In today’s world, a reliable source of power is essential for both residential and industrial purposes. Generators play a crucial role in ensuring a continuous and stable supply of electricity. 

When considering generator hire, two main options come to mind: diesel generators and gaseous generators. Each type has its own set of advantages and disadvantages. In this article, we will delve into the pros and cons of diesel generator hire versus gaseous generator hire, helping you make an informed decision about which option best suits your power requirements.

Diesel Generator For Hire


  • Fuel Efficiency: Diesel generators are known for their high fuel efficiency. They consume less fuel compared to gaseous generators, making them a cost-effective choice in the long run.
  • Durability and Reliability: Diesel engines are renowned for their robustness and longevity. They are designed to withstand heavy usage and perform reliably for extended periods of time.
  • Low Maintenance: Diesel generators require less maintenance compared to gaseous generators. With fewer moving parts and no spark plugs or wires to replace, diesel generators are easier to maintain and have lower maintenance costs.
  • Availability: Diesel fuel is readily available at fuel stations, making it more accessible than other fuel sources. This ensures a constant supply of fuel for your generator, even during emergencies or natural disasters.


  • Higher Initial Cost: Diesel generators typically have a higher upfront cost compared to gaseous generators. However, the long-term savings in fuel consumption and maintenance costs often outweigh the initial investment.
  • Noise and Emissions: Diesel generators tend to produce more noise and emissions compared to gaseous generators. While newer models are designed to be quieter and more environmentally friendly, noise and emissions can still be a concern in certain applications.

Gaseous Generator For Hire


  • Cleaner Emissions: Gaseous generators, such as natural gas generators, produce cleaner emissions compared to diesel generators. They have a lower impact on the environment and contribute to a cleaner and greener energy solution.
  • Lower Fuel Costs: Natural gas, a commonly used fuel for gaseous generators, is often cheaper than diesel fuel. This can result in significant cost savings, especially for long-term projects or continuous power supply needs.
  • Quieter Operation: Gaseous generators are generally quieter than diesel generators. This makes them suitable for residential areas or locations where noise restrictions are in place.


  • Limited Availability: Gaseous fuel sources, such as natural gas or propane, may not be as readily available in all areas. This can pose a challenge if your project is located in a remote or rural location without access to a natural gas pipeline.
  • Higher Maintenance Requirements: Gaseous generators, particularly those using natural gas, may require more frequent maintenance compared to diesel generators. This is due to the complexity of the fuel delivery system and the need to ensure proper gas pressure and connections.
  • Lower Fuel Efficiency: Gaseous generators are generally less fuel-efficient compared to diesel generators. They may consume more fuel to generate the same amount of power, resulting in higher fuel costs over time.


When it comes to generator hire, both diesel generators and gaseous generators have their own set of advantages and disadvantages. Diesel generators offer fuel efficiency, durability, and low maintenance requirements, but they can be noisier and emit more emissions. On the other hand, gaseous generators, such as natural gas generators, provide cleaner emissions, lower fuel costs, and quieter operation, but they may have limited availability and require more maintenance.Ultimately, the choice between diesel generator hire and gaseous generator hire depends on your specific power needs, location, and budget.
