What Affects the Cost
New install vs replacement. Replacing an existing fitting where wiring already runs costs $50–$80 per point. Running new cable from the switchboard to a location with no existing wiring costs $100–$200+ per point.
Ceiling construction. Plasterboard with roof access is ideal. Lath-and-plaster ceilings, common in pre-war terraces across the Inner West and Surry Hills, crumble around cut-outs and often need
plastering repairs. Budget an extra $80–$150 per affected area on top of the electrical quote.
Apartment vs house. In apartments, cable routes are limited by concrete slabs above and strata common walls. Houses with roof access are far simpler.
Dimmer switches. Adding a Clipsal Iconic LED dimmer ($30–$60 per mechanism plus installation) costs extra. LED-compatible dimmers are non-negotiable. Cheap trailing-edge dimmers designed for halogen cause flickering and buzzing with LED loads.
Number of points. Bulk installs of 10+ downlights in one visit bring the per-point cost down to $50–$70. A single fitting call-out runs $100–$150 effective cost because the call-out fee is spread across one point.
Old halogen transformers. Converting MR16 halogen downlights to LED often means replacing the 12V transformer too ($20–$40 per point in materials). Old transformers cause flickering, buzzing, or failure to start with LED drivers.
Colour temperature. Not a cost driver directly, but getting it wrong means paying twice. 2700K (warm white) for living rooms and bedrooms, 4000K (cool white) for kitchens and bathrooms. Confirm samples before ordering in bulk.
A simple LED downlight replacement in a modern western suburbs home with plasterboard ceilings and roof cavity access sits toward $80. A new lighting installation in an Inner West terrace with lath-and-plaster ceilings, no roof access, plastering repairs, and halogen transformer replacements pushes toward $300.
Sydney-Specific Considerations
Sydney's housing stock varies dramatically by area, and it directly affects what you will pay for lighting work.
Inner West terraces. Paddington, Surry Hills, Newtown, Balmain, Leichhardt. These homes, many built between the 1870s and 1920s, have lath-and-plaster ceilings with minimal or no roof cavity access. Cutting downlight holes through fragile horsehair plaster often causes cracking that radiates well beyond the cut-out, requiring a plasterer to repair the ceiling after the electrician finishes. Heritage-listed properties in Paddington and Balmain may have restrictions on visible modifications to decorative ceiling roses and cornices. For these homes, pendant fittings hung from existing ceiling points are often a simpler alternative to recessed downlights. IC-4 rated fittings are still needed wherever insulation exists, though many pre-war terraces have minimal ceiling insulation.
Apartments from Bondi to Parramatta. Apartment lighting work in NSW typically requires strata approval before any electrical modifications begin. Concrete slab ceilings above make recessed downlights impossible in most cases. Surface-mount fittings, track lighting, or pendant lights from existing junction boxes are the practical alternatives. Your body corporate by-laws will specify what modifications require approval and whether work is restricted to business hours. Ausgrid manages the distribution network across eastern Sydney, the Inner West, North Shore, and Northern Beaches. If your switchboard needs additional circuits before new lighting can be added, that is the distributor your electrician will coordinate with.
Western Sydney and growth corridors. Kellyville, Oran Park, Marsden Park, Box Hill. Post-2000 homes with plasterboard ceilings, accessible roof cavities, and standardised open-plan layouts. This is where lighting jobs are most predictable and sit closest to the lower end of the range. A full-home halogen-to-LED conversion (15–20 downlights) is one of the most common jobs in these suburbs, and bulk pricing brings the per-point cost down significantly. Western Sydney falls under Endeavour Energy rather than Ausgrid.
North Shore and Northern Beaches. Mosman, Chatswood, Manly. Larger homes with open-plan renovations driving demand for 12–20+ downlights across kitchen, dining, and living zones. Multiple dimmer zones (separate kitchen task lighting from dining ambience) are popular. Homes from the 1960s–70s may have degraded TPS wiring that needs attention during a lighting upgrade.
Hiring a Licensed Electrician in NSW
In NSW, all electrical work must be done by a licensed electrician. Verify their licence on the NSW Fair Trading website by searching their name or licence number.
After the work is finished, your electrician must issue a CCEW (Certificate of Compliance Electrical Work). This is your proof the work meets AS/NZS 3000:2018. Ask for it before final payment. From July 2026, all CCEWs must be submitted digitally via the BCNSW eCert portal. Handwritten forms will no longer be accepted, and failure to provide a CCEW carries a $1,000 on-the-spot fine.
A good electrician will:
Confirm IC-4 rating requirements after inspecting your ceiling insulation
Check dimmer-to-LED compatibility before ordering fittings
Advise on colour temperature and help you avoid ordering the wrong Kelvin rating in bulk
Issue the CCEW on or near the day of completion
Worth checking:
That a CCEW will be issued on or near completion day
That the ceiling cavity is inspected before quoting (not quoted from photos alone)
That IC-4 rated housings are specified wherever insulation contacts the fittings
How We Calculate
Estimates are based on current licensed Electrician rates in NSW, adjusted for Sydney's labour market and typical property types. All prices include GST. We factor in standard materials (IC-4 rated LED downlights, cable, dimmer switches where specified), call-out fees, and typical job complexity. Premium fittings, switchboard upgrades, or plastering repairs are excluded and would be quoted separately by your Electrician.
