Sydney suburbs

Electricians across the HawkesburyFlood plains, bushland and Endeavour Energy.

If your Hawkesbury home has been flooded, the power doesn't simply come back on. Endeavour Energy disconnects homes it suspects are flood-damaged, a licensed electrician has to inspect and repair the wiring and lodge a certificate, and then you call Endeavour on 131 003 to reconnect. Here's how that works, and what else this part of Sydney asks of your wiring.

Floodwater in the house: leave the power off

If you're asked to evacuate, switch off at the main switch if it's safe to do so. Don't use appliances or touch wet electrical gear until the home is dry and a licensed electrician has checked it. Keep at least 8 metres from damaged or fallen lines and report them to Endeavour Energy on 131 003. For flood rescue, call the SES on 132 500, and 000 if life is in danger.

Getting a flooded home reconnected

  1. Endeavour inspects first

    After the March 2022 floods, Endeavour did a preliminary check and disconnected suspected flood-damaged homes at the meter box or at the pole or pillar.

  2. You engage a licensed electrician

    Endeavour says arranging the inspection and repair of the internal wiring is the property owner's responsibility.

  3. The electrician lodges a CCEW

    After repairs and testing, they lodge a Certificate of Compliance for Electrical Work with Endeavour Energy.

  4. You call for reconnection

    Once the home is safe, phone Endeavour on 131 003 to have it reconnected.

The Hawkesbury's risks

Floods are a fact of life

The NSW RFS says most of the Hawkesbury's urban area is prone to at least a 1 in 100 year flood, worst in Windsor, Richmond, North Richmond, Wilberforce and Pitt Town. The March 2021 flood peaked at 12.9 metres AHD at Windsor, and the 1867 flood reached 19.7 metres.

Big recent floods

In March 2021 Endeavour cut power for safety to about 1,000 low-lying homes along the Hawkesbury and Colo rivers. In March 2022 the river at Windsor rose higher again, and about 1,700 customers were isolated for flood safety.

Fire too

The RFS says the district averages 265 bush fires a year, with a season from October to March.

Mostly Endeavour Energy

Points we tested at Windsor, Richmond, Pitt Town, Wilberforce, Kurrajong, Bilpin and St Albans fall outside Ausgrid's area. The Wisemans Ferry area falls inside it, so check your bill.

Houses, and plenty of renters in town

86.8% of the City of Hawkesbury's 23,060 occupied homes were separate houses in 2021. In Windsor 41.6% were rented, and in Richmond 44.1%.

Before the next flood or fire

Know where your main switch is and that the whole household can reach it. If outbuildings, pumps or sheds sit low on the block, ask an electrician whether their circuits can be isolated separately, so you can keep the house running while the low ground is off.

Before the water comes up

We'd sort out the electrician before the flood, not after it, because every flooded home on the river needs one at the same time. Ask a licence-checked local sparky who does flood reconnections to look at your board now. Tell us your suburb and we'll match you with one.

Questions

Straight answers.

Can I switch my power back on once the water's gone?

No. If Endeavour has disconnected you, a licensed electrician has to inspect and repair the wiring and lodge a CCEW before Endeavour reconnects. Even if it hasn't, don't use anything that got wet until it's checked.

Who pays for the electrician after a flood?

Endeavour says engaging the electrician is the property owner's responsibility. Check your insurance policy for what it covers.

Is the whole Hawkesbury on Endeavour Energy?

Most of it. Around Wisemans Ferry, Ausgrid's network boundary takes over, so check your bill for your distributor.
