Standby generator servicing and testing
Generator servicing and maintenance, automatic transfer switch (ATS) testing and load bank testing, so standby power is ready when the mains supply fails.
The challenge
Standby power has to work first time
A standby generator only protects a building if it starts, takes the load and hands back to the mains cleanly. Without regular servicing and testing, faults stay hidden until there is a power cut.
Standby generator servicing sits alongside our gas, heating, mechanical, electrical and water hygiene support, so property managers have one clear point of responsibility across the whole building.
What's included
Servicing and testing that proves your standby power works
Generator servicing and maintenance, ATS testing and load bank testing.
Generator servicing & maintenance
Planned servicing keeps the generator ready to start and run whenever the mains supply fails.
Automatic transfer switch (ATS) testing
We test that the ATS moves the building’s load onto the generator when the mains fails, and hands it back cleanly when the supply returns.
Load bank testing
The generator is run against a controlled load, to prove it can carry the building’s demand and not just start up.
