Source: gov.uk (2025-09-25)

Register for a licence to survey great crested newts for  scientific, research or educational purposes, including informing development projects - and report actions taken under a licence.

This licence allows you to survey great crested newts using:
- pitfall traps – you must tell Natural England (#using-pitfall-traps) before you use these traps
- hand
- nets
- torches
- aquatic funnel traps (including bottle traps)
You cannot use box traps.

You must release all great crested newts you capture as soon as you’ve finished examining them.

You must apply for an individual licence (https://www.gov.uk/government/publications/survey-or-research-licence-for-protected-species) or a level 1 licence (https://www.gov.uk/government/publications/great-crested-newts-survey-or-research-licence-level-1) for survey, research or conservation work not covered by this licence.

For development work affecting great crested newts, you must apply for a mitigation licence (https://www.gov.uk/government/publications/great-crested-newts-apply-for-a-mitigation-licence).

When using pitfall traps you must:
- tell Natural England at least 5 working days before installing fences and traps using the Pitfall traps: notify Natural England before use form (WML-CL09) on this page
- only use a maximum 20 metre fence line and 15 pitfall traps per site
- avoid obstructing or significantly disrupting natural migration patterns
- check pitfall traps at least once a day between 6am and 11am
- make sure fence and trap designs comply with guidelines
- not use pitfall traps over the winter
- not ring-fence ponds
- not leave fences in place for more than 20 days

References

You usually need to provide at least one reference to support a survey or research licence form (https://www.gov.uk/government/publications/reference-to-support-a-protected-species-licence) when you register for this licence if you:
- have not held a licence for the species or a similar species for the last 3 years
- have a licence but want to add new methods
Report the actions taken under the licence

You must report in a survey licence return form any actions that are taken under this licence. Complete and submit the survey licence return between 1 and 31 October each year, even if you’ve taken no action or did not find target species. You’ll need to provide the names of any accredited agents who carried out the surveys on your behalf.

If you need to submit your survey licence return form outside these dates (for exceptional reasons only) email xxx@xxx.xx (mailto:xxx@xxx.xx).

The actions that you report in the form should contain information about the use of the licence from 1 October to 30 September. For each water body (for example, a pond or lake), you must record:
- the survey location (10 figure Ordnance Survey grid reference and county)
- the start and end date of the period that surveys took place at each water body
- the purpose of your survey
- whether great crested news were present or absent
- peak counts of adult and juvenile great crested newts
- the number of newts recorded by each licensable method
- results of egg searches, if conducted
- results of eDNA surveys, if conducted
- a Habitat Suitability Index score for each water body, if recorded
- presence of other amphibians, if found (native or non-native)
- presence of non-native plants, if found
You will not need to provide the results of surveys where you:
- did not use any of the licensable methods
- completed the survey under a different licence, such as a mitigation licence or project licence
- completed the survey as an accredited agent or assistant on someone else’s licence

If you or your accredited agents used licensable techniques, you must also send your results to the Local Record Centre. You can do this by recording your results on the iRecord website (https://www.brc.ac.uk/irecord/) or contacting your Local Record Centre (https://www.alerc.org.uk/contact.html).

Using your licence for another year

By reporting your actions, you can continue to use the licence for the following reporting period. If you will use the licence for surveys to inform development projects, you will need to pay £35 to continue your registration for another year.
