Do you Need a Preliminary Roost Assessment (PRA) in Nottinghamshire?
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. Nottinghamshire 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 Nottinghamshire, Preliminary Roost Assessments are most frequently requested where development engages with:
• Victorian and interwar housing across Nottingham, Beeston, Arnold and Mansfield where pitched roofs, soffits and voids create roosting niches
• Farmstead conversions across Rushcliffe, Bassetlaw and Gedling involving brick barns, steel sheds and stone outbuildings
• Regeneration and infill sites in Newark, Worksop and Hucknall where legacy structures are retained within proposals
• River corridors, woodland belts and hedgerow networks linked to the Trent Valley and its tributaries
PRA scope is routinely queried at validation wherever bat roost suitability is identified.
Our Bat Dusk Emergence Survey services operate across all of Nottinghamshire, from city locations and industrial corridors to village edges and wider rural environments.
Why Nottinghamshire Planning Authorities Request Preliminary Roost Assessments
Nottinghamshire 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 Nottinghamshire project involves demolition, conversion or structural alteration, PRA evidence should be confirmed before the application reaches validation.

Key Deliverables for Nottinghamshire Projects
Where bat scoping is required to unlock planning in Nottinghamshire, 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 Nottinghamshire
What is a Preliminary Roost Assessment in Nottinghamshire?
A Preliminary Roost Assessment is an initial bat survey undertaken by a qualified ecologist to determine whether a building or structure has the potential to support roosting bats. It is commonly required to support planning applications where roof works, demolition or structural alterations are proposed.
When do Nottinghamshire councils request a PRA?
Local Planning Authorities such as Rushcliffe Borough Council, Gedling Borough Council and Bassetlaw District Council typically require a PRA where development could affect roof spaces, outbuildings, barns or mature trees.
Planning validation guidance for Rushcliffe Borough Council can be accessed at:
https://www.rushcliffe.gov.uk/planning/
Is a PRA required for house extensions in Nottinghamshire?
It may be required if the extension affects the roof, gable ends, soffits or existing roof void. Even small residential schemes can trigger the need for a bat survey if suitable roosting features are present.
Can a PRA be carried out at any time of year?
Yes. A Preliminary Roost Assessment is a daytime inspection and can be undertaken year round. However, if bat evidence is identified, follow up surveys may need to take place during the active bat season.
Does a PRA involve climbing onto the roof?
External inspections are normally undertaken from ground level using ladders or specialist equipment where safe and necessary. The survey focuses on identifying features such as lifted tiles, gaps and access points.
Are older brick properties in Nottinghamshire more likely to require a PRA?
Older properties, especially Victorian or pre 20th century buildings, often contain gaps and crevices that may provide bat roost potential. These buildings are more likely to trigger ecological survey requirements.
What happens if the building has moderate or high bat roost potential?
If the assessment identifies moderate or high roost potential, additional surveys such as dusk emergence or dawn re entry surveys may be required to confirm bat presence.
How long does a PRA report take to prepare?
Following the site visit, the written report is typically issued within a short timeframe, depending on workload and project complexity. The report outlines findings and any recommendations.
Will a PRA delay my planning application?
Undertaking a PRA early in the design stage reduces the risk of delay. Submitting ecological information upfront avoids planning conditions being imposed later in the process.
