At Protected Species Ecology Ltd we have three fully licensed bat ecologists covering all bat species, across all counties in England, Wales and Scotland. This means we are licensed to enter bat roosts, and to capture, handle and net bats for identification.

There are 18 species of bat resident in Britain, and they can use houses, trees, caves, barns and many other structures as roosts. All bats species are protected under UK and European legislation: which makes it an offence to kill, injure or disturb bats, or to obstruct access or damage their roosts, even when the bats are not there. So, before a Local Planning Authority can consider a planning application, we need to complete a bat survey and assessment.

We have been carrying out bat surveys since 1991. During this time we have surveyed more than 500 buildings within residential, agricultural, industrial and military sites. We have completed transect and static surveys of large wind farms, individual wind turbines and solar arrays. We have carried out surveys of hundreds of trees, often working alongside tree surgeons. David Lewns has held 38 EPS licences, and he has a solid track-record for designing and implementing successful mitigation schemes for bats, including custom built roosts, as well as adapting existing structures.

We work to local and national best practice guidelines, including the current Bat Conservation Trust (BCT) Survey Guidelines1.

A bat roost survey includes looking for evidence of bats and assessing the potential opportunities for bats to occur at a site. The next stage is to carry out bat activity surveys, most of which take place between April and October. These include dusk emergence and dawn re-entry surveys at roosts, and foraging/commuting surveys of sites. To assist us, we use a range of specialist manual and static detectors to record the bat echolocation calls; these are then analysed by our ecologists, to identify the species of bat.

If bats are found, we will explain the potential issues and conflicts, and advise clients on any modifications to the design or changes to the timing that may help them avoid the need for a licence. If a (EPS) licence is required, we will complete the bat licence application on our client’s behalf, and liaise with the licensing authority, planning authority and contractors to ensure a successful outcome for all.

Bat surveys are completed in advance of submitting a planning application; and this can mean unexpected delays for some clients. We encourage clients to discuss their plans with us as soon as possible, to ensure the surveys are timed to best effect, and delays are minimised.
