Do you Need a Preliminary Roost Assessment (PRA) in London?

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. London 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 Greater London, PRAs are principally required where proposals affect:

• Pre-1940 housing, mansion blocks and converted stock across outer London boroughs

• Commercial to residential reuse in Opportunity Areas with retained roof structures

• Estate regeneration and retrofit programmes impacting soffits, voids and pitched roofs

• Waterways, railway cuttings and treed corridors aligned with the Thames Basin network

Where roost potential is moderate or above, PRAs are commonly mandated at validation.

Our Bat Dusk Emergence Survey services are provided across every London borough, supporting inner-city sites, suburban locations and the capital’s network of parks and green corridors.

Why London Planning Authorities Request Preliminary Roost Assessments

London 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 London project involves demolition, conversion or structural alteration, PRA evidence should be confirmed before the application reaches validation.

Local Case Insight

A refurbishment to a semi-rural edge property in outer London near green belt interfaces required roof reconstruction. Screening identified ventilation gaps and lifted tiles. The PRA verified no evidence of roosting and confirmed low risk. The London planning authority validated the application on submission, preventing seasonal survey constraints from slowing the programme. Embedded design mitigation allowed progression without licence requirement.

Do you Need a Bat Dusk Emergence Survey in Nottinghamshire?

If you’re a homeowner in Nottinghamshire, a dusk emergence survey is typically required when roof works, loft conversions, barn conversions or demolition affect buildings with potential bat roost features. Nottinghamshire councils will usually seek confirmation that bats are not using the structure before works proceed. 

For developers in Nottinghamshire, dusk emergence surveys are required where a Preliminary Roost Assessment (PRA) identifies low, moderate or high roost potential and planners need robust presence/absence evidence to validate the application. This commonly affects housing schemes, conversions, infrastructure upgrades and regeneration sites. 

Early confirmation protects your programme from seasonal delay, redesign and unexpected licensing. 

Across Nottinghamshire, dusk emergence surveys are frequently required where development interacts with:

• Victorian and interwar housing across Nottingham, Beeston and Arnold where roof voids, tile gaps and soffit gaps indicate ingress points

• Agricultural conversions across Rushcliffe, Bassetlaw and Gedling involving barn and traditional outbuilding reuse

• Regeneration and infill land in Newark, Mansfield and Worksop where retained structures interface with new layouts

• River corridors, canals and wooded edges associated with the Trent Valley and tributary networks

Bat survey requirements are commonly scrutinised at validation where credible roost potential is recorded on site.

Our Bat Dusk Emergence Survey services operate throughout Nottinghamshire, supporting sites across busy urban areas, industrial zones, market towns and countryside settings.

Why Nottinghamshire Planning Authorities Request Bat Dusk Emergence Surveys

Nottinghamshire planning authorities require dusk emergence survey evidence wherever buildings or trees present 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 seasonal emergence data, planners cannot lawfully confirm that development will avoid disturbance to protected roosts. 

If your Nottinghamshire project involves demolition, conversion or structural alteration, bat emergence evidence should be confirmed before your application reaches validation. 

Local Case Insight

A residential conversion in rural Nottinghamshire proposed the redevelopment of a former farm outbuilding positioned among hedgerows and drainage ditches. An initial inspection identified potential bat access within lifted tiles and an unlined roof void. Two dusk emergence surveys were undertaken in suitable early-summer conditions, confirming bat activity along adjacent treelines but no use of the structure itself. The report supported LPA validation without seasonal conditions, and modest lighting and boundary provisions were added to the design. Works moved into construction without the need for a licence.

FAQ - Bat Dusk Emergence Surveys in Nottinghamshire

What is a bat emergence survey for planning in Nottinghamshire?

A bat emergence survey is an evening or early morning survey used to confirm whether bats are roosting within a building. Ecologists observe the structure at dusk or dawn to record bats leaving or returning to potential roost locations.

Speak to Our Team

Emergence surveys are typically required where a Preliminary Roost Assessment identifies moderate or high bat roost potential. Local Planning Authorities require this survey evidence to confirm whether bats are present before determining a planning application.

Planning guidance for Nottingham City Council can be accessed at:
https://www.nottinghamcity.gov.uk/planning-and-building-control/

Check My Site

Bat emergence surveys must be carried out during the bat active season, generally between May and September. Surveys outside this period are not considered reliable for planning decisions.

