ENDEAVOUR THREE-PHASE UPGRADE

Upgrading from single-phase to three-phase supply on the Endeavour Energy network gives your property the capacity for modern high loads — EV charging, ducted air conditioning to handle the Western Sydney heat, pool equipment, sheds and workshops. Sydney Power Group manages single-to-three-phase supply upgrades across the Endeavour supply area, from application to energisation.

The Payoff of Three-Phase Power

Single-phase supply struggles with today's combined loads. Three-phase spreads the load, reduces voltage drop and supports fast EV charging, ducted systems and large appliances — in high demand across renovated homes and the semi-rural Hawkesbury and Camden properties running sheds, bores and irrigation pumps. Endeavour will confirm three-phase is available in your street before we proceed. See our supply upgrade service.

Steps From One Phase to Three

A three-phase upgrade usually requires new three-phase consumer mains, a switchboard upgrade and often metering changes. We coordinate the network application with Endeavour, install the mains and metering, book the isolation, and re-energise on three phases — all under one job.

Pricing a Three-Phase Conversion

Cost depends on the mains run, switchboard condition and whether the service is overhead or underground — a rural block needing a longer three-phase run and a new pole span sits at the higher end. We quote clearly up front. For context read our Level 2 electrician cost guide.
