Bat Emergence Surveys for Planning Applications

Bat Emergence Surveys across the UK

What Is a Bat Emergence Survey?

A Bat Emergence Survey, sometimes called a dusk emergence or dawn re-entry survey, observes bats leaving or returning to their roost. Using professional equipment such as bat detectors and night-vision technology, our team records:

Whether bats are present
The number of bats
The species present
Roost access points
Patterns of activity around the structure

These surveys follow Natural England and Bat Conservation Trust (BCT) guidelines, ensuring full compliance.

When Do You Need a Bat Emergence Survey?

A bat emergence survey is required when:

A PRA indicates moderate or high bat roost potential
Your development involves roof works, demolition, loft conversions, or tree removal
Planning officers request further bat activity data
There are signs of bats such as droppings, staining, or suitable entry points

Seasonal constraint: Bat emergence surveys can only be carried out between May and September, with optimal conditions in warm, dry weather.

Our Bat Emergence Survey Process

We make the ECIA process straightforward:

1. Review & Planning - We assess all existing information and create a survey plan tailored to your site.
2. Dusk & Dawn Surveys - Ecologists attend your site during dusk, dawn, or both to record bat activity using specialist bat detectors, thermal imaging, and night-vision equipment.
3. Data Analysis - All recordings are analysed to identify species, behaviour, and roost status.
4. Mitigation & Licensing - If bats are present, we provide practical mitigation strategies and support Natural England licence applications where required.
5. Planning-Ready Report - You receive a clear, professionally written bat emergence report designed to satisfy planning requirements.
