Details

This licence allows you to temporarily mark dormice by fur-clipping and to handle dormice in:

  • nests
  • nest tubes
  • nest boxes

You must release the dormice where they were captured as soon as you’ve examined them.

You must apply for an individual licence or a level 1 licence for survey, research or conservation work not covered by this licence.

For development work affecting hazel dormice, you must apply for a mitigation licence.

Register with Natural England

Before you can use this licence, you must register with Natural England using the registration form for a class licence.

What you need to pay

It costs £80 to register for a new CL10b licence.

It costs £35 a year to continue your registration.

You must declare the intended use of the licence on your registration form. This will determine if you need to pay, such as to survey hazel dormice for development projects.

Natural England will refund unsuccessful applications.

When you do not need to pay

You do not need to pay if the licence is used for:

  • voluntary purposes - any work you do is unpaid and you are registered with an organisation or charity as a volunteer
  • conservation, science or research purposes, and research related to the protected species is carried out by a student or an employee of an academic institution or research body or an environmental non-governmental organisation
