Operation and maintenance
Keeping your charging network live depends on fast response and reliable service. Our operations and maintenance team provides complete support for electric vehicle infrastructure, substations, and electrical connections.
We manage every stage of the process, from logging requests to repairs and reporting, so downtime is kept to a minimum and your customers stay moving.
When an issue is raised, it’s logged instantly and tracked in real time. We'll assign the nearest qualified engineer within minutes, based on skillset and availability. On site, the engineer runs safety checks, diagnoses issues, and carries out repairs, uploading every test and photo as they go. You get visibility at each step, plus a clear summary and quote for any follow‑up actions.
Every ticket is reviewed, feeding insights back into continuous improvement. This cycle of react, report, respond, and repair keeps your infrastructure performing and builds long‑term reliability. With us, you have one expert team focused on keeping your network responsive, safe, and ready whenever it’s needed.

Emergency call-outs
We provide rapid response emergency call-outs for high-voltage and low-voltage systems, electric vehicle charging infrastructure, solar photovoltaic arrays, and battery energy storage systems.
Common issues we respond to include power outages, equipment trips, communication failures, faulty connectors, inverter faults, cable or switchgear damage, battery management systems alarms, and vandalism.
Every intervention is followed by thorough functional testing to confirm safe and reliable operations.
Corrective maintenance
Providing a fast, effective response to restore equipment functionality after a fault or failure is imperative to reduce downtime. We identify issues through customer reports, automated monitoring, or routine inspections.
If on-site intervention is required, our qualified technicians carry out repairs in line with strict safety protocols, isolation procedures, and manufacturer specifications. The can include high-voltage switchgear or transformer component replacement, low-voltage distribution board or cabling repairs, electric vehicle charger component swaps, photovoltaic inverter repairs, or battery energy storage system maintenance.
Preventive maintenance
We carry out preventive maintenance to ensure ongoing reliability, operational efficiency and asset longevity. Our regular planned inspections cover the full range of electrical, renewable and charging assets including:
- High-voltage equipment
- Low-voltage systems
- Electric vehicle chargers
- Solar photovoltaic systems
- Battery energy storage systems
All preventive maintenance activity is fully recorded for compliance, trend analysis and continuous improvement. This ensures systems operate safely and efficiently, with maximum uptime for users.
Predictive maintenance
By combining data analytics, IoT sensors, and AI-driven models, we continuously monitor the condition of critical assets such as high-voltage transformers and switchgear, low-voltage distribution panels and cabling, electric vehicle charger power modules and connectors, photovoltaic inverters and panels, and battery energy storage system modules, control systems and cooling units.
This data-driven approach support regulatory compliance, enhances user experience, and ensures safe, efficient and cost-effective operation of networks.
Additional site services
We provide comprehensive site services that complement our core maintenance, ensuring all aspects of site management are professionally handled to maintain safety and accessibility.
- Housekeeping
- Landscaping
- Fencing
- Locksmith Services
