New Build & Refurbishment
Commercial Electrical Installation
First and second fix commercial electrical installations for new builds, refurbishments, and fit-outs — delivered to BS7671 and fully certified.
Commercial electrical installations done right, first time
From ground-up new builds to full-scale refurbishments and distribution board upgrades, MAC Electrical delivers commercial electrical installations that meet the latest 18th Edition Wiring Regulations (BS7671). We understand the pressures of construction programmes and work closely with main contractors, project managers, and architects to hit deadlines without cutting corners on quality or safety. Our team handles everything from first-fix containment and cabling through to second-fix wiring, testing, certification, and final commissioning. All works are completed by fully qualified electricians, and every installation is signed off with the appropriate certificates and documentation for building control and end-user records.
