Our Process
Site Assessment & Audit
We begin with a detailed assessment of your existing electrical infrastructure to understand your current system capabilities, load requirements, risk factors, and operational goals.
Design & Specification
Following the assessment, our team creates custom electrical system plans, selects appropriate components, and ensures that all specifications meet regulatory and compliance standards.
Installation & Commissioning
Once approved, we move into installation. Our experienced electricians ensure the safe and efficient delivery of your system. We complete full commissioning and testing prior to handover.
Ongoing Maintenance & Support
After installation, we offer scheduled maintenance services to ensure long-term performance and reliability. Our support includes emergency callouts, inspections, testing, and upgrades as needed.
Supporting Your Site Operations
Flexible Servicing Wherever You Need It
Servicing is carried out on-site wherever possible to minimise disruption to your operations. Our mobile technicians arrive with all required tools and parts to perform generator servicing efficiently, whether you’re running a commercial site, industrial facility or remote mining operation. If in-depth diagnostics or component replacement is required, we can transfer your generator to our fully equipped service centre for off-site repair.
As your servicing partner, we help schedule future services based on operational hours, environment and manufacturer timelines to ensure your system remains compliant and ready.
