Electrician in Mosman
Switchboards, EV chargers and lighting for Mosman's harbourside homes and apartments — from Federation houses under heritage overlay to newer builds by the water.
What we actually see in Mosman
Mosman is close to an even split between houses and apartments — around 52% of dwellings are units, which is unusually high for a suburb this leafy. The houses skew Federation and inter-war, a lot of them inside Mosman Council's heritage conservation areas, which changes how we run new cable and where a switchboard can go — concealed and discreet, not just wherever's easiest.
Being wrapped by water on three sides — Mosman Bay, Sirius Cove, Balmoral — means salt-laden air gets into everything. Switchboards, outdoor power points and garden lighting corrode and pit noticeably faster here than a few kilometres inland, and it's usually the reason an otherwise fine-looking board fails early.
Mosman also ranks #2 nationally on the ABS's socio-economic index (behind only Woollahra) and has one of the highest rates of EV ownership in NSW — 4.75% of registered vehicles in the LGA are now battery-electric. Between that and the apartment share, two questions come up constantly: whether the switchboard has capacity for a charger, and whether a fault is the owner's problem or the owners corporation's.

Mosman questions
We're in a heritage conservation area in Mosman — can you still upgrade our switchboard?
Yes. Like-for-like electrical work inside the house doesn't usually need council approval, and we route new cable and position boards to stay concealed rather than bolted to a front-facing wall. If a job would change the external appearance of a heritage item, we'll flag that before we start so you can check with Mosman Council.
We're in a Mosman apartment — who pays if the switchboard on our floor fails, us or strata?
As a rule of thumb, the sub-board and everything past it inside your lot is your responsibility; the meter room and the mains feeding it are the owners corporation's. Disputes happen most often over meter boards on common property. We can inspect the fault and tell you which side of that line it sits on before you call strata.
Can our owners corporation refuse an EV charger in Mosman?
It's harder than it used to be. EV charging is now classified as sustainability infrastructure under NSW strata law, so it only needs a simple-majority vote and aesthetic-only refusals have been prohibited since 1 July 2025. The Right to Charge reforms currently before NSW Parliament are expected to make this simpler still. Strata EV installs typically run $2,500–$6,000, a standard single-phase home charger $1,200–$2,500 — a guide, not a quote.
Our switchboard near the water keeps corroding — why?
Salt-laden air off Mosman Bay and Balmoral accelerates corrosion on terminals, enclosures and anything metal in an outdoor switchboard or garden lighting circuit. If your board is more than 10–15 years old and near the harbour, it's worth a proper look rather than waiting for it to fail.
What customers say
Excellent value and service, including follow-up.
Had a great experience with Jason — top guy at what he does. I recommend him.
The downlights connected to our C-Bus system were flickering. Jason explained the issue in detail, provided a solution and the lights are now working perfectly. Highly recommend — a professional and honest approach delivering excellent work.
