What these statistics cover

These figures describe applications collected by PlanningTrack for London Borough of Hillingdon, across all dates currently available. They are a partial dataset, rather than an authority-wide performance measure. The date range does not establish continuous historical coverage.

The approval percentage is approved records divided by approved plus refused records. Pending, withdrawn and unknown outcomes are excluded. No percentage is shown until there is an approved or refused record.
