A dark catering tent, a silent PA system or toilets without lighting can change the mood of an event in minutes. Event generators provide the temporary power that keeps the practical details working properly, from a small wedding reception to a busy public festival. Getting the right generator is not simply about choosing the biggest unit available – it is about matching power, fuel, access and safety arrangements to the event you are actually running.
At Local Toilet Hire Ltd, we help organisers source dependable temporary infrastructure from one experienced, family-run supplier. That means less time coordinating separate deliveries and more confidence that essential facilities will be ready when your guests, crew and suppliers arrive.
What event generators can power
A generator is often the quiet backbone of an outdoor event. It can supply power where there is no suitable mains connection, where the existing supply cannot handle the demand, or where a backup is needed for critical equipment.
Typical requirements include lighting for marquees, pathways and car parks; catering equipment; bar areas and card machines; sound and stage production; refrigeration; site offices; and power for toilet units or luxury toilet trailers. The exact demand depends on the specification of every appliance, not just the size of the crowd.
A garden party with a few strings of lights and a small bar has a very different requirement from a corporate event with amplified music, food traders and illuminated toilet trailers. Equally, a generator that is suitable during daylight hours may not be enough once evening lighting, heating or additional catering equipment is switched on.
Choosing the right size event generator
The first job is to build an honest list of everything that needs power. Include the obvious items, but do not overlook refrigeration, water pumps, phone charging, decorative lighting, security equipment and supplier equipment that may arrive later in the planning process.
Each item has a running load, usually measured in watts or kilowatts. Some equipment, particularly refrigeration and motors, can draw a higher surge of power as it starts. That is why adding together the figures on a few labels is not always enough. A sensible allowance for start-up loads and planned additions protects against tripped supplies and last-minute scrambling.
It is usually better to have appropriate headroom than to run a generator constantly at its limit. However, oversizing by a large margin can create unnecessary hire and fuel costs. The right answer depends on your equipment list, event duration and whether loads will operate at the same time.
Tell your hire supplier what you are powering, how long the event runs, and whether there are particular high-demand periods. A clear brief makes it easier to recommend a suitable generator and distribution set-up. If your plans change, update the supplier before delivery rather than hoping the original provision will cover an expanded bar or an extra food vendor.
Think about single-phase and three-phase power
Many smaller event applications use single-phase power, while larger production, catering and commercial equipment may need three-phase power. The distinction matters. A generator can have enough overall capacity but still be unsuitable if the output does not match the equipment connection.
Your production company, caterer or electrician should be able to confirm their electrical requirements. Sharing that information early avoids adapters, cables and capacity assumptions becoming a problem on event day.
Location, access and noise matter
A generator needs a practical, secure place to operate. It should sit on level, stable ground with safe access for delivery and refuelling. The location must allow adequate ventilation and should be kept away from entrances, busy pedestrian routes and areas where guests could interfere with equipment or cabling.
Noise is another important consideration. Generators are designed for work, but their impact is greater when placed beside a wedding ceremony, acoustic performance or dining area. Positioning it behind service areas or at a sensible distance can make a meaningful difference. For events with tight noise restrictions, discuss this at the quote stage rather than treating it as an afterthought.
Cable routes need the same care. Cables should be protected where they cross walkways or vehicle routes, with suitable ramps where required. Do not run loose cables through crowds, across fire exits or through areas likely to become muddy. A tidy power plan is safer, easier to manage and looks more professional.
Plan fuel around the real running time
A generator may need to operate for more hours than the public event itself. Build, sound checks, catering preparation, supplier set-up and breakdown can all extend the power requirement. A one-day event can easily create a longer operating window than expected.
Fuel planning should take account of the generator load, running hours and any overnight requirement. If the unit needs refuelling, that should be agreed in advance so there is no interruption to lighting, refrigeration or essential facilities. Keep fuel arrangements managed by the right people and follow the supplier’s operating guidance.
For multi-day festivals, sporting events and public attractions, it can be worth separating essential and non-essential loads. This approach helps keep critical services running if a problem develops elsewhere in the system. It also makes it easier to monitor where power is being used.
Event generators work best as part of one site plan
Power is only one part of a successful temporary event site. Toilet placement, disabled access, fencing, delivery routes, waste servicing, lighting and vehicle movements all need to work together. When each element is ordered in isolation, the site can become awkward to operate before the first guest arrives.
For example, toilet units need sensible access for servicing and enough nearby lighting after dark. Catering operations need a clean, safe power route. Temporary fencing may be needed to guide queues, define staff-only areas or protect equipment. A generator location that seemed convenient on paper may be unsuitable once all of these requirements are mapped out.
Using one supplier for several temporary hire requirements can reduce unnecessary handovers and conflicting delivery times. It also gives you one point of contact if plans move, access changes or weather affects the ground conditions. That practical coordination is particularly valuable for events on fields, estates, sports grounds and temporary venues.
Do not leave power to the final week
Event organisers are often busy confirming guests, suppliers and timings, so infrastructure can slip down the list. Yet generators, toilets and fencing need early thought, especially in peak wedding, festival and summer event periods. Earlier booking gives more time to confirm access, calculate demand and arrange the right equipment.
Last-minute hire is still possible in many cases, but availability and delivery options naturally depend on location, stock and notice. A quick conversation is always worthwhile if your plans are urgent. Provide the event date, site postcode, access details, expected attendance, running hours and a list of electrical equipment to get a useful quote quickly.
Before confirming, ask what is included with the generator, whether cables and distribution are required, how refuelling will be handled, and who is responsible for connecting specialist equipment. Clear responsibilities prevent assumptions on the day.
Service you can rely on when guests are arriving
Temporary power should not feel like a gamble. A reliable hire partner will help you consider the practical questions before delivery, provide equipment suited to the job and communicate clearly about timing and access. That is especially important when an event has a fixed opening time and no room for delays.
When comparing suppliers, look beyond the headline hire price. Consider experience, response times, nationwide delivery capability and independent feedback. Our Trustpilot reviews give customers a useful view of the service standards we work hard to maintain, and you can check our current Trustpilot score alongside recent customer feedback before making a decision.
Whether you need one generator for a private celebration or a coordinated package for a larger public event, the goal is the same: dependable facilities that let guests focus on the occasion rather than the logistics.
