What does garden lighting cost?

Current retail examples checked on 6 November 2026 range from A$30 including GST for four standalone solar disc lights to A$99 including GST for a three-light 12V plug-in spotlight kit. A ten-light recessed 12V deck kit is listed at A$89.99. These are product examples from one Australian retailer, not installed prices, national averages or a forecast for your garden.

A complete quote can be much larger than the light-box price because the result may also need layout and aiming, a suitable transformer or driver, cable and connectors, trenching or concealed deck access, drilling, weather-protected power, controls, licensed fixed electrical work, night commissioning and reinstatement. Compare the same finished outcome, not the cheapest fixture count.

Choose the system by the job it must do

Use standalone solar lights where a simple removable marker or decorative effect is enough and the solar panel can receive suitable daylight. A plug-in manufacturer-approved 12V kit can suit a defined path, planting bed or deck when its transformer, cable length, fittings and connection system match the layout. Fixed lighting may be appropriate where the project needs permanent wall, step, switching or power arrangements, but electrical installation work has a different trade and compliance boundary.

Write the purpose beside every proposed light: guide movement, reveal a step, light a task area, wash planting, highlight one tree or support security. One fixture should not be assumed to do all of these jobs. Product wattage, lumens, beam, colour and ingress rating describe parts of a product; they do not by themselves prove that the quantity, position or installation is suitable for a particular site.

Set out the night result before pricing fixtures

Mark the route people actually use from gate to door, entertaining area and bins. Identify changes of level, step nosings, deck edges and gates, then mark features worth lighting and areas that should stay dark. Include neighbouring windows and road users in the aiming check. More fittings can increase glare, visual clutter, cable length and maintenance without improving the route.

Ask each business to price from the same marked photo or sketch. Record the proposed fixture type, location, mounting height, direction and control zone. A night test or commissioning visit should aim and adjust the lights after planting, mulch and built work are in place. An AI concept can help discuss mood and placement, but it cannot calculate photometric performance, electrical capacity, cable routes or construction details.

Price the transformer, cable and route as one system

For a plug-in 12V system, check what the kit actually includes. An add-on spotlight may require a transformer and cable sold separately, while a starter kit may include both but only for its stated load and reach. The quote should identify the transformer or driver, connected wattage, spare capacity, compatible fittings, cable type and length, connectors and accessible mounting location. Do not assume products from different systems can be mixed safely or supported by the manufacturer.

The physical cable route often controls labour. Ask whether cable is surface-routed, concealed under a deck, installed in a prepared garden bed or coordinated before paving and planting close the area. Price trenching, penetrations, protection, service checks, spoil and reinstatement explicitly. Keep connectors and equipment accessible where the product instructions require maintenance; do not bury an undefined connection merely to make the quote look complete.

Compare solar, plug-in 12V and fixed electrical scope

Solar avoids a cable route but still needs suitable placement, stable mounting, enough daylight for the product and a plan for battery or fixture replacement. Its output and run time can change with product specification, charging conditions, season, shade and ageing. Compare the stated product performance with the task rather than assuming every solar path light is suitable as safety or security lighting.

A plug-in 12V kit has a mains-powered transformer even though the garden-side fittings operate at extra-low voltage. The supplied transformer, plug, outlet location, cable and connectors remain part of the system. Fixed or altered wiring, a new power point or non-plug-in lighting must be separated from the landscaping allowance and assigned to the appropriately licensed electrical contractor for the jurisdiction.

Keep fixed electrical work inside its licence boundary

In Victoria, Energy Safe Victoria says electrical installation work must be performed through a registered electrical contractor and a Certificate of Electrical Safety must be provided after the work. Its examples of non-prescribed work include lighting points and non-plug-in electrical equipment. Other states and territories have their own regulators and requirements, so check the current rule where the property is located.

A product described as DIY does not authorise a homeowner or landscaper to install or alter fixed wiring. Confirm who supplies any new outlet, circuit, switch, fixed fitting or connection; what electrical work is excluded from the landscaping quote; and how the electrical contractor's work, testing and certificate are handed over. Do not conceal electrical scope inside a general 'install lights' line item.

Compare quotes by the finished route and handover

Ask for itemised fixtures, transformer or driver, cable, connectors, controls, mounting, trenching or drilling, electrical work, testing, aiming, cleanup and reinstatement. Check quantities and model numbers against the shared layout. Confirm whether delivery, GST, warranties, night commissioning and future access to equipment are included. A cheaper quote may simply omit the route, power or restoration priced by another business.

business.gov.au recommends a written quote with a clear work description, itemised and total costs, GST where applicable, variations, payment terms, start and finish dates, expiry and acceptance. Add lighting-specific exclusions such as a new power point, deck-board replacement, unexpected buried obstructions, tree-root excavation or changes after paving. Require written approval before changed scope or products are installed.

Use RealScape to brief the same lighting outcome

RealScape can create an AI garden concept from a permitted site photo to explore the visual direction, or you can request landscaping quotes without generating an image. Add the marked lighting purpose, route, fixture preferences, control requirements, existing power information and access constraints to the editable project brief so businesses can respond to the same starting point.

The concept is not an electrical design, measured lighting plan, permit, compliance certificate or construction estimate. RealScape does not calculate fixture quantities, transformer capacity, voltage drop, trench depth or installation price. Final products, cable routes, licensed work and costs must be assessed and quoted by the relevant professionals for the property.

Garden lighting quote checklist

  • The same site sketch or marked photo issued to every business, showing paths, steps, entries, deck edges, planting, feature trees, entertaining areas, neighbouring windows and areas that should remain dark
  • The purpose of each light - safe movement, task lighting, ambience, feature lighting or security - plus the target area, aiming direction, colour temperature and switching behaviour
  • Exact fixture schedule with brand, model, quantity, finish, output where available, beam or spread, mounting method, stated IP rating, warranty and whether lamps, drivers or batteries are replaceable
  • System type for each zone: standalone solar, manufacturer-approved plug-in extra-low-voltage kit, or fixed electrical installation, without treating those systems as interchangeable
  • Transformer or driver model, total connected load, spare capacity, compatible fittings, cable type and length, connectors, voltage-drop assessment where relevant and an accessible location for maintenance
  • Cable routes, trench or conduit scope, deck or wall penetrations, underground-service checks, protection from tools and traffic, drainage around equipment, spoil handling and surface reinstatement
  • Existing power-point location and weather protection, any new or altered fixed wiring, the registered electrical contractor responsible, and the Certificate of Electrical Safety required for Victorian electrical installation work
  • Controls and commissioning: manual switch, timer, dusk sensor, motion sensor or smart control; zones, schedules, aiming, glare check, night test and handover instructions
  • Responsibility for coordinating lighting before paving, decking, irrigation and planting close access to cable routes, plus an as-installed route or fixture record for future work
  • Itemised supply and labour, delivery, GST, exclusions, allowances, start and completion assumptions, quote expiry, product and workmanship warranties and the written variation process

Sources and date checked

For Australian homeowners, start with a real backyard photo and use an AI concept to explore a practical dream-garden direction. The visual can make style, layout, planting, and material preferences easier to explain before requesting quotes.

Turn the preferred concept into a clearer project brief, find suitable landscapers, and compare scope, inclusions, exclusions, and options against the same visual direction. Homeowner quote requests are free.

The concept is an early planning aid rather than a measured plan or promise of the finished result. Confirm drainage, levels, access, services, permits, engineering, materials, and construction details with the appropriate professionals.
