Identify what you have found
The species you have found determines the licensing route, the survey requirements, and the likely delay to your project.
- Bats or bat droppings in a building, roof void, or tree being felled
- A badger sett within 30 metres of your works
- Great crested newts in or near ponds on or adjacent to the site
- Nesting birds in hedgerows, trees, or buildings during March to August
- Reptiles (slow worms, grass snakes) under debris or in vegetation
Secure the area and call an ecologist
Your actions in the first hours determine whether you face prosecution or a managed delay.
- Stop all work in the area where the species was found
- Establish a buffer zone (at least 30 metres for badger setts)
- Do not attempt to move, handle, or relocate the animal
- Contact a CIEEM-registered ecologist for an emergency site visit
- Record what was found, where, and when
Get an emergency ecological assessment
Your ecologist will confirm the species, assess the significance, and advise on next steps. Survey requirements are species-specific and season-dependent.

Understand the licensing requirements
Once surveys confirm protected species, you will need a wildlife licence from Natural England before works can resume. Allow at least 30 working days for determination, and budget for licence fees under the charging regime from April 2025.
Get a wildlife licence for your development
How to apply for EPS mitigation licences and badger licences, the three derogation tests, and devolved licensing.
Manage the project delay
The length of delay depends on the species and the time of year.
- Bats outside survey season (October to April): Up to 7 months until surveys can begin in May
- Bats during survey season (May to September): 3 to 6 months for surveys and licensing
- Badger sett outside closure window (December to June): Wait until July
- Nesting birds: 2 to 6 weeks until chicks fledge
- Great crested newts: Surveys March to June only; licensing adds 30+ working days
Identify which areas of the site can proceed unaffected while licensed works are resolved.
