In the UK, there are 18 species of bats, which commonly roost in trees, caves, buildings, and other structures. All bat species and their roosts are fully protected under UK wildlife law. Bat surveys are frequently required during the planning process to identify the presence of bat roosts and understand how bats use a site for foraging and commuting.

The process typically begins with a Preliminary Bat Roost Assessment (PRA), where a building or tree is evaluated for its potential to support bats. If required, this is followed by bat roost (emergence) surveys to confirm the presence or likely absence of bats, which is often essential for securing planning permission.

At Noctua Ecology, our bat projects are conducted by a team of experienced ecologists with a shared passion for bats. With advanced licences for bat surveys, including Natural England Bat Survey Licence Levels 1, 2, 3, and 4, as well as accreditation under the Bat Earned Recognition (BER) scheme, our ecologists ensure expert oversight on every project.

We offer a comprehensive range of bat-related services, including:

• Preliminary Bat Roost Assessment (PRA)

• Bat roost (emergence) survey

• Bat activity survey

• Tree climbing bat survey

• Bat mitigation licensing

• Bat Earned Recognition (BER) licensing

• Harp trapping and mist netting

• Radio tracking

Our expertise ensures that your project complies with wildlife law while maintaining a balance between development and bat conservation.
