We Buy Your Generator
- Finance Available, on all new generators.
CAT generators are built for organisations that need dependable power across commercial, industrial and critical applications. Bellwood Rewinds supplies new and used Caterpillar diesel generators for construction, manufacturing, agriculture, healthcare, commercial premises and emergency backup throughout the UK.
Our stock includes silenced CAT generator sets across several power outputs, with models suitable for prime or standby duty. Availability changes regularly, so the right unit should be selected based on the connected load, phase, operating environment, required runtime, and future capacity, rather than the brand name or headline kVA alone.
Browse the CAT generators below, or contact our engineering team for tailored advice. We can help compare power ratings, condition, enclosure, controls, fuel arrangements and long-term support before recommending a suitable generator.

CAT generator sets are designed for commercial, industrial and critical-power applications across a wide range of industry sectors. Reliability still depends on correct sizing, installation, loading, fuel quality and preventative maintenance.
For buyers comparing long-term generator options, factors such as service history, operating conditions, maintenance records and parts availability all matter. Bellwood can help customers assess these points so they can choose a generator they can trust for the intended application.
The correct size depends on running and starting loads, phase, power factor, operating hours and future capacity. A generator should be selected based on the actual equipment it needs to support, rather than simply choosing the next available power rating.
Bellwood can review your equipment schedule and recommend an appropriate kW or kVA rating, helping ensure the generator remains suitable as site requirements change over the coming years.
Yes. Bellwood supplies used CAT generators alongside new equipment. Running hours, service history, engine condition, alternator performance and controller operation should all be assessed before purchase.
Choosing a suitable used generator can also be a more sustainable option when an existing machine still meets the specifications, condition, and support required for the intended application. The key is to ensure conditions and capabilities are properly assessed, rather than choosing based on price alone.
Price varies according to power output, condition, specification, enclosure, controls and emissions equipment. Current prices are shown where available, while other units may require a tailored quotation.
The lowest purchase price is not always the lowest long-term cost. Fuel use, maintenance requirements, expected operating hours, and the number of years the generator is expected to remain in service should all be considered when comparing options.
CAT generators are produced by Caterpillar Inc., a manufacturer with a long history of supplying engines, machinery and power equipment across the global industry.
Specifications and manufacturing arrangements vary across the generator range, so buyers should check the individual model information and nameplate before purchase. Bellwood can help interpret those details so customers can compare available CAT generators with greater confidence and trust in the specification.
Caterpillar designs generator sets as coordinated packages that combine the engine, alternator, controls, and supporting systems. The CAT diesel generator product range includes options for prime and standby duty, with individual sets assembled and tested before leaving the manufacturing facility. This integrated approach can simplify specification and provide stable performance when the generator is correctly sized, installed and maintained. In demanding environments, the right generator should be chosen based on the connected load, duty, site conditions, and long-term operating requirements rather than on headline output alone.
Depending on the model, CAT diesel generators may include sound-attenuated enclosures, EMCP control panels, automatic starting and options for different voltages and environmental conditions. The wider product range includes compact and larger stationary generator configurations for different commercial and industrial applications. These features vary, so the individual product specification should always be checked to ensure the generator type is suitable for the intended site and duty.
Standby generator sets remain ready to supply emergency backup when mains electricity fails. They may run infrequently, but still need healthy starter batteries, clean fuel and planned servicing.
Prime power generators are selected for regular operation where grid power is unavailable or unreliable. Their duty rating, cooling, fuel system and maintenance schedule must support longer running periods and changing loads. Some larger Caterpillar generator sets are also offered for continuous or mission-critical duty, but the rating must match the application.
