Holroyd's post-war brick and fibro homes were wired for a very different era, and many still run on the original service equipment. As an ASP Level 2 electrician accredited with Endeavour Energy, High Demand Electrical upgrades and repairs the supply side for homes across Holroyd, Merrylands and Greystanes.
Bringing Holroyd's older homes up to date
The cables and fittings between the power pole and your meter box belong to a category of work only a Level 2 Accredited Service Provider can touch. That covers the service line crossing your yard, the point of attachment on your fascia, the consumer mains and the metering itself. Around Holroyd, where much of the housing dates from the 1950s and 60s, these components are frequently at the end of their working life.
We renew them properly — compliant with AS/NZS 3000 and the NSW Service and Installation Rules, with a CCEW issued on completion.


Retiring the old fuse board
Ceramic fuses and cloth-insulated tails are still common behind Holroyd meter boxes. A modern switchboard with safety switches on every circuit is one of the most worthwhile upgrades an older home can get. We replace the board, renew the mains connection where needed and leave you with protection that actually trips before someone gets hurt.
Wiring risks in mid-century houses
Homes built in Holroyd's post-war expansion often hide deteriorated rubber or cotton-sheathed wiring in the roof space. Warning signs include flickering lights, warm switch plates and fuses that blow without obvious cause. We assess the installation honestly, prioritise what genuinely needs replacing and upgrade the supply side to support the rewiring work.

Fixing what the defect notice flagged
When Endeavour Energy inspects and finds unsafe service equipment — a sagging service line, corroded point of attachment or perished mains insulation — the owner receives a defect notice with a fixed timeframe. We handle these regularly across Holroyd and Merrylands: one visit to assess, a firm quote, the repair, and the notice closed out with the distributor.
Does your supply handle an EV charger?
A 7kW home charger can double a household's evening demand, and many Holroyd homes still run 100A single-phase supply or less. Before you order the charger, have us check your capacity. If it falls short, we upgrade the service — often to three-phase — so charging overnight never browns out the rest of the house.

Secure Your Grid Connection
From switchboards to full service upgrades, we quote clearly and turn up when we say we will. Call High Demand Electrical to book an assessment at your Holroyd home.
