Norfolk Police are continuing to see a rising trend in the amount of reports they receive involving bat roosts being destroyed or disturbed. They currently have a number of ongoing investigations because of the planning process which causes these come to light. Sadly, dealing with bats in properties can incur extra costs to the project but it is not an excuse to ignore them and cut corners. It could end up being far more expensive in the long run and delay the process even further.
All bat roosts are protected, whether they are being actively used at the time or not, there are no defences for destroying or damaging a roost without the relevant Natural England licence in place before the work starts. Should you discover a bat or evidence of bats in an area you are working, you should cease work immediately and seek expert advice.
