We Buy Your Generator
- Finance Available, on all new generators.
We supply generators up to 20kVA across the UK, with stock available for immediate delivery. Our range includes high-performance diesel generators engineered to deliver reliable performance across construction, commercial and residential environments.
When power fails, the impact is immediate. Downtime, lost productivity, and damage to power-sensitive electrical equipment can all follow. Generators in the 11–20kVA range provide the capacity needed to maintain operations, protect equipment and ensure providing electricity when it is needed most.
Whether you need residential backup use, temporary power or a solution for ongoing operations, we can supply a generator that meets your exact requirements and performs reliably under load.

A generator up to 20kVA is suitable for powering a wide range of equipment, making it ideal for construction sites, small industrial applications and residential backup use. It can support tools, lighting, heating systems and essential appliances depending on the overall load.
These generators are also commonly used to provide electricity for site offices, outdoor setups, and temporary installations. When correctly matched to your power requirements, they deliver reliable performance across a range of environments.
Yes, generators in this range are widely used for backup power, particularly in businesses, commercial buildings and residential properties. In the event of power outages, a standby diesel generator can quickly restore power and help prevent disruption.
This is especially important when operations must be maintained or equipment must remain powered. Having a backup generator in place provides peace of mind, ensuring you have a reliable solution when mains power fails.
The choice between a single-phase and a three-phase diesel generator depends on the equipment you are running. Single-phase generators are typically used for residential and smaller commercial applications, while three-phase generators are required for larger or more complex systems.
If you are powering industrial equipment or multiple systems at once, a three-phase generator is usually the better option. If you are unsure, it is important to review your requirements before investing, as selecting the correct setup ensures safe and efficient operation.
Fuel efficiency depends on how the generator is used and whether it is correctly matched to your load. A generator operating at the right capacity will use fuel more efficiently and provide consistent output without unnecessary waste.
Modern diesel generators are designed to optimise fuel consumption, particularly when running under steady load. Regular maintenance and proper use will also help maintain efficiency and extend the unit’s lifespan.
Certainly! A 20kVA generator can be equipped with an automatic start feature, enabling it to start and operate automatically in response to power outages or predetermined triggers. This feature ensures uninterrupted power supply without the need for manual intervention, enhancing convenience and reliability.
Yes, generators up to 20kVA are commonly used for temporary power and equipment hire, particularly across construction, events and outdoor environments. Their capacity makes them suitable for powering tools, lighting and site equipment over short or extended periods.
They are often used during a hire period where flexible power is required, and their portability allows them to be deployed across multiple locations. This makes them a practical solution for contractors, businesses and professionals working across different sites.
Yes absolutely. Here at Bellwood Rewinds, we are experts in determining what generator will suit your needs. If you think you may need a 20 kVA generator but you are not sure, it is best to speak with us before ordering as you may needs a generator with much more power or potentially much less power. Feel free to give us a call to discuss your generator requirements.
A 20 kVA generator refers to a generator with a power output of 20 kilovolt-amperes (kVA), suitable for various applications such as small businesses, offices, construction sites, mobile catering operations, events and festivals, backup power for homes, small industrial equipment, telecom towers, healthcare facilities (for critical equipment), outdoor lighting setups, emergency response operations, remote job sites, small data centres, recreational vehicles (RVs), boats and marine applications, mobile clinics, agricultural operations (e.g., powering pumps), temporary power needs, remote monitoring stations, and mobile workshops. Assessing specific power requirements, environmental conditions, fuel type, portability, noise levels, and maintenance requirements is essential when selecting a generator to ensure it meets the needs of the intended application adequately.
