Preliminary Roost Assessment
T: 07443652988
A Preliminary Roost Assessement (PRA) is a survey conducted by an ecologist who holds at least a Class 1 bat survey licence, to determine if a building is currently being used or could potentially be used by roosting bats. This involves assessing the external elevations and the internal roof voids of the building.
If signs of bats are found, or if the building is assessed as having suitability to support roosting bats, further survey (Dusk Emergence Surveys) will be recommended by the ecologist.
If bat droppings are found during the PRA, a sample will be taken for DNA analysis to determine the species of bat.
A PRA and subsequent surveys are necessary to inform a planning application (and license from Natural England, if required), so that any proposed development works can continue lawfully without having a detrimental impact on roosting bats.
A PRA can be undertaken at any time of year.
PRAs are often conducted in conjunction with a Preliminary Ecological Appraisal.
If you need a quote for a PRA, get in touch and we will answer your quote request within 24 hours.
The report we provide is written in accordance with the current standards and guidelines, making them suitable for accompanying planning applications.
You can expect your bespoke PRA report to be delivered to you within 1 working day, following the completion of the survey.
For more information about PRAs, please check out our blog here.
Ground Level Tree Assessment
T: 07443652988
A Ground Level Tree Assessment (GLTA) is a survey conducted by an ecologist who holds at least a Class 1 bat survey licence, to determine if a tree is currently being used or could potentially be used by roosting bats. This involves inspecting the tree and the Potential Roosting Features (PRFs) for bats from the ground.
If signs of bats are found, or if the tree is assessed as having suitability to support roosting bats, further survey (Dusk Emergence Surveys) will be recommended by the ecologist.
If bat droppings are found during the GLTA, a sample will be taken for DNA analysis to determine the species of bat.
A GLTA and subsequent surveys are necessary to inform a planning application (and license from Natural England, if required), so that any proposed development works can continue lawfully without having a detrimental impact on roosting bats.
A GLTA can be undertaken at any time of year, but the optimal period is during the winter.
GLTAs are often conducted in conjunction with a Preliminary Ecological Appraisal.
If you need a quote for a GLTA, get in touch and we will answer your quote request within 24 hours.
The report we provide is written in accordance with the current standards and guidelines, making them suitable for accompanying planning applications.
You can expect your bespoke GLTA report to be delivered to you within 1 working day, following the completion of the survey.
Dusk Emergence Surveys
T: 07443652988
Dusk Emergence Surveys are surveys conducted by suitably experienced ecologists, to determine if a structure is currently being used by roosting bats and, if so, how. This involves positioning ecologists around the strucutre and recording where bats are emerging and entering.
The number of surveys required depends on the level of potential the building has been assigned during the PRA.
-
Negligible Suitability - No surveys required.
-
Low Suitability - 1 dusk emergence survey.
-
Moderate Suitability - 2 dusk emergence surveys.
-
High Suitability- 3 dusk emergence surveys.
-
Confirmed Bat Roost - 3 dusk emergence surveys.
Dusk Emergence Surveys begin 15 minutes before sunset and finish 1 hour and 30 minutes after sunset.
Dusk Emergence Surveys are required to inform a planning application and, once a planning application has been approved, to inform a license from Natural England.
Dusk Emergence Surveys can be undertaken from May to September, inclusive.
The report we provide is written in accordance with the current standards and guidelines, making them suitable for accompanying planning applications.
You can expect your bespoke Bat Survey report to be delivered to you within 2-3 working days, following the completion of the final survey.
If you need a quote for bat survey, get in touch and we will answer your quote request within 24 hours.
More information on Dusk Emergence Surveys can be found in our blog here.
Bat Activity Surveys
Bat Activity Surveys are surveys conducted by suitably qualified ecologists, to determine how a site is currently being used by foraging and commuting bats. This involves ecologists walking a transect route and recording all the bat activity on site, over visits carried out during April to October inclusive.
The transect route is positioned to encompass areas where bats are likely to forage and commute, with stopping points in areas where bat activity is likely to be high.
The number of Bat Activity Surveys required depends on the level of potential the site has been assigned during the PEA (between 7 and 14 visits).
Bat Activity Surveys are required to inform a planning application, if the development is likely to result in a significant adverse impact on foraging/commuting bats.
The report we provide is written in accordance with the current standards and guidelines, making them suitable for accompanying planning applications.
You can expect your bespoke Bat Activity Survey report to be delivered to you within 3-5 working days, following the completion of the final survey.
If you need a quote for bat survey, get in touch and we will answer your quote request within 24 hours.

Hibernation Surveys
T: 07443652988
Hibernation Surveys are surveys conducted by an ecologist who holds at least a Class 2 bat survey licence, to determine if a structure is currently being used by hibernating bats. These surveys may be recommended by an ecologist following a PRA.
Hibernation Surveys are two-fold. The first element, is the deployment of static bat detectors in the areas of the structure, with suitability for hibernating bats. The second element is a suitably qualified ecologist inspects all crevices/cracks in the structure for hibernating bats and evidence of hibernating bats.
Your bespoke Hibernation Surveys report is written in accordance with the current standards and guidelines, and is suitable for accompanying a planning application.
If you need a quote for Hibernation Surveys, we answer quote requests within 24 hours.
More information about Hibernation Surveys can be found in our blog here.
Bat EPSL
T: 07443652988
A European Protected Species Licence (EPSL), applied for from Natural England, allows otherwise unlawful activities to go ahead on site, where roosting/hibernating bats are present, and will be affected by the works.
EPSLs need to be informed by up-to-date survey data -Dusk Emergence Surveys, GLTAs, and Hibernation Surveys, where applicable. Full planning consent is required for an EPSL application.
If you need a quote for an EPSL, we answer quote requests within 24 hours.
An EPSL application will need to be approved by Natural England, which can take up to 30 working days upon submission.
