CDTS North & West delivers hydroseeding, wildflower establishment, erosion control and cable-trench reinstatement on ground-mounted solar farms across the UK. From 5 MW community schemes to 500 MW+ NSIPs, we provide the specialist seeding capability that EPC contractors and solar developers need to discharge CEMP, LEMP and BNG conditions on programme.
The UK needs to commission approximately 3 GW of new ground-mounted solar capacity every year to reach its 47 GW target by 2030. Since December 2025, the NSIP threshold for solar in England has risen from 50 MW to 100 MW, opening a wave of sub-100 MW schemes consented through local planning authorities. Every one of those projects carries vegetation, BNG and CEMP conditions that must be discharged before commercial operation.
The pressure points are familiar to any EPC contractor or developer managing a solar construction programme. Construction strips and compacts topsoil across access roads, cable routes and compound areas. Planning conditions require a Landscape and Ecological Management Plan (LEMP) delivering a minimum 10% Biodiversity Net Gain, secured for 30 years. Landowners expect full agricultural reinstatement at decommissioning. And the programme window between civil works completion and grid connection leaves limited time to establish vegetation.
Solar farm construction creates distinct vegetation zones, each with different access constraints, soil conditions and species requirements. Specialist seeding addresses every area.
The largest seeding area on any solar site. Inter-row spacing of 3 to 5 m with panel low-edge clearance of 0.8 to 1.2 m. Requires low-growing, shade-tolerant fine fescue-dominant grass mixes. Classified as "other neutral grassland" under the Statutory Biodiversity Metric.
Cable routes trenched to 600 to 1,000 mm depth and internal haul roads create strips of compacted, disturbed ground needing subsoil decompaction, topsoil replacement and seeding. On sloped batters, BFM erosion control prevents washout during establishment.
Surface water drainage features designed to CIRIA C753. Swales require vegetation maintained at 75 to 150 mm for hydraulic performance. Pond batters on slopes exceeding 3:1 need erosion-resistant establishment. Hydroseeding with BFM is the most practical technique.
Native hedgerow planting and wildflower buffer strips along site boundaries and watercourse setbacks (typically 10 m minimum). These strips combine hedgerow establishment with wildflower seeding to deliver BNG habitat units and visual screening.
Dedicated wildflower creation zones on field margins and areas outside the panel array. Typical specifications use Emorsgate EM2 or EM3 mixes (20% wildflower / 80% grass) at low sowing rates of 4 to 5 g/m². Uniform distribution of expensive seed mixes is critical.
Inverter stations, transformer pads, battery storage compounds and temporary construction laydowns require full reinstatement. These areas typically receive standard amenity grass mixes seeded over reinstated topsoil to BS 3882:2015.
CEMP conditions routinely require interim erosion control on exposed soils, stockpiles and cut slopes. Temporary hydroseeding with a nurse crop provides rapid cover that controls dust, prevents sediment runoff and meets GPP5/GPP6 pollution prevention requirements.
Six advantages that make hydroseeding the practical choice for post-installation seeding on solar farms.
This is hydroseeding's decisive advantage on solar sites. A hydroseeder applies slurry via hose from a truck parked on the access track, reaching 30 to 75 m+ into panel rows. Tractor-mounted drill seeders and power harrows cannot operate under installed panels with low-edge clearances below 1.2 m. CDTS North & West's 2,500L twin-axle towed hydroseeder is sized specifically for restricted inter-row access where lorry-mounted units cannot manoeuvre.
Hydroseeding delivers water, seed, paper/wood fibre mulch, starter fertiliser and tackifier in a single application. This addresses the classic post-construction problem: compacted subsoil with thin or imported topsoil and a poor seedbed. The mulch layer retains surface moisture, and the tackifier bonds seed to soil. One pass replaces what would otherwise require separate cultivation, seeding, fertilising and erosion protection operations.
Standard hydroseeding is effective on slopes to approximately 3:1. For steeper features — attenuation pond batters, bund faces, cable-route embankments — Bonded Fibre Matrix (BFM) extends capability to 1:1 (45 degrees) with up to 99% erosion reduction under controlled testing (Ricks et al. 2020). This can eliminate the need for separate jute or coir erosion control blankets (typically £2 to £6/m² supplied and fitted) on slopes where hydroseeding or BFM can be applied instead.
BNG wildflower seed is expensive (£30 to £200+/kg for 100% wildflower mixes) and sowing rates are low (1 to 5 g/m²). Hydroseeding uses green tracer dye to confirm visually uniform coverage, ensuring consistent seed-to-soil contact via the mulch layer. One pass applies mix, nurse crop, mulch and tackifier together — reducing waste and guaranteeing the even distribution that BNG habitat creation requires.
CDTS North & West's 6,000L lorry-mounted hydroseeder covers 2 to 3 ha per day; the 2,500L towed unit covers 1 to 1.5 ha per day in restricted areas. Multiple units can work in parallel on larger schemes, compressing the seeding critical path between civil works completion and commercial operation date (COD).
Not every zone on a solar farm needs hydroseeding. Flat, open, accessible areas — such as compound reinstatements and broad field margins where cultivation equipment can operate — may be more cost-effectively seeded using conventional drill or broadcast methods. CDTS North & West offers both hydroseeding and conventional seeding, and recommends the right method for each zone based on access, slope, soil condition and specification.
Since 12 February 2024, all Town and Country Planning Act major applications in England — including most sub-NSIP solar farms — must deliver a minimum 10% Biodiversity Net Gain secured for 30 years under the Environment Act 2021. BNG is phasing into NSIP solar projects from late 2025. The gain is measured using the Statutory Biodiversity Metric, and most solar developers voluntarily exceed 10% by a significant margin.
Typical BNG habitat delivery on solar farms involves converting low-distinctiveness arable or improved pasture baselines to modified grassland or other neutral grassland across inter-row and under-panel areas, supplemented by new native hedgerows, scrub planting and small ponds or scrapes. Under-panel habitat classified as "other neutral grassland of moderate condition" is the material classification for metric scoring, following Natural England guidance (TIN101).
CDTS North & West delivers the physical seeding, wildflower establishment and erosion control works to LEMP specification on behalf of developers, EPC contractors and ecologists. Our capabilities include wildflower and BNG seeding using native-provenance seed mixes, brush seed harvesting from local donor sites for provenance-matched habitat creation, and BFM erosion control on drainage features and slopes within the BNG delivery area.
