This document sets out broadly what is involved when a ‘bat survey and report’ is required in relation to small-scale development (householder planning applications) in the UK. This guidance may be provided to homeowners by those commissioned to undertake surveys, in order to provide some background to bat surveys and assessment. This document is not a guide to undertaking bat surveys. Further advice about bats is available from the Bat Conservation Trust or through the National Bat Help Line (0345 1300 228).
