For those in remote locations or agricultural sectors, we provide robust backup generator systems that guarantee seamless power during grid failures.
Every unit we supply is backed by our technical team, who specialise in professional generator installation. We don’t just deliver a box; we provide a turnkey solution including site surveys, ATS panels integration, and final commissioning. Beyond the initial setup, we are your long-term power partner, offering comprehensive generator servicing and maintenance to keep your equipment in peak condition. And, should the unexpected happen, our rapid-response engineers are always on standby for emergency generator repair, covering the entire UK 24/7.
FREQUENTLY ASKED QUESTIONS
Understanding the duty cycle of your equipment is vital. A backup generator (Standby) is specifically rated for emergency use during temporary mains failure. These units are optimised to sit idle for long periods and start instantly when needed. In contrast, a Prime Power diesel generator is engineered to act as the primary source of electricity, built for continuous operation in locations where a grid connection is either unreliable or completely non-existent.
We recommend a technical consultation to calculate your peak load and "starting currents" to ensure your generator operates at the correct efficiency and avoids issues like "wet stacking" caused by under-loading.
Our silent generator UK range is designed to solve the challenge of noise pollution in sensitive environments. These units are housed in zinc-treated, anti-corrosive steel enclosures lined with high-density, fire-retardant acoustic foam. By utilizing advanced air-flow baffles and specialized exhaust silencers, we can reduce noise levels to as low as 65-70dB at 7 metres. This makes them the ideal choice for residential backup, outdoor events, or office complexes where maintaining a quiet environment is a legal or operational necessity.
Absolutely. If a permanent capital purchase isn't the right fit for your current project, we offer a comprehensive generator for hire service. Our hire fleet consists of modern, sound-attenuated units that are maintained to the same rigorous engineering standards as our sales stock. This provides a reliable, cost-effective solution for short-term construction sites, seasonal event power, or as a temporary bridge during facility upgrades.
A professional generator installation involves high-level electrical and mechanical engineering. It isn't just about positioning the unit; it requires the safe integration of an Automatic Transfer Switch (ATS) into your building's main distribution board, the installation of compliant fuel storage systems, and the management of exhaust gasses. Our certified engineers ensure that the entire installation meets current UK electrical regulations and manufacturer warranties, protecting your investment and your safety.
Our generator servicing and maintenance is a multi-point preventative program. We perform comprehensive oil and filter changes, cooling system pressure tests, battery health diagnostics, and control panel firmware updates. Critically, we also offer Load Bank Testing, which stress-tests the generator at its full rated capacity to ensure it can handle your building's actual load during a real-world power cut. Regular maintenance is the only way to guarantee 100% "start-on-demand" reliability.
Power failure doesn't stick to office hours. If your system fails to start or shows a critical alarm, our 24/7 emergency line connects you directly to technical support. We provide nationwide generator repair services, with engineers dispatched from our UK headquarters carrying a wide range of common spares for brands like Cummins, Perkins, and Kohler. Our goal is always to diagnose and repair the fault on the first visit to keep your critical systems online.
