Hydroseeding Cost Calculator: Estimate Your UK Project Cost

Use this calculator to estimate the cost of hydroseeding your site. It uses live 2026 commercial rates from CDTS North & West — not industry averages or US pricing.

Enter your total area, select your specification and site conditions, and get an indicative budget figure in seconds.

01 — The Tool

Three inputs, one indicative figure.

The calculator uses the published per-m² rates from CDTS North & West to generate an indicative cost range for your project. It is not a quotation — it is a budget planning tool.

For sites under 2,000 m², the tool switches automatically to a day rate. At that scale, mobilisation and setup represent a larger share of total cost, so a day rate is more practical than per-m² pricing.

Area — larger contiguous sites trend toward the lower end of the rate range. Sites above 10,000 m² benefit from better economies of scale.

Access — determines which hydroseeder can reach the work area. Lorry-mounted units are faster and cheaper; towed units and long hose runs push the rate up.

Slope — affects specification. Beyond 3:1 (18°), BFM or EFM products are usually required in place of standard hydroseeding.

Figures exclude VAT. For a full breakdown by project type and specification, see our hydroseeding cost guide.

Hydroseeding indicative pricing

Based on CDTS North & West 2026 commercial rates.

Area to be hydroseeded (m²) 01

Total area in square metres. If you have multiple separate areas, enter the combined total.

Application type 02

Site access 03

Good: lorry-mounted hydroseeder can reach the site. Moderate: some vehicle restrictions. Restricted: towed unit or long hose runs required.

Steepest slope on site 04

Slopes steeper than 3:1 (18°) typically require BFM/EFM erosion control rather than standard hydroseeding.

All figures are indicative estimates based on CDTS North & West 2026 commercial rates and assume standard site conditions. Actual pricing depends on specification, seedbed condition, slope, access, travel distance, seed mix and project programme. Figures exclude VAT. This calculator is intended for budgeting purposes only and does not constitute a quotation. For accurate project pricing, request a quote.

02 — Methodology

How this estimate is calculated.

Three inputs determine where your estimate sits within the published rate range for your chosen specification. The calculator uses the same rate ranges CDTS North & West applies to live commercial quotes.

DRIVER 01

Area affects unit cost

Larger contiguous areas are more efficient to treat, so the per-m² rate trends toward the lower end of the range on bigger sites. The 6,000L lorry-mounted hydroseeder treats 2–3 hectares per day at peak throughput, so sites above 10,000 m² benefit from better economies of scale.

Effect — unit rate ↓ as area ↑

DRIVER 02

Access determines equipment

Site access determines which hydroseeder can reach the work area. If a lorry-mounted unit can access the site directly, application is faster and the rate is lower. If vehicle restrictions mean a smaller towed unit is required, or if long hose runs are needed, the rate sits higher in the range.

Effect — restricted access ↑ rate

DRIVER 03

Slope affects specification

Standard hydroseeding is typically viable on slopes to 3:1 (18°). Steeper gradients usually require a Bonded Fibre Matrix (BFM) or Engineered Fibre Matrix (EFM) product, which costs more due to the specialist mulch materials needed to form a continuous erosion-resistant matrix.

Effect — steep slope ↑ specification & rate

The 2,000 m² threshold

For sites under 2,000 m², the calculator switches to a day rate. At that scale, mobilisation and setup represent a larger share of total cost, so a day rate is more practical than per-m² pricing. The day rate covers mobilisation, all materials and application. For a full breakdown of pricing by specification, project size and cost drivers, see our hydroseeding cost guide.

03 — Intended Use

When to use this calculator.

This tool is designed for early-stage budgeting. It is most useful when you are writing a cost plan, comparing seeding methods, or sense-checking a contractor quote against published rates.

Use it for

Early-stage budgeting

Preliminary budget estimates
Cost plan line items
Like-for-like method comparisons (turfing & erosion blankets shown)
Establishing whether hydroseeding is viable before formal quotes

Do not use it as

A substitute for a site-specific quote

Seedbed condition
Travel distance from our Cheshire base
Programme constraints
Soil amendments & specific seed mix requirements

Every project has variables the calculator cannot account for. For accurate project pricing, send us your drawings.

04 — Quick Guide

Which application type should I select?

If you are unsure which option to choose in the calculator, use this quick guide. The calculator's slope advisory will also flag when your inputs suggest a different specification may be needed.

Select

Amenity grass

If your specification calls for a standard grass mix on slopes no steeper than 3:1 (18°). This covers the majority of housing, SuDS and general revegetation work.

Select

Wildflower / BNG

If your ecologist or planning condition requires a species-rich grassland or wildflower meadow habitat. Seed costs are significantly higher, which is reflected in the rate range.

Select

BFM / EFM erosion control

If slopes are 2:1 (27°) or steeper, or if erosion protection during establishment is the primary requirement on the site.

Still unsure

We'll advise on the right specification

05 — Common Questions

Frequently asked questions.

Quick answers to the questions we hear most often from procurement managers, site managers and specifiers using this calculator.

The calculator uses the same rate ranges CDTS North & West applies to live commercial quotes. The estimate will be in the right order of magnitude for budget planning. However, actual project pricing depends on factors the calculator cannot assess, including seedbed condition, travel distance, programme timing and specific seed mix costs. Treat the output as an indicative budget range, not a fixed price.

No. All figures produced by the calculator exclude VAT. The day rate for sites under 2,000 m² is also quoted excluding VAT.

Run the calculator separately for each area and specification. For example, if you have 3,000 m² of amenity grass embankments and 1,500 m² of steep slopes requiring BFM, calculate each separately. For a combined quote covering multiple specifications, request a quote and we will price each element.

An approximate figure is fine for budgeting. If you have site drawings, you can scale off the plans or use a free tool such as Google Earth's measurement feature. If you are unsure, enter a round estimate and run the calculator at a few different areas to see how cost scales.

For areas under 2,000 m², mobilisation and equipment setup represent a larger proportion of the total cost. A day rate of £1,280 to £2,100 plus VAT is typically more practical and better value than per-m² pricing at that scale. The day rate covers mobilisation, all materials and full application.

Yes. The calculator results include a comparison panel showing what turfing and installed erosion control blankets would cost for the same area. For a more detailed method-by-method comparison including conventional drill seeding, coverage rates and slope limits, see our hydroseeding cost guide or hydroseeding vs conventional seeding comparison.

Next Step

Discuss your seeding project with a specialist.

Not sure if hydroseeding is right for your site conditions? Share your drawings, photos or specification and our technical team will assess your project, confirm the most appropriate seeding method, and provide a detailed quote. For sites with both flat areas and slopes, we can recommend a combined conventional and hydroseeding approach to optimise cost and programme. See our UK hydroseeding services for full capability details.
