Meet the man behind the bolt.

Where it started.

Yiannis Knodarites grew up in Cyprus, taking things apart to see how they worked. The first thing he properly pulled to pieces was a remote-controlled car — he wanted to know how the wheels were getting their power, and how the lights came on. After that came home-made lighting rigs and little motor-driven fans, built for the fun of it. In the school holidays he worked on construction sites, picking up a bit of everything from the tradesmen around him — foundations, carpentry, plumbing, electrical. By then he already knew which trade was his, so he apprenticed in two at once: electrical by day, plumbing by night, qualifying in both. When solar panels first started appearing on the market, he studied those too.

In 2010, at twenty-three, he came to Australia for a holiday and never went home. To work here properly he started the four-year electrical apprenticeship again from scratch — re-licensing to Australian standards rather than trading on a qualification earned overseas. By his fifth year he'd earned his contractor's licence and started Thunderman as a registered electrical contractor. In the years since he's added an air-conditioning licence, become police-certified for alarm and camera installations, and moved with the work into solar and home batteries. The thread running through all of it is the same one from that Cyprus workshop: he wants to understand the whole system — and he wants his name on it.

You'll always get Yiannis.

Big firms send whoever's free. Thunderman sends the owner. When you book Thunderman, the person who quotes your job is the person who does it — and the person who stands behind it afterwards. The phone is Yiannis's mobile, not a switchboard. The van that pulls up is his, with his name and licence number on the side. The Certificate of Electrical Safety that goes on file at EnergySafe Victoria carries his signature. That's accountability you can't fake, and it's why so many Thunderman clients are repeat clients — the home he rewired years ago rings again for the kids' bedroom power points; the shopfront he fitted out calls back when a new tenant takes the lease. There's no account-handoff because there's no account team. There's just a bloke, his work, and a phone that rings.

Good work is quiet work.

Yiannis' philosophy is simple: when electrical work is done properly, you forget it's there. No buzzing switches. No mystery breaker that keeps tripping every spring. No callback because someone left a junction loose behind a plaster wall. He explains what he's doing and why — what the existing wiring will and won't carry, why a Type B RCD costs more than a Type A, why a 4.6 kW reverse-cycle unit is the wrong call for a Brunswick weatherboard with a 3 m ceiling — and then he does the job once, properly, leaves the site cleaner than he found it, and writes you the Certificate. The art, as the homepage puts it, is in the quiet. A power point that does its job for thirty years and never asks for anything is the highest praise a sparky can earn.

A mark on the community.

One-bloke trades live or die on word of mouth, and Yiannis has built something he's genuinely proud of: a 4.9-star average across 53 verified Google reviews — the score that survives every difficult day, every awkward callback, every honest "we shouldn't do that, mate, the switchboard won't carry it" conversation. He encourages every customer to leave an honest opinion of the work and the business, good or otherwise — a review you've earned counts for more than one you've chased. They accumulate quietly because the work does. Many of the names on the reviews page are repeat clients of many years, and several came from a recommendation made across a fence.

Thunderman doesn't sponsor the Craigieburn footy team or buy billboards on the Hume. The community presence is simpler: when something on the street goes dark on a Sunday night, the neighbours know whose number to dial. That is the only Melbourne electrician Yiannis has ever wanted to be.

From Yiannis.

"I started Thunderman because I wanted my name on the work — every job, start to finish. That's still the rule. I respect every customer, and I want the work to be the best value for what you put into it, whether that's your electrical, your aircon or your solar. I'd rather build a relationship than chase a sale, because I want Thunderman to be the number you keep. If you call it, you'll get me. If something needs explaining, I'll explain it. If a problem turns up next month, I'll be the one fixing it. That's the whole pitch."
