Why Might I Need a Bat Survey?

When Should Bat Surveys Be Carried Out?

Bats and their roosts are legally protected across the UK under both UK and European law. If your development involves altering or demolishing buildings, working on trees, or developing greenfield land, a bat survey may be required by your local planning authority.

Our team will help you understand exactly what’s needed and when — so you can stay compliant and on track.

Not all surveys can be done year-round. Some must be timed carefully to avoid delaying your project.

  • Scoping surveys can take place at any time of year.

  • Emergence and activity surveys must be carried out between May and September — the key bat activity season.

  • Surveys must also be done in suitable weather conditions (dry, low wind, and temperatures above 10°C).

We always recommend speaking to us early in your project to avoid planning hold-ups.

    Scoping Surveys (Preliminary Roost Assessments)

    A site inspection to assess whether bats are likely to be present. We check for signs such as droppings, access points, and potential roosting features.

  • Emergence / Activity Surveys

    Carried out at dusk or dawn using ultrasonic detectors to identify species, access points, and flight patterns. Essential for determining if roosts are present and how they’re used.

  • Transect Surveys

    Ideal for larger or linear developments (e.g. wind farms or roads). These assess wider site usage by bats and can help inform habitat protection or mitigation.

  • Specialist Surveys

    Tailored surveys including eDNA testing, infrared monitoring, or additional seasonal assessments depending on your site’s needs.

Some bat FAQs

  • Potentially, yes — even small developments can affect bat roosts, especially if you're altering roofs, loft spaces, or mature trees. A scoping survey will help determine if further work is needed.

  • Most bat surveys are considered valid for 12–24 months, depending on the site and species found. If your project is delayed, we may need to carry out an update survey.

  • Bats are protected under UK and European legislation because they play an important role in our ecosystems and many species have experienced significant decline. All 18 species of bats in the UK (17 of which are known to breed here) are legally protected, along with the places they use for roosting and shelter.

  • It means you must not disturb bats or damage the places they roost — even if bats aren’t present at the time. Actions like blocking access to a roost, damaging a roof space, or removing trees without proper checks could be a criminal offence. That’s why a licensed bat ecologist should carry out surveys before any works begin.

  • It is a criminal offence to intentionally or recklessly disturb bats in their roosts, damage or destroy roosting places, or obstruct access to a roost — even if bats aren't present at the time. Penalties can include prosecution, fines, or delays to your project.

    A proper bat survey helps ensure you're acting within the law.
