Do I Need a Bat Survey for Planning in West Lancashire District?
A bat survey may be required where development proposals could affect potential bat roosting sites within buildings, structures or trees. Because bats are protected species in England, planning authorities must consider whether development could impact bats before determining planning applications.
Planning authorities do not request surveys automatically for every project. Instead, surveys are usually required where there is a reasonable likelihood that bats could be present or where buildings and habitats contain features capable of supporting roosts.
Common triggers include:
- Demolition of existing buildings
- Roof alterations or loft conversions
- Barn conversions and redevelopment of agricultural buildings
- Removal of mature trees or woodland edge habitats
- External lighting proposals affecting dark corridors used by bats
- Development near ponds, rivers or wetland habitats
- Redevelopment of older properties with complex roof structures
Older buildings can contain small gaps or voids that provide shelter for bats, particularly in roof spaces or beneath tiles. Similarly, mature trees may contain cavities, splits or loose bark capable of supporting roosts.
If such features are present, planning officers may request a protected species survey to determine whether bats could be affected by development proposals and whether further ecological assessment is required.
Bat Survey Process Explained
Bat surveys typically follow a structured process used across England. This staged approach keeps surveys proportionate to the ecological risk of each site. It also provides planning authorities with appropriate ecological evidence.
The survey pathway normally begins with an initial inspection, known as a preliminary roost assessment. This checks buildings, trees and surrounding habitats for features capable of supporting bats. Examples include roof voids, gaps beneath tiles, crevices, mature trees, hedgerows or nearby watercourses.
Where no suitable features are identified, further survey work may not be required. Where features capable of supporting bats are found, the process may progress to further activity surveys. These may include bat emergence or re-entry surveys during the active survey season.
This process helps determine whether bats could be present. It also assesses whether development proposals could affect potential roosting locations or habitats used by bats. The findings help establish whether mitigation, timing advice or further ecological input may be needed before works proceed.
By following this staged pathway, applicants can avoid unnecessary survey work. They can still provide planning authorities with clear evidence for decision-making and protected species compliance.
Preliminary Roost Assessment (PRA)
A preliminary roost assessment West Lancashire District is normally the first stage of a bat survey. During this daytime inspection, a qualified ecologist examines buildings or trees for features that could support bat roosts. The survey involves both internal and external inspection where access is available.
The ecologist will look for indicators such as:
- Gaps beneath roof tiles or ridge lines
- Access points in soffits or roof junctions
- Crevices within brickwork or stonework
- Roof voids that provide dark, sheltered spaces
- Tree cavities or lifted bark
The surrounding landscape is also assessed to understand habitat suitability. Features such as hedgerows, ponds and woodland edges can provide important feeding habitats for bats and may influence whether further surveys are required. If no suitable roosting features are present, further surveys may not be required.
Bat Emergence Survey
Where potential roost features are identified, bat emergence survey West Lancashire District activity surveys may be recommended. These surveys confirm whether bats are using the building, structure or tree.
Ecologists observe buildings or structures at dusk to record bats emerging from roost sites. In some cases, surveys may take place before sunrise. This allows ecologists to observe bats returning to roosts. These observations help establish whether a roost is present. They also show how bats are using the site.
Acoustic bat detectors are used to record ultrasonic calls produced by bats. These recordings help ecologists identify species and understand activity levels around the site. This may include commuting and foraging behaviour near hedgerows, woodland edges, gardens or watercourses.
Multiple surveys may be required depending on habitat suitability and survey guidance. The number of visits can depend on the level of roost potential. It can also depend on the type of development proposed. The features being assessed may also influence survey requirements.
Findings from BERS surveys help inform planning decisions, mitigation advice and further ecological steps before works proceed.
Reporting and Planning Submission
Following completion of bat surveys in West Lancashire District, ACP Consultants prepares a clear, planning-ready ecological report suitable for submission with a planning application or discharge of planning conditions. The report is structured so planning officers, ecological consultees, architects and project teams can efficiently review the ecological evidence alongside the proposed development.
The report sets out survey methods, findings, potential bat roosting sites, species observations where recorded, and any recommendations for mitigation or further survey work. It also explains the level of bat roost potential identified, whether additional surveys such as bat emergence surveys are required, and the next steps needed to support the planning process.
Where bats are recorded, the report provides proportionate recommendations to help minimise potential impacts and ensure development proposals consider protected species appropriately. Where no evidence of bats is found, the report provides valuable ecological evidence to support the planning submission.
Reports are prepared in accordance with recognised ecological guidance and provide clear, objective findings to support informed planning decisions. While ecological reports can help planning authorities assess biodiversity considerations, they support informed planning decisions without guaranteeing approval.
Mitigation, Licensing and Planning Support
If a bat roost is confirmed during surveys, development proposals may require mitigation measures to avoid or reduce impacts on bats and their roosts. The type of mitigation recommended will depend on the species present, the importance of the roost and the nature of the proposed works.
