I Need a Bat Survey

If you have been asked to undertake a bat survey by your local planning authority this page should help you to understand the process.

Why have I been asked to undertake a bat survey?bat survey

In Britain all bat species and their roosts are legally protected, by both domestic and international legislation. It is an offence to:

  • Deliberately capture, injure or kill a bat
  • Intentionally or recklessly disturb a bat in its roost or deliberately disturb a group of bats
  • Damage or destroy a bat roosting place (even if bats are not occupying the roost at the time)
  • Intentionally or recklessly obstruct access to a bat roost

When considering the approval of your development proposals the local planning authority and licensing agencies require information  to determine the effects of the development on bats, to identify which species, if any, are present and to identify if mitigation, compensation or enhancement measures are required.

Habitat Regulations licence

If bats are found during the survey it is likely that a Habitats Regulations licence will be required before works can commence. In Wales, these licences are issued by Natural Resources Wales. The licence application will need to be accompanied by a detailed method statement which sets out the activities to be carried out and ensures that bats will not be harmed during construction works. The method statement must ensure that provision is made for new roosting opportunities after the completion of development works.

Can bats stop a development?

It is very unlikely that bats will stop a development, although measures may need be incorporated into the development to allow bats to continue using the site after the completion of development works.

What time of year can a survey be undertaken?

The timing of bat surveys is very important. A scoping survey or preliminary roost inspection can be undertaken throughout the year to assess the potential of a building/structure being used by bats. However, if the survey determines that the structure has potential to be used by bats, dawn and dusk surveys will need to be undertaken during the active season (late April – September). Conversely, if a building is assessed as potentially being used as hibernation site a winter survey may be required.

How Acer Ecology Can Help You

Our licensed bat survey specialists are experienced in survey, European Protected Species licensing and mitigation design and implementation.

We can assist you by undertaking an initial scoping survey to assess the potential for bats to be present on your site. Expert advice will be provided  on the options and solutions available. If a European Protected Species licence is required we can complete and submit your licence application.  Upon approval of the licence we can provide continuing assistance to help you ensure that the terms of the licence are adhered to.
