What we do
Bats inhabit a broad range of habitats throughout the UK, including built structures, trees and natural rock formations and cave systems.
Middlemarch Environmental has a team of experienced, licensed bat workers who can carry out all types of bat surveys and assessments. We can also design mitigation and apply for development licences where required, and we are one of the few consultancies that currently offer Natural England’s Low Impact Licence service.
Bat Surveys and Assessments
Our team of experienced bat workers includes are able to carry out the full spectrum of bat surveys works described in the current best practice document Bat Surveys for Professional Ecologists: Good Practice Guidelines , published in 2016 by the Bat Conservation Trust. Our survey capability includes:

- Preliminary ground level roost assessments of structures and trees.
- Tree climbing surveys to inspect potential roost features in trees.
- Nocturnal emergence and dawn re-entry surveys to determine roost status of structures and trees.
- Back-tracking surveys to identify roost locations.
- Manual and automated site-wide bat activity surveys (combining walked transects and the use of static detectors).
- Specialist bat trapping surveys using mist nets, harp traps and acoustic lures.
Middlemarch is also experienced in the design of site-specific survey methodologies for complex sites where standard survey techniques cannot be implemented.
Bat Mitigation & Development Licensing
For sites where the presence of bats is confirmed, works generally need to be controlled by a development licence from Natural England, or by a Bat Protection Strategy where potential impacts can be avoided.
Middlemarch has extensive experience of designing and implementing bat mitigation, and has been the named ecologist on a large number of development licences throughout the UK.
Low Impact Bat Licence
Natural England recently introduced the Low Impact Bat Class Licence scheme, wherein a small number of the UK’s foremost bat consultants are now able to issue development licenses for projects deemed to have a low impact on bats, without the need for further consultation with Natural England.
A low impact licence can only be issued for sites supporting minor roosts for common bat species, but still ensures that works are undertaken in accordance with wildlife legislation and impacts are adequately mitigated.
In addition to bat surveys, Middlemarch Environmental can also provide the following related services:
- Bat ecological clerk of works
- Post development monitoring
- Bat box supply and installation
- Habitat creation and enhancement
