If you are planning a development project in West Yorkshire, you will likely need to account for protected wildlife before your local council will validate your plans.
Across Leeds, historic buildings, rural structures and urban green spaces provide ideal habitats for many species of native bats.
As all native bat species and their resting places are protected species under the Conservation of Habitats and Species Regulations 2017, local councils must ensure development proposals do not harm them.
Whether you are converting a stone barn in Horsforth or renovating a commercial building near the River Aire, working with qualified ecological consultants over the course of a bat survey ensures you meet all statutory requirements and expectations from Leeds City Council to obtain planning permission without unnecessary delays.
When you submit planning applications to your local planning authority, planning officers will evaluate whether your site could host roosting bats.
Local authorities across Leeds regularly ask for ecological surveys to support development proposals on sites with older roofing, dark voids or mature trees.
Our team conducts a thorough initial site visit to carry out bat scoping surveys, also known as a preliminary roost assessment (PRA).
During this visit, an experienced ecology consultant will start the bat survey process by inspecting the interior and exterior of all structures for evidence of bat roosts.
If no features are found on your Leeds site, we prepare a final report for the local council. Alternatively, if potential features are identified, we will outline the necessary further surveys required to move your project forward.
When an initial inspection shows potential for bats, secondary phase survey work must be carried out to confirm presence or absence.
During the active summer months, we conduct bat emergence and re-entry surveys (BERS) to monitor potential entry points at dusk and dawn.
Over the course of the numerous bat surveys we undertake across Leeds every year, our team uses modern bat detectors to record echolocation calls, identifying exact species and activity levels.
For larger sites across West Yorkshire, we also carry out bat activity surveys to map key foraging routes and commuting corridors.
Additionally, if your proposed development site contains underground vaults, cellars or stone arches, a specialised bat hibernation survey may be required during the winter to check for overwintering bats before construction begins.
If our assessments confirm that bats are using your site, your planning project can still proceed safely and legally.
We work alongside local interest groups like the West Yorkshire Bat Group and consult records from nearby designated sites to design suitable mitigation measures.
The plans often include installing bat boxes or preserving key access points to maintain local populations. If a known roost must be modified, our team will help you apply for a Natural England bat licence so your work remains fully compliant with the law.
