Granny flat wiring — Canning Vale and SE Perth
Rear units, extensions, multi-gen households. Done properly so the granny flat doesn't pull power from the main house every time someone runs the kettle out the back.
Multi-gen is normal here
Half my Canning Vale, Harrisdale and Southern River jobs are multi-generational. Granny flats out the back for ageing parents. Side extensions for adult kids. Sometimes a fully separate dwelling on a sub-board with its own meter.
It's a whole electrical sub-genre — and most generic-Perth electricians don't have the routine for it. I do.
What granny-flat wiring includes
Quoted as one job, done as one job
Sub-board install, RCD sizing for the new circuits, lighting and power runs, smoke alarm interconnect across both buildings. You get a complete electrical setup that doesn't compromise the main house.
About separate metering
If you need billing split between dwellings, I can set up provision for a separate meter. This is common when renting the granny flat out or when you want clear cost separation.
The decision depends on your situation — I'll tell you what makes sense for your setup and what Western Power requires.
