Top tips

Hiring a landscaper, without the regret.

Four moves that separate a smooth job from a nightmare.

Insist on a scaled drawing before quoting.

On anything over £5k, a measured drawing — even sketched — is the basis of a fair quote. Vague specs mean vague quotes that creep at every change.

Get the sub-base in writing.

On patios and paths, the sub-base (Type 1 MOT, compacted) is where the job lives or dies. If they're not specifying depths and grades, walk.

Plan drainage before planting.

Surface water needs somewhere to go — soakaway, French drain, slot drain. Adding it after the lawn's down is twice the price.

Hold 10% retention for one growing season.

Trees, hedges and lawn settle over a year. Hold 10% until you've seen one full season — that's when settlement, dying plants and bad drainage surface.

Landscaper explained

A garden pond looks simple but rewards proper engineering — wrong liner choice, undersized filter or no shelf for plants and the water goes green within months. Specialist landscapers know what to specify.

What's involved

  • Excavation with shelves for marginal plants
  • Underlay + EPDM or butyl liner (15+ year lifespan)
  • Pump, filter, UV clarifier sized to volume
  • Outdoor power supply (RCBO, IP68 cables) — Part P notifiable
  • Edging, plants and (if requested) fish stocking

Typical UK costs (2026)

ItemCost
Small wildlife pond (2×2m)£1,200–£2,800
Formal koi pond (4×3m)£3,500–£8,500
Rill / formal water feature£1,800–£5,500
Pre-formed pond install£700–£1,400

What to check

Liner type (EPDM lasts 30+ years, butyl 15+, PVC 8–10), pump turnover (whole pond volume every 2 hours), and that the outdoor electrics are Part P certified.
