Wildflower & BNG Seeding Contractors UK
Specialist wildflower and BNG seeding for housing developers, councils, infrastructure schemes and ecological restoration
CDTS North & West delivers wildflower and BNG seeding for housing, infrastructure, public realm and land restoration projects across the UK. We work from ecologist specifications or agreed habitat plans, selecting the right application method for each site to help clients meet planning conditions and establish species-rich habitat.
What Wildflower & BNG Compliance Delivers On Site
Wildflower and BNG seeding creates species-rich habitats that support pollinators, meet mandatory biodiversity net gain requirements, and provide long-term ecological value. Native seed mixes establish permanent grassland communities tailored to local soil and climate conditions. Proper establishment reduces weed competition, prevents erosion, and creates self-sustaining habitats that score well on Defra metrics while fulfilling 30-year management obligations.
BNG Compliance
Habitats established to Defra metric standards, supporting mandatory 10% net gain requirements with evidence-based seeding plans, species lists and establishment monitoring for planning approval and sign-off.
Pollinator Habitat
Native wildflower communities providing nectar and pollen sources throughout the growing season. Species-rich grasslands support declining butterfly, bee and beneficial insect populations while creating visible biodiversity.
Long-Term Value
Correctly established meadows require minimal maintenance compared to amenity grass, with annual hay cuts replacing weekly mowing. Lower fertility management reduces long-term costs while sustaining biodiversity.
Where Wildflower & BNG Seeding Fits On Your Project
Wildflower and BNG seeding applies wherever developments must deliver biodiversity net gain, create compensatory habitat, or establish permanent ecological value. The method suits sites from small urban verges to large-scale land restoration, on flat amenity areas or challenging slopes. We tailor seed mixes, application methods and aftercare regimes to match site conditions, planning requirements and adoption specifications.
Whether you're managing road verges requiring low-maintenance biodiversity, housing developments needing BNG compliance for planning approval, or restoration sites where native habitat creation fulfils ecological obligations, our approach combines technical seeding capability with understanding of habitat establishment requirements.

Why Choose CDTS North & West For Your Project
Wildflower projects fail when contractors lack experience with site preparation, use inappropriate seed mixes for local conditions, or cannot advise on the management regime needed for establishment. Generic grass contractors overseed at wrong rates, ignore fertility requirements, or fail to control aggressive weeds in year one. Planning conditions remain unmet, BNG metrics aren't achieved, and meadows revert to rank grass within two seasons.
CDTS North & West removes these risks through 30+ years establishing wildflower habitats. We prepare seedbeds to specification, source appropriate native mixes, apply at correct rates using hydroseeding or conventional methods, and provide establishment guidance that ensures success rates meeting both ecological and contractual requirements.
Full method flexibility
Hydroseeding distributes seed evenly on slopes and large areas. Conventional broadcast or drill seeding suits accessible flat sites. Direct application of brush-harvested seed maintains local genetics. We match method to site conditions and programme requirements.
30+ years ecological experience
CDTS North & West holds CHAS accreditation and carries £5 million public liability and £10 million employers liability insurance. Full RAMS provided for every project.
Full equipment range for any terrain
From large agricultural tractors for open restoration sites to compact pedestrian units for restricted-access areas, our equipment handles sites where standard contractors can't operate.
How Our Wildflower & BNG Seeding Process Works
01
Site assessment & specification
We review drawings, soil conditions, planning requirements and BNG metric targets, then specify appropriate seed mixes, application methods and establishment protocols aligned with your ecologist's requirements or planning conditions.
02
Ground preparation
We check substrate fertility and weed burden. Wildflowers establish best on low-fertility soils, so we may recommend reducing topsoil depth, using subsoil seedbeds, or targeted herbicide application to control aggressive species before seeding.
03
Seed sourcing & application
We source native UK wildflower mixes suited to local conditions, or harvest seed from donor sites using our brush harvester for local-provenance establishment. Application uses hydroseeding for slopes and large areas, or conventional broadcast/drill for accessible sites.
04
Establishment monitoring
First-season management is critical. We provide guidance on controlling invasive weeds, timing initial cuts to reduce fertility, and monitoring for establishment success. Properly managed meadows develop into diverse, self-sustaining habitats meeting BNG obligations.
We have collaborated for many years with CDTS on a whole range of seeding projects covering conventional seeding, hydroseeding and wildflower seeding for BNG enhancement. Extremely professional with highly experienced and qualified teams. Great communication, flexible and reactive service!

We engaged with CDTS for the hydroseeding across 4000 square metres of banks at a project in Blyth for Stainforth Construction. The team responded quickly and communication was good. Despite a small machinery hiccup, the hydroseeding was completed on time in just one day. Good service, good communication throughout, and completed professionally, on time. Seeds are just starting to germinate, we will update progress when we return to site.

Frequently Asked Wildflower & BNG Seeding Questions
What is Biodiversity Net Gain and does it apply to my project?
Biodiversity Net Gain (BNG) is a legal requirement under the Environment Act 2021. Most new developments in England must deliver a minimum 10% net gain in biodiversity, measured using the Defra Biodiversity Metric. This typically means creating or enhancing habitats — such as wildflower meadows, species-rich grasslands, or wetland margins — either on-site or off-site to offset habitat lost during construction. If your project requires planning permission, it almost certainly requires a BNG plan.
When is the best time to sow wildflowers?
In the UK, wildflower seeding is generally carried out in spring or autumn, when soil temperatures and moisture levels support germination. Autumn sowing allows seeds to overwinter naturally and often produces the strongest first-year establishment. However, hydroseeding extends the viable window because the mulch layer retains moisture and protects seed — giving more flexibility around your programme. We'll advise on the best timing based on your site conditions and project deadlines.
Why does site preparation matter so much for wildflower seeding?
Wildflowers are naturally outcompeted by aggressive grasses, nettles, and other vigorous weeds on fertile soils. Successful establishment depends on creating a clean, low-fertility seedbed with minimal weed pressure before any seed goes down. This may involve stripping topsoil back to subsoil, multiple rounds of cultivation and herbicide treatment to exhaust the existing weed seed bank, and creating a fine, open tilth. Skipping or rushing this stage is the single most common reason wildflower schemes fail.
Can you work from our ecologist's specification?
Yes. We routinely work to specifications provided by project ecologists, landscape architects, and environmental consultants. If your BNG plan or ecological mitigation strategy defines specific habitat types, target species, or sowing rates, we implement exactly what's specified. We can also advise during the design phase on what's practically achievable given your site conditions, substrate type, and programme — helping ensure the BNG plan is realistic before it becomes a planning condition.
How long does a wildflower meadow take to establish?
Expect visible germination within two to four weeks during growing season, with a recognisable wildflower sward developing over the first full growing season. However, a genuinely species-rich meadow develops over several years as perennial species mature and the community diversifies. First-year results often include annual "nurse" species that provide quick colour and ground cover while the slower perennials build root systems. Managing expectations is important — the best wildflower meadows are built over time, not overnight.
Do you work across the whole of the UK?
Yes. CDTS North & West is based in Cheshire and operates nationwide. We work with Tier 1 contractors, house builders, local authorities, and environmental consultancies on projects across England, Wales, and Scotland.