Mitigation strategies could include:
- Retention of roost features where feasible
- Installation of bat boxes or roosting features
- Timing restrictions on construction works
- Design adjustments to reduce lighting impacts
Where development could affect a bat roost, a European Protected Species licence may sometimes be required before works begin. Licensing requirements are considered on a site-by-site basis and depend on the survey findings and the potential impacts of the proposed development.
Ecologists can provide advice and documentation to support planning authorities and licensing applications where appropriate. This may include preparing mitigation strategies, advising on suitable ecological enhancements and helping ensure recommended measures are incorporated into the development design. By considering mitigation early in the planning process, developers can better understand ecological constraints, support protected species conservation and provide planning authorities with the information needed to make informed planning decisions.
Bat Survey Season and Planning Timelines
Some bat surveys are seasonal because bats are only active during certain months. Most activity surveys are undertaken between May and September, when bats are active and detectable at dusk and dawn. During colder months bats typically hibernate and may not emerge from roosts, making activity surveys unreliable.
However, a preliminary roost assessment can usually be undertaken at any time of year because it focuses on identifying potential roosting features rather than recording bat activity. This makes it a useful first step for early planning, especially where development involves roof works, demolition, barn conversion, tree removal or lighting changes.
Because activity surveys are seasonal, early planning is important. Development proposals submitted without ecological evidence may experience delays if surveys are requested during the planning process, particularly outside the main bat survey season.
Booking surveys early helps ensure survey requirements can be completed within appropriate seasonal windows. It also gives applicants time to arrange any required follow-up surveys, mitigation advice or reporting before planning deadlines. Early ecological input can help reduce avoidable delays and support a smoother planning submission.
Costs and Timescales
The cost of a bat survey varies depending on the scale and complexity of the project. Every site is different, so survey requirements are based on the type of development proposed, the characteristics of the buildings or trees being assessed and the likelihood of bats being present.
Factors that influence survey costs include:
- Number of buildings or structures involved
- Habitat suitability and ecological complexity
- Requirement for additional activity surveys
- Seasonal timing of surveys
A preliminary roost assessment is usually the first stage and can often be arranged quickly. If the initial inspection identifies features capable of supporting bats, additional bat activity surveys may be recommended.
Where bat activity surveys are required, multiple visits may be necessary during the bat activity season, in accordance with recognised ecological guidance. The overall programme can therefore vary depending on survey timing, weather conditions and the number of survey visits needed.
Because every site is different, the best approach is to request a tailored quotation based on your project details. Obtaining ecological advice early in the planning process can help identify survey requirements, avoid seasonal delays and ensure sufficient time is available to complete surveys before submitting a planning application.
Local Planning and Policy Context
Planning policy across England requires decision-makers to consider potential impacts on biodiversity when determining planning applications.
Local authorities such as West Lancashire District Council typically require ecological evidence where development proposals may affect protected species or habitats.
Planning submissions may therefore require:
- Protected species surveys where suitable habitats are present
- Ecological assessments linked to development proposals
- Consideration of biodiversity enhancement measures
Some development proposals may also be associated with wider environmental requirements, such as environmental impact assessment or biodiversity net gain.
Providing ecological survey evidence early in the planning process helps planning authorities understand potential environmental impacts and assess applications efficiently.
Local Context: Development and Bat Habitat
West Lancashire District contains a varied landscape that provides suitable habitats for several bat species. Much of the district is characterised by agricultural land, hedgerows and rural settlements, creating corridors that bats use for feeding and commuting.
The River Douglas and associated drainage channels provide linear habitats that bats often follow while travelling between roost sites and feeding areas. Water bodies can attract insects, which are a key food source for bats.
Woodland edges and farmland hedgerows across the district also create sheltered flight paths. These features allow bats to move through the landscape while avoiding open areas where they may be more exposed to predators.
Settlements such as Ormskirk, Burscough and Rufford contain older buildings and historic farm structures that can provide roosting opportunities. Agricultural barns and traditional brick buildings may contain roof voids, crevices and gaps that bats can use for shelter.
Even within more urbanised areas such as Skelmersdale, green corridors, parks and woodland edges can support bat populations.

Common Project Types in this Area
Projects frequently requiring bat surveys for planning West Lancashire District include barn conversions, redevelopment of older buildings and residential extensions affecting roof structures. These works can disturb roof voids, loft spaces, wall crevices or other areas where bats may roost.
Agricultural buildings across rural parts of Lancashire can often contain features suitable for bats, meaning surveys are sometimes requested before conversion or demolition works proceed. This is especially relevant where barns, stables or outbuildings are close to hedgerows, ponds, woodland edges or farmland used by bats for commuting and foraging.
Tree removal associated with development sites can also trigger ecological assessment where mature trees contain cavities, splits, lifted bark or other potential roosting features. External lighting schemes may also require consideration where they affect dark corridors used by bats.
In addition, infrastructure proposals and larger development sites may require ecological surveys as part of broader environmental assessments. Early bat survey advice helps identify whether a preliminary roost assessment, bat emergence survey or mitigation measures are needed before planning submission.
