Generator service and maintenance
Scheduled maintenance programs ensure your generators stay in peak condition year-round
Regular servicing reduces downtime, extends equipment life and prevents costly breakdowns. Planned preventative maintenance is essential for keeping your standby generator in normal working order all year. Maintenance is typically biannual, but our other options are weekly, monthly or quarterly, depending on generator usage, conditions and environment. We understand the need for continuous, on-demand power, which is why we ensure that your backup power is readily available, reliable and robust. We work with clients to ensure that they have the correct service plan.
While prime generator maintenance demands that all fluids and filters are replaced every 500 hours or 3 years, most standby applications will struggle to complete that workload. We offer a tailored plan, including condition-based servicing that includes oil analysis and reporting, which is more cost-effective and environmentally friendly than replacing all filters annually.

Pharos Generator Services (PGS) offers professional load bank testing, fuel polishing and tank cleaning services to ensure your power system is always performing at maximum efficiency.
When power failure occurs, your generator is a critical piece of equipment and is relied upon heavily. The process is essential for preventing issues that may lead to slowness or reduced generator functionality.
What is load bank testing?
A load bank test is vital to maintain equipment and ensure that when generation is needed, the generator will respond accordingly by being dependable, operational and capable of taking the maximum design weight. A generator must start and take loads immediately when the main power supply fails. This will ensure you minimise business activity downtime. And because your diesel-powered machine will be used infrequently, you need complete confidence that it will be fully operational without fail, despite being inactive.
The most common issue is wet stacking
The most common issue is wet stacking
Wet stacking is the build-up of soot and unburned fuel deposits over time in the exhaust system. This occurs when diesel dynamos are operated infrequently and/or are only subjected to light weights. It can damage the dynamo’s internal workings and cause it to perform erratically. Analysis is useful to ensure that these fuel and soot deposits are burnt off to reduce the risk of wet stacking.

It also ensures capability and battery autonomy, in addition to making sure that the generator’s primary components are working correctly under loaded conditions.
Test components involve analysing oil pressure stability and investigating if the cooling system performs to the required standard. Results will determine if the machine overheats.
Each load test is designed for each specific machine

We test the generator over a range of loads, monitoring and data gathering constantly for 2–4 hours. We have multiple sized load banks nationwide, from 2 kW–2 MW, to suit all applications.
Maintenance and 24/7 emergency support
When power fails, our dedicated emergency response team is available 24 hours a day, 7 days a week, providing rapid on-site assistance across the UK. We offer tailored service plans (weekly, monthly or quarterly) based on usage and environment.
Our condition-based servicing includes oil analysis and reporting, which is often more cost-effective and environmentally friendly than blanket filter replacements. All maintenance is delivered by experienced engineers.
