Trampoline park planning permission in an industrial shed
Indoor activity parks in large sheds are refused on impact noise through the slab and on session changeover parking. Here is the evidence an authority expects before it grants a change of use.
A trampoline park in an industrial unit nearly always needs planning permission, and trampoline park planning permission usually turns on three things: whether the local plan protects that shed for employment use, how much impact energy travels through the slab into the units either side, and whether the car park copes with a wet Saturday in half term. Design is rarely the sticking point. Noise and parking are. Sorting the evidence before you sign a lease costs far less than sorting it after.
Classifying the use and the employment land question
Indoor sport, recreation or fitness provided principally to visiting members of the public sits in Class E(d) of the Town and Country Planning (Use Classes) Order 1987, as amended in 2020. A trampoline park with soft play, a climbing wall and a small cafe is one Class E(d) planning unit, with the catering ancillary to it.
The shed itself is probably Class B8 (storage or distribution) or Class B2 (general industrial). Part 3 of Schedule 2 to the Town and Country Planning (General Permitted Development) (England) Order 2015 allows limited movement from those uses into Class E, but the storage and distribution route is capped by floorspace, and a building deep enough for a trampoline grid will be far above the cap. Check the current wording of Class I before you rely on it. In practice you are making a full application for change of use.
That makes the local plan the first document to read, not the second. Many authorities have policies resisting the loss of allocated employment land or of B2 and B8 floorspace, and an activity park is a leisure use occupying a unit the plan expected to hold jobs. The counter-argument is usually a mix of marketing evidence, the condition and configuration of the unit, and the employment the venue itself creates. Put all of that in the Planning Statement rather than leaving the officer to infer it.
Current national policy supports a strong economy and the reuse of existing buildings, and the Framework was re-issued on 17 August 2026 with policy-coded chapters in place of paragraph numbers. Cite the code from the published edition on gov.uk rather than copying a paragraph number from an older report.
Structure-borne noise through the slab
This is the issue that catches operators out. A trampoline frame transfers impact energy into the floor slab, the slab carries it laterally into the shared structure, and the neighbouring tenant hears a low-frequency thud that no amount of wall lining will stop. Where units in a terrace sit on a continuous slab, the transmission path is structural, not airborne.
Measurement and assessment usually draw on two standards. BS 6472-1 handles human response to vibration in buildings through vibration dose values. BS 4142:2014+A1:2019 covers rating levels for sound of an industrial or commercial nature affecting people in nearby dwellings, with corrections where the sound is impulsive or tonal, which repeated impacts clearly are.
Mitigation is a structural design question. Isolating the frame on resilient bearings, building a floating floor, or pulling the trampoline grid away from the party line all work, and all have to be designed before the acoustic report can conclude anything. A Noise Impact Assessment that assumes mitigation without a drawing behind it will be picked apart by the environmental health officer.
Airborne noise, music and late sessions
Glow nights with amplified music and a blacked-out hall are a different source and need their own assessment. The baseline is the measured background sound level at the nearest noise-sensitive facade, taken over the hours you actually want to trade, including Friday and Saturday evenings. Then the rating level of the proposal is compared with that background.
Practical measures that officers accept include an acoustic lobby at the entrance, a condition that external doors stay shut except for escape, a limit on external amplified sound, and a cap on fixed plant noise expressed as a level at a stated position. Agree the position in advance. A condition referencing a boundary point nobody can stand on is unenforceable and will be argued about later.
Weekend and school holiday parking peaks
Indoor leisure parking peaks run against the grain of an industrial estate, which is often an advantage. The estate is quiet on a Sunday in August and busy at 8am on a Tuesday, while the activity park is the reverse. Shared or informal overspill parking can then be part of the case, provided you have the agreement in writing.
The harder point is session changeover. Sessions typically run on the hour, so the cohort leaving and the cohort arriving overlap for ten to twenty minutes, and the car park has to hold both plus the parents who stayed. Peak demand is not average demand multiplied by a factor.
