Electricians in Seven HillsNext door to a knockdown-rebuild.

Walk a Seven Hills street south of the railway and you'll often pass a small mid-century house beside a two-storey rebuild with two to three times the floor space. Those two homes need very different electrical work. 35.3% of homes here are rented, so landlords are a big part of the picture.

Seven Hills, house by house

The originals

Mid-20th century single-storey homes of mixed construction, about 100 square metres on 600 to 900 square metre blocks.

The rebuilds

Two-storey brick veneer homes from the 2000s have replaced many of them, especially south of the railway.

Land given to new suburbs

From 1959 to the 1970s, housing schemes took Seven Hills land to create Lalor Park and Kings Langley.

Endeavour Energy

Seven Hills is split between Blacktown and Parramatta councils, both in Endeavour's area. Faults: 131 003.

Industry to the north

A large industrial and commercial area runs north of the railway line.

What we'd suggest

In an original Seven Hills house you plan to keep, upgrade the switchboard before adding anything big. If you're knocking down to rebuild, skip that and ask the builder's electrician to size the new board for a charger and battery from day one. For either, we'll match a licence-checked local who does the work if we have one.

Questions

Straight answers.

I rent out a Seven Hills house. What do I have to keep on top of?

Smoke alarm checks every year, electrical faults handled as urgent repairs, and a CCEW kept for each job. A hardwired smoke alarm must be repaired by a licensed electrician.

Who handles the power connection for a knockdown-rebuild?

Work on the service line and energising the new connection are jobs for a Level 2 Accredited Service Provider. Individual ASP workers also need authorisation from the local distributor, here Endeavour Energy.
