Sydney Storm Season Prep: The Electrical Jobs to Do Before Summer Hits

What electrical jobs should Sydney homeowners do before storm season? Before summer hits, check the assets storms attack first: trees near your service line, the condition of any private power pole, your switchboard and safety switches, and surge protection. Sydney's storm season peaks between November and March, and the quiet months of September and October are when this work is cheap, unhurried and easy to book.

⚡ Quick Answers: storm season prep

• When is Sydney's storm season? Thunderstorm activity peaks from late spring through summer, roughly November to March. Our storm season guide covers why summer is worst.
• What fails first in a storm? Overhead assets: service lines struck by branches, private poles that were already weak, and points of attachment loaded by wind. Water in switchboards follows close behind.
• Whose job is tree trimming near powerlines? It depends which wires and which network. Our guide to vegetation clearance responsibility breaks down the split.
• Is surge protection worth it? A whole house surge device at the switchboard is one of the cheapest ways to protect tens of thousands of dollars of appliances from lightning driven spikes.
• What about blackouts? Decide before the season whether you want backup power. A standby generator with an automatic transfer switch takes weeks to organise, not hours.

1. Look up: trees and your overhead service line

Walk outside and follow the wire from the street to your house. Anything growing into or over that line is a summer failure waiting for a windy afternoon. Trimming near powerlines is not a DIY job, and who is responsible depends on whether the vegetation threatens the network's mains or your private service line, and which distributor you are on. Ausgrid and Endeavour Energy run different programs, covered in our Ausgrid trimming guide and Endeavour vegetation rules guide.

If you are not sure whose wires you are looking at, check your network area in seconds with our postcode checker before you ring anyone.

2. Check your private power pole

If your property has its own pole, it is your asset and your responsibility. Spring is the time to look for lean, rust at the base of steel poles, soft or cracked timber, and fungus at the ground line. A pole that fails in a February southerly takes your power, and possibly your neighbour's fence, with it. Our guide to pole warning signs covers what to look for, and a pole inspection or replacement booked in spring beats an emergency job in the middle of a blackout.

3. Test your safety switches

Every safety switch has a test button for a reason. Press it: the switch should trip instantly, and everything on that circuit should go dark. Reset it and move to the next one. A switch that does not trip is not protecting anyone and needs an electrician. Homes built before the early 1990s may have circuits with no safety switch at all, which is worth fixing before the wet weather arrives, since moisture is exactly what these devices catch. If your switch already trips whenever it rains, that pattern has its own causes, covered in safety switch tripping after rain.

4. Give the switchboard and meter box a visual once over

Do not open anything. Just look. Rust streaks, cracked enclosures, perished door seals, gaps where cables enter and scorch marks are all signs the board will not keep the weather out come summer. Water in a switchboard is one of the most dangerous storm outcomes, as our wet switchboard guide explains, and an ageing board is better dealt with as a planned switchboard upgrade than an emergency replacement.

5. Sort surge protection before the lightning arrives

Lightning does not need to hit your house to destroy the electronics in it; a strike streets away can push a damaging spike down the network. Plug in powerboards only protect what is plugged into them. A whole house surge protection device installed at the switchboard protects everything behind it, and it is a small job when done during a planned visit. Our whole house surge protection guide covers the options.

6. Save the numbers and make a blackout plan

Put the emergency numbers in your phone now: Ausgrid 13 13 88, Endeavour Energy 131 003, and 000 for anything life threatening. Our emergency contacts guide lists the lot. Then think about what actually stops in a blackout at your place: fridge, freezer, garage door, medical equipment, work from home gear.

If losing power for a day or two is more than an inconvenience, spring is when to plan backup power. A standby generator paired with an automatic transfer switch restores essential circuits in under 75 seconds, but sizing, approvals and installation take time, so the decision belongs in October, not mid storm.

7. Know the difference between prep and the pre-storm check

This is the pre-season list: jobs done once, in the calm months. When a severe weather warning is actually issued, there is a separate 20 minute visual check worth doing on the day, covered in our pre-storm electrical checklist. And if damage does get through, who fixes what after a storm maps the responsibility split between you, the network and your insurer.

How High Demand Electrical helps

We do storm season preparation as a single visit across Sydney: electrical safety inspections covering the board, safety switches and visible wiring, private pole assessments, surge protection installation and quotes for any upgrade work found. As Level 2 ASPs we also handle the supply side, from overhead service line repairs to full power supply upgrades, and if summer still gets the better of your system, our 24/7 emergency make safe team attends storm damage year round.

Storm Season Prep FAQs (Sydney)

When should I book pre-season electrical work?

September and October. Electricians, networks and tree crews all get slammed once the first big storms land in late spring, and planned work booked early is cheaper than emergency work booked at midnight.

Can I trim a branch off my service line myself?

No. Even the insulated service line to your house can be deadly if the insulation is damaged, and work near network mains has strict clearance rules. Report network vegetation to your distributor and use qualified crews for anything near your private line.

Do I need a full inspection or can I just do the visual checks?

The visual checks above catch the obvious problems. A professional inspection adds the things you cannot see: insulation resistance, earthing, safety switch trip times and the condition inside the board. If the home is older or has never been checked, book the inspection.

What if I find something dangerous during my checks?

Stop, keep people away and call us on 0402 559 777. If a wire is down or sparking, stay 8 metres back and call your distributor first; our fallen power line guide covers the do and don't list.
