TL;DR — Garden Irrigation Installation Cost At A Glance
- Most UK households pay £500–£1,500 to have drip and micro-irrigation installed across their beds, borders and pots in 2026. A single greenhouse or raised-bed kit fitted is £150–£500; a large planted garden on multiple zones runs £2,000–£4,000.
- Which guide do you want? This one is drip and micro-irrigation for planted areas — beds, borders, pots, hanging baskets, greenhouses and veg plots, watered by emitters at each plant. If you want pop-up sprinklers watering a lawn, our lawn irrigation cost guide is the page you need.
- Drip is priced by outlet and by metre, not by garden. Reckon on £3–£10 per linear metre of dripline installed, £8–£15 per fitted outlet on pots and baskets, and £250–£315 per planted zone on published UK figures. Below about fifteen outlets the minimum charge takes over instead.
- The controller is where automation starts. A timer is £30–£150, a mains irrigation controller fitted £120–£220, and a rain or soil-moisture sensor £20–£150.
- You may need an outside tap first — £80–£150 for a simple one off the kitchen sink wall, up to £1,000–£1,200 where pipework has to be buried across the garden.
- A permanent mains-fed system is notifiable to your water company under the Water Supply (Water Fittings) Regulations 1999, and drip lines need backflow protection beyond a standard double check valve. Check your water company's own requirement first — the fluid category it applies decides the valve. London and the South East run roughly 20–35% above the rest of the UK, with the labour element alone typically 15–25% higher.

Start here, because the wrong system is the most expensive mistake in this trade. Garden watering splits into two families that share almost no components.
Pop-up sprinklers throw water over turf. Heads sit flush in the lawn, pop up under pressure and cover 3–5m each, and they need mains pressure, solenoid valves, trenching across the lawn and a multi-zone controller, priced at around £700–£1,100 per zone. If that's your job, use our lawn irrigation cost guide — it prices sprinkler zones and whole-lawn systems properly, and this page deliberately doesn't.
Drip and micro-irrigation delivers water drop by drop at the base of individual plants through 13mm supply pipe, 4mm micro-tube and emitters. It works at low pressure, needs no trenching across turf, and can run off a water butt, priced at around £250–£315 per zone — roughly a quarter of a sprinkler zone. It's what beds, borders, pots, greenhouses and veg plots want, because it puts water in the root zone rather than on the leaves, and it cuts water use by 30–50%.

Garden Irrigation Cost By System Type
Micro-irrigation is modular, which is why per-outlet and per-metre pricing tells you more than a garden-size band does. Count your pots, measure your borders in metres, and the quote stops being a mystery.
| System type | What it waters | Rest of UK | London & South East |
|---|---|---|---|
| DIY micro-drip kit, supply only | 10–20 pots or a raised bed | £50–£150 | £50–£150 |

What Affects The Cost Of Garden Irrigation?
1. How Many Outlets And Metres Of Dripline
This is the dominant driver and the reason two "medium gardens" can differ by £700. Every dripper is a fitting, a length of micro-tube and a minute or two of someone's time — supply-only figures for drip tubing and emitters run £30–£80 on a basic system and £100–£200 on a multi-zone one. Installed dripline works out at £3–£10 per linear metre, which is what the system-type rows above imply. Forty pots is a genuinely bigger job than forty metres of border. If your list is instead "one lawn, four sprinkler zones", price it in our lawn irrigation cost guide — the components and the rates are different.
2. Mains Feed Versus Water Butt Or Pump
A mains-fed system is simplest to install and the most regulated. Under the Water Supply (Water Fittings) Regulations 1999 a fixed, automatic or permanently installed system normally requires notification to your water company, which then has ten working days to respond, and work should not start until consent arrives. A hose union tap needs a double check valve; a drip system watering borders or hanging baskets sits in fluid category 4 and needs a DB valve fitted above the highest dripper. Those categories come from Schedule 1 to the Regulations — check your own water company's stated backflow requirement, because it enforces them. Tank-and-pump systems land in category 5, where a compliant booster set is from £1,800 plus VAT for a 200 litre unit and from £2,210 for a 500 litre one, supply only. A water butt with a gravity feed or small pump — £50–£200 for the pump — sidesteps all of it, at the cost of pressure and volume.
