Most UPS failures start with the batteries, and load-shedding wears them out faster than the datasheet says. A scheduled visit finds the problem before an outage does. Every plan states its response time and visit schedule up front.

Battery testing and replacement, done properly.
A VRLA bank is designed to last 3 to 5 years. With daily load-shedding it's often closer to 2 or 3, and it rarely warns you before it fails to hold the load.
- Free on-site battery auditString and block readings, terminals, temperature and ventilation, photographed as we go.
- Load test on your real loadA discharge test shows the runtime you actually have. If the bank still has life in it, we'll tell you.

One call when the power matters.
Most outages aren't caused by one faulty part. They happen where the battery, the UPS, the switchgear and the cabling meet, which is why we look after all four.
We answer at 3am
A 24/7 emergency line staffed by technicians who can talk you through a fault before they arrive.
Certified technicians
Qualified electricians and UPS specialists, with certificates of compliance issued on every installation.
The whole power chain
From battery to switchgear to cabling, one team is responsible, so nothing falls between contractors.
Honest, brand-neutral advice
We recommend what suits your load and budget, and we'll tell you when a repair makes more sense than a replacement.
Don't wait for the next outage.
We'll inspect your UPS, batteries and changeover setup, and tell you where your weak points are. No cost, no obligation.
