The Electrical Contractor Behind the Build
The electrical installation is the foundation of any commercial building — power that can't support the load, lighting that fails lux requirements, emergency systems that don't pass inspection: these aren't cosmetic problems, they're project-stopping ones.
Wired Weston delivers commercial electrical installations that are designed correctly from day one — load-calculated, properly contained, compliant with current standards, and fully certified at handover. We work directly with business owners, developers, and main contractors across Somerset and Bristol, bringing the same technical rigour to a small retail unit as to a large warehouse or multi-unit development.
Commercial Electrical Services
We cover every electrical discipline a commercial project requires — from the incoming supply through to final test and certification.
Power Distribution & Panel Installations
Incoming supply design, main distribution boards, sub-boards, and three-phase installations for high-demand commercial loads. Accurate load scheduling and cable sizing to BS 7671.
Commercial Lighting Design & Installation
Lux-level design and installation of LED commercial lighting for offices, retail, warehouses, and food production — including high bay fittings, track lighting, and recessed panels.
Emergency Lighting Systems
BS 5266-1 compliant emergency lighting design, installation, and certification. Escape route coverage, open area lighting, and maintained or non-maintained systems with annual test scheduling.
Data & Communications Cabling
Structured cabling for data networks, phone systems, and AV distribution. Cat6/Cat6A copper, containment routing, patch panel termination, and BS EN 50173 certified testing.
Sub-Metering & Energy Monitoring
Individual metering for multi-occupancy buildings and mixed-use premises. Enables independent billing per unit and supports energy management reporting for commercial landlords.
Steel Containment & Cable Management
Design and installation of cable tray, trunking, and ladder systems in line with fire compartmentation requirements and BS 7671. Integral to any new build or major commercial refurbishment.
Retail, Catering & Bakery Electrical
Complete electrical installations for retail units, restaurants, and food production bakeries — three-phase cooking circuits, refrigeration supplies, EPoS power, and compliant lighting.
Contactor Controls & Automation
Lighting control panels, contactor switching, photocell automation, and time-clock scheduling for warehouses, car parks, and commercial exteriors — reducing energy waste significantly.
Electrical Compliance & EICR
Periodic Inspection & Testing (EICR) for commercial premises, alongside Electrical Installation Certificates and O&M documentation at project handover. Full BS 7671 compliance sign-off.
Commercial Electricians You Can Build Around
The electrical installation is not a finishing trade — it runs through every phase of a commercial project and touches every other discipline. First-fix containment must be in before the suspended ceiling goes up. The distribution board specification determines what loads can be added later. Emergency lighting placement is governed by escape route geometry, not aesthetics. Getting these decisions right at the design stage is what separates a clean handover from a snagging list.
We produce accurate project estimates with full bill of materials, cable schedules, and load calculations before work begins — giving main contractors and business owners a clear picture of scope, cost, and programme impact. Our engineers attend site to coordinate with other trades, adapt to changes on the fly, and keep the installation on programme.
On completion, we issue full Electrical Installation Certificates, test schedules, emergency lighting commissioning records, and as-built drawings — the documentation package your building control officer and insurer expect to see. Every commercial installation we deliver is NICEIC inspected and ECA registered, which means our certification carries weight.
We also serve domestic clients to the same technical standards applied on commercial sites. Our domestic electrical services and house rewiring are delivered by the same qualified engineers who work on commercial jobs.

Why Commercial Clients Choose Wired Weston
Commercial electrical projects demand technical precision, programme discipline, and complete documentation. Here is how we deliver that on every job.
Accurate Estimates
Itemised quotes with labour, materials, and programme schedule produced before work begins — no surprises mid-build.
Programme Committed
RAMS, site inductions, and phased installation sequences managed without chasing. We hit your dates.
Full Compliance Pack
EIC certificates, test schedules, emergency lighting records, and as-built drawings issued at handover as standard.
Direct Engineer Access
You deal directly with our engineers — decisions made on site, fast. No account handlers or management layers.
Electrical Safety & Compliance
Commercial electrical installations carry greater compliance obligations than domestic work. Failure to meet current regulations — BS 7671, BS 5266, the Electricity at Work Regulations 1989, and the Regulatory Reform (Fire Safety) Order 2005 — creates liability for building owners, landlords, and employers.
Every installation we deliver is designed to meet these obligations from the outset. We provide the certification, test records, and documentation that demonstrate compliance to building control, insurers, and enforcement authorities — so you are not left exposed after the job is done.
Commercial Electrical FAQ
Common questions from business owners, commercial developers, and main contractors.
We deliver the complete electrical package for commercial premises — incoming power distribution, three-phase installations, sub-boards and consumer units, commercial lighting design and installation, emergency lighting to BS 5266, data and communications cabling, contactor controls, sub-metering, and full BS 7671 certification. We also handle ongoing maintenance, periodic inspection, and fault finding after handover.
Yes. We provide full design-and-install delivery — producing cable size calculations, load assessments, single-line diagrams, and technical specifications to IET Wiring Regulations (BS 7671). This documentation satisfies main contractor requirements, M&E consultant reviews, and building control submission.
Yes. Three-phase power is essential for high-demand commercial loads — large catering equipment, bakery ovens, HVAC plant, industrial machinery, and multi-circuit distribution boards. We design and install three-phase incoming supplies, main distribution boards, and sub-boards sized accurately to your load schedule.
Emergency lighting must comply with BS 5266-1 and the Regulatory Reform (Fire Safety) Order 2005. We carry out a site survey to determine emergency lighting categories, design the system to cover escape routes and open areas, install self-contained or centrally monitored luminaires, and issue a completion certificate with test records. Annual testing and maintenance can also be arranged.
Yes. We install structured cabling systems for data networks, telephone systems, and AV distribution — including Cat6/Cat6A copper cabling, containment routing, and patch panel termination. All cabling is installed to BS EN 50173 and tested with certification on completion.
Sub-metering installs individual electricity meters on each unit within a multi-occupancy building — essential for converted properties with multiple flats or mixed-use buildings with retail units and residential above. It enables independent billing per occupant and is a legal and commercial requirement for landlords of multi-occupancy premises.
All commercial installations are designed and installed to BS 7671 (18th Edition Wiring Regulations) and the relevant British Standards for each system — BS 5266 for emergency lighting, BS EN 50173 for data cabling, and BS 5839 for fire detection where applicable. On completion we issue Electrical Installation Certificates (EICs), test schedules, and O&M documentation. We are NICEIC approved and ECA registered, so our certification is accepted by building control and insurers.
Absolutely. We are experienced at working within a wider construction programme — producing RAMS, attending site meetings, coordinating with M&E consultants and structural engineers, and hitting programme milestones. You deal directly with our engineers, which means faster decisions and no miscommunication through layers of management.
