You can apply to register a biodiversity gain site, and record allocation of off-site gains to a development, if you’re: 

• an individual landowner or leaseholder  
• an agent acting on behalf of a landowner or leaseholder  
• an employee or representative acting on behalf of an organisation who is the landowner or leaseholder  

Before you apply 

If you’re an agent acting on behalf of the applicant 

You must be authorised by the applicant, which is either, the landowner, leaseholder or another person, to act on their behalf. They will need to complete an ‘authorise an agent to act on your behalf’ form. You must send this with your application form.  

If you are an employee or representative of an organisation, you do not need to complete an authorise an agent form.

How to apply

1. You will need to download and complete the relevant forms to register a biodiversity gain site and record allocation of off-site gains to a development. These will need to be sent to Natural England to be processed.