Illustrative example: a venue selling 120 jump slots per hour, with an average of 1.9 people arriving per car and roughly a quarter of adults staying on site, needs parking for the departing and arriving cohorts at the same moment, not for one of them. Those ratios are assumptions you must evidence from your own operation or from trip-rate data, not borrowed from this page.
| Evidence item | What it answers |
|---|---|
| Trip generation from a comparable site or the TRICS database | How many vehicle movements each session creates |
| Parking beat survey of the estate | Whether overspill capacity really exists |
| Swept path analysis at the access | Whether cars and HGVs can pass at changeover |
| Session timetable and capacity schedule | Where the modelled peak comes from |
Where the scheme is large or the access is constrained, the authority may ask for a Transport Assessment rather than a shorter statement. Compare the position with other publicly used leisure proposals, such as a skatepark in a public park, where the assessment focuses on pedestrian and cycle access instead.
Drop-off, queueing and the walk from the car
Industrial estate roads are laid out for articulated lorries, with wide carriageways, few footways and little lighting. Dropping children off in that setting is the detail a highway officer will press hardest on, and it is usually solved with a marked pedestrian route from the parking area to the entrance, a dropped kerb crossing, lighting to the route, and a short layby that does not block the service yard.
Fire, occupancy and what planning does not decide
Planning permission does not determine fire safety for a leisure unit. Article 9A of the Development Management Procedure Order 2015 and Planning Gateway One apply to relevant residential buildings of 18 metres or more, so they do not bite here. Fire safety comes through the Building Regulations, Approved Document B and the Regulatory Reform (Fire Safety) Order 2005.
Occupancy still shapes the application, though. The capacity you declare drives escape route widths, which drive the internal layout, which drives the parking demand and the plan you submit. Fix the capacity early and keep every document consistent with it.
Catering, extraction and odour
A cafe serving the venue's own customers is ancillary and needs no separate consent. Install a commercial fryer and a flue up the elevation and you are into odour and visual impact, which usually means a Ventilation/Extraction Statement setting out the extract rate, the filtration, the discharge height and the maintenance regime. Keep the menu modest if you want this to stay simple.
Conditions to expect, and to help draft
Expect conditions on opening hours, a maximum rating level for plant, approval of a parking and drop-off management plan before first use, restriction of amplified sound to the interior, and sometimes a cap on the number of jumpers per session. Offer the wording yourself. An operator who proposes a workable hours condition in the covering submission is far more likely to get hours they can trade on than one who leaves it to a late committee amendment.

Frequently asked questions
What use class is a trampoline park?
Indoor sport, recreation or fitness provided principally to visiting members of the public falls within Class E(d) of the Use Classes Order 1987 as amended in 2020. A trampoline park with soft play and an ancillary cafe is a single Class E(d) planning unit. Moving a large storage or industrial building into that class normally needs a full planning application rather than permitted development.
Do I need a noise assessment for a trampoline park?
Almost always, because impact energy passes through the floor slab into adjoining units and amplified music carries from the hall. Assessment is usually framed around BS 4142:2014+A1:2019 for commercial sound affecting dwellings and BS 6472-1 for vibration response, with the mitigation drawn rather than assumed. Councils normally expect a suitably qualified acoustician as the author.
How much parking does an activity park need?
Enough for two overlapping cohorts at session changeover plus staff and adults who stay on site, which is well above average demand. Work from trip-rate evidence or a comparable venue, test the busiest school holiday Saturday, and set out the session timetable so the officer can see where the peak figure comes from.
Does a trampoline park need a Fire Statement at Gateway One?
No. Article 9A of the Development Management Procedure Order 2015 and Planning Gateway One apply to relevant residential buildings of 18 metres or more in height. A single storey leisure unit is outside that regime, so fire safety is handled through the Building Regulations and the Regulatory Reform (Fire Safety) Order 2005 instead.
Will the council resist losing employment floorspace?
It may, particularly where the unit sits on an allocated employment site or the plan has a policy protecting B2 and B8 floorspace. Address it directly with marketing evidence, the condition and configuration of the building, and the jobs the venue itself supports, and set that case out in the planning statement rather than leaving it implied.
