Best and most versatile agricultural land

The National Planning Policy Framework (NPPF) suggests best and most versatile as being "Land in grades 1, 2 and 3a of the Agricultural Land Classification (ALC). ALC is graded from 1-5 and based on yield, range and versatility of use, and need for input." The second sentance does not appear in the 2024 version of the NPPF but was added in the version issued December 2025.

For further information regarding development on agricultural land refer to the UK Gov and Natural England document: Guide to assessing development proposals on agricultural land.
