Outdoor events offer something indoor venues cannot: fresh air, open skies, and the freedom to create a space from scratch. They also present challenges that indoor organisers never face — weather, power, sanitation, noise, and council permissions. This guide covers the practical logistics of running outdoor events in the UK.
Temporary Event Notices and premises licences
If your outdoor event involves the sale of alcohol, regulated entertainment (live or recorded music, for example), or late-night refreshment (hot food or drink after 11pm), you need a licence.
Temporary Event Notice (TEN)
A TEN is the most common route for one-off outdoor events. It allows licensable activities for up to 499 people at any one time. Key rules:
- You must be aged 18 or over to apply.
- Give the licensing authority, the police, and environmental health at least ten working days' notice. Late TENs (minimum five working days) are allowed but can be objected to by police or environmental health with no right of appeal.
- A single premises can have a maximum of fifteen TENs per calendar year, and the total number of days covered cannot exceed 21.
- Each personal licence holder can give fifty TENs per year; non-licence holders can give five.
- The fee is twenty-one pounds per notice.
If the police or environmental health object to a standard TEN, a hearing is held by the licensing committee. For late TENs, an objection means automatic refusal with no hearing.
Premises licence
For larger events (500+ capacity) or recurring events on the same site, you need a premises licence. This is a more involved process that includes a formal application, public consultation period, and potentially a hearing. The application fee depends on the rateable value of the premises, and the process typically takes eight to twelve weeks.
If your outdoor venue is on private land, you may also need the landowner's written permission and potentially planning consent from the local council.
Weather contingency planning
British weather is reliably unreliable. Even in summer, rain, wind, and sudden temperature drops are entirely normal. A robust weather plan is essential for any outdoor event.
Before the event
- Monitor forecasts — use the Met Office or a specialist weather service. Start monitoring at least a week out, with more frequent checks from 48 hours before.
- Define your trigger points — at what wind speed do you take down signage? At what rainfall intensity do you activate your mud plan? At what temperature do you provide shade or heating? Write these down and share them with your team.
- Communicate with attendees — advise attendees to bring waterproofs and wellies. It sounds obvious, but a simple "dress for the weather" message in your pre-event communication prevents complaints and improves the experience.
Wind
Wind is the most dangerous weather risk at outdoor events. Unsecured structures, marquees, signage, and inflatables can become projectiles. Key precautions:
- All temporary structures must be properly ballasted or staked. Speak to your marquee supplier about the expected wind load.
- At sustained wind speeds above 35-40 mph, most marquee manufacturers recommend dismantling or closing sided structures.
- Inflatables must be deflated and secured at wind speeds above 24 mph (as per the HSE's guidance on inflatable devices).
- Elevated equipment (speaker stacks, lighting towers) must be properly weighted and guyed.
Rain
Rain turns grass into mud, makes surfaces slippery, and makes everyone miserable if there is nowhere to shelter. Mitigations include:
- Trackway matting on main pedestrian routes and high-traffic areas.
- Straw bales on grass areas prone to churning.
- Covered areas for queues, food service, and at the entrance.
- Drainage assessment of the site — low-lying areas will flood. Do not place stages, production, or electrical equipment in natural drainage channels.
Marquees and shelters
Marquees are the backbone of most outdoor events, providing shelter, defined spaces, and weather protection.
- Frame marquees — freestanding aluminium frames with PVC covers. No internal poles, so the interior space is fully usable. Best for events needing clear sightlines and maximum floor space.
- Traditional pole marquees — supported by internal poles and tensioned guy ropes. Attractive and atmospheric, but the poles reduce usable space and the guy ropes extend the footprint. Better suited to garden parties and weddings than events with staging.
- Stretch tents — flexible fabric structures that can be configured in various shapes. Visually striking and work well for open-sided coverage over bars, dining areas, and chill-out zones.
When hiring marquees, specify your requirements clearly: dimensions, sides (open or closed), flooring (grass, carpet, or hard floor), lighting, and heating. A marquee in April without heating is an unpleasant experience. Budget for proper installation and dismantling — marquees must be installed by competent crews, not improvised.
Generators and power
Most outdoor sites have no mains power, which means generators. Power planning for outdoor events requires careful calculation:
- Calculate your total load — PA, lighting, food vendors, bars (fridges, ice machines), charging points, and production equipment. Add a twenty per cent buffer for spikes and unanticipated demand.
