Yes. Yiannis integrates battery storage with existing solar and your switchboard, safely and to standard.

There is no official ranking to point at, so here is what is checkable: licence REC 28523 on the EnergySafe Victoria register, ARCtick certification for refrigerant work, 4.9 stars across 53 Google reviews, and the same pair of hands from the quote to the Certificate of Electrical Safety.

It does. Sunbury is roughly 20 km from the Craigieburn base and part of the normal week. If the timing does not work, Yiannis says so rather than leaving you waiting.

There is no fixed arrival time on offer. A solo sparky who guarantees one is guessing. What you get instead is emergencies prioritised across Sunbury and Melbourne North-West, and a straight answer on the phone about when he can be there. 0434 254 474.

You will know before he starts, not after. A remote figure either pads the job for safety or undershoots and surprises you on the day, and neither is fair. Yiannis assesses it in Sunbury, tells you what he found, and quotes it free.

Yes, and the licence is worth verifying: REC 28523 with EnergySafe Victoria, plus ARCtick certification for refrigerant work. Fully insured. In Victoria, fixed electrical work carried out by anyone unlicensed is not merely risky — it is unlawful.

Yes. For the fixed electrical work that requires one, Thunderman lodges a Certificate of Electrical Safety with EnergySafe Victoria. It is not paperwork for its own sake: it is what proves to you, to your insurer and to the regulator that the work was done to standard.
