Site Generator Hire across Devon & Cornwall

We provide secure, reliable site generator hire and emergency power with a backup generator supply contract. Our site generators are used on building sites, film locations, and commercial offices in the event of shutdowns or power failures. Cornwall Generator Hire is a family owned and run business, well known and trusted by companies for their reliability and personal service. Paul and Leoni have a wide range of commercial-trade generators, including super-silenced, silenced, long-running tank options and hard–wire facilities. We provide fuel management for extended running periods to ensure your systems can continue throughout the duration of a power shortage or site requirements.

Ensure your company is not left powerless!

We offer reliable site power, delivered when and where you need it.

Site generator hire – support from start to finish

Having arrived on site, we’ll always set up and test the generator and connect any additional distribution to the machine. Before handing it over to the customer, we would provide some detailed training on how to use the equipment.

We are a family business, ideally situated on the Devon/Cornwall border, who genuinely pride ourselves on our attention to detail, genuine customer service and going that extra mile for our customers. We have over 30 years of electrical experience with a vast knowledge of temporary power solutions.

Our policy is to provide our generators with a full tank of fuel which our customers pay before delivery and by noting the consumption on collection we refund you the unused fuel via online banking within 24 hours of the generator being returned.

Need us to lay the cabling, distribution boards, and lighting no problem, we have all the kit and expertise ready to go!

The hirer is responsible for insurance to the value of equipment from the time of hire until the collection to cover costs in the eventuality of theft or damage of the equipment.

  • We provide a 24/7 rapid response service to Cornwall and Devon. If you have a power outage we can usually supply a generator within the hour
  • All our generators are excellent quality machines, quiet and fully serviced before delivery
  • Delivery and collection are charged at 45p per mile + our hourly rate of £20.00 (subject to change) from our depot to your location. The journey is calculated as two return journeys for delivery and collection. We can also offer the option of the hirer collecting from us with an appropriate vehicle (insurance required)
  • Because all of our generators are trailer mounted, they are easy to manoeuvre and having 4 x 4 vehicles, we really can deliver to the most difficult locations
  • Preferential terms can be arranged for extended hireHire Agreement
    Please read the Cornwall Generator Hire Agreement which becomes binding on the date the Job Sheet is signed.
