Garden Sprinkler & Irrigation Repair Costs 2026
Most irrigation faults are one failed component, not a failed system. Published component pricing runs £15–£300 depending on the part, and general garden labour is published at £14–£25 an hour — so a typical single-fault repair sits far below the £600–£3,000 published cost of a new install.
The faults behind the symptoms
| Symptom | Usual cause | Published parts range |
|---|---|---|
| One zone dead | Zone valve or its cable | £15–£300 per component |
| Heads not rising | Pressure loss or debris | Heads at the low end of £15–£300 |
| Wet patch, pressure drop | Split pipe or joint | Fittings at the low end; labour is the cost |
| Controller dark or stuck | Controller / transformer | Controllers to £300 (Hunter, Rain Bird published) |
| Drip line dry at the end | Blocked emitters or split tube | Pennies — usually DIY |
If the fix keeps not holding, price the alternative on the irrigation install guide or the calculator.
Repairing in a ban year
Nine water companies have hosepipe bans in force this summer, and mains-fed sprinklers are restricted under them — but a repair visit is still worth booking: a system that leaks wastes stored water too, and converting a repaired system to run drip from a water butt makes it ban-proof.
Sprinkler repair FAQs
Usually a stuck or failed zone valve, a cut cable to it, or a controller fault. Component pricing is published at £15-300 depending on the part; the diagnosis is the skilled bit, which is why a specialist visit beats guess-and-replace.
Low pressure (a leak upstream, a part-closed valve or a clogged filter) or debris in the head itself. Heads are among the cheaper published components; a run of them failing together points at pressure, not the heads.
If the pipework is sound, repairs win — parts are modular and the published component range is £15-300. When a system needs re-zoning or the pipe runs themselves have failed, compare against the published install range of £600-3,000 before committing to a rebuild.
Blocked emitters and split feeder tube are genuinely DIY — parts cost pennies and push-fit. Anything at the valve box, the controller or the mains connection is where a professional earns their visit.
