Guide to Power and Electrics for Marquees
This guide explains how electrical power is used in marquees and what needs to be planned in advance.
It covers power sources, typical electrical loads, and safety considerations for temporary event setups.
Do marquees come with power?
Marquees themselves do not generate power.
A suitable external power source is required to run lighting, heating, or any electrical equipment inside the marquee.
Power is most commonly supplied from a nearby building, venue socket, or temporary power source.
It is important to confirm what power is available before booking.
Common electrical items used in marquees
The most common electrical items used during marquee hire include:
- Lighting supplied with the marquee
- Marquee Heating
- Music or DJ equipment
- Catering equipment such as hot plates or urns
Each item adds to the overall electrical load and must be considered when planning power supply.
Power load and capacity
Standard domestic sockets have limited capacity.
Running multiple high-load items from a single socket can cause power trips or overheating.
You should identify all equipment that will require power and confirm this in advance.
Do not assume that all items can be run from one supply.
Use of extension leads
Extension leads must be suitable for outdoor use and routed safely to avoid trip hazards.
Leads should not be run through standing water or across walkways where possible.
For safety reasons, do not connect personal electrical appliances to our power supply without prior approval.
This helps prevent overloading and unsafe connections.
Lighting inside a marquee
Lighting is typically used to provide general visibility rather than decorative effects.
For evening events, lighting should be sufficient to cover walkways, seating areas, and exits.
Lighting layout should be considered alongside furniture placement.
Refer to the Furniture Layout Guide for Marquees when planning internal layouts.
Heating and electrical planning
Heating places a significant load on the power supply.
If Marquee Heating is required, confirm power availability early in the planning process.
Heating guidance is covered in more detail in the Guide to Heating a Marquee.
Weather and electrical safety
Wet weather increases electrical risk if planning is poor.
All electrical connections should be kept off the ground and protected from rain.
For wet conditions, review the Wet Weather Contingency Planning Guide and the
Guide to Weather Proofing Your Marquee.
What to confirm before your event
- What power source will be used
- How many electrical items will be connected
- Whether heating is required
- Safe routing for extension leads
- Protection from rain and foot traffic
