Initial Consultation & Site Visit
First, we meet with you to assess existing systems, understand usage needs, and identify goals or limitations. We then complete a site visit to gather layout, access, and distribution data.
Design & Specification
Based on your input, we develop a detailed specification and drawings, including load calculations, protection schemes, and distribution layouts.
Installation & Commissioning
Our engineers install to plan, coordinate with other site teams, and carry out testing to verify safety and functionality. This includes mains, lighting, emergency systems, and control equipment.
Certification & Handover
You receive a full pack including EIC certification, test results, cable schedules, and any required Building Regulations documentation.
Professional electrical infrastructure offers far more than basic functionality. When you choose GCL, you benefit from:
Futureproofing – Designs that anticipate future growth in demand, usage, and technology.
Energy Efficiency – Reduced running costs and better environmental performance.
Improved Safety – Elimination of overloaded circuits and legacy hazards.
Long-Term Value – Durable, well-labelled, and accessible installations that are easier to maintain and expand.
As building technology continues to evolve, electrical contracting services must account for both traditional infrastructure and modern smart systems. At GCL, we help businesses prepare for tomorrow with installations that support:
IoT devices and building management systems (BMS)
Smart lighting and occupancy sensors
EV charging points
Remote monitoring and automation
This integration enables greater control, better energy efficiency, and enhanced occupant comfort.