3. Whether You Need An Outside Tap
No tap, no system. A straightforward outside tap on the kitchen-sink wall is £80–£150 all in, with the tap itself only £6–£30; run it to an adjacent wall and it's £180–£250; take it out into the garden and it's £300–£400; bury the pipework properly and it's £1,000–£1,200 over three to four days. Plumber day rates are £150–£270, with a £60–£80 minimum call-out and a £20–£60 London premium. Any garden tap set at 750–1,350mm depth also needs notifying to the water supplier.
4. Automation — Controllers, Sensors And Smart Kit
A tap timer at £25–£60 is the cheapest useful upgrade in the garden. A mains irrigation controller fitted is £120–£220, a premium unit £80–£150 supply-only, and solenoid valves £40–£100 each where zones need to run independently. Rain sensors are £20–£80 and soil-moisture sensors £20–£100 — worth it in the UK, where a system with no rain sensor will happily water a soaked border in October.
5. Trenching, Reinstatement And Winterisation
Drip lines sit on the soil surface under mulch, which is why drip is cheaper than sprinklers — no trenching across turf, no reinstatement. Where a supply pipe must cross a lawn or path, shallow trenching adds £60–£250 and ground preparation £50–£300. Then budget the annual cycle: winterisation £75–£125, a filter change £10–£30, an inspection £50–£100. Skipping the autumn drain-down splits filters, valves and emitters in the first hard frost.
6. Your Location
London and the South East run roughly 20–35% above the rest of the UK overall, with the labour element specifically 15–25% higher — the rest of the gap is access, parking and materials delivery. Installer day rates run £200–£350 across most of the UK, though some published figures for irrigation specialists run as high as £480–£720 per day, reflecting two-person teams rather than a general gardener — ask what the day rate buys before comparing quotes.
What's Included — And What's Not
A standard drip irrigation quote covers:
- A walk-round and layout plan: zones, outlet count and pipe runs
- 13mm supply pipe, 4mm micro-tube, emitters, stakes and fittings
- In-line filter and pressure regulator — both essential, not optional
- Connection to an existing outside tap, including a double check valve
- A tap timer or controller where specified, and programming it with you
- Commissioning: flushing the lines, setting each dripper, checking coverage
Charged as extras:
- A new outside tap — £80–£400, or £1,000–£1,200 for a buried run
- Water company notification and a category 4 DB valve or category 5 booster set
- Trenching under paths or lawn — £60–£250
- A pump for a water butt or tank feed — £50–£200
- Rain or soil-moisture sensors — £20–£100 each
- Additional solenoid valves for extra zones — £40–£100 each
- Annual winterisation and servicing — £75–£125
- Mulch over the lines, which you want and which is a separate materials cost
Can You Do It Yourself?
Micro-irrigation is one of the most genuinely DIY-able systems in the garden, and it would be dishonest to pretend otherwise.
A basic kit is £50–£150 and comes with enough tubing, emitters and fittings for a raised bed or twenty pots. It pushes together by hand — no soldering, no glue, no digging. One UK installer's own figures show a 0–100 m² garden at £100–£300 DIY against £200–£500 installed, and a 100–300 m² garden at £300–£700 DIY against £500–£1,200 installed. For pots on a patio and a greenhouse bench, a Saturday and a kit is the right answer.
Two things make it worth paying somebody. The first is hydraulics: emitters need a consistent pressure to deliver an even flow, so a run that's too long, a filter that's missing or a pressure regulator that's skipped gives you soaked plants at the tap end and dry ones at the far end. The second is compliance — a permanent mains connection is notifiable, and the fluid-category rules on drip systems are genuinely fiddly. Get that wrong and you have an unlawful connection on your water supply, not just a wonky border.
DIY is a poor idea on a multi-zone system with solenoid valves and a mains controller, and on anything fed from a tank or pump, where category 5 backflow protection applies.
How To Save Money On Garden Irrigation
- Start with one zone and extend it. Micro-irrigation is modular by design. A single planted zone at £250–£315 now, with the manifold sized for two more, costs far less than a four-zone system you haven't tested.
- Feed it from a water butt. Free water, no notification, no backflow valve, and a pump at £50–£200 if you need pressure. On a hosepipe ban it's the only system still running.
