About this service
Commercial electrical installation provides new distribution, power, lighting, controls and equipment supplies for a business premises. It can range from a new circuit to a complete installation, but every scope should start with load, layout, fire strategy, building services and future use.
Containment and distribution should remain accessible and understandable after handover. Short-term savings from undersized trunking, crowded boards or poor labelling tend to become maintenance costs later.
Common problems we help with
Tenant requirements differ from the base build
Additional power, data, lighting and equipment supplies are needed before occupation.
Existing distribution has limited ways
New loads may require a board alteration, sub-distribution or supply review.
Containment clashes with services
Ceiling, ventilation, sprinklers and structural constraints need coordination before installation.
Future churn is not considered
Offices and retail layouts change, so accessible routes and flexible circuiting are valuable.
How we carry out the work
Develop the electrical scope
Loads, plans, equipment, landlord requirements and handover information are agreed.
Install distribution and containment
Cables, boards and routes are coordinated with the building programme and other services.
Second fix, test and document
Accessories and equipment are connected, circuits verified and schedules or drawings updated.
What is normally included?
- Initial discussion about the property, symptoms, priorities and timescale
- Assessment of the relevant circuit, equipment, access and existing protection
- A written scope for the proposed commercial electrical installation work
- The agreed installation or repair work, with disruption kept to a reasonable minimum
- Inspection, electrical testing and appropriate handover documentation
Before the work starts
- Operational loads, critical equipment and permitted shutdown windows
- Existing drawings, circuit schedules and maintenance records
- Access, permits, occupied areas and coordination with site management
- Future capacity, maintainability and business-continuity requirements
What affects the price?
The price depends on the existing installation and the amount of work required. For commercial electrical installation, the main factors normally include:
- Load, circuit and distribution complexity
- Containment, access equipment and working restrictions
- Phasing, temporary supplies and out-of-hours work
- Testing, documentation and coordination with specialist equipment
Testing, certificates and handover
Once the installation work is complete, we inspect and test it and provide the records that apply to the job.
- Updated labels, schedules and relevant drawings
- Installation or test certification
- Operating and isolation information
- A documented list of agreed variations and remaining recommendations
Commercial Electrical Installation questions
Can you work from an interior designer’s plan?
Yes, but equipment loads, technical details and a defined electrical scope are also required.
What drawings will we receive?
The handover requirement should be agreed. It may include board schedules, marked-up plans and test documentation.
Can areas be handed over in phases?
Yes, where distribution, testing and temporary interfaces are planned safely.
