Hydroseeding Cost Calculator: Estimate Your UK Project Cost
Laste Updated: April 2026
Written by James Thomson, Director at CDTS North & West
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.
UK Hydroseeding Cost Calculator
Indicative pricing from CDTS North & West, based on 2026 commercial rates
Total area in square metres. If you have multiple separate areas, enter the combined total.
Good: lorry-mounted hydroseeder can reach the site. Moderate: some vehicle restrictions. Restricted: towed unit or long hose runs required.
Slopes steeper than 3:1 (18°) typically require BFM/EFM erosion control rather than standard hydroseeding.

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.
Three inputs determine where your estimate sits within the published rate range for your chosen specification.
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 to 3 hectares per day at peak throughput, so sites above 10,000 m² benefit from better economies of scale.
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.
Slope affects specification. Standard hydroseeding is typically viable on slopes to 3:1 (18 degrees). 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.
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.

How this estimate is calculated
EROSION CONTROL SPECIALISTS
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: preliminary budget estimates, cost plan line items, like-for-like method comparisons (the calculator shows turfing and erosion control blanket costs for the same area), and establishing whether hydroseeding is viable for your site before requesting formal quotes.
Do not use it as: a substitute for a site-specific quote. Every project has variables the calculator cannot account for, including seedbed condition, travel distance from the CDTS North & West base in Cheshire, programme constraints, soil amendments and specific seed mix requirements. For accurate project pricing, send us your drawings.
When to use this calculator
BNG SEEDING SPECIALISTS
If you are unsure which option to choose in the calculator, use this quick guide.
Select amenity grass if your specification calls for a standard grass mix on slopes no steeper than 3:1 (18 degrees). 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 degrees) or steeper, or if erosion protection during establishment is the primary requirement.
If you are still unsure, the calculator's slope advisory will flag when your inputs suggest a different specification may be needed. For a full breakdown of what each specification includes and how it is priced, see our hydroseeding cost guide.

Frequently Asked Questions
How accurate is 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.
Does the estimate include VAT?
No. All figures produced by the calculator exclude VAT. The day rate for sites under 2,000 m² is also quoted excluding VAT.
What if my site has multiple application types?
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.
What if I do not know my exact area?
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.
Why does the calculator show a day rate for small sites?
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.
Can I use this to compare hydroseeding against other methods?
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.
Discuss Your Conventional Seeding Project
Not sure if conventional seeding 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.
