It will halt Planning permission until a survey is done. If it's funded by the Building Company, they will likely as not get the Plans passed

We had a heron on our roof early in the morning, thought initially that it was rodents. Until someone walking their dog told us what it was. Fortunately our ponds are netted.
We had summer roots here for years++, our boards needed replacing so we waited 2.5 years and the bats didn't return for some reason. We had them replaced, put up bat boxes then the Bat Conservation Group wanted to see our paper work to make sure that we had sought permission. Well no. Actually. My reply was that if a householder was unaware of bats being present ........ we heard no more.