- Have it installed alongside other garden work. One mobilisation for irrigation, planting and mulch beats three visits — our garden renovation cost guide prices whole-garden packages, and irrigation is far cheaper laid before the mulch goes down than retro-fitted after.
- Fit a rain sensor, not a bigger controller. £20–£80 stops the system watering in the rain, which is where UK water bills on metered supplies actually leak.
- Do the winterisation yourself. Draining down, removing the timer and bringing the filter indoors is twenty minutes and saves the £75–£125 service charge.
- Mulch after installing. 50mm of mulch over the drip lines cuts evaporation, hides the pipe and reduces run times — so the system costs less to run for the same result.
How To Hire A Good Irrigation Installer
Ask them to state the outlet count and metres of dripline in the quote. Anyone quoting a flat "£900 for the garden" without counting drippers hasn't designed anything, and you won't be able to compare their price with anyone else's.
Check they know the water regulations. The right answer to "what backflow protection are you fitting?" is a specific one — a double check valve on the hose union tap, plus a DB valve above the highest dripper on a category 4 drip system — not "it'll be fine". Ask whether they'll notify your water company for a permanent installation.
A proper quote lists the zones and what each one waters, the outlet count, the filter and pressure regulator, the controller model, whether an outside tap is included, and the winterisation arrangement for year one. Look for BALI or APL membership for garden work generally, and public liability insurance of at least £1m.
Red flags: no filter and no pressure regulator in the parts list; pop-up sprinklers and drip lines specified on the same zone, which cannot work because the two need different pressures and run times.

Frequently Asked Questions
How Much Does A Drip Irrigation System Cost In The UK?
A DIY kit is £50–£150. Professionally installed, expect £150–£500 for a greenhouse or raised beds, £200–£500 for the borders of a garden under 100 m², £500–£1,200 for 100–300 m², and £1,200–£2,500 for 300–500 m². Published figures price a single planted zone at £250–£315, or £3–£12/m² by area.
What's The Difference Between Drip Irrigation And A Sprinkler System?
Drip delivers water at the base of individual plants through emitters, works at low pressure and suits beds, borders, pots and greenhouses. Sprinklers throw water over an area, need mains pressure and trenching, and suit lawns. The cost gap is large — drip runs around £250–£315 per zone against £700–£1,100 for sprinklers. For lawn systems, see our lawn irrigation cost guide.
Do I Need Permission To Install A Garden Irrigation System?
You don't need planning permission, but a fixed, automatic or permanently installed mains-fed system normally requires notification to your water company under the Water Supply (Water Fittings) Regulations 1999. They have ten working days to respond and work should not start before consent. Hand-operated systems are generally exempt. Drip systems also need category 4 backflow protection under Schedule 1 to the Regulations — a DB valve above the highest dripper. Confirm it with your water company, which is the enforcing authority.
Can I Run An Irrigation System From A Water Butt?
Yes, and it's the smartest option in a drought. A gravity feed works for low-level drippers below the butt outlet, costing £120–£300 fitted; add a small pump at £50–£200 for proper pressure and a rise. Water-butt systems need no water company notification and keep working during a hosepipe ban. The limit is volume — a 200L butt doesn't water a large garden for long.
How Much Does It Cost To Winterise An Irrigation System?
Annual cleaning and winterisation is £75–£125 in the UK, with a filter replacement at £10–£30 and a bi-annual system inspection at £50–£100. It means draining the lines, removing and storing the timer and filter, and isolating the tap. Doing it yourself takes about twenty minutes on a surface-laid drip system, which is one of drip's advantages over buried sprinkler pipework.
Does Drip Irrigation Save Water?
Yes, measurably — published figures put the saving at 30–50% against hose or sprinkler watering, because water goes into the root zone rather than onto leaves and paths, and there's no wind drift or overspray. On a metered supply that's the main financial case for the system. A rain sensor at £20–£80 adds to the saving by stopping unnecessary cycles.
How Long Does Installation Take?
A basic drip system is 2–6 hours. A small garden takes about a day, a large automated system two to three days, and a multi-zone system two to four. Labour costs follow the same pattern: £100–£250 for a basic drip system with one installer, up to £800–£4,200 for a multi-zone install. Adding an outside tap adds half a day, or three to four days for a buried run.
