About GCL – Commercial Electrical Contractors

Technical Precision. Trusted Delivery. Infrastructure That Lasts.

We’re GCL — a team of experienced commercial electrical contractors and data infrastructure specialists, trusted by organisations across the UK. Our work spans university campuses, clinical spaces, and large commercial sites where reliability, safety, and compliance are non-negotiable.

Established in 1997, we bring over 25 years of hands-on experience in designing and delivering electrical systems, structured data cabling, enterprise-grade WiFi, and scalable battery storage. As a result, clients rely on us for full-site upgrades, new build installations, and technically complex projects in live environments.

In addition, we’re fully accredited by NICEIC, ECA, and SafeContractor, and all engineers are DBS-cleared. We also follow rigorous testing and certification standards to ensure complete peace of mind.

Whether we’re upgrading a main distribution board, installing LED lighting, or deploying a new WiFi network, our goal is simple: do it once, do it right.

We work closely with consultants, contractors, and end clients to ensure a smooth delivery from concept through to commissioning. As trusted commercial electrical contractors, we also bring flexibility, clear communication, and a practical understanding of working in sensitive or high-security sites.

A Word From Our Director

“Clients trust us because we make technical projects feel straightforward. We turn up when we say we will, we do the job to spec, and we leave sites better than we found them. That’s what good contracting should look like..”
