With the new Metro line and the Western Sydney Airport corridor reshaping the area, St Marys is changing fast — but its power still flows through Endeavour Energy's network. High Demand Electrical carries the Level 2 accreditation to connect, upgrade and repair that supply, certified with a CCEW on every project.
St Marys is growing. So is demand.
St Marys pairs one of Western Sydney's oldest town centres with street after street of post-war housing, and both put steady work in front of a Level 2 electrician. Service connections from the 1950s and 60s weren't built for today's loads, while new development along the station precinct needs fresh connections done right the first time.
As an Accredited Service Provider, we work directly on the network side — consumer mains, points of attachment, metering — and certify everything to AS/NZS 3000 and the NSW Service and Installation Rules.


New connections for a suburb in transition
Duplexes, townhouses and small subdivisions are appearing across St Marys as older blocks are redeveloped. Each new lot needs its own compliant connection, and multi-dwelling sites need supply designed for the combined load. We manage applications, installation and energisation with Endeavour Energy from a single point of contact.
Keeping Queen Street businesses powered
The commercial strip through St Marys runs everything from long-standing family shops to new fit-outs, and undersized supply is a common headache when a tenancy changes hands. We assess what the premises actually draws, upgrade the service and switchgear to match, and schedule the changeover around your trading hours.

Is three-phase worth it here?
Workshops, home businesses and heavily air-conditioned houses around St Marys often outgrow a single-phase supply. Converting to three-phase spreads the load across three conductors, ends nuisance tripping and opens the door to serious machinery or fast EV charging. We'll tell you honestly whether your usage justifies it.
Temporary disconnections for building work
Re-cladding, raising a roofline or knocking out the wall that carries your point of attachment all require the supply to be safely disconnected first, then reconnected once the structure is done. Booking us before the builder starts keeps your St Marys renovation moving instead of stalling mid-job waiting on power.

A short call is all it takes to scope your job and lock in a time. Phone High Demand Electrical and put an accredited Level 2 team on your St Marys project.
