Frequently Asked Questions
What is three-phase power?
Three-phase is a more powerful electrical supply using three live conductors instead of one. It delivers roughly three times the power of single-phase (typically 60-70A per phase vs 80-100A single phase). It's essential for high-demand commercial, industrial, and agricultural applications.
How much does a three-phase installation cost?
Three-phase consumer unit installation starts from £1,500 plus VAT. The total project cost depends on the DNO application fee (£800-£3,000+), cable run distance, and equipment requirements. We handle the full process including DNO liaison and commissioning.
Can I get three-phase at home?
Yes, if you need it for EV rapid charging, workshop equipment, or high-demand appliances. You'll need to apply to your DNO (Western Power Distribution in Devon). The process takes 6-12 weeks. We manage the entire application and installation.
Do you handle the DNO application?
Yes, we manage everything: the application to Western Power Distribution, site surveys, metering arrangements, consumer unit installation, and final commissioning. You don't need to deal with the DNO directly.
