than it would elsewhere, but it changes the parking and extraction assumptions considerably.

Parking, and the weekend peak nobody surveys

This is the single most common reason a soft play application runs into difficulty.

Trip generation peaks on Saturday and Sunday mornings, during school holidays and on wet days. It is almost entirely car based because the customers are adults with small children and pushchairs. Dwell time is long, typically an hour and a half to two hours, which means turnover is low and spaces are held for extended periods. Party bookings concentrate arrivals and departures into narrow windows and add a second wave mid afternoon.

A highway officer working from a standard weekday morning count will see a quiet estate and reach the wrong conclusion in either direction. Get the survey periods agreed before the work is commissioned.

What the evidence should include:

• an occupancy survey of the estate or street on a Saturday and a Sunday morning as well as a weekday
• a trip generation estimate for indoor play drawn from an established database rather than from a comparable use
• a note on the overlap with the other occupiers on the estate at those times
• a drop-off arrangement that does not require reversing across a pedestrian route
• pushchair accessible parking close to the entrance, and somewhere to leave pushchairs inside

A parking survey run to the Lambeth methodology is designed for residential overnight demand and is not the right tool here. What you want is a daytime occupancy count across the periods that matter, and a Transport Statement that explains the pattern rather than applying a floorspace standard.

Noise from occupants, which is not plant noise

Children in a play frame generate sound that BS 4142 was never designed to assess. That standard deals with sound of an industrial and commercial nature, and applying its rating penalties to shrieking is the sort of thing that gets a report picked apart by an environmental health officer.

Split the assessment. Fixed plant, meaning the air handling, the refrigeration and any kitchen extract fan, is assessed under BS 4142 against the measured background level. Occupant noise inside the building is a matter of building fabric performance and containment, and the practical questions are whether the roller shutter or entrance doors will be open in summer, whether any windows open onto a residential boundary, and what the internal levels will be at the party wall.

External occupant noise is the third element: the car park, the doors, and any outdoor play area. On an estate surrounded by other commercial units this is rarely an issue. Adjoining residential property changes the calculation completely, and an outdoor element next to gardens will usually need a condition restricting its hours.

A Noise Impact Assessment that separates those three, and that names the plant before the assessment is written, is what an environmental health officer will accept.

Catering, extraction and refuse

Almost every soft play centre has a kitchen, and the kitchen is where the works application lives. A commercial extract system on the rear elevation is development, and on an industrial unit it usually means a duct rising above eaves level with a fan and a termination point.

The planning issues are odour dispersal, the noise of the fan, and the visual effect of the duct. A Ventilation and Extraction Statement setting out the cooking type, the extract volume, the filtration and the discharge height and velocity answers all three, and it is worth preparing before the kitchen equipment is ordered because the specification drives the duct size.

Refuse is the other item. Food waste, packaging and nappies in volume, with a collection frequency to match, and a bin store that is screened, ventilated and within reasonable drag distance of the collection point. Work from the council's own waste storage guidance.

Fire, occupancy and what belongs at planning stage

Occupant capacity and means of escape are building regulations matters under Approved Document B, together with the fire risk assessment duties that apply once the business is operating. They are not usually planning matters, and a planning application does not need a fire strategy.

The exception is narrow. A Fire Statement is required at Planning Gateway One only for relevant buildings under the Building Safety Act 2022 framework and Article 9A of the Development Management Procedure Order 2015, which is aimed at higher risk residential buildings rather than at a single storey leisure unit. If someone tells you a soft play scheme needs one, check the definition before you commission it.

What does belong in the planning submission is the layout, because escape routes and the mezzanine arrangement shape the internal plan and therefore the parking demand and the servicing. Where the fit-out includes a mezzanine, our note on mezzanine floors and when installation needs permission sets out when that is development in its own right.

The employment land argument

Most industrial estates carry a local plan policy resisting the loss of employment floorspace, and leisure use is not employment use for that purpose.

The answer is rarely that the play centre is a good thing. It is that the unit is unsuitable for continued employment use for reasons intrinsic to the building, supported by marketing evidence gathered on the terms the policy specifies. Eaves height, yard depth, access width, floor loading and position behind housing are the arguments that work. An Employment Land Assessment covering the local supply, the unit's characteristics and the marketing record is the document that carries it.

Read the policy before you start marketing. Evidence gathered on the wrong terms has to be repeated, and a marketing period restarted in February costs a summer.

This is general guidance rather than legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
