What's Included in the Price
- Site assessment. Your electrician inspects the route from the nearest power source to where you need the outlet, checking wall construction, underground obstacles, and switchboard capacity. For longer runs they will also calculate voltage drop to determine cable sizing.
- Cable run. Along walls in UV-stabilised surface-mount conduit, underground in orange heavy-duty conduit, or a combination. All work must comply with the AS/NZS 3000 Wiring Rules, including minimum burial depths of 300mm in conduit and warning tape above the cable path.
- Weatherproof fittings. Standard Clipsal Weathershield or Iconic Outdoor GPOs (IP53–IP54, $20–$35 per point) for sheltered spots under eaves or covered patios. Clipsal IP56 switches for partially exposed areas. IP66 industrial-grade or marine-grade enclosures ($80–$250) for fully exposed and coastal locations.
- Circuit protection. A dedicated circuit breaker and RCD at the switchboard. AS/NZS 3000 requires RCD protection on every outdoor circuit to detect earth leakage faults.
- Trenching. For underground cable runs. Includes digging to compliant depth, laying conduit, backfilling, compacting, and installing route marker tape.
What Affects the Cost
- Distance from the switchboard. The dominant factor. A 3-metre run through one wall to a back patio is a half-day job. A 25-metre underground run to a back shed is a full-day-plus project with trenching, heavier gauge cable, and potentially a sub-board.
- Wall construction. Drilling through brick, sandstone, or concrete takes significantly longer than timber framing. Sydney's mix of sandstone terraces, brick veneer, and rendered concrete means wall penetration time varies widely by suburb.
- Underground vs surface. Underground runs look cleaner but cost more due to trenching, conduit, and backfill. Surface-mount conduit along walls and fences is quicker and cheaper. Cable sizing must comply with AS/NZS 3008 voltage drop limits, requiring heavier gauge cable (4mm² or 6mm²) on runs over 20 metres.
- Switchboard capacity. If the board is full, adding a circuit means upgrading the switchboard first, which is a separate cost.
- Weatherproofing level. Coastal and harbour-side properties need marine-grade stainless steel enclosures with IP66+ ratings. These cost 3–5 times more than standard plastic weatherproof fittings. In suburbs like Bondi, Coogee, and Manly, standard fittings corrode within months.
- Pool and spa zones. AS/NZS 3000 Section 6 defines a 2-metre exclusion zone from the water's edge where no electrical infrastructure is permitted. Equipment beyond this zone needs equipotential bonding to the pool structure. Many Sydney homes with pools need dedicated circuits for pump, chlorinator, and heating.
A weatherproof Clipsal GPO mounted on a brick external wall near an existing indoor circuit, with a short cable run through one wall, sits toward $1,500. An underground cable run to a detached granny flat, with trenching through an established garden, a separate sub-board, marine-grade fittings for a coastal property, and RCD-protected circuits for a pool pump, pushes toward $4,500.
Sydney-Specific Considerations
Sydney's compact urban blocks and diverse housing stock make outdoor power installations more varied than in most other cities.
Compact inner-city blocks. Newtown, Marrickville, Leichhardt, Petersham. Small backyards with limited access paths mean cable routing is constrained. Getting underground cable past existing garden beds, paths, and fences often requires creative conduit runs along boundary walls rather than direct trenching. Many terraces in these suburbs have sandstone or double-brick walls that take considerably longer to drill than standard brick veneer. A good electrician will scope the cable route with you before quoting so there are no surprises once work starts. Ausgrid manages the distribution network across most of Sydney, so if your switchboard needs attention before new circuits can be added, your electrician coordinates with them.
Granny flats and studios. Sydney's ADU (secondary dwelling) boom drives high demand for running dedicated power to detached backyard buildings. These are among the most expensive outdoor power jobs: long cable runs (often 15–30 metres underground), separate sub-boards with their own RCD protection, and sometimes council DA requirements. If the granny flat qualifies as a secondary dwelling, it may need separate metering. Coordinate with your builder early, as laying conduit before landscaping and paths are finished is far cheaper than cutting through them later.
Harbour and coastal properties. Mosman, Manly, Bondi, Coogee, Cronulla, Bronte. Salt air corrodes standard plastic and galvanised fittings rapidly. Marine-grade stainless steel enclosures and IP66-rated outlets are not optional in these locations. Budget 20–30% above standard for materials. UV degradation is also a factor on north-facing walls where conduit and fittings are in direct sun for most of the day. Specify UV-stabilised conduit from the start.
Pool and spa surrounds. Sydney's pool ownership rate is high, particularly in the eastern suburbs, northern beaches, and Hills District. Strict electrical exclusion zones under AS/NZS 3000 Section 6 apply around all pools and spas: Zone 1 extends 2 metres from the water's edge, and no electrical equipment is permitted within it unless protected by a compliant 1.8-metre splash barrier. Pool pumps, chlorinators, and heating equipment all need dedicated circuits with RCD protection and equipotential bonding. A good electrician will walk the pool zone with you before quoting.
Hiring a Licensed Electrician in NSW
All outdoor electrical work in NSW must be done by a licensed electrician. Verify their licence on the NSW Fair Trading website by name or licence number.
After completing the work, your electrician must issue a CCEW (Certificate of Compliance Electrical Work). From July 2026, CCEWs must be submitted digitally via the BCNSW eCert portal. This certificate is your proof the installation meets AS/NZS 3000, and your home insurance may not cover faults on uncertified work.
A good electrician will:
- Explain the proposed cable route and circuit protection before starting
- Specify the IP rating of fittings for your location (sheltered, exposed, or coastal)
- Calculate voltage drop on longer runs and size cable accordingly
- Issue a CCEW on completion without being asked
Worth checking:
- That dedicated RCD protection is included for the outdoor circuit
- That outdoor-rated (IP56+) fittings are specified, not indoor-rated alternatives
- That the cable routing plan is explained before work begins
How We Calculate
Estimates are based on current licensed Electrician rates in NSW, adjusted for Sydney's labour market and material costs. All prices include GST. We factor in standard cable runs, weatherproof fittings, circuit protection, and typical job complexity. Switchboard upgrades, landscaping reinstatement, pool zone compliance, or granny flat sub-boards are excluded and would be quoted separately by your Electrician.
