I'm pretty sure that bats are only recorded as "rare" because so many people who have them keep bloody quiet about it as they fear the consequences.Seems to be the way these days in nearly all aspects of life.
OT but a while back I was watching a tv prog about folk renovating an old property. They found possible bat activity and did the right thing, stopped the works and informed bats.gov.uk. What then followed was months of largely being able to do nowt, I think it was closer to a year. This was due to reports needing to be written and if I recall correctly needing to wait until a certain time of year so the agency could determine for sure if there was activity.
The end result? The agency confirmed there was no current bat activity, no recent bat activity, and the (nesting?) area most likely hadn't been used for years.
The delay cost the owners not only in time but also financially.
I won't be popular for typing this, however when I read stuff like this part of me thinks 'why didn't you just bash on'.
Our ex-next door neighbour had them in their loft. They flew over our garden in the evening. I mentioned it to him once. I saw chinks of light from their roof tiles for a few weeks, the loft was full of floodlights. No more bats seen after.
