Professional load bank services, fault finding and performance verification. GCM offers fast, reliable generator diagnostics, load bank testing and troubleshooting to prevent failures and maintain continuous power.
At Generator Control & Maintenance, we provide load bank testing for generators to assess performance, confirm reliable operation, and identify potential issues before they develop into costly failures. During testing, we evaluate key factors including oil and fuel pressure, voltage stability, frequency control, and engine performance, allowing us to assess the overall condition of your generator and recommend corrective action where required.
We provide load bank testing across the UK for generators ranging from 20kW to 2500kW, helping businesses maintain reliable power and ensuring your generator is ready to perform when it is needed most.
Load bank testing uses a load bank to simulate an artificial electrical load in the power systems. During load bank testing for generators, the electrical load is gradually increased to assess overall generator performance and confirm that the system can handle operational demands when required.
Regular generator load bank testing is recommended annually, based on on the generator type, usage, and operational requirements. In critical environments such as hospitals and manufacturing facilities, more frequent load bank testing may be appropriate based on the specific application and manufacturer recommendations.
At Generator Control & Maintenance, our load bank testing procedures includes testing:
After completing our generator load bank testing, we assess the overall condition and performance of your generator and recommend the appropriate testing frequency based on its usage and operational requirements.
With our load banks for generator tests, we help businesses improve reliability, maintain system performance, and ensure their generators are ready to operate when needed most.
At GCM, we provide a range of load bank testing solutions to assess generator performance under different operating conditions. We select the most suitable testing method based on your generator system, power requirements, and operational environment.

Resistive load bank testing assesses whether your generator can deliver its rated power output safely and efficiently. Using this type of load bank testing we can evaluate engine performance, fuel systems, and overall generator operation under load.

Using reactive load bank testing we can evaluate generator performance under inductive and capacitive loads, such as those created by motors, transformers, and UPS systems.

Combined load bank testing assesses both resistive and reactive loads to provide a more complete evaluation of generator performance. We use this type of load bank particularly for complex commercial and industrial power systems.

Portable load bank testing allows us to test generators on-site using mobile load bank testing equipment. This type of load bank testing for generators is mostly used for rental generators, temporary power systems, and generators that require field testing.

Permanent load bank testing uses fixed load bank systems installed at the generator site for regular and scheduled testing. We commonly use it in facilities where reliable backup power is critical and frequent testing is required.
At GCM, we provide generator load bank testing and generator control solutions for a wide range of commercial and industrial sectors that rely on continuous and reliable power systems. Our engineers work with businesses across multiple industries to improve generator performance, reduce downtime, and maintain compliance with operational standards.
We support industries including:
Our generator load bank testing services are designed to help businesses maintain reliable standby power, improve operational efficiency, and identify potential generator issues before they lead to costly failures.
