Running events from a warehouse unit

A warehouse hired out for parties, weddings or club nights is in most cases a material change of use, and the warehouse events venue planning permission question is usually answered before anybody has thought about it. Class B8 storage and distribution is a quiet, low-trip, daytime use. An events venue brings several hundred people, amplified music and a 2am dispersal to a unit built for forklifts.

The temporary event notice route does not fix this. A notice under the Licensing Act 2003 authorises licensable activities. It says nothing about planning, and a run of notices across a year is itself evidence that the planning use has changed.

Storage use against an events use

Class B8 covers storage or distribution, including open-air storage. The planning characteristics that go with it are modest staff numbers, heavy goods vehicle movements concentrated in working hours, almost no visitor parking and very little evening activity.

An events use changes every one of those. The relevant comparison a planning officer makes is not of building fabric but of planning effects: trip generation and its timing, parking demand, noise, hours, waste, and the relationship with neighbours who have grown used to a building that empties at six.

The test is whether the change is material, and on these facts it is. A single charity event once a year is a different matter from a venue operating most weekends, and the line between them is a question of fact and degree rather than a rule.

One widely misunderstood point: the permitted development right allowing temporary use of land for up to 28 days a year applies to land, not to buildings. It does not authorise events inside a warehouse. Where the events are in a yard or a field, that right may help, subject to its own limits and exclusions.

Where the use becomes sui generis

Since the 2020 changes to the Use Classes Order, several assembly and leisure uses sit outside the classes entirely. Concert halls, live music venues, nightclubs, dance halls, cinemas and bingo halls are sui generis.

What that means for a mixed events offer is that the precise nature of the use decides the class, and most genuine events venues end up sui generis. An indoor sport, recreation or fitness use would fall within Class E. A hall or meeting place used principally for the local community can fall within Class F.2. A commercial venue hired for weddings and club nights fits neither.

Describe the use carefully in the application. "Change of use from Class B8 to events venue (sui generis)" invites a sensible assessment. A vague description such as "flexible community and leisure use" produces a permission nobody can interpret and conditions nobody can enforce. The piece on escape rooms and experience venues in retail units covers the same classification question in a different setting.

Consider asking for a mixed use where storage continues alongside events, because it preserves the fallback position and can be conditioned to limit event frequency.

Temporary event notices and their limits

A temporary event notice allows licensable activities at premises for a limited period. The headline limits are a maximum duration of 168 hours per event and fewer than 500 people on site at any time including staff, with an annual cap on the number of notices and total days per premises that the licensing authority publishes.

Three things follow.

A notice is not planning permission, and using notices repeatedly is evidence that the use has changed rather than a defence against the allegation.

The 500-person limit is a hard ceiling. A warehouse capable of holding 800 cannot use the notice route for its actual capacity, so a premises licence is needed, and that application brings the same hours, noise and dispersal questions into the licensing arena.

And the notice can be objected to by the police or environmental health on the licensing objectives, so an operator who has already annoyed the neighbours will find the route closing.

Noise breakout from a metal clad building

This is the technical issue that decides most of these applications, and it is worse than operators expect.

Profiled metal cladding and single-skin roofs offer poor sound reduction, particularly at the low frequencies that carry amplified music. A building that looks solid can leak bass to residential property several hundred metres away, and the sound escapes through roof lights, personnel doors, ventilation louvres and the eaves detail as much as through the cladding itself.

An acoustic case needs to do four things. Establish the existing background sound level at the nearest sensitive receptors, measured over a representative period including the proposed operating hours, typically late evening and night. Predict the breakout level from the proposed music level and the building's sound reduction performance, element by element. Compare the result against the relevant criteria, using the industrial and commercial sound standard for plant and the specific guidance for music noise where amplified entertainment is proposed. And set out mitigation with the performance each measure delivers.

Mitigation that works includes an acoustically lined inner skin or a room-within-a-room, lobbied entrances with self-closing doors, sealing or replacing roof lights, attenuated ventilation, and a noise limiter set and sealed in agreement with environmental health. Mitigation that does not work includes a promise to keep the volume down and a request that patrons leave quietly.

A Noise Impact Assessment is a report type where councils expect a suitably qualified author and professional review is strongly advised. Submit it with the application rather than offering it by condition, because an environmental health officer who has not seen the numbers will recommend refusal.

Dispersal, taxis and amenity

Industrial estates are usually poorly served by public transport at night, which means cars and taxis.

The questions to answer are how many parking spaces are available and whether they are in the operator's control, where taxis will wait without blocking the estate road, how pedestrians reach the nearest road with a footway, and what happens at closing time when several hundred people leave within 20 minutes.

A dispersal plan is the document for this. It should cover staggered closing, staffed exits, a marshalled taxi area away from the nearest housing, signage directing patrons away from residential streets, and a telephone number that is answered during events. Where trip generation is substantial, a Transport Statement quantifying the arrival and departure profile is proportionate.

Waste is a smaller but real issue, because an events use generates glass and food waste on a pattern the estate's collection arrangements were not designed for, and glass collections at 7am on a Sunday cause their own complaints.

Capacity, escape and safety

Planning does not determine capacity, but capacity determines much of the planning case, so the two have to be settled together.

Escape route width, travel distances and the number of exits under the building regulations set a maximum occupancy, and a warehouse designed for storage often has fewer and narrower exits than an assembly use needs. A fire risk assessment under the fire safety order is required for the operating premises, and the licensing authority will expect to see it.

Get the occupancy figure established early by a competent fire engineer or building control, because the planning application, the licensing application and the business model all depend on it. Where structural alterations are needed to create exits, those may themselves need permission.

Conditions to expect and to shape

Rather than resisting conditions, propose workable ones. The versions that get granted usually include:

1. A maximum number of events per calendar year, and a maximum number per month, with a definition of what counts as an event.
2. A maximum number of patrons on site at any time, tied to the fire capacity figure.
3. Finish times for amplified music and for the premises, with the music finishing earlier than the closing time to allow managed dispersal.
4. A noise limiter installed and set in agreement with the authority, with a requirement that it is not altered.
5. All doors and windows to be kept closed during amplified music except for access and egress.
6. A dispersal and management plan to be approved and then adhered to, with a named contact.
7. Restrictions on external amplified music and on use of the yard after a stated hour.

A note worth making: conditions limiting event numbers are enforceable precisely because they are countable, and an operator who exceeds them is easy to catch. Negotiate a number you can live with rather than accepting one you will breach. The rural equivalent of this whole exercise is covered in the article on wedding and events venues in rural buildings.
