We have planning permission to build a ground floor extension, however, our neighbours have informed us and the council that they have "seen" bats "roosting" in our roof. We have no outside evidence of bats at all, droppings etc and yes there are bats that fly all over in the area we have seen no evidence of them entering our roof. However, it is looking like we will need to carry out a survey before work commences. Are you able to give me a quote for carrying out a bat survey ASAP. Many thanks, Helen
