How to apply for a hazel dormouse mitigation licence (A35)

Updated 1 April 2025

Applies to England

To apply for a mitigation licence, you need to complete the latest version of the:

• application form
• method statement – to show what you’ll do to reduce the impacts of the proposed work on hazel dormice
• work schedule – to show when you’ll do the activities and in what order

You may also need to provide:

• a reasoned statement to show that the activity fits the criteria and that there is no satisfactory alternative 

• references to show that the ecological consultant has the necessary experience to apply for a mitigation licence (references will not be needed if they’ve been named on a mitigation licence for hazel dormice issued in the last 3 years)

If the work is part of a phased development (requiring more than one licence application) or multi-plot development, you must submit a:

• hazel dormouse master plan

• habitat management and maintenance plan

You should attach these as separate documents alongside your application. 

To understand what needs to be included in your master plan, you can use the archived guidance on great crested newt master plan requirements as a guide.

Use the European protected species (EPS) licensing policies 

As part of your mitigation licence application, you may be able to use the EPS licensing policies to: 

• reduce the level of survey you need to carry out 

• reduce the mitigation requirements 

• improve flexibility on where you create habitats as a compensation measure

You need to send all required forms together with the application form.

Request a change to your existing licence 

For all changes, you must: 

• complete the modification request form 

• include the licence reference number 

• have both the ecologist and the licensee sign the form 

• include any amended documents or figures, dated appropriately, as stated on your request form (highlight changes within documents and strikeout deleted text) 

For a change of licensee, you must include: 

• a letter or email from the previous licensee explaining what is proposed 

• a letter or email from the new licensee confirming that they accept the agreed mitigation proposals relating to the licence 

• an application form with sections 1, 18 and 19a completed by the new licensee 

For a change of named ecologist, you must include: 

• a letter or email from the previous ecologist explaining what is proposed 

• a letter or email from the new ecologist confirming that they accept the agreed mitigation proposals relating to the licence 

• an application form with Sections 2, 10, 18 and 19b completed by the new ecologist

Natural England will decide whether to issue a licence within 30 working days of receiving your application.

If your licence was issued before 2015, meaning it includes a licensed method statement, you must:

• provide a summary of progress stating what has been completed and what is left to complete 

• provide a summary of the animals captured or disturbed during the licensed works so far 

• include a list of the changes to the licensed method statement and other documents 

• state whether there are any implications for the ‘favourable conservation status’ of the licensed species as a result of the proposed changes 

• include an updated method statement, dated appropriately, with all changes clearly highlighted (even if you only need to modify the work schedule) 

• include all maps and figures that support your method statement
