Diesel Generators For Sale

The cost of a diesel generator can vary significantly depending on several factors including power output (kVA), whether the unit is new or used, the level of sound attenuation (open frame vs silenced), and whether it’s designed for standby or continuous use. At Bellwood Rewinds, our diesel generators typically start from around £2,000 for compact, lower-capacity models and can exceed £20,000 for high-specification, high-output generators suited to industrial applications.

Reconditioned or used diesel generators can offer considerable savings while still delivering reliable, long-lasting performance. Many of our refurbished units come fully load tested, serviced, and inspected to ensure they’re ready for immediate deployment. For customers with more specific requirements—such as three-phase output, ATS compatibility, or extended run tanks—prices can be tailored based on the customisation involved.

We always recommend speaking with our team to get an accurate quote based on your exact power needs, installation conditions, and runtime expectations. Whether you’re powering a small business, a rural property, or large equipment, we’ll help you find a cost-effective solution that suits your budget without compromising on reliability.

The smallest diesel generator we currently stock is the Teksan 16kVA Single Phase Silenced Diesel Generator, offering a prime power output of 15kVA and a standby power of 16kVA at 230V single phase. Powered by a reliable Baudouin engine paired with a Leroy Somer alternator, this compact unit is ideal for small-scale applications. It features a Deep Sea manual/auto start panel for flexible operation, a 90-litre bunded fuel tank for extended run times, and operates at a low noise level of 68dBa at 7 meters—perfect for noise-sensitive environments.

Our inventory of diesel generators is constantly being updated, so if you’re looking for a different size, whether smaller or larger, we can help source the perfect generator to meet your needs. Contact our team to discuss your requirements or to explore the full range of options available.

The decision to buy a used or new diesel generator depends largely on your budget, expected usage, and how soon you need the equipment. New diesel generators offer the advantage of the latest technology, longer warranties, and full manufacturer support. They’re ideal for customers who need long-term power solutions or want the peace of mind of owning a unit with zero operational hours.

However, used or reconditioned diesel generators are a fantastic option for many buyers—especially when purchased from a reputable dealer like Bellwood Rewinds. Our used generators are fully inspected, load tested, and serviced before being offered for sale. They often provide excellent value for money, delivering robust performance at a significantly reduced price point.

If you’re looking for short-to-medium-term use, have budget constraints, or need a generator quickly, a quality used diesel generator can be the ideal solution. On the other hand, if your generator will be operating continuously in a critical setting, a new model may offer longer service life and greater ROI.

We’re happy to talk through your specific needs and help you compare the options, ensuring you choose the most suitable and reliable unit for your intended application.

Yes, Bellwood Rewinds stocks a wide range of silenced diesel generators, also known as soundproof or acoustic generators. These are ideal for applications where noise reduction is a priority—such as residential areas, outdoor events, construction sites, mobile businesses, or agricultural settings where livestock are present.

Our silenced generators are enclosed in sound-attenuated canopies or containers, significantly reducing noise levels compared to open-frame models. Depending on the specification, many operate between 60–75 dB at 7 metres, making them suitable for environments where low-noise operation is critical.

We supply silenced diesel generators throughout the UK in various power ratings, from small portable units to large industrial models. Whether you need backup power for a rural property, continuous power for an event, or a quiet standby generator for a commercial site, we can help you find the perfect unit.

Most of our silenced generators are available with features such as AVR, electric start, and compatibility with automatic transfer switches (ATS). We also offer reconditioned silenced models, which are thoroughly serviced and tested before resale. Get in touch to discuss your specific requirements—we’ll help you choose a quiet, efficient generator that performs exactly how and where you need it to.

Yes, all of our diesel generators come with a warranty—whether you’re purchasing a new or reconditioned model. For new diesel generators, the warranty is typically provided by the manufacturer and can range from 12 to 24 months depending on the brand and intended usage. Some commercial-grade units offer extended warranties when maintained as per the service schedule.

Our reconditioned and used diesel generators come with a standard 6-month warranty, providing peace of mind that your unit has been professionally inspected, serviced, and load tested prior to sale. This warranty covers key components such as the engine and alternator and is designed to ensure your investment performs as expected.

We understand that backup power is critical to many businesses and homeowners, which is why we stand behind the reliability of the products we sell. If any issues arise during the warranty period, our support team is on hand to resolve the problem quickly and professionally.

In addition to our standard warranties, we also offer ongoing maintenance packages, servicing options, and replacement parts to extend the life and efficiency of your generator long after the initial purchase.
