We supply diesel generators for both small- and large-scale applications. The right generator for you depends on numerous factors, including the size of your business or home, the type of equipment you power, and compliance regulations.
While all modern generators have noise-reduction features, silent generators leverage advanced acoustic enclosures to significantly reduce noise levels.
If you’re looking for a reliable backup power supply for a residential home, office, healthcare setting or other noise-sensitive environments, opting for a silent generator is a wise investment.
You can still keep essential appliances and equipment running without causing extensive disruptions.
Our most popular gensets are standby generators. Modern models usually include an automatic transfer switch (ATS) that activates the generator when you lose access to your main power supply.
Standby generators kick in immediately, powering security systems, safety equipment, appliances, and life-saving devices. Once your electricity source becomes available, the ATS will safely shut down the generator.
Large manufacturing environments that power heavy-duty equipment need a capable generator. Industrial diesel generators are built for demanding environments. Each high-capacity unit delivers a consistent power supply when you need it most.
These models are designed for longevity and will withstand heavy loads for longer periods. They’re also highly durable, but cost more than lower-capacity models.
Selecting a diesel generator isn’t just about choosing the right size for your needs. You’ll also need to factor in the environment it will run in, whether you need a single- or three-phase generator, noise levels, and other factors.
The first step is to decide how much power you need. Most generator capacities are measured in kilowatts (kW) and kilovolt-amperes (kVA). Choosing a lower capacity generator can cause system failures and overloads, while larger models cost more to run and increase fuel consumption.
Single-phase generators are best for small commercial applications and residential properties. A single-phase model will provide enough power for small-scale environments. If you’re powering a large building, heavy-duty equipment or a facility with high power demands, three-phase models are best.
Runtimes determine how long the generator can operate continuously or during an outage. Diesel is one of the most efficient fuels, making it more popular than petrol for standby power. Consumption rate, fuel tank size, and logistics should all factor into your decision.
Residential and urban environments often require silent diesel generators to prevent disruptions to neighbouring properties. If you have a remote agricultural operation or industrial site, you may be fine with a louder generator, but it depends on planning and environmental requirements.
Environmental conditions should play a key role in your decision. For example, if your generator will be outdoors, you should consider weather exposure, temperature fluctuations, and dust. Outdoor systems need weatherproof canopies, while indoor models could require ventilation.
Monitoring systems and control panels often come with modern generators. They’re ideal for diagnosing faults, remotely monitoring your generator, and running automated tests. Smart controls give you peace of mind and streamline generator maintenance.
We supply generators for a variety of industries across the UK. Whether you need prime power or reliable standby power, we can help you. Our generators are suitable for:
If your industry also has specific compliance requirements, we’ll help you choose the right generator.

Yes. Diesel generators are extremely reliable when serviced correctly and when fuel quality is properly maintained. With routine servicing and fuel management, diesel generators offer dependable performance for both standby and continuous power applications. Solent Power can provide servicing and maintenance tailored to your generator and usage requirements.
When serviced at the correct intervals, a high-quality diesel generator can operate reliably for 20–30 years or more. In many cases, generator life can be extended through major engine overhauls, control system upgrades, and proper fuel management over its lifetime.
There are many types of diesel generators available from different manufacturers, ranging from standard off-the-shelf units to fully bespoke systems. With so many options, it is important to clearly understand your power requirements, runtime needs, and installation environment. Solent Power provides expert guidance throughout the selection process.
Diesel generators typically start from around £950 for smaller units and can exceed £100,000 for large, bespoke installations. The final cost depends on generator size, specification, installation complexity, and additional equipment. Solent Power aims to recommend the smallest suitable generator to minimise fuel consumption, maintenance costs, and initial investment.
Diesel generators are used by homeowners, businesses, and industrial operators who require reliable backup or primary power. They are also widely used as portable power sources for equipment that petrol generators cannot support.
Diesel generators are usually the go-to choice because they’re long-lasting, fuel-efficient, and can power higher loads than petrol generators. Most standby generators use diesel, but you might find smaller portable generators use petrol.
It depends on your total electrical load. You’ll need to calculate the wattage of everything your generator will power, while also factoring in startup currents. If you’re not sure, please take a look at our comprehensive generator size guide or contact us for support.
Yes, some people choose to rent a generator rather than buy one outright. If you’re planning an event or need a temporary solution for off-site operations, hiring a generator can be more affordable.
We have a range of diesel generators for hire, and can advise on the best route for your immediate and long-term power needs.
Yes. We have a comprehensive selection of silent and super-silent diesel generators suitable for residential, commercial, and noise-sensitive environments.
We do offer used generators, subject to availability. Every single used generator on our website has undergone extensive safety checks.
