What sets Cessnock apart

Built for the coalfields

Land settlement tied to the coalfields between 1903 and 1923 set the town's pattern. Council's heritage guidelines say the two-storey, single-fronted house with a full-height verandah is found here in greater numbers than anywhere else in NSW.

Asbestos was a building material

Council's guidelines note that 1930s and 1940s brick bungalows had gable ends finished in timber shingles, white painted asbestos cement and timber battens.

Plenty of renters

In the suburb of Cessnock, 37.7% of homes were rented at the 2021 Census and 84.1% were separate houses.

Heat and frost

Cessnock Airport's January mean maximum is 30.6 °C and its record is 46.8 °C, while winter nights can be frosty. Air conditioners and heaters work hard here.

Coal under the ground

Subsidence Advisory NSW lists districts named Bellbird-Millfield, Greta and Tomalpin. Building or extending inside one needs its approval first.

The jobs Cessnock homes need

Switchboards in older houses. A dark, tar-like backing board made before 1987 can contain asbestos, and some old fuses on those boards may hold friable asbestos inside the carrier. A switchboard specialist knows how to work around it, or when a licensed removalist has to come first. More on asbestos switchboards.

Cooling and heating circuits. A big split system or several heaters on one old circuit is a common reason the power trips on the hottest and coldest days. A dedicated circuit usually fixes it, once the electrician has checked the board can carry the extra load.

Rental repairs. Landlords with older houses need faults fixed quickly and on paper. In NSW the electrician lodges a CCEW within 7 days of finishing, even for a like-for-like swap.

Black or crumbly board behind your meter?

Don't drill, screw or scrape it. NSW says pre-1987 bituminous boards may carry names like Zelemite or Lebah on the back, and a warning sticker may be inside the meter box. Leave it to a licensed electrician to assess, and to a licensed asbestos removalist if it has to go.

What we would do in Cessnock

Before summer, have the switchboard checked and give the main air conditioner its own circuit if it doesn't have one. If the board sits on an old dark panel, plan the upgrade around the asbestos from the start rather than finding out halfway through the job.

Questions

Straight answers.

What should a Cessnock rental condition report say about the electrics?

NSW Fair Trading recommends noting visible hazards such as loose or damaged power points, loose wiring and sparking power points. The report also records whether there's a safety switch and whether it works, which only a test confirms.

We're on acreage near the bush. What should we ask an electrician?

Ask who owns the pole and line from the road. Ausgrid says owners are responsible for private poles and lines beyond its connection point, and it patrols them in bushfire prone areas. Repairs to them are work for a Level 2 Accredited Service Provider.

Who looks after the power lines in Cessnock?

Ausgrid, which runs the network across the Hunter Valley. Report outages and fallen wires on 13 13 88, and remember the Black Christmas fires of 2001 began partly in this area: treat any line on the ground as live.
