Factory Acceptance Testing (FAT)

At Shenton Group, Factory Acceptance Testing isn’t a box-ticking exercise; it’s a commitment. We rigorously test every generator system before it leaves our facility, ensuring it performs exactly as specified and delivers total peace of mind when it matters most.

FATs can be attended in person at our Andover facility, where clients are welcome to witness the test first-hand. Where this isn’t possible, we also offer live remote video feeds, allowing you to observe the process in real time from anywhere.

What is FAT?

The Factory Acceptance Test is a critical stage in our quality assurance process. It verifies that your equipment:

  • Is correctly assembled and manufactured
  • Operates to specification under simulated real-world conditions
  • Meets all advertised ratings and performance criteria
  • Is ready for seamless integration on-site

Our Testing Philosophy

We don’t settle for “good enough.”

  • Every system is run and rerun until we’re completely satisfied
  • Pre-FAT tests are conducted to eliminate surprises and ensure smooth final testing
  • Only trained engineers work on live generator sets, with full safety protocols in place
