Short Answer
Garden irrigation in Surrey typically starts from around £3,000 for a compact system covering borders and a small lawn, rising to £15,000–£40,000+ for large estate installations with multiple zones, borehole or rainwater supply and smart control. The price depends on the number of zones, garden size, water source and pressure, and whether a pump or rainwater harvesting is needed. A fixed quotation is only possible after a site survey.

What drives the price
The price is driven by:
- The number of zones
- The garden size
- The water source and pressure
- The type of watering (drip, sprinklers or both)
- Whether a pump or rainwater harvesting system is needed
Getting a fixed quotation
A fixed quotation is only possible after a site survey, because the available water supply and pressure determine what can be installed. A written, fixed quotation after survey includes a full equipment schedule, so you know exactly what the system will cost before any work begins.
Key Takeaway
Garden irrigation costs from £3,000 for a compact system to £40,000+ for a large estate — the number of zones, water source and garden size are the main price drivers, and a fixed quote requires a site survey.
Frequently Asked Questions
What is the typical cost of a garden irrigation system?
A typical private garden system in Surrey starts from around £3,000. Larger gardens and estates with multiple zones, pumps and rainwater harvesting range from £15,000 to £40,000 or more.
Why can't I get a price without a survey?
The available water pressure and flow at your property determine how many zones the system can have and whether a pump is needed. A survey lets us design correctly and quote a fixed price.
Does a bigger garden cost proportionally more?
Not always. Larger gardens benefit from economies of scale on pipework and equipment, but they need more zones, larger mainlines and potentially a pump or tank, which adds cost. The per-zone cost typically decreases as the system grows.
Is irrigation design included in the price?
For installed projects, design is included in the quotation. Stand-alone design without installation is quoted separately.
