Do I Need a Bat Survey for Planning in Preston City?
Planning authorities may request bat surveys where development proposals could affect buildings, trees or habitats capable of supporting bats.
While every site is different, surveys are often requested where development involves features that may provide roost opportunities or where habitats used by bats could be disturbed.
You may need a survey if your project involves:
- Roof alterations, loft conversions or structural roof repairs
- Demolition of buildings or redevelopment of existing structures
- Barn conversions or redevelopment of agricultural buildings
- Removal of mature trees with cavities or loose bark
- Development near rivers, woodland edges or green corridors
- Installation of external lighting affecting bat flight paths
- Development located within or close to ecologically sensitive areas
Even relatively small developments may require ecological survey information if there is potential for bats to be present. Surveys help planning authorities assess whether development proposals could affect protected species and whether mitigation measures may be required.
Bat Survey Process Explained
Bat surveys usually follow a structured assessment pathway designed to determine whether bats are present and whether development could affect them. This staged approach helps ensure planning authorities receive reliable ecological evidence when assessing development proposals and considering potential impacts on protected species.
The process generally follows three stages:
- Preliminary assessment
- Activity surveys (if required)
- Mitigation or licensing support where necessary
This structured approach helps ecologists evaluate buildings, trees and surrounding habitats while providing planning authorities with clear ecological evidence to inform planning decisions. Surveys also help identify potential bat roosting sites, bat activity patterns and habitats that may support bats within the wider landscape.
By following this staged process, ecologists can determine whether further surveys are necessary and provide recommendations that help ensure development proposals consider wildlife conservation and relevant planning requirements.
Preliminary Roost Assessment Preston City
A preliminary roost assessment Preston City is typically the first stage of the bat survey process. This daytime inspection involves an ecologist visiting the site to assess buildings or trees for features capable of supporting bats.
During this survey, ecologists will:
- Inspect buildings internally and externally
- Examine roof voids and structural elements
- Identify potential bat access points such as gaps or lifted tiles
- Assess surrounding habitat that may support bat activity
- Evaluate potential bat roosting sites
The survey also considers surrounding habitat features such as hedgerows, woodland edges and watercourses that may support bats commuting or feeding near the development site. These habitats can influence bat presence because they provide insects and flight corridors used by bats moving between roosts and feeding areas.
The outcome of the assessment determines whether the building or tree has negligible, low, moderate or high bat roost potential, which helps establish whether further activity surveys may be required.
Bat Emergence and Re-entry Surveys
If the preliminary assessment identifies bat roost potential, activity surveys may be required. A bat emergence survey Preston City involves dusk monitoring where ecologists observe a building or structure to record bats leaving a roost. Re-entry surveys occur at dawn when bats return to the roost.
These surveys help determine whether bats are present and identify the species using the structure.
During activity surveys:
- Ecologists monitor buildings during dusk or dawn periods
- Acoustic detectors record ultrasonic bat calls
- Species identification techniques help determine which bat species are present
- Flight paths and roost locations are recorded
The results help determine whether bats are present and whether development proposals could affect a roost.
Reporting and Planning Submission
Following bat surveys in Preston City, ACP Consultants provides a clear, planning-ready ecological report suitable for submission with planning applications. The report supports homeowners, architects, planning consultants, developers and project teams. It is suitable where bat survey evidence is required by Preston City Council or ecological consultees.
The report summarises survey methods, site context, findings, bat roost potential and bat activity where recorded. It also provides recommendations for mitigation or further surveys where required. The report explains whether buildings, trees, roof spaces, access points, surrounding habitats or nearby ecological features could support bats. It also explains whether they could be affected by the proposed development.
This helps planning officers, ecological consultees, architects and project teams understand whether development could affect bats or their habitats. When no evidence of bats is found, the report can provide useful ecological evidence to support the planning submission. If bat roost potential or bat activity is identified, the report sets out proportionate recommendations. It also provides clear next steps.
Where needed, the report outlines the next steps. These include bat emergence survey requirements, timing considerations, licensing advice and measures to support planning compliance. This may include advice on survey season, avoidance measures, sensitive lighting, habitat protection, roost mitigation or further ecological input before works proceed.
Mitigation, Licensing and Planning Support
Where bats are confirmed during survey work, ecologists may recommend mitigation measures to ensure development does not negatively affect protected species and complies with relevant legislation. Mitigation measures can include:
- Timing of works to avoid disturbance
- Retention of roost features where possible
- Installation of bat boxes or alternative roosting habitat
Mitigation strategies are designed based on survey findings and site conditions, ensuring impacts are avoided or reduced where possible and aligned with recognised ecological guidance. In some cases, a protected species licence may be required before works proceed, particularly where roosts could be affected. These measures help support habitat preservation, maintain bat populations and allow development works to proceed while maintaining appropriate ecological safeguards and compliance with planning requirements, supporting sustainable development outcomes.
Bat Survey Season and Planning Timelines
Bat surveys are influenced by the seasonal behaviour of bats. This makes survey timing important for planning applications. Different survey types can be undertaken at different times of year. Timing depends on the survey purpose and the bat roost potential identified during the initial assessment.
Activity surveys are typically undertaken between May and September. During this period, bats are active and detectable using acoustic monitoring equipment. Licensed ecologists can observe bats emerging from roosts or returning to roosts. They can also record bat activity using recognised survey methods. The number of survey visits required depends on the site’s bat roost potential. It will also reflect current ecological guidance.
