A Preliminary Inspection for Bats (PIB) 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 roof voids of the building. 

If signs of bats are found, or if the building is assessed as having potential to support roosting bats, further survey (Dusk Emergence and Dawn Re-Entry Surveys) will be recommended by the ecologist.

If bat droppings are found during the PIB, a sample will be taken for DNA analysis to determine the species of bat.  

A PIB 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 PIB can be undertaken at any time of year. 

PIBs are often conducted in conjunction with a Preliminary Ecological Appraisal

If you need a quote for a PIB, 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 PIB report to be delivered to you within 1 working day, following the completion of the survey.

Dusk Emergence and Dawn Re-Entry Surveys are surveys conducted by suitably experienced ecologists, to determine if a building is currently being used by roosting bats and, if so, how.  This involves positioning ecologists around the building 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 PIB.  

  • Negligible Potential - No surveys required.

  • Low Potential - 1 dusk emergence OR 1 dawn re-entry survey.  

  • Moderate Potential - 1 dusk emergence AND 1 dawn re-entry survey.

  • High Potential – 3 visits, comprising at least 1 dawn re-entry survey.  

  • Confirmed Bat Roost - 3 visits, comprising at least 1 dawn re-entry survey.  

Dusk Emergence Surveys begin 15 minutes before sunset and finish 1 hour and 30 minutes after sunset.  

Dawn Re-Entry Surveys begin 1 hour and 30 minutes before sunrise and finish 15 minutes after sunrise.  

 

Dusk Emergence and Dawn Re-Entry 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 and Dawn Re-Entry Surveys can be undertaken from May to September, inclusive.    

If you need a quote for bat survey, 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 Bat Survey report to be delivered to you within 2-3 working days, following the completion of the final survey.

 

Bat Activity Surveys

Bat Activity Surveys are surveys conducted by suitably experienced 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 conducted once or twice a month, beginning at sunset and finishing 2 hours after sunset.  

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.   

 ​

If you need a quote for bat survey, 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 Bat Activity Survey report to be delivered to you within 3-5 working days, following the completion of the final survey.

 

  

 

Winter Hibernation Surveys

Winter Hibernation Surveys are surveys conducted by an ecologist who holds at least a Class 2 bat survey licence, to determine if a building is currently being used by hibernating bats.  This involves inspecting the building internally for hibernating bats and signs of hibernating bats, such as faeces and feeding remains.  These surveys may be recommended by an ecologist following a PIB.  

Winter Hibernation Surveys are two-fold. The first element, is the deployment of static bat detectors in the areas of the building/structure, with potential for hibernating bats, over three visits during December, January and February. Secondly, a suitably qualified ecologist makes two checks in January and February, of all crevices/cracks in the building/structure for hibernating bats and signs of bats.

If you need a quote for Winter Hibernation Surveys, we answer quote requests within 24 hours.  

Your bespoke Winter Hibernation Surveys report is written in accordance with the current standards and guidelines, and is suitable for accompanying a planning application.

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 and Dawn Re-Entry Surveys, Bat Activity Surveys and Winter 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.