- Generator sizing — generators are rated in kVA (kilovolt-amperes). A rough conversion: 1 kVA provides approximately 0.8 kW of usable power. A small event might need a 20 kVA generator; a festival stage with full production might need 100 kVA or more.
- Fuel — a standard diesel generator burns approximately 2 to 4 litres per hour per 10 kVA of load. Plan your fuel supply accordingly and arrange refuelling for multi-day events.
- Noise — generators are loud. Position them as far from the audience as cable runs allow. Silenced (canopied) generators are more expensive but significantly quieter. If the event has quiet periods (acoustic sets, speeches), generator noise becomes very noticeable.
- Safety — generators must be earthed, protected by RCDs, and operated by competent personnel. Refuelling must happen when the generator is off. Fuel storage must comply with DSEAR regulations. Your hire company should handle all of this, but check.
Portable toilets
The number of toilets you need depends on attendance, event duration, and whether alcohol is being served (alcohol significantly increases usage). The Event Safety Guide recommends:
- Without alcohol: one toilet per 100 females and one toilet per 500 males plus one urinal per 150 males.
- With alcohol: one toilet per 75 females and one toilet per 400 males plus one urinal per 100 males.
At least five per cent of all toilet provision should be accessible units for wheelchair users and people with disabilities.
Portable toilet logistics to plan for:
- Servicing — for events lasting more than eight hours, arrange mid-event servicing (restocking toilet paper, emptying tanks, cleaning).
- Positioning — close enough to be convenient, far enough from food areas to be hygienic. Well-lit and clearly signposted.
- Handwashing — standalone handwash stations or hand sanitiser stations adjacent to the toilet block. This is a food hygiene and public health requirement, not a nice-to-have.
Parking and access
If attendees are driving to your outdoor event, you need a parking plan. Grass car parks work in dry weather but become bogs in wet conditions. Consider:
- Surface — hard standing is ideal but rare at rural outdoor sites. Temporary trackway on main routes prevents vehicles getting stuck. Budget for a tow vehicle or tractor if grass parking is your only option.
- Capacity — allow roughly 12 to 15 square metres per car (including manoeuvring space). A thousand attendees with an average of 2.5 people per car need parking for 400 vehicles — that is approximately 5,000 square metres of car park.
- Stewards — trained parking stewards direct traffic, maximise capacity, and prevent gridlock. Without them, people park wherever they want and create chaos.
- Signage — directional signage from main roads to the site entrance, and within the site from parking to the event area.
- Emergency access — ambulances and fire engines must be able to reach the event site at all times. Maintain clear emergency routes that are never blocked by parked vehicles.
Noise regulations
Outdoor events generate noise that carries far beyond the site boundary. Noise complaints from local residents can result in enforcement action, licence conditions, or refusal of future TENs.
- Noise management plan — required for most licensed outdoor events. It should specify sound levels, monitoring locations, music curfew times, and the procedure for handling complaints.
- Sound monitoring — position sound level meters at the nearest noise-sensitive premises (residential properties) and at the mixing desk. Assign someone to monitor levels throughout the event.
- Music orientation — point speakers away from residential areas wherever possible. The stage orientation has a significant impact on off-site noise levels.
- Curfew — most outdoor event licences specify a music curfew, typically 11pm on weekdays and midnight on weekends. Respect it. Exceeding the curfew is the fastest way to lose your licence for future events.
- Liaison — notify neighbouring residents in advance. Provide a contact number for noise complaints on the day. A proactive approach to community relations goes a long way.
Council permissions and site assessments
Depending on the size and nature of your outdoor event, you may need additional permissions from the local council beyond the TEN or premises licence:
- Event notification — many councils have a Safety Advisory Group (SAG) that reviews outdoor events. Submit your event management plan, risk assessment, and site plan for their review.
- Road closures — if your event requires temporary road closures, apply through the council's highways department well in advance (typically 12 weeks minimum).
- Land use — events on public land (parks, commons) need permission from the landowner, which is often the council itself.
- Waste management — plan for waste collection and site clearance. Many councils require a waste management plan for licensed events.
Outdoor events are rewarding but logistically intensive. Start planning early — twelve months in advance for larger events — and build contingency into every element. When you sell tickets through Tickts, include clear arrival instructions, parking information, and weather guidance in the event description. Attendees who arrive prepared have a better time, and fewer of them end up at your information point asking where they can buy an umbrella.
