Do you Need a Preliminary Roost Assessment (PRA) in Leicestershire?
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. Leicestershire 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 Leicestershire, PRAs are commonly required where development interfaces with:
• Victorian, Edwardian and interwar stock in Leicester, Loughborough and Hinckley
• Agricultural conversions and barn reuse across Harborough, Melton and Blaby
• Regeneration land and mill buildings in Coalville and Syston
• Watercourses, woodland edges and hedgerow linkages tied to the Soar Valley
Validation frequently hinges on PRA evidence where potential roosts are implicated.
Our Bat Dusk Emergence Survey services operate across Leicestershire, supporting developments in city, town and rural settings countywide.
Why Leicestershire Planning Authorities Request Preliminary Roost Assessments
Leicestershire 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 Leicestershire 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 Leicestershire 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 Leicestershire Projects
Where bat scoping is required to unlock planning in Leicestershire, 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 Leicestershire
What is a Preliminary Roost Assessment in Leicestershire?
A Preliminary Roost Assessment is a daytime bat survey carried out by a qualified ecologist to determine whether a building has potential to support roosting bats. It is commonly required to support planning applications involving roof alteration, demolition or conversion.
Do Leicestershire councils require a PRA for planning applications?
Often yes where building works could affect roof spaces, loft voids or structural gaps. Local Planning Authorities may request a PRA at validation or as a condition before works start.
Planning guidance for Leicester City Council can be accessed at:
https://www.leicester.gov.uk/planning-and-building/
Are rural properties near Charnwood Forest more likely to require bat surveys?
Often yes. Properties close to Charnwood Forest and surrounding countryside frequently sit within bat foraging and commuting landscapes, increasing the likelihood that roof and outbuilding works require assessment.
Do roof refurbishments in Leicestershire market towns need a bat survey?
They can. Works to older pitched roofs, loft conversions and dormers may affect bat access points and commonly trigger the need for a Preliminary Roost Assessment.
Can installing roof insulation or replacing soffits and fascias require a PRA?
It can. Works to eaves, soffits, fascias and roofline gaps can affect potential bat access points. A PRA may be required where these elements are altered as part of a wider refurbishment.
Is a PRA required for demolition of detached garages or small outbuildings?
Often yes where structures include roof voids, gaps or exposed rafters. Outbuildings are regularly assessed in addition to the main property.
Do replacement agricultural buildings require a Preliminary Roost Assessment?
They can. Demolition and replacement of farm buildings may require bat survey information where the existing structure has roost potential.
Can a Preliminary Roost Assessment be carried out at any time of year?
Yes. A PRA is a daytime inspection and can be undertaken year round. If moderate or high roost potential is identified, further surveys may be seasonally restricted.
What happens if the PRA identifies moderate bat roost potential?
If moderate potential is recorded, dusk emergence or dawn re entry surveys may be recommended before works proceed, to confirm whether bats are present.