Outside this period, bats may be hibernating or inactive. This means activity surveys cannot usually be carried out effectively. However, daytime inspections, such as a Preliminary Roost Assessment (PRA), can often be undertaken throughout the year. These inspections assess buildings or trees for features that could support bats. They also determine whether further seasonal surveys are necessary.
Because of these seasonal constraints, ecological surveys should ideally be considered early in the planning process. Early surveys help ensure planning applications are not delayed by seasonal survey requirements. They also provide sufficient time to complete any necessary follow-up surveys. This allows ecological recommendations to be incorporated into project design and planning submissions.
Costs and Timescales
Bat survey costs vary depending on the size and complexity of the development site. Every project is different, so the scope of work will depend on factors such as the type of development, the characteristics of the site, and whether further ecological surveys are required following the initial assessment.
Key factors influencing survey costs include:
- The number of buildings or trees requiring inspection
- Site size and surrounding habitat context
- Whether additional activity surveys are required
- Accessibility of roof spaces or structures
- The level of bat roost potential identified during the preliminary assessment
- Seasonal survey requirements and the number of survey visits needed
Preliminary roost assessments are usually completed within a single site visit, while activity surveys may require multiple evening or dawn visits. Survey timescales can also vary depending on seasonal survey windows, weather conditions suitable for bat activity surveys, and the complexity of the site.
Obtaining ecological advice early in the planning process can help avoid unnecessary delays where seasonal surveys are required. Following an initial assessment, ACP Consultants can provide a clear quotation, explain the recommended survey approach, outline expected timescales, and advise whether a Preliminary Roost Assessment, bat emergence survey or additional ecological work is likely to be required to support your planning application.
Local Planning and Policy Context
Planning authorities in England are required to consider biodiversity when assessing development proposals. In Preston City Council areas, ecological considerations are typically addressed through local planning policy and national planning guidance that requires development proposals to consider impacts on protected species and biodiversity.
Planning policies relating to biodiversity often encourage development proposals to:
- Protect habitats that support wildlife
- Avoid harm to protected species where possible
- Mitigate ecological impacts where development affects habitats
- Enhance biodiversity through habitat management or design
Where bats may be present, ecological surveys help planning officers determine whether development proposals comply with biodiversity policy requirements.
Bat surveys therefore form an important part of ecological assessment within the planning system.
Local Bat Ecology and Development Context in Preston
Preston contains a diverse mix of historic urban buildings, suburban housing estates and surrounding rural landscapes. Older properties within the city often contain traditional roof structures with timber beams and slate tiles, which can occasionally provide suitable roosting opportunities for bats.
Buildings constructed before modern roofing materials were widely used may contain small access points or crevices where bats can roost. Because of this, redevelopment of older housing stock can sometimes trigger the need for ecological assessment.
The River Ribble corridor forms an important ecological feature within the Preston landscape. Rivers and watercourses often support large insect populations, which provide feeding opportunities for bats during the evening.
Green infrastructure across the city, including parks, woodland edges and tree-lined corridors, can also support bat commuting routes. Bats frequently use hedgerows and tree lines as navigation features while travelling between roosts and feeding habitats.
Across Lancashire, bats rely on networks of feeding habitats and roost structures. Ecologists therefore consider the wider landscape context when assessing development proposals, including how development may affect local feeding routes or commuting corridors.
Understanding these ecological relationships allows ecologists to develop appropriate habitat management strategies that support wildlife conservation efforts while allowing development to proceed responsibly.
What you Receive
Following completion of a bat survey, clients receive a comprehensive ecological report suitable for submission with planning applications. The report is prepared in a clear, structured format so it can be reviewed efficiently by planning officers, ecological consultees, architects and project teams involved in development proposals.
Reports typically include:
- Description of the site and surrounding habitats – outlining the property location, building type and landscape context, including nearby woodland edges, rivers, parks or farmland that may influence bat activity.
- Findings from the ecological assessment – summarising survey observations and habitat features relevant to bats.
- Evaluation of bat roost potential – identifying structural features within buildings or trees that may support bats and explaining the assessed level of roost potential.
- Identification of bat activity where relevant – summarising survey observations and any evidence of bat presence.
- Recommendations for mitigation where necessary – outlining proportionate measures to protect bats if development could affect a roost or habitat.
- Advice on next steps for planning submissions – explaining whether additional surveys or ecological input may be required.
Reports may also include ecological analysis such as habitat suitability modelling where appropriate. These reports help planning authorities understand the ecological context of development proposals.

Common Project Types in this Area
Bat surveys may be required for a wide range of development projects across the Preston area, particularly where works could affect buildings, roof spaces, trees or habitats that may support bats. In planning terms, survey requirements are usually linked to the likelihood of bats being present and whether the proposed works could disturb, damage or remove a roost.
Common project types include residential redevelopment of older buildings, barn conversions in rural Lancashire locations, roof repairs, structural alterations or loft conversions. Bat surveys may also be required for demolition or redevelopment of commercial properties, tree removal associated with development, and housing developments near woodland or river corridors.
In Preston, projects involving older housing stock, traditional roof structures, agricultural buildings, mature trees, parks, hedgerows or land close to the River Ribble corridor may need ecological assessment before planning decisions can be made. These local features can provide suitable roosting, foraging or commuting habitat for bats, especially where development could introduce lighting, vegetation loss or changes to existing structures.
Where development proposals involve buildings or habitats capable of supporting bats, ecological surveys may be requested during the planning process. A bat survey helps establish whether bats are likely to be affected and provides planning officers, architects, developers and project teams with clear recommendations for next steps.
