Waterlogged garden or field?

What do land drainage contractors charge?

A garden land drain or French drain typically costs £50–£100 per metre installed (typical 2026 quotes), so a 20–30 metre run usually lands between £1,000 and £3,000. Field drainage for farms is priced per scheme, not per metre, and honest contractors will say so. Tell us about the wet ground and local drainage contractors will quote their price for the job.

Typical land drainage costs, 2026

Last updated

What garden and field drainage work typically costs. These are typical quote ranges observed across the UK market in 2026, not fixed prices; ground conditions, access and where the water can be sent move the figure.

Ranges reflect typical quotes for domestic land drainage work observed across the UK market in 2026; they vary by region, soil, access and outfall. The small-garden scheme figure is derived from the per-metre range (20–30 m at £50–£100/m). Agricultural field drainage is priced per scheme or per hectare and varies too much for an honest headline figure, so none is given. Get exact prices for your ground via the form above.

The questions we get

How much does land drainage cost?

Garden land drains and French drains typically cost £50–£100 per metre installed (typical 2026 quotes), so a 20–30 metre garden scheme usually totals £1,000–£3,000. Agricultural field drainage is priced per scheme or per hectare after walking the land; it varies too much for one headline figure.

What does a land drainage contractor actually do?

Design and dig drainage that moves water off your ground lawfully: trenching, perforated pipe, gravel and membrane for gardens; designed mains and laterals for fields; plus the outfall, the part that decides whether any of it works. Good contractors also handle or advise on watercourse consents.

Do I need consent to work on a ditch or stream?

Works in an ordinary watercourse, culverts, dams and similar obstructions, need consent from the lead local flood authority or internal drainage board under the Land Drainage Act 1991. Main rivers are consented by the Environment Agency instead. Ask the council's flood risk team before touching any watercourse.

Whose job is it to maintain the watercourse on my boundary?

Yours, in part: riparian owners are expected to maintain the bed and banks of watercourses on or adjoining their land and keep flow unobstructed, per gov.uk guidance on owning a watercourse. On a boundary ditch, responsibility commonly runs to the middle from each side unless deeds say otherwise.

Is this quote service really free?

Yes, free to you, with no obligation to accept any quote. We pass your details only to relevant local drainage contractors, who quote you directly; we may receive a fee from those providers, which is how the service is funded.
