Regulation 25 Material changes in development
A liable person must inform Natural England by notice in writing of a material change in the details of the relevant development which were used to calculate the levy amount.
A notice under paragraph (1) must include the updated details of the relevant development, including a description of the material change.
Natural England must recalculate the levy amount under regulation 24 where it—
receives a notice under paragraph (1), or
otherwise becomes aware of a material change in the details of the relevant development which were used to calculate the levy amount (and see regulation 37 which provides for a surcharge to be imposed).
When recalculating the provisional amount for that purpose, the reference in regulation 24 to the details of the relevant development is to the updated details of the relevant development.
