In Britain, all bat species, and their roosts are fully protected by law. The government is strict when it comes to removing those types of bats from your property. If you buy a house, and it’s inhabited by bats, you are advised to leave them alone. If you need to have work done on an area of the house where bats roost, you may need to hire a bat expert to do a survey, and you should call the Bat Trust for advice. If you cannot avoid harming bats or their habitats with the work that needs to be done, you need to apply for a mitigation licence from Natural England. Sometimes they will make arrangements to move the bats to a separate bat structure away from the house.