Survey requirements depend on the level of bat roost potential identified. Moderate potential usually requires two surveys, while high potential normally requires three survey visits during the season.

Ecologists observe the building at dusk or dawn and use specialist bat detectors to record echolocation calls. This allows surveyors to identify bat species and confirm whether bats are using the structure as a roost.

Are emergence surveys needed for residential roof redevelopment?

They can be. If roof works affect loft spaces, tiles, soffits or other potential bat access points, emergence surveys may be required following the initial roost assessment.

Secure Survey

No. Surveys cannot be undertaken during heavy rain, strong winds or low temperatures, as these conditions significantly reduce bat activity and affect survey reliability.

Request Survey Quote

Each individual survey visit lasts approximately two to three hours around sunset or sunrise. However, completing all required survey visits may take several weeks depending on weather and scheduling.

If a bat roost is confirmed, the development may need to incorporate mitigation measures. This ensures that works can proceed while complying with wildlife protection legislation.

ProHort undertakes professional bat emergence surveys across Nottinghamshire. Our experienced ecologists design survey programmes that meet national guidance and local planning authority requirements, helping projects progress with minimal delay.

Local Case Insight

In Sussex, a barn-to-residential conversion near woodland margins and historic hedgerow boundaries required bat assessment prior to planning. Preliminary checks found crevice features beneath weathered tiles with limited internal voids. Two dusk emergence surveys during optimal summer weather recorded foraging bats in nearby treelines but none emerging from the building. The council validated the application with no additional seasonal restrictions; targeted lighting controls and boundary enhancement were incorporated. Construction proceeded without licensing delay.

Speak to Our Team

Bat emergence surveys are normally required where a Preliminary Roost Assessment identifies moderate or high roost potential within a building. Planning authorities use the results to determine whether bats are present before granting permission for development.

Planning guidance for Brighton & Hove City Council can be accessed at:
https://www.brighton-hove.gov.uk/planning

Check My Site

Yes. Properties near the coast or along the South Downs often sit within active bat foraging corridors. Roof alterations or redevelopment proposals may require seasonal bat surveys to confirm whether roosts are present.

They can be. Historic buildings often contain roof voids, timber beams and structural features that provide potential roosting locations for bats.

Bats are identified using ultrasonic bat detectors which record echolocation calls. These recordings allow ecologists to determine the species using the building and assess the importance of the roost.

What happens if bats are seen emerging from a building?

If bats are observed leaving the building, the survey will confirm that a roost is present. The planning authority will then review the development proposal to determine whether mitigation measures are required.

Secure Survey

Yes. Multiple survey visits are normally required during the bat activity season to provide reliable evidence of bat presence or absence.

Request Survey Quote

They can. Even modest projects such as loft conversions or roof alterations may require bat surveys where potential roost features are present.

The planning authority may request additional ecological information or delay determination of the application until the surveys have been completed.

They can be. Older terraced properties often contain roof voids, tile gaps and ridge features that can support bat roosts. Surveys may be required where works affect these areas.

Yes. Offices, warehouses and former industrial buildings may contain roof spaces or structural cavities that could support bats. Surveys confirm whether roosts are present before redevelopment proceeds.

They can. Even on urban brownfield sites, existing buildings may provide potential roost features and require emergence surveys before demolition or refurbishment.

What do ecologists record during a bat emergence survey?

Surveyors record bat activity around the building, including emergence locations, flight paths and species present. This information helps determine whether the structure supports a roost.

Secure Survey

Yes. Surveys are carefully timed around sunset or sunrise because artificial lighting and darkness levels can influence bat activity and observation conditions.

They can be. Refurbishment projects involving roof works, structural alterations or building extensions may require surveys where bat roost features are present.

Yes. Roof plant areas, service voids and cladding gaps can create sheltered spaces that may be used by bats, meaning surveys may be required before alterations take place.

In some cases they are. Upgrading or refurbishing office buildings may affect roof spaces or structural elements that could support bat roosts.

How do ecologists monitor bats in built up areas?

Surveyors position themselves around the building to observe potential roost access points while using bat detectors to record echolocation calls and confirm bat activity.

Secure Survey

Yes. Even relatively small structures such as retail units or commercial premises may contain features that provide potential bat roosting opportunities.
