Do you Need a Preliminary Roost Assessment (PRA) in Shropshire?
If you’re a homeowner, a PRA is typically required where loft conversions, roof replacements, barn conversions or structural alterations affect buildings with any potential bat roost features. Shropshire councils will usually seek confirmation that bats are not using the structure before works proceed.
For developers, PRAs are required where existing buildings, trees or structures form part of a planning submission and planners need early, defensible evidence of bat risk before determining whether further surveys are necessary. This commonly affects housing schemes, conversions, infrastructure upgrades and regeneration sites.
Early confirmation at PRA stage prevents seasonal bottlenecks, redesign and unexpected licensing risk.
Across Shropshire, Preliminary Roost Assessments are most frequently requested where development interacts with:
Historic town centres such as Shrewsbury and Ludlow, where older buildings, loft spaces, and roof tiles create potential roost sites
Rural farmsteads and barns in areas like North Shropshire and South Shropshire, particularly where redundant or partially used outbuildings remain
Small-scale brownfield or regeneration sites in Telford, Bridgnorth, and Market Drayton, where older structures are retained amidst new layouts
Natural and semi-natural features including river corridors (Severn, Teme), canals (Shropshire Union Canal), hedgerows, and woodland patches that intersect development zones
PRA requirements are routinely tested at validation wherever bat roost potential exists.
Our Bat Dusk Emergence Survey services cover the whole of Shropshire, from urban centres to rural landscapes.
Why Shropshire Planning Authorities Request Preliminary Roost Assessments
Shropshire planning authorities require PRAs wherever buildings, trees or structures present any credible roost potential to ensure compliance with the Wildlife & Countryside Act 1981, the Conservation of Habitats and Species Regulations 2017, and national planning policy. Without a PRA, planners cannot lawfully determine whether emergence surveys or licensing will be required. Where early evidence is missing, applications commonly face validation blocks, additional ecological conditions or forced seasonal delay.
If a Shropshire project involves demolition, conversion or structural alteration, PRA evidence should be confirmed before the application reaches validation.
Local Case Insight
The Preliminary Roost Assessment Process
Our Preliminary Roost Assessments in Shropshire provide fully compliant reports accepted by local planning authorities. It prevents avoidable emergence delays, stabilises planning submissions and ensures that any further survey requirements are proportionate and justified.
Key Deliverables for Shropshire Projects
Where bat scoping is required to unlock planning in Shropshire, a PRA provides:
a legally defensible preliminary roost assessment report
confirmed classification of roost potential
identification of whether emergence surveys are required
early determination of licensing likelihood
documentation structured for Staffordshire LPA review
The outcome is certainty, not escalation.
Step 1
Programme & Scoping
Proposed works, construction sequence and planning feedback are reviewed to define PRA scope.
Step 2
Daytime Roost Inspection
Inspection of buildings, structures or trees for roost features and bat evidence in line with lawful survey guidance.
Step 3
Assessment
Roost potential classification and planning implications interpreted against LPA validation requirements.
Step 4
Reporting & Integration
Evidence is reported for planning submissions and coordinated with Bat Emergence Surveys or PEAs where required.

FAQ - Preliminary Roost Assessments in Shropshire
What is a Preliminary Roost Assessment in Shropshire?
A Preliminary Roost Assessment is a daytime bat survey undertaken by a qualified ecologist to determine whether a building or structure has potential to support roosting bats. It is commonly required to support planning applications involving building alterations or conversion.
Do barn conversions in Shropshire require a PRA?
In most cases, yes. Agricultural barns and traditional outbuildings often contain features suitable for bats, such as open roof voids or gaps in stonework. Local Planning Authorities frequently request a Preliminary Roost Assessment before determining conversion proposals.
Planning validation requirements can be viewed via Shropshire Council:

Is a PRA needed for listed buildings or properties in conservation areas?
Yes, if works affect the roof, loft space or structural fabric. Heritage status does not remove the need to assess potential impacts on protected species such as bats.
Can a Preliminary Roost Assessment be carried out on agricultural sheds?
Yes. Modern sheds may have lower bat roost potential, but an assessment is often required where demolition or alteration is proposed, particularly in rural settings.
Does a PRA include inspection of timber framed or stone buildings?
Yes. Traditional timber framed or stone buildings are inspected internally and externally to identify crevices, gaps or voids that may support bat roosting.
What happens if no bat evidence is found?
If no evidence is found and the building has negligible bat roost potential, the report will confirm that no further bat surveys are required, allowing the planning application to proceed.
Can a PRA be completed at any time of year?
Yes. As a daytime inspection, a Preliminary Roost Assessment can be undertaken throughout the year. However, any recommended follow up surveys may be seasonally constrained.
How long does a Shropshire PRA typically take on site?
The duration depends on the size and complexity of the building. Small residential properties may take around an hour, while larger barns or farm buildings may require more time.
Will a PRA delay my rural development project?
Undertaking a PRA early in the planning process helps prevent delays. Submitting the required ecological information with the initial application reduces the likelihood of additional planning conditions.
