Electrical & containment

Mottram Installation Group provides high-quality electrical and containment installations designed to support broadcast, data, and security infrastructure across commercial, industrial, and technical environments. Our team delivers precision-built containment systems and electrical works that ensure safety, serviceability, and long-term performance on every project.

We design and install containment solutions tailored to complex cabling and power environments — from multi-discipline technical rooms to large-scale data halls. Every installation is carefully planned for accessibility, separation, and load capacity, ensuring compliance with both client specifications and BS 7671 standards.

Our capabilities include:

• Cable tray, trunking, and basket systems (steel, PVC, and stainless)
• Ladder racks and multi-tier containment systems
• Underfloor and overhead containment for technical areas
• Fire-rated and segregated containment for power and data separation
• Precision marking, routing, and labelling for future serviceability

Containment layouts are coordinated in advance with other trades and services, reducing clashes and enabling efficient programme delivery.

We undertake a full range of electrical works to support both standalone and integrated system installations, including:

• Power distribution boards and sub-circuits for technical and office areas
• Final circuit wiring for broadcast, data, and security equipment
• Energy-efficient lighting and emergency lighting systems
• Earthing, bonding, and surge protection
• Commissioning, inspection, and certification to BS 7671

All electrical installations are completed by qualified personnel, tested with calibrated instruments, and issued with formal NICEIC-compliant certification where required.

Our focus is on delivering clean, well-routed containment and reliable electrical installations that complement our wider technical disciplines. Every installation follows strict safety protocols, controlled quality inspections, and coordinated documentation.

Benefits include:

• Neat, labelled containment with full accessibility for maintenance
• Reduced rework through coordinated cable pathways
• Improved safety and compliance across electrical and low-voltage systems
• Integration-ready solutions for broadcast, data, and security equipment

Where possible, electrical assemblies and containment brackets are prefabricated within our Essex workshop. This reduces site time, improves consistency, and allows for faster deployment — ideal for projects with restricted access or live broadcast environments.

• Proven expertise in technical and commercial electrical installations
• Coordinated containment and cabling for integrated systems
• Full compliance with BS 7671 and current IET Wiring Regulations
• Experienced in live, high-security, and critical environments
• Complete documentation, test certification, and quality assurance
