Commercial Electrical Installation

Commercial Electrical Expertise You Can Rely On

Commercial electrical installations are significantly more complex than domestic work. They typically involve larger supplies, three-phase distribution, commercial-grade distribution boards, more demanding environmental conditions, and the need to work around business operations to minimise downtime. They also carry greater regulatory responsibility: commercial properties must comply with BS 7671, the Electricity at Work Regulations 1989, and in many cases sector-specific requirements relating to fire alarm systems, emergency lighting, and health and safety provisions.

JR Electrical Services has experience across a wide range of commercial premises including offices, retail units, restaurants, warehouses, light industrial facilities, schools, and healthcare settings. We work directly for business owners and facilities managers as well as for main contractors and fit-out companies. Whatever the scope — from a single tenancy fit-out to a larger multi-floor installation — we plan the work carefully, communicate proactively with all parties, and deliver to the agreed programme.

We understand that commercial clients need more than just technical competence. You need a contractor who turns up on time, works safely and tidily in occupied or partially occupied premises, and completes the job to the standard required by the building's certifying authority. All commercial installation work we carry out is tested and certified to BS 7671, and we provide the full documentation needed for building sign-off.
