FAQ

Frequently Asked Questions

Common questions about 3-phase electrical installations

3-phase power provides three alternating currents, allowing for more efficient power distribution and the ability to run high-power equipment. You typically need it for commercial premises, workshops with heavy machinery, commercial kitchens, large HVAC systems, or any equipment rated above 7.5kW.
We handle the entire process for you. First, we assess your power requirements and submit an application to your electricity supplier (DNO). Once approved, we install the service head, 3-phase meter, and distribution equipment. The process typically takes 4-8 weeks from application to completion.
Costs vary depending on whether you need a new supply from the DNO (typically £2,000-£5,000+ for the connection) plus our installation costs for the distribution equipment (£1,500-£4,000+). We provide detailed fixed-price quotes after assessing your specific requirements.
Yes, we regularly upgrade single-phase supplies to 3-phase. This involves applying to your DNO for the upgrade, installing a new service head and meter, and upgrading your distribution equipment. We handle all aspects including liaison with your electricity supplier.
Once DNO approval is received, the physical installation typically takes 2-5 days depending on complexity. This includes installing the service equipment, distribution boards, sub-mains, and all associated wiring. We plan installations to minimize disruption to your business operations.
Yes, we offer comprehensive maintenance contracts for commercial electrical installations. This includes periodic inspection and testing, thermal imaging surveys, and emergency callout services to ensure your 3-phase system remains safe and compliant.
