Plan while there is still safe, dry access

Before the rainy season, write down the electricity account details, the utility contact channel and the building management number. Save them on a phone and keep a paper copy with essential documents. In a rented home, agree who will contact the landlord and arrange an electrical inspection.

Identify which equipment sits near floor level and which items are essential for a household member. Photograph model and serial labels in advance. This helps with servicing and insurance records without needing to handle damaged equipment later.

Follow official advice about switching off the supply before water enters, but only while the switch is safely accessible from a dry location. Do not open electrical covers or attempt wiring work. If water has already reached the area, withdraw and contact the utility or emergency services.

Once water is present, change the plan

A familiar route through the kitchen can become unsafe when sockets, extension leads or appliances are wet. Do not wade in to unplug something, retrieve a charger or operate the main switch. Follow evacuation instructions instead of finishing a household checklist.

Keep children and other household members away from affected rooms. Do not assume an appliance is safe because its casing looks intact. The Energy Commission warns about electrical hazards during and after floods; insulation and normal appearance are not a substitute for assessment.

Separate returning home from restoring electricity

Permission to return to a neighbourhood is not approval to turn on every circuit in a house. Tell the inspecting electrical contractor which rooms flooded, how high the water reached and whether the supply was isolated. Include sockets, wiring and the distribution board in the discussion, not just large appliances.

Ask what can be restored, what must remain isolated and what work is still outstanding. Keep the written findings. For a condominium, also check whether building management has restrictions affecting lifts, common electrical rooms or service access.

Keep a record instead of trying a test run

Do not plug in flood-affected appliances to see whether they still work. Dry-looking surfaces do not reveal the condition inside a motor, control board or cable connection. Contact the manufacturer or an authorised service provider and disclose the water exposure.

Make a simple list: item, model, water exposure, service reference and decision. Photograph damage only when safe. Ask the insurer whether an assessment is needed before disposal; keep unsafe items clearly separated so another person does not reconnect them.

Repair suitability depends on the damage and the equipment. A cleaning cycle, sunlight or a few days of drying is not electrical clearance.

Give everyone the same restart instructions

Before normal routines resume, tell everyone which outlets and appliances are cleared for use and which are not. Keep any contractor restrictions with the equipment. Arrange follow-up work rather than relying on a verbal reminder that can be forgotten.

Prepare drinking water as well as an electrical safety plan. Our water-disruption checklist covers storage and supply arrangements.

Frequently asked questions

Can I switch the main supply off after water enters?

Do not enter water or approach wet electrical equipment to operate a switch. Stay away and seek help from the electricity utility or emergency services.

Can an appliance be used once it feels dry?

No. External dryness does not establish electrical safety. Keep flood-affected appliances disconnected until assessed by an appropriate service professional.
