TEMPO assessment
Richmond upon Thames Council recently used the TEMPO assessment tool to grant a Tree Preservation Order for a horse chestnut tree.
Richmond upon Thames Council's Planning Committee granted a Tree Preservation Order (TPO) for a mature horse chestnut tree in Twickenham on 14 October 2026. The council used the TEMPO assessment tool, which scored the tree at 16, indicating it definitely merits a TPO, to protect it from potential removal.
TEMPO assessment is a standardised system used by councils to evaluate factors like arboricultural merit, expediency, and public amenity value of trees. This helps determine eligibility for Tree Preservation Orders, as seen in the recent decision by Richmond upon Thames Council.
