Soft play centres: use class, noise and parking in planning

A commercial soft play centre normally falls within Class E(d) of the Town and Country Planning (Use Classes) Order 1987 as amended in 2020, which covers indoor sport, recreation or fitness provided principally to visiting members of the public. That classification is what decides whether you need soft play centre planning permission at all. Moving into a former shop or office already in Class E is usually not development. Moving into a warehouse or a general industrial unit almost always is.

Get the class right before you sign a lease. The rent on an industrial unit looks attractive until you price in a nine-month application and a noise assessment.

How soft play is usually classified

The 2020 amendment broke up the old assembly and leisure class and put indoor recreation into E(d). Soft play, trampoline parks, climbing centres and indoor play barns generally sit there, alongside gyms and dance studios.

Because changes within Class E are not development, a unit lawfully used as a shop, a café, an office, a clinic or a light industrial workspace can become soft play without a planning application. That single point decides most soft play site searches. The caveat is that the existing lawful use must actually be inside Class E, and conditions on an earlier permission can restrict the use of a particular building regardless of the Order. Read the planning history before relying on the flexibility, because a condition tying a unit to retail use overrides the class.

Some councils take the view that a large play centre with an extensive catering offer, parties and an entrance charge has moved beyond E(d) and become sui generis. That argument is more common for trampoline parks than for toddler soft play. Where there is doubt, an application for a lawful development certificate for a proposed use under section 192 of the Town and Country Planning Act 1990 settles it. The boundary between E(g) workspace uses and other classes is tested the same way, which is covered in more detail in light industrial and office uses inside Class E(g). This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.

Party rooms and the catering element

A café serving parents while their children play is ancillary to the main use and needs no separate consent. Party rooms are the same. The planning unit stays as one soft play use.

The line is crossed when the catering starts to function independently. A café with its own street entrance, its own opening hours and customers who never enter the play area is a separate use in Class E(b), and that matters because it changes the parking and servicing picture rather than because E(b) and E(d) sit in different classes. Hot food sold for consumption off the premises is sui generis and does need permission.

Any commercial kitchen brings extraction with it. If you are installing a canopy and a duct, the council will want to see the termination point, the odour control and the acoustic treatment of the fan. A short Ventilation and Extraction Statement covering duct route, discharge height, filtration and attenuation is normally enough for a small servery, and it heads off a condition requiring details to be approved before use starts.

Taking a warehouse or industrial unit

Part 3 of Schedule 2 to the GPDO 2015 does not give you a route from B2 general industrial or B8 storage and distribution into Class E(d). The permitted changes out of those classes run into E(g) or between B2 and B8, as explained in general industrial to storage and distribution. So a soft play centre in a warehouse is a full change of use application.

Expect three lines of resistance.

1. Loss of employment land. If the unit sits in an allocated employment area or an industrial estate protected by a local plan policy, you need marketing evidence or an argument that the use is employment-generating in its own right. Soft play centres do employ people, and that point is worth making with staff numbers.
2. Highway safety and servicing. Estate roads designed for articulated deliveries are not designed for 40 cars arriving between 9.45am and 10am on a Saturday with toddlers getting out of them.
3. Amenity of neighbouring industrial occupiers. The agent of change principle runs both ways, and a council can refuse a sensitive use next to a 24-hour operation.

The counter-argument is usually availability. Few high street units have the 5 metre clear internal height a two-tier play frame needs, and fewer still have level access and a car park. Say that in the planning statement rather than leaving the officer to work it out.

Noise breakout and the acoustic case

Children's play noise is tonal, impulsive and entirely unpredictable, which makes it harder to assess than plant noise. For the mechanical services you use BS 4142:2014+A1:2019 and compare the rating level with the background sound level at the nearest residential facade. For the activity noise itself there is no single standard, so acousticians usually model internal levels, apply the sound reduction index of the building envelope, and check the resulting level at the nearest window against the internal guideline values in BS 8233:2014.

The practical measures are familiar. Keep the main doors on a self-closing acoustic lobby. Provide mechanical ventilation so the doors and roof lights never need to be opened for cooling. Treat the inside of the envelope rather than only the party wall, because a profiled metal warehouse roof is the weak element. And locate the toddler area away from the elevation facing housing.

A Noise Impact Assessment should be prepared by a suitably qualified acoustician. Councils usually expect a member of the Institute of Acoustics, and professional review is strongly advised even where a draft gives you the structure.

An illustrative case: a 900 m² unit on the edge of an industrial estate, 35 metres from the rear gardens of a terrace. The acoustic model showed the roof as the dominant transmission path. Lining the underside of the deck and sealing the rooflights brought the predicted level below the measured background, and the council conditioned the lining before first use rather than refusing.

Parking at the weekend peak

Soft play demand peaks when nothing else on an industrial estate is operating, which can help. It also peaks sharply. Sessions and parties concentrate arrivals into fifteen-minute windows, and parents park for 90 minutes rather than 20.

Build the transport case on session capacity rather than floorspace. State the number of concurrent sessions, the maximum occupancy per session, the party room capacity, the staff shift pattern and the turnaround time, then derive trips from that. A Transport Statement is the right document for a scheme of this scale, with trip rates from the TRICS database and a survey of on-street conditions if overspill is likely.

Where the council's standards are expressed per 100 m² of leisure floorspace, point out that gross internal area includes the double-height void above the frame and overstates the demand.

Occupancy, escape and what planning does not cover

Maximum occupancy, travel distances, final exit widths and the fire strategy are Building Regulations matters under Approved Document B, not planning ones. Planning officers will nonetheless ask for your occupancy figure, because it drives parking, servicing and noise. Give the same figure to both and keep it consistent.

Licensing is separate again if you plan to sell alcohol at parties or provide regulated entertainment.

Conditions you should expect

Opening hours are the first condition and the one worth negotiating hardest, because a 6pm closure kills after-school trade. Ask for 9am to 8pm and expect to settle.

Other conditions commonly imposed on consents of this kind include a limit on noise from fixed plant expressed relative to background, a requirement that doors and windows be kept closed during operation other than for access, approval of extraction details before the use starts, a delivery and servicing restriction, a parking management plan for party drop-off, and a cap on the maximum number of people on the premises at any one time.

Read each one against how you actually trade. A condition requiring all deliveries before 8am is unworkable for a business whose staff arrive at 9am, and it is much easier to argue at the draft condition stage than through a later section 73 application.
