Surge Protection Perth — Protect Your Whole Home
Storm season in Perth (November to April) takes out tens of thousands of dollars of household electronics every year. TVs, fridges, computers, modems, EV chargers, smart-home gear — all sensitive to voltage spikes that come down the grid when lightning hits a substation, or when a neighbour's transformer fails, or when Western Power switches a line. A whole-home surge protector at the switchboard catches the spike before it reaches your gear. Costs less than one TV. Lasts 5-10 years. Most Perth homes don't have one.

Frequently Asked Questions
Do plug-in surge protectors work?
They help for the gear they protect. A whole-home unit catches everything before it reaches the plug-in unit — they're complementary, not competing.
How long do surge protectors last?
Type 2 SPDs typically last 5-10 years, then they're spent (they sacrifice themselves to absorb spikes). Replacement is usually cheaper than the original install.
Will my insurer reduce my premium?
Some will. Worth asking — the compliance certificate is the document they want to see. Some policies specifically cover surge damage only if protection is installed.
