Power surges and outages after storms

Storms can cause power surges and outages that damage appliances and trip safety switches. If the power doesn't come back properly after a storm, or a safety switch won't reset, have an electrician check the installation.

The age and construction of a home can affect power surges and outages after storms. A 1950s–60s post-war fibrous-cement house can present different issues from an older or newer one, so it's worth telling an electrician when your home was built. Components nearing the end of their service life often fail together — when one part goes, related parts may not be far behind.

Read this end-to-end if you're planning preventive action, or skip to the warning-signs and cost sections if you are already dealing with power surges and outages after storms right now and need to make a quick, well-informed decision about engaging an electrician.

Why it happens

Storms bring lightning, strong winds and falling branches that can damage overhead powerlines and network equipment. Faults and lightning strikes can send voltage surges into homes through the mains supply, ranging from small spikes that upset electronics to severe surges that damage appliances, inverters and smart devices. Outages and the moment power is restored can also trip safety switches and stress sensitive equipment.

Warning signs

If you are seeing any of the indicators below, treat them as the early stage of power surges and outages after storms rather than waiting for an obvious failure:

• Frequently tripping circuit breakers
• Sparking power points or switches
• Flickering or dimming lights
• Burning smell from switchboard
• Warm or discoloured power points
• Safety switch that won't reset

If any of these patterns sound familiar, don't wait for the next storm season or heatwave to force the issue. Ask for an assessment and a written quote before any work starts, and check whether the inspection itself is charged.

What happens if you leave it

The risk of leaving power surges and outages after storms alone is that the conditions behind it don't pause. Clay soils keep moving, the seasons keep cycling, storms keep arriving — and the problem keeps developing alongside them. The cost curve can be steep: dealing with it early usually costs much less than dealing with the same problem after months of neglect.

Beyond the financial cost, ignoring the warning signs of an ageing system can mean dealing with several failures at once instead of planning and budgeting for the work. There's also a practical insurance consideration: insurers can contest claims where the damage can be shown to result from a known, gradually-developing problem that wasn't addressed in a reasonable timeframe. Documented early action by an electrician helps protect both the home and your claim.

How an electrician usually fixes this

The right approach to power surges and outages after storms is methodical, not rushed. A good assessment looks at the condition of the whole system, not just the failed part, so any replacement is scoped properly. Here is what an electrician will usually work through on a typical attendance:

1. Safety Assessment. A licensed electrician inspects the fault or project area, checking switchboard condition, circuit loads, and any safety hazards before work begins.
2. Scope & Quote. A written quote is provided. For safety compliance work, the electrician explains any mandatory requirements under the Australian Wiring Rules (AS/NZS 3000).
3. Licensed Installation. All work is completed by a licensed electrician using compliant materials. No unlicensed electrical work is legal in NSW.
4. Certificate of Compliance. Upon completion, a Certificate of Compliance for Electrical Work (CCEW) is issued — required by insurers and essential for home sales.

The advantage of working through power surges and outages after storms this way is that nothing gets skipped. Every step produces something the homeowner keeps — a diagnosis, a quote and, where required, a compliance certificate — and each one is useful if NSW Fair Trading, your insurer, or a future buyer ever asks about the work.

How jobs are usually priced

What you pay an electrician for power surges and outages after storms comes down to the scope of the work, access, the materials specified, and how urgent the job is. Difficult access, non-standard materials or hidden damage will push the price up, so ask each electrician to itemise labour and materials in a written quote.

Minor repair

Call-out + parts

Moderate work

Fixed quote

Major project

Inspect, then quote

Price depends on the cable run from the switchboard, access through walls and ceilings, the switchboard's condition and capacity, and the fittings chosen. Ask for the call-out fee and hourly rate before work starts, and for a CCEW when the work is done.

A written quote with a clear scope of works is your protection here. Don't accept a verbal price for power surges and outages after storms — if there's a disagreement later, the written scope is what everyone will refer back to.

Licences and rules in NSW

Electrical work in NSW requires a licensed electrical contractor and/or licensed electrician. Unlicensed electrical work is illegal and dangerous. Always verify the licence at NSW Fair Trading before engaging an electrician.

These government websites explain the rules and let you check a licence:

• NSW Fair Trading – Electrical Contractor Licence
  Check your electrician holds a current NSW electrical contractor licence before they start work.
• SafeWork NSW – Electrical Safety
  NSW Government electrical safety regulations and requirements for residential and commercial work.
• Endeavour Energy – Local Electricity Network
  Endeavour Energy runs the electricity network in Blacktown City — contact it about power outages and network connection queries.
• Energy NSW – Home Energy Efficiency
  NSW Government rebates and schemes for energy efficiency upgrades including solar and EV chargers.

Hiring an unlicensed tradie for power surges and outages after storms when the job needs a licence might look cheaper on the day, but it can cost far more later. Insurers may not cover resulting damage, the work may have to be redone, and getting defects fixed is harder. If you're unsure whether the work needs a licence, ask the tradie and check with NSW Fair Trading.

Common questions

• How do I protect my appliances from power surges in Western Sydney?

  Power surge protection works at two levels. Whole-house surge protection installed at the switchboard by a licensed electrician protects all circuits at once. Individual plug-in surge protectors at point-of-use are a lower-cost supplementary measure for high-value equipment like televisions and computers. Equipment like refrigerators, air conditioners, and washing machines with electronic controls can also be damaged by surges, so ask the electrician what level of protection suits your home and appliances.

• Will my insurance cover surge damage to appliances in Blacktown?

  Many home and contents insurance policies cover sudden electrical damage from power surges, but cover varies. Usually the damage must be sudden and unexpected (not gradual deterioration), and you may need a report from a licensed electrician or repairer documenting the cause. Some policies have specific exclusions or limits on electrical damage — review your PDS carefully. If the surge was caused by a fault on the electricity network, you may also be able to lodge a claim with the network operator (Endeavour Energy in Blacktown City), though whether it pays depends on the cause.

• What should I do after a storm causes a power outage in my suburb?

  Report the outage to your electricity network's faults line (it's on your power bill) — this triggers restoration work. Do not touch any downed powerlines and call 000 if powerlines are on the ground. When power is restored, check all safety switches and circuit breakers in your switchboard — a surge can trip them. Have a licensed electrician inspect any appliances that were connected during a lightning strike, particularly if they show signs of malfunction.
