Our Services
Complete Electrical Solutions
TES provides a broad commercial and industrial service, allowing clients to use one experienced contractor for electrical installation, air-conditioning installation and electrical supplies, testing, lighting, renewable energy, security infrastructure, data infrastructure and ongoing maintenance.
Electrical work designed around your building
Whether you are refurbishing an office, upgrading a warehouse, improving energy efficiency, adding security infrastructure or maintaining a larger property portfolio, our approach is built around safe installation, sensible coordination, proper testing and clear communication.
We can work as the electrical contractor within a larger construction project, support a facilities-management partner, deliver planned maintenance or deal directly with the building owner or occupier.
Our commercial experience means we understand occupied buildings, restricted access, shutdown planning, working alongside other trades and the need to leave clients with a safe, documented installation.
Testing & Compliance
EICR inspection and testing, electrical certification, fault investigation, remedial works and planned testing programmes. We can help identify defects and prioritise practical remedial action.
Solar PV & Battery Storage
Commercial solar PV, battery storage and electrical integration designed around roof space, electricity demand and the existing electrical installation. Use our Solar page for an indicative planning calculator.
