Granny Flat Electrical in Sydney

A granny flat or secondary dwelling needs power that's safe, compliant and — where it's rented — separately metered. Sydney Power Group (SPG) is a Level 2 ASP authorised across Ausgrid, Endeavour Energy and Essential Energy, so we can handle the mains, metering and any connection work the network side requires.

The first question on most granny flat jobs is capacity: can the existing supply carry a second dwelling, or is an upgrade needed? SPG assesses this up front and delivers the right supply solution before your build gets ahead of it.

Sub-Metering or Separate Supply

If the granny flat is for family, a shared supply with a private sub-meter is often enough. If it's tenanted, a separate metered supply may be required so the occupant is billed directly. SPG advises on the right approach and installs the smart metering to match.

Where a dedicated supply is needed, we run new consumer mains and arrange the network connection — Level 2 ASP work that SPG performs across all three NSW networks.

Checking Mains Capacity

Adding a dwelling can push an older supply past its limit. We check the existing consumer mains and switchboard, and where they can't carry the extra load we arrange a supply upgrade or switchboard upgrade so the whole property stays safe.

For larger dual-living projects, compare setups on our duplex and new homes pages.

Ready When Your Build Is

We coordinate supply and metering around your construction timeline so the granny flat can be energised without holding up the main dwelling or the tenant move-in.
