Do you Need a Preliminary Roost Assessment (PRA) in Ilkeston?
In Ilkeston, a Preliminary Roost Assessment (PRA) is often required for homeowner projects such as loft conversions, roof alterations, barn conversions or other structural works where buildings could provide bat roost features. Erewash Borough Council will normally require confirmation that bats are not present, or that suitable mitigation is in place, before works can proceed.
For development proposals in Ilkeston, PRAs are commonly needed where buildings, trees or structures may be affected. Planning officers rely on early, robust ecological evidence to assess bat risk and determine whether further surveys are required, particularly for housing, regeneration and infrastructure schemes. Submitting a PRA at an early stage helps avoid seasonal survey delays, design changes and unexpected licensing issues.
Across Ilkeston, Preliminary Roost Assessments are most commonly requested where development affects:
- Older housing stock in areas such as Cotmanhay, Kirk Hallam, Hallam Fields and the town centre, where roof voids, tile gaps and cavity walls often provide bat roost features.
- Conversions or redevelopment of former agricultural buildings and outbuildings on settlement edges and surrounding rural fringe locations.
- Regeneration and brownfield sites around former industrial land and redevelopment areas where disused structures remain within development layouts.
- Sites close to river and green corridors, particularly along the River Erewash, the Erewash Canal, associated waterways, mature trees and hedgerow networks used by bats for commuting and foraging.
PRA requirements in Ilkeston are routinely assessed at validation wherever buildings or trees show potential bat roost features.
We carry out Bat Dusk Emergence Surveys throughout Ilkeston, covering urban sites, residential areas and the wider rural landscape.
Why Ilkeston Planning Authorities Request Preliminary Roost Assessments
Ilkeston planning authorities require Preliminary Roost Assessments wherever buildings, trees or structures show potential bat roost features, ensuring compliance with the Wildlife and Countryside Act 1981, the Conservation of Habitats and Species Regulations 2017, and national planning policy. Without a PRA, planners cannot lawfully determine whether further bat surveys or licensing are required, and applications in Ilkeston commonly face validation delays, additional ecological conditions or seasonal survey constraints.
Where an Ilkeston project involves demolition, conversion or structural alteration, PRA evidence should be confirmed before the application reaches validation to avoid delay or the need for further surveys.
