There are 18 species of Bats in the UK (though only 17 known to be breeding here), all of which are protected by European and UK Law and are consequentially a material consideration in the planning process.
Due to their variable activity patterns and hibernation over the late autumn and winter period, surveys to determine the presence (or likely absence) of summer roosts of bats are best carried out in the optimum period between May & August when bats are at their most active; though surveys can be carried out between April and September if weather conditions are good. Please refer to our Ecology Survey Calendar for further information
Preliminary Roost Assessments (PRA)
Wharton offer Preliminary Roost Assessments (also known as initial bat surveys) which are regularly requested by Local Planning Authorities when buildings are to be significantly altered or demolished.
This is the first step in identifying whether your property or land is suitable to support roosting bats, and indeed may identify whether bats are already present. PRAs can be carried out throughout the year.
