What’s Influencing Generator Hire Costs in 2025?


The cost of hiring a generator in 2025 is shaped by several key factors:


  • Growing Demand: With infrastructure projects expanding and climate-related disruptions becoming more frequent, demand for temporary power solutions is on the rise.
  • Sustainability Goals: The UK and ROI’s push toward net zero means more customers are opting for low-emission alternatives like HVO-fuelled or hybrid generators. These options can carry a higher upfront cost but offer long-term environmental and operational benefits.
  • Operational Costs: Factors such as fuel efficiency, transport logistics, and on-site support all contribute to the overall hire cost.
