Separate Metering Cost Estimator
Ballpark electrical connection costs for a granny flat with its own meter or sub-board.
Metering questions
Do I need a separate meter for a granny flat rental?
Not always legally, but a separate meter (or sub-meter arrangement) makes billing tenants fair and can simplify tax records. Check your state tenancy rules and speak with a level-2 ASP electrician about the cheapest compliant setup for your block.
What affects metering cost the most?
Distance from the main switchboard, trenching, switchboard upgrade capacity and whether the network operator requires a new service connection all move the price. Long runs to a detached rear flat cost more than a sub-board in the same building.
