Full Mitigation Licences
If your development project is likely to impact bats or their roosts, a European Protected Species Mitigation Licence (EPSML) will be required before work can proceed. This licence is issued by Natural England (or the relevant governing body) and provides legal permission to carry out activities that would otherwise be an offence under UK law, such as:
- Damaging, destroying, or disturbing a bat roost
- Obstructing access to a roost
- Capturing, injuring, or killing bats
EPSMLs are only granted once strict criteria have been met, including comprehensive survey data, a clear justification for the impact on bats, and a detailed mitigation and compensation strategy.
At Quantock Ecology, we specialise in complex bat mitigation licence applications, ensuring that your project remains fully compliant while progressing as efficiently as possible.
Do I Need an EPSML?
Not all projects require a full mitigation licence. In some cases, if only small numbers of common bat species are present within a low-conservation-status roost, you may be eligible for a Bat Low Impact Class Licence (BLICL). This fast-tracked licence is approved within 10 working days and can offer a cost-effective alternative.
However, if your project involves:
✅ A maternity roost
✅ A significant number of bats
✅ A high-conservation-status species
✅ A hibernation roost
… then a full EPSML will be required.
Our team will assess your site thoroughly to determine the most suitable licensing approach for your project.
Our Expertise in EPSML Applications
Quantock Ecology submits numerous EPSML applications each year for bats, as well as other protected species such as badgers and dormice. Our experienced consultants will guide you through the entire process, from initial bat surveys to licence approval, ensuring that all requirements are met for a successful application.
Our approach includes:
✔ Comprehensive bat surveys to provide robust data
✔ Tailored mitigation strategies to minimise project delays
✔ Expert guidance on licence conditions and legal obligations
✔ Full application preparation and submission to Natural England
We understand that every project is unique, and our team works closely with developers, homeowners, and planning authorities to ensure the best possible outcome for both our clients and bat conservation.
How Long Does an EPSML Take?
The EPSML process can take longer than other licensing routes due to the level of detail required. Natural England typically takes 30+ working days to approve full applications, though this can vary depending on seasonal demand and project complexity.
To avoid delays, we strongly recommend early planning and engagement with our team so that all necessary surveys and documentation are prepared in advance.
Your dedicated Quantock Ecology consultant will work closely with you to keep your project on track, ensuring deadlines are met wherever possible.
