How Much Does Outdoor Lighting Installation Cost in Perth? (2026 Prices)
Quick answer: in Perth in 2026, replacing an existing outdoor wall light costs $160 to $250 in labour, a new outdoor light on new wiring $300 to $450, a sensor floodlight over the driveway or side gate $300 to $500 supplied and installed, and a low-voltage garden lighting system of six to eight lights $1,200 to $2,500. Fittings are extra where you supply them; we can supply everything from a $60 bunker light to coastal-rated brass.

Outdoor lighting in Perth does three jobs: security (the sensor floodlight that stops the side gate being a blind spot), safety (steps, paths and the alfresco after dark) and the good stuff — a garden that looks as good at 9pm in February as it does at noon. The cost depends far less on the fitting than on the wiring: reusing an existing point is a quick job; running new cable to the front gate or through the garden isn't.
This guide gives you the 2026 prices for each kind of outdoor lighting job in Perth, what's done on the day, how to choose fittings that survive salt air and reticulation, and the rules that apply.

Outdoor lighting costs in Perth in 2026
| Job | Typical Perth price (2026) | Notes |
|---|---|---|
| Replace an outdoor wall or eave light (wiring in place) | $160 – $250 | Labour and the swap; fitting extra if we supply |
| New outdoor light on new wiring | $300 – $450 | Cable from the nearest lighting circuit, switch or sensor |
| Sensor floodlight, supplied and installed | $300 – $500 | LED flood with PIR sensor over the driveway, side gate or back yard |
| Alfresco lighting (4–6 downlights or a pendant, one switch) | $600 – $1,100 | IP-rated fittings, often paired with a fan |
| Low-voltage garden lighting, transformer and 6–8 lights | $1,200 – $2,500 | Path lights, spike spots on trees, step lights; fittings drive the price |
| Festoon lights over a deck or pergola | $400 – $900 | Outdoor-rated string, catenary wire, a weatherproof point and switch |
| Add: underground run to a gate, letterbox or shed | +$400 – $1,200 | Trench, orange conduit, weatherproof junctions |
| Add: dusk-to-dawn sensor, timer or smart switch | +$80 – $300 | Set-and-forget control is the difference between lights you use and lights you don't |
Fittings range from $40 for a basic bunker light to $300+ for a coastal-rated brass or 316 stainless fitting, and garden lights from $30 to $150 each. Labour is where the money goes on new positions — reaching the point, running cable in the roof or underground, and doing it so it's still working in ten years.
What's actually done on the day
- Plan the positions. Where the light needs to fall (the path, the door, the gate — not the neighbour's bedroom), where the cable can run, and where the switch or sensor goes.
- Isolate the circuit and confirm RCD protection — outdoor circuits must have it.
- Run the wiring. Through the eaves or roof space to wall and eave lights; in conduit on the wall where it's exposed; in a trench with orange conduit for anything underground, at the depth the Wiring Rules require.
- Mount the fittings with weatherproof bases and sealed entries, sensors aimed and their sensitivity set so the cat doesn't trigger them all night.
- Garden systems. A transformer at a weatherproof point, low-voltage cable through the beds, lights positioned and adjusted after dark.
- Test and certify. Polarity, earth, RCD trip, sensors and timers checked; your Electrical Safety Certificate follows.
A replacement takes under an hour; a sensor flood on new wiring one to two hours; a garden system most of a day.

Choosing outdoor lights for Perth
- IP rating. IP44 for under eaves and covered alfrescos; IP65 for anything the rain or the reticulation reaches; IP67 or 68 for in-ground and pond lights.
- Coastal suburbs. Salt air eats standard aluminium and mild-steel fittings in a couple of summers in Scarborough, Fremantle, Rockingham and Secret Harbour. Choose 316 stainless, solid brass, copper or marine-grade powder coat.
- Sensors. A PIR floodlight for security; a dusk-to-dawn sensor for entry lights; a timer or smart switch for the garden.
- Colour. Warm white (2700–3000 K) for entertaining areas and gardens; cooler (4000 K) for security floods.
- Low-voltage vs 240 V. Low-voltage garden systems are cheaper to run cable for and easy to add to; 240 V fittings suit walls, eaves and floods.
- Bugs. Amber or warm LEDs attract fewer insects than cool white — worth knowing on a Perth summer night.
The WA rules that apply
- Licensed contractor only. Any 240 V outdoor light, sensor or switch is electrical work for a licensed electrical contractor (our licence is EC15449). Low-voltage garden lights plugged into an existing outdoor point are the one thing you can DIY.
- RCD protection on outdoor circuits under AS/NZS 3000:2018.
- Underground cable must be in conduit at the required depth, with orange marker tape where required — the rules exist because people dig.
- Pools and spas. Strict zone rules for fittings and cables near water; only suitably rated low-voltage or specifically certified fittings inside the zones.
- Neighbours. Councils can act on light spill; aim floods down and into your own yard.
- Electrical Safety Certificate for the work, within 28 days.
What pushes the price up (or down)
- Existing wiring. A point already on the wall is the cheap job.
- Cable route. Eaves and roof space are quick; solid walls, paving and lawns cost time and trenching.
- Number of lights. The first light carries the visit; the rest are much cheaper.
- Fittings. Basic to coastal-grade is a tenfold spread on the fitting alone.
- Control. Sensors, timers and smart switches add a little; the right control is what makes the lights useful.
- Distance from the switchboard. A new circuit for a big garden system or a shed adds a run to the board.

Ways to keep the cost down
- Reuse existing points and upgrade the fittings and control instead of rewiring.
- Do the whole outside at once — front, side gate, alfresco and garden in one visit.
- Choose low-voltage for the garden and 240 V only where it's needed.
- Plan trenches with other work — reticulation, paving or a new fence is the time to run conduit.
- Buy coastal-rated fittings the first time if you're near the coast; replacing corroded ones is the expensive way to learn.
Frequently asked questions
How much does it cost to install a sensor light in Perth?
About $300–$500 supplied and installed for an LED floodlight with a motion sensor on new wiring, or $160–$250 to replace an existing sensor light like for like.
Can I install outdoor lights myself?
Only plug-in low-voltage garden kits. Any 240 V fitting, switch, sensor or new wiring is licensed electrical work in WA, and outdoor circuits have extra requirements for RCD protection, IP ratings and underground cable.
How much does garden lighting cost?
A low-voltage system with a transformer and six to eight path and spike lights is typically $1,200–$2,500 installed in Perth, depending mostly on the fittings. Adding lights to an existing system is cheap.
What IP rating do outdoor lights need?
IP44 under eaves and in covered alfrescos, IP65 anywhere rain or reticulation reaches, IP67–68 for in-ground and pond lights. Near the coast, the material matters as much as the rating — 316 stainless or brass.
How long does outdoor lighting installation take?
Under an hour for a replacement, one to two hours for a new light or sensor flood on new wiring, and most of a day for a garden system or anything with trenching.
Can outdoor lights be put on a timer or app?
Yes. A dusk-to-dawn sensor or a timer suits entry lights; a smart switch or a Wi-Fi transformer suits gardens and festoons. It adds $80–$300 and it's what makes the lights get used.
Do outdoor lights need a safety switch?
Yes. Outdoor circuits must be RCD-protected. If your switchboard doesn't have RCDs on the lighting, we add one as part of the job.
