Renovating a cottage in Thirroul, Austinmer or Bulli: electrical checklist

The northern suburbs are full of character cottages being brought into the modern day. The electrics are usually the part that needs the most work, and the part that's cheapest to get right before the walls are closed up.

We service a large area including Wollongong, the Illawarra and Shoalhaven regions, including Nowra, Kiama, Helensburgh & surrounding regions. See all areas we cover

Bring the electrician in early

Get your electrician through the house before the builder locks in the plan. Old cottages often need a switchboard upgrade before they can take a new kitchen, air-con or an induction cooktop, and that changes the budget.

Plan for salt air

Close to the beach, salt gets into everything. Outdoor lights, power points and fittings should be rated for the conditions, ideally marine-grade or high IP rated, with stainless fixings.

Steep blocks and long runs

Escarpment blocks often mean a long run to a studio, garage or pool at the bottom of the yard. Cable size matters on long runs, so tell your electrician early if you're planning a backyard building.

Think about how you'll use each room

  • A home office: data points and plenty of outlets at desk height.
  • Bedrooms: power and USB outlets beside the bed.
  • Kitchen: dedicated circuits for the oven, cooktop and dishwasher.
  • Outdoor living: weatherproof power and lighting on its own circuit.

Don't forget smoke alarms

A renovation is the perfect time to install interconnected smoke alarms, so when one goes off they all do.
