Maintenance & Health Checks

Keep UPS systems reliable before wear becomes downtime.

A UPS is only as reliable as the condition it is kept in. Regular maintenance and health checks identify weakening batteries, heat-related issues, worn components and configuration risks before they interrupt your site.

Our engineers inspect the complete UPS installation, review operating conditions and provide clear reporting with practical next steps.

Health checks can include

Visual inspection of UPS and battery sets
Electrical connection and thermal checks
Battery condition and runtime review
Environmental checks for dust, heat and humidity
UPS history log review and firmware advice
Fault report with prioritised recommendations

Preventative Care

Maintenance built around uptime

The aim is to find deterioration early and keep your UPS ready for the power event you cannot schedule.

Health check process

Step 1
Book Visit

Confirm UPS type, site access, load sensitivity and maintenance history.
Step 2
Inspect

Check batteries, electrical connections, logs, environment and operating state.
Step 3
Report

Document findings, risks and recommended remedial work in plain language.
Step 4
Plan

Agree maintenance, replacement or follow-up actions around your operations.

Flexible Support

Available as planned maintenance or an ad-hoc health check

Some sites need ongoing maintenance cover. Others need a focused inspection before a battery replacement, office move or infrastructure upgrade.

We shape the visit around the risk, age and role of your UPS rather than forcing every site into the same contract model.

Long-Term Partnership

Maintenance, battery replacement and monitoring support are available long after the first project.

“OnLiTECH gave us independent options, not a one-brand sales pitch. They modelled multiple UPS and battery combinations against our actual load profile, explained the trade-offs clearly, and delivered an installation that was completed on programme with minimal disruption to teaching facilities.”

Head of IT Infrastructure University Sector • Education Client

“From initial survey to commissioning, everything was handled by one accountable team. The project plan, RAMS documentation and handover pack were all well structured, and their response times during and after installation have been consistently fast and reliable.”

Facilities Manager Healthcare • NHS Partner Site

“Their maintenance support has materially reduced risk across our estate. Preventive visits are proactive, reporting is clear, and any faults are prioritised quickly, which has given us far greater confidence in our backup power resilience during critical service windows.”

Operations Director Government and Local Council • Council Services

“The project team planned around a live environment with strict uptime requirements and delivered without service interruption. They coordinated access carefully with our operations team, phased the works sensibly, and kept stakeholders updated at every stage of the project.”

Data Centre Manager Corporate Organisation • Enterprise Client

“They helped us select the right UPS and battery package for our customers’ load profiles rather than pushing the highest-cost option. That technical clarity has improved our own proposals, reduced lifecycle cost surprises, and strengthened client trust in our recommendations.”

Procurement Lead IT Reseller • Channel Partner

“Survey quality was excellent and the commissioning paperwork was complete and easy to audit. Their engineers documented test results and certification details to a high standard, which made compliance sign-off straightforward for our internal governance and external reviewers.”
