Bats and their roosts are fully protected by British and European law. The law applies whether the bats are present at the roost or not. Anyone who is involved in activities that may impact on bats has a legal responsibility to comply with the law. You are therefore strongly advised to acquaint yourself with the law protecting bats.

Where there is a possibility that bats may be impacted by development proposals, planning authorities are required to ask for bat surveys to be undertaken prior to determining a planning application. You are strongly advised to discuss your proposals with the planning authority before submission of an application.
