Why irrigation pricing varies
What determines the cost of an irrigation system?
Irrigation systems are not off-the-shelf products with fixed prices. Every garden is different, and the cost of a professionally designed system depends on a combination of site conditions, water supply and the scope of the installation. Below are the key factors that influence irrigation pricing.
Garden size
Larger areas require more pipework, more sprinklers or drip lines and often additional zones.
Number of zones
Dividing the garden into zones allows different watering schedules for lawns, borders and pots.
Water pressure
Available pressure determines how many sprinklers can run simultaneously on each zone.
Available flow
Flow rate (litres per minute) sets the capacity of each zone and whether a pump is needed.
Pipework
Underground MDPE pipework, solenoid valves and connection fittings scale with system size.
Sprinklers
Pop-up lawn sprinklers, shrub heads and impact sprinklers vary in coverage and cost.
Drip irrigation
Drip line and individual drippers deliver water precisely to borders, hedges and containers.
Controller
From simple timers to Wi-Fi weather-responsive controllers with remote access.
Pumps
Where pressure or flow is insufficient, a booster pump or pump set may be required.
Rainwater harvesting
Tanks, filters and pumps to capture and reuse rainwater add to the system scope.
Ground conditions
Soil type, existing planting and access affect installation time and method.
Existing landscaping
Established lawns and mature borders require careful, minimally invasive installation.
