What Is Load Bank Testing?


Load bank testing simulates real-world electrical demand to assess your generator’s performance and reliability. By safely applying a controlled load, it helps identify hidden issues such as wet stacking (unburnt fuel build-up in the exhaust) or underperformance before they become critical.

Why Regular Load Bank Testing Matters in the UK


Regulatory Compliance & Contract Requirements:  Many sectors, including NHS trusts, water utilities and Ofgem-regulated energy providers, require formal load bank testing to meet compliance, framework and insurance policies.

Seasonal & Emergency Preparedness: Storms, grid instability, and critical operations demand guaranteed power fallback.

Optimised Maintenance Scheduling: Scheduled testing reduces unplanned downtime and enhances service efficiency, and supports long-term maintenance planning in line with SFG20 guidance.

Very pro-active, when dates are moved, they seemed to do all they could to reposition to meet the streamlined targets, which were achieved. Seemed to conduct themselves in a very professional manner, which made our lives a lot easier, all the way from RAMS to O&M. All in all, very pleased with P & I and look forward to working together in the near future. I would recommend them to neighbouring companies.
