Boundary map
What these waste types mean
- Industrial:
- factory and process waste. Contents vary widely — some benign, some not; the site's operator and era are the clues.
- Household:
- everyday domestic refuse. Decomposes and can generate landfill gas for a few decades after closure.

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.
