In the United Kingdom, there are 18 known species of bats. These include both resident species that live in the UK year-round and some that migrate to the UK during the summer months. Some of the common species found in the UK include the Common Pipistrelle, Soprano Pipistrelle, and Daubenton's Bat, among others. Conservation efforts are in place to protect and preserve these bat species and their habitats in the UK.
