At Generators For Export, we’ve spent years helping customers across the UK and overseas get the reliable power solutions they need. But even with all the knowledge available today, we still hear the same misconceptions about generators time and time again.
Whether you’re looking for a used diesel generator for your business or just trying to understand your options, don’t let misinformation cost you time or money. In this article, we’re setting the record straight on the most common generator myths.
Myth 1: Used Generators Are Unreliable
This is probably the biggest misconception we come across, and it's simply not true.
The reality is, a well-maintained used generator can offer the same performance and longevity as a new one, often at a significantly lower cost. At Generators For Export, every used generator we sell is fully tested, inspected, and serviced to meet high-quality standards. We often source from low-hour standby units, meaning they’ve seen minimal use and are in excellent condition.

Myth 2: Diesel Generators Are Always Noisy
While older models may have given diesel generators a bad reputation for noise, modern technology has come a long way. Many generators, especially those designed for standby use, come equipped with acoustic canopies and advanced mufflers to reduce noise levels significantly.
Even our used generator range often includes low-noise models perfect for residential, commercial, and event use. If sound levels are a concern, ask us about generators with noise ratings below 70 dB(A) at 7 metres.

Myth 3: You Only Need a Generator in Remote Locations
Many people assume generators are just for remote sites or construction zones, but power outages can hit anywhere, anytime. Whether it’s a storm, grid failure, or infrastructure work, businesses in urban areas are often caught out without a backup plan.
A generator is your first line of defence against power loss, protecting your operations, equipment, and revenue. We work with schools, care homes, data centres, and offices that can’t afford downtime, no matter their location.
Check out our guide on how to choose the right generator for your business.
Myth 4: Bigger Is Always Better
Buying an oversized generator might seem like a safe bet, but it can actually cause problems.
Running a generator well below its capacity can lead to "wet stacking," where unburned fuel builds up in the exhaust system. This not only reduces efficiency but can also lead to costly damage over time. The key is proper generator sizing, based on your actual load requirements.
At GFE, we’ll help you calculate your power needs and recommend the right kVA output for your application, no guesswork involved.

Myth 5: Generators Are High Maintenance
While all engines need maintenance, modern diesel generators, especially from trusted brands like Cummins, Perkins, Baudouin and Volvo, are built for reliability and ease of service. In fact, diesel generators generally require less frequent servicing than petrol counterparts.
When you buy from us, we’ll walk you through basic upkeep and can connect you with trusted engineers for long-term support. If you’re buying for export, we can even help you understand local maintenance needs and parts availability.
Myth 6: Generators Are Bad for the Environment
Diesel engines are often targeted as major polluters, but it’s important to look at the bigger picture. Used generators can actually be the more sustainable option. Reusing quality machinery keeps it out of landfills and reduces the demand for raw materials and manufacturing energy.
In addition, many of our units comply with modern emission standards, and fuel-efficient engines reduce overall consumption. For those who need cleaner alternatives, our sister company GFE Power Products offers Stage V-compliant and hybrid solutions by request.
