Commercial Electrical Services

Commercial electrical work, from one hub

Voltnet Engineering Ltd provides electrical contracting for commercial premises, with this page acting as the broad starting point for installations, upgrades, maintenance and testing. We work with offices, retail spaces, warehouses and industrial facilities where the electrical installation needs to support people, equipment and day-to-day operations.

The right scope depends on the property, the existing installation and the work being planned. We can discuss the requirement with a business owner, facilities contact, principal contractor or other project team member before the work is agreed.

Commercial premises and project types

• Office fit-outs, refurbishments and electrical upgrades
• Retail spaces and customer-facing premises
• Warehouses and industrial facilities
• Industrial machinery connections and three-phase power installations
• Ongoing maintenance or a one-off commercial electrical repair

Installations, distribution and power

Commercial installation work can include new electrical infrastructure, upgrades and distribution-board work. The existing service scope also includes three-phase power supplies for commercial and industrial requirements. The design and installation approach should be confirmed against the building, equipment and available supply rather than assumed from the property type.

For office lighting design and upgrades, see the dedicated office lighting service. For structured cabling, fibre termination, network testing and comms-room work, visit the fibre optic networking service so those specialist requirements remain clearly separated.

Fit-outs and refurbishments

Office fit-outs and refurbishments can involve lighting, power, additional points, distribution changes and coordination with other work on site. We can discuss the electrical scope alongside the building programme and identify what needs to be completed, tested or documented for the project handover.

Planned maintenance and reactive support

Commercial maintenance may be planned as preventative work or arranged in response to an electrical fault. The existing maintenance scope includes one-off repairs, annual maintenance contracts, distribution-board inspections, lighting repairs, data-point testing and reactive emergency repairs.

Where a fault affects a business, the first priority is to understand the risk and make the next step clear. Urgent electrical faults have a separate emergency electrician service; this page remains the broader route for planned commercial work and ongoing electrical requirements.

Testing, compliance and documentation

Commercial testing services listed on the site include EICR periodic testing, emergency-lighting testing, PAT testing, fire-alarm servicing and distribution-board inspection. The wider commercial service information references the Electricity at Work Regulations 1989 and BS 7671. The appropriate testing and remedial scope depends on the installation and should be agreed for the project.

See the relevant BS 7671 and inspection/testing qualifications for qualification context.

Testing certificates, schedules, drawings or other handover information should be discussed before work starts so the deliverables are clear. For detailed containment calculations, electrical schematics or as-built records, use the relevant cable-management, schematic or as-built drawing service rather than duplicating those specialist scopes here.

Managing access and disruption

Commercial work is planned around the building, the existing installation and the people using the premises. Access arrangements, work areas, sequencing and coordination with facilities or contractor teams can be discussed as part of the scope. The practical approach depends on the site; no particular working hours or disruption-free outcome is assumed.

Lighting and energy considerations

Energy-efficient lighting upgrades and power-optimisation work can form part of a commercial project. LED upgrades may be suitable, but any energy or cost effect depends on the existing fittings, controls, operating pattern and agreed design. For office-specific layouts, controls and workplace settings, continue to the dedicated office-lighting page rather than treating this broad service page as a lighting specification.
