Expert Bat Surveys in Hertfordshire
Crossman Ecology provides professional bat surveys throughout Hertfordshire for homeowners, developers, architects, planning consultants and commercial clients. Whether you’re converting a traditional barn, extending a period property, redeveloping a commercial site or bringing forward a larger residential development, we provide practical ecological advice that helps your planning application progress efficiently.
Hertfordshire’s varied landscape of ancient woodland, chalk streams, farmland and historic towns provides excellent habitat for a wide range of bat species. As a result, bat surveys are frequently required to accompany planning applications across the county. Our experienced ecologists combine technical expertise with local knowledge to deliver reliable, proportionate advice tailored to your project.
When is a Bat Survey Required?
Local planning authorities across Hertfordshire may require a bat survey where development has the potential to affect bats or their roosts. Surveys are commonly required for:
- Barn conversions and agricultural redevelopment.
- Extensions and alterations to older buildings.
- Loft conversions and roof replacement works.
- Demolition of residential, commercial and industrial buildings.
- Residential and commercial development sites.
- Tree works affecting mature trees with bat roost potential.
All surveys are undertaken in accordance with the latest Bat Conservation Trust guidance and Natural England best practice, ensuring planning applications are supported by robust ecological evidence.
Local Planning Knowledge Across Hertfordshire
Crossman Ecology believes that local knowledge is essential to successful project delivery. We take the time to understand the planning policies and ecological requirements of Hertfordshire’s planning authorities, including Broxbourne Borough Council, Dacorum Borough Council, East Hertfordshire District Council, Hertsmere Borough Council, North Hertfordshire District Council, St Albans City and District Council, Stevenage Borough Council, Three Rivers District Council, Watford Borough Council, Welwyn Hatfield Borough Council and Hertfordshire County Council where appropriate. This local understanding enables us to provide practical ecological advice that reflects local planning policies and environmental priorities.
Protected Sites in Hertfordshire
Hertfordshire contains a wealth of nationally important wildlife sites, including the Chiltern Beechwoods Special Area of Conservation (SAC), which extends into the western edge of the county and protects internationally important beech woodland habitats. Together with the county’s extensive ancient woodlands, chalk streams, river valleys and numerous Sites of Special Scientific Interest (SSSIs), these landscapes provide valuable habitat and commuting routes for bats. Crossman Ecology has extensive experience assessing development proposals close to designated sites throughout Hertfordshire, helping clients navigate ecological constraints with confidence.
