🔌 **Most food trucks bring their own power.** Check the listing and confirm the exact requirements with the supplier before your event.

Power is one of the practical details worth checking when you book a food truck. Many UK food trucks are self-sufficient, but some need access to a mains power supply at the venue.

A quick conversation with the supplier and your venue is usually all it takes. This guide explains the common setups, the questions to ask and what to plan before the truck arrives.

Do food trucks need an external power supply?

Often, no. Food trucks are designed to work in places where mains electricity may not be available. Depending on the truck, power may come from LPG, an onboard generator, batteries or a combination of these.

Burners, grills, fryers and ovens are often gas-powered, taking care of the truck's biggest energy demand.

LPG for cooking

A generator can run lighting, refrigeration, extraction fans, coffee machines and till systems.

Onboard generator

Some smaller trucks use leisure batteries or inverters for LED lighting and basic electronics.

Battery or inverter

If the truck needs venue power, the supplier should tell you the required current, phase, connector and number of outlets. These are the three supplies you're most likely to encounter.

⚠️ **Do not guess from the socket size alone.** Confirm the exact connector, current and phase with the supplier and venue. If either side is unsure, use a qualified electrician.

This is the normal 3-pin socket found in UK homes and venues. Some operators only need one or two 13A sockets for equipment such as a fridge, lighting or a coffee machine.

Ask how many sockets are needed and whether the supplier requires a dedicated circuit. A socket being available does not automatically mean the circuit can safely handle a sustained high load alongside other equipment.

A 16A commando connection is a step up from a standard plug. Blue 3-pin connectors are normally single-phase, while red 5-pin connectors are normally three-phase.

Confirm the colour and pin configuration with the supplier, then ask the venue whether it has an exact match. If it doesn't, tell the supplier early so they can confirm a safe alternative.

A 32A supply is usually needed only by larger trucks with commercial ovens or several high-draw appliances. These connections are more common at commercial premises and established event venues than at private homes.

As with 16A supplies, the supplier and venue must agree the exact connector and setup. If the venue cannot provide it, ask whether the truck can use a suitable generator or a different configuration.

Extension leads and outdoor electrical safety

Most operators who need mains power bring their own lead. Ask how long it is and tell them the distance from the socket to the truck's pitch. Plan the cable route so it stays away from guests, vehicles and standing water.

Extension leads should be correctly rated, suitable for the conditions and fully unwound. Do not overload them or plug one extension lead into another.

For larger or more complex events, the HSE recommends planning mains access, generator use, weather protection and cable routing as part of the temporary electrical setup.

What if the food truck brings a generator?

A generator usually means the truck can operate without venue power, but there are still two practical points to check.

Modern generators can be relatively quiet, but they still hum. For a garden party or ceremony, ask whether it can sit away from the main gathering area.

Noise

Generators need safe ventilation and separation from guests. Check whether the venue restricts generators, fuel storage or operating hours.

Placement and restrictions

Food truck power checklist for your venue

For most bookings, power is straightforward: the truck arrives with everything it needs. If mains power is required, confirm the exact supply with both the supplier and venue before the day.
