What this data does — and doesn't — cover

  • Licensed-era records only. Waste licensing began in 1974. Older tips — especially small pre-war ones — are incompletely recorded, so absence from this data does not mean no landfill ever existed here.
  • Not the contaminated-land register. Councils hold a separate register of land determined as contaminated. A historic landfill entry is not a contamination determination, and vice versa.
  • Boundaries are indicative. Digitised at 1:10,000 scale; some are buffers around a point rather than surveyed edges.
  • Not a substitute for a formal environmental search. If you're buying, your conveyancer's environmental search checks this and several other sources.
