As an authorised Cummins CPG reseller and an authorised Grupel and Pramac dealer, we offer highly competitive pricing across all three ranges, supported by a large physical stock ready for fast dispatch.

Diesel Power for a Wide Range of Applications

Diesel power is used wherever a reliable power supply is essential. That might be a standby diesel generator for a business premises, a diesel generator off grid for a remote site, or a larger industrial package for continuous power in a demanding environment.

Our customers use diesel gen sets for factories, farms, construction sites, data centres, telecoms, healthcare, retail, hospitality, residential backup and export projects. A well-specified generator/diesel generator set can support anything from lighting and security systems to heavy machinery, cooling equipment, pumps, compressors and full-site electrical loads.

Compared with a petrol generator, a diesel fuel generator is usually better suited to larger loads, longer run times and commercial use. Diesel engines are designed for strength and efficiency, which makes them ideal for standby power, emergency backup and prime power applications. Thanks to the efficiency of diesel, diesel generator sets offer a more economical and reliable solution.

Silent, Open, Canopied and Containerised Options

Choosing the right configuration is just as important as choosing the right size. Silent diesel generators are fitted inside acoustic canopies to reduce noise, protect the equipment and make outdoor installation easier. These are often the best choice for commercial premises, residential backup, farms, workshops and sites where noise levels matter.

Open diesel electric generators are typically used indoors, inside plant rooms or within purpose-built enclosures. They are a good option where the generator already has protection from weather and where access for installation, servicing and airflow can be planned around the site layout.

For larger power requirements, containerised diesel gensets provide a robust, secure and practical power solution. They are commonly used for industrial sites, utilities, export projects and high-power standby generators where durability and ease of transport are important.

Single Phase and 3 Phase Power

We supply both single phase and 3 phase diesel generators from the UK. Single phase models are often suitable for homes, small workshops, offices, farms and smaller commercial buildings. They can support lighting, sockets, heating controls, security systems and other everyday electrical loads.

3 phase diesel generators are designed for larger commercial and industrial environments. They are commonly used for machinery, production equipment, motors, pumps, HVAC systems and full-site backup. If your site has a 3 phase supply, you will usually need a 3 phase generator diesel system to match the existing electrical infrastructure.

Our team can help you compare kVA, kW, voltage, phase type and starting loads so the generator set is properly matched to your application. This is especially important where motors, compressors or other high-starting-current equipment are involved.

Standby, Prime and Continuous Power

Different sites need different operating modes. A standby diesel generator is designed to provide emergency power when grid power fails. It normally remains idle until there is an outage, then starts automatically or manually to restore supply.

Prime power models are used where the generator is the main source of electricity for extended periods. This is common for off-grid locations, remote industrial sites, temporary facilities and export projects where mains electricity is unavailable or unreliable.

Some applications also require continuous power, where the generator runs for long operating periods under a steady load. In these situations, correct sizing, ventilation, fuel planning, control systems and maintenance access all become especially important.

Automatic Backup with ATS Panels

For many backup applications, an automatic transfer switch is a key part of the system. When grid power fails, the ATS detects the outage, starts the generator and transfers the electrical load. When mains power returns, it transfers the load back and shuts the generator down safely.

This creates a smooth emergency backup system for businesses that cannot afford long interruptions. It is particularly useful for sites with refrigeration, IT equipment, telecoms, security systems, production lines, healthcare facilities or essential building services.

We can supply control panels and transfer equipment to help create a complete diesel power generator package. The right control setup makes operation simpler, safer and more reliable.

New Diesel Generators from Trusted Brands

Global Generators supply all brand new equipment, nothing used/2^nd hand or for hire. This gives customers the benefit of unused machinery, clear specifications and long-term value.

Our Cummins range is especially strong. As an authorised Cummins CPG reseller, we offer the UK’s best pricing on Cummins diesel generators, backed by expert product knowledge and physical stock. We also supply Grupel and Pramac generator sets powered by Perkins and Yanmar diesel engines, giving customers additional choice across a wide range of power ratings.

Some buyers also compare our range with other well-known names such as CAT, FG Wilson and MTU. Our team can help you compare output, engine manufacturer, canopy design, alternator specification, controller type, price and availability so you can choose the most suitable diesel genset for your site.

Understanding Diesel Generator Prices

Diesel generator price depends on several factors, including power rating, brand, engine type, alternator, canopy design, control system, fuel tank, phase type and optional extras. A compact single phase model for home backup will usually cost far less than a containerised industrial generator built for high-power standby or prime use.

The cheapest option is not always the best long-term value. A properly specified diesel generator for sale should be matched to your load, site conditions, installation plan and future requirements. Undersizing can cause performance issues, while oversizing can reduce efficiency and increase unnecessary cost.

If you are comparing a diesel genset price, check what is included. Important details include whether the unit is silent or open, whether delivery is included, what control panel is fitted, whether an automatic transfer switch is required, and whether the generator is available from stock.

Fast UK Delivery and Global Export

We are a leading stockist of generators and diesel equipment, holding a wide range of models in our physical inventory. This helps us offer fast delivery across the UK and efficient export worldwide.

Customers searching for diesel generator UK suppliers often need more than a brochure and a long factory lead time. They need real availability, clear pricing and practical advice from people who understand generator supply.

We regularly support customers looking for generators/diesel generators Europe-wide, as well as buyers in the Middle East, Africa and other international markets. Supplying from the UK gives customers access to high-quality industrial equipment, export support and responsive communication throughout the buying process.

Choosing the Right Diesel Motor Generator

The right DG (diesel generator) depends on how it will be used. Start by listing the equipment you need to power, then consider whether the generator will be used for standby, prime or off-grid operation. You should also check whether your site needs single phase or 3 phase output.

Fuel capacity, noise levels, space, ventilation, access, delivery route and installation location all matter. Diesel fuelled generator packages for remote sites may need a larger fuel tank and strong weather protection, while a commercial standby set may need an ATS panel and acoustic canopy.

While there are many different names people use to describe a generator/diesel motor generator, they all boil down to the same basic requirement: a diesel engine driving an alternator to produce electricity. The most important thing is choosing equipment that suits the load, environment and duty cycle.
