BNG Requirement for Small Sites

From 2nd April small sites are required to demonstrate biodiversity net gain as a condition of planning consent (unless exempt). Small sites are defined as:

  • residential development where the number of dwellings is between 1 and 9 on a site of an area 1 hectare or less, or if the number of dwellings is unknown, the site area is less than 0.5 hectares
  • commercial development where floor space created is less than 1,000 square metres or total site area is less than 1 hectare
  • development that is not the winning and working of minerals or the use of land for mineral-working deposits
  • development that is not waste development
