How Much Does It Cost to Rent a Generator? 2026 Rates

Renting a generator (or genset) in Europe costs from around €40 per day for a compact site unit to over €200 per day for a 100 kVA set or larger. Price follows kVA output first, then rental duration and logistics. Fuel is almost always excluded. Below are the rate bands by output and how to choose the right size.

Indicative generator rental rates by output

Output	Typical use	Indicative day rate
5–10 kVA	Small sites, power tools, events	€40–70
20–60 kVA	Medium sites, multiple loads	€80–150
100+ kVA	Large sites, standby power	€200+

These figures cover the machine alone, fuel excluded. As with other equipment, the weekly rate is usually around four to five times the daily rate and the monthly rate around three to four weeks — the longer the rental, the lower the effective cost per day.

Choosing the right output

Sizing is the most important decision, more so than the rate itself. Add up the rated wattage of everything you need to run, then add a margin for start-up surges — motors in pumps, compressors and cranes draw considerably more current on start than their running load. An undersized generator trips under load and risks damaging connected equipment; an oversized one costs more to rent and can develop engine problems if run continuously at light load. For a step-by-step sizing method, see the generator sizing guide.

What's included and what isn't

The rental rate covers the machine and routine maintenance. These items are normally charged separately:

• Fuel (the most variable cost on long rentals)
• Delivery and collection
• Distribution boards, cables and accessories
• Additional fuel tanks for extended autonomy

On a prolonged, high-load rental, fuel can exceed the hire cost itself — always estimate expected run hours before comparing quotes on rate alone.

Renting vs a longer-term solution

For temporary requirements — construction sites, events, emergencies, seasonal demand — renting keeps cost aligned to use and removes the burden of maintenance and storage. For a permanent standby power requirement, it may be worth comparing purchase against an operating lease or finance lease, which spread the capital outlay over time. To model where the break-even sits for a specific machine, use the rent vs lease vs buy calculator.

In short

A generator costs roughly €40 per day for a compact 5–10 kVA unit to over €200 for a 100 kVA set, fuel excluded. Output class drives the rate, but correct sizing matters more: a generator that trips under load or runs constantly at low load creates more problems than the rental savings justify. Always compare all-in quotes including delivery and fuel.
