Electrical Services for Businesses in Cobham & Surrey
Commercial electrical work requires a different approach to domestic installations. Larger loads, three-phase supplies, emergency lighting systems, fire alarm integration, and the need to minimise business disruption all demand an electrician with specific commercial experience.
At Cobham Electrical Contractors, we provide the full range of commercial electrical services — from complete office fit-outs and retail installations to periodic testing, emergency lighting certification, and ongoing maintenance contracts. We work with businesses of all sizes across Cobham, Weybridge, Esher, Guildford, and the wider Surrey area.
We understand that downtime costs money. That's why we schedule work around your business hours, provide accurate timelines, and complete every job on schedule. For retail and hospitality clients, we routinely carry out installations during evenings and weekends to avoid disruption.
Every commercial installation is fully compliant with BS 7671, the Electricity at Work Regulations 1989, and relevant fire safety regulations. You receive complete documentation for your compliance files.

The Cost of Unreliable Commercial Electrics
For businesses, electrical problems don't just create inconvenience — they create liability, lost revenue, and regulatory risk. The consequences of neglecting commercial electrical maintenance are significant:
- Non-compliant installations put you in breach of the Electricity at Work Regulations 1989 — a criminal offence with unlimited fines
- Failed emergency lighting puts occupants at risk during evacuations and violates fire safety regulations
- Power outages during trading hours mean lost revenue, spoiled stock, and frustrated customers
- Outdated wiring cannot handle modern commercial loads — servers, EPOS systems, commercial kitchens, and air conditioning
- Insurance claims can be rejected if the electrical installation lacks current certification
- Staff and customer safety is compromised by untested or deteriorating electrical installations
Our Commercial Project Process
Site Survey & Scope
We visit your premises to understand the electrical requirements, assess the existing installation, and discuss your operational constraints. We identify the scope of work and any specific challenges — access restrictions, trading hour limitations, or phased installation requirements.
Detailed Proposal
You receive a comprehensive proposal including scope of work, materials specification, timeline, and fixed pricing. For larger projects, we provide phased timelines with clear milestones. No hidden costs, no surprises.
Scheduled Execution
We carry out the work according to the agreed schedule, coordinating with your team and other trades as required. For occupied premises, we minimise disruption and maintain power to critical systems throughout.
Testing & Commissioning
All installations are tested to BS 7671 standards. Emergency lighting is commissioned and tested. Distribution boards are labelled and documented. Every circuit is verified before handover.
Documentation & Compliance
You receive full electrical certification, test results, emergency lighting certificates, and any other documentation required for your compliance files. We register the work with NAPIT and provide ongoing support.

Commercial Electrical Services — Scope and Standards
Commercial electrical installations differ from domestic work in several important ways. Three-phase power distribution is common in larger premises, requiring specific expertise in phase balancing, motor control, and high-current protection. We design and install three-phase distribution systems for offices, kitchens, workshops, and server rooms.
Emergency lighting is a legal requirement in all commercial premises under the Regulatory Reform (Fire Safety) Order 2005. Systems must be designed to provide adequate illumination for safe evacuation in a power failure, tested monthly and annually, and maintained in accordance with BS 5266. We design, install, commission, and maintain emergency lighting systems across Surrey.
Fire alarm integration is another critical element of commercial electrical work. We install fire alarm circuits, interface with alarm panels, and ensure that electrical installations do not compromise fire compartmentation. All work is coordinated with your fire alarm contractor.
Office fit-outs require careful planning of power and data infrastructure. We install floor boxes, perimeter trunking, dado trunking systems, and ceiling-mounted power tracks to provide flexible, accessible power and data points throughout the workspace. Layouts are designed to accommodate future changes in furniture arrangement.
Retail and hospitality premises have specific requirements for lighting design (high CRI fittings for product display), EPOS power supplies (clean, dedicated circuits for sensitive equipment), and exterior signage power supplies. We work with fit-out contractors and design teams to deliver installations that meet both the aesthetic and technical requirements.
Periodic inspection and testing of commercial installations is required under the Electricity at Work Regulations 1989. The recommended frequency depends on the type of premises — typically every 3 years for commercial offices and retail, every year for construction sites and swimming pools. We carry out commercial EICRs and provide clear, actionable reports.
We provide commercial electrical work services across Cobham, Weybridge, Esher, Oxshott, Walton-on-Thames, Dorking, Godalming, Guildford, and the wider Surrey area. Read our customer reviews or view examples of our work.
