- Residential, commercial, industrial, or specialized project fit
- Breadth of panels, lighting, power distribution, data, EV charging, solar, generators, and related systems
- Published involvement in planning, construction coordination, permitting, testing, or inspection

What Should Be Confirmed Before Hiring an Installation Contractor?
Define load requirements, drawings, equipment, lighting, future expansion, and schedule. Ask bidders to identify exclusions and responsibility for design, permits, inspections, utility work, trenching, equipment, commissioning, and closeout documents.
Compare written bids using the same scope. Verify licensing and insurance, then document payment milestones, change orders, warranty terms, start dates, and completion conditions.
Frequently Asked QuestionsWhen should an electrical contractor join a new-construction project?
Early design involvement can help align service capacity, panels, circuits, lighting, data, HVAC loads, EV charging, and future expansion before walls are closed. Ask the architect, builder, and electrician to define responsibilities.
Does every new electrical installation require a permit?
Permit requirements depend on the work and jurisdiction. New services, panels, permanent wiring, EV chargers, generators, solar systems, and tenant improvements may require permits or inspections. Confirm requirements with the local authority and contractor.
What should a new-installation estimate include?
Look for the equipment and labor scope, materials, fixtures, permit responsibility, utility coordination, testing, inspections, exclusions, schedule, payment terms, change-order process, and written warranty terms.
Can one electrician handle solar, EV charging, generators, and building wiring?
Some contractors publish all of these capabilities, while others specialize. Confirm licensing, relevant experience, equipment qualifications, design responsibility, and whether any portion will be subcontracted.
