What this ground & environment checker shows
Enter a UK postcode or town to map flood zones, historic landfill sites and coal mining referral areas around a location. Use it as an early screen when buying, developing or investigating ground conditions — then follow up with specialist reports where risks appear.
Flood zones
Environment Agency flood zone overlays near the pin, with Zone 2 and Zone 3 highlighted where present.
Historic landfill
Nearby historic landfill sites on the map and in a clickable list, useful for contamination and development checks.
Coal mining referral areas
Mining Remediation Authority referral layers that flag where past coal mining may need further assessment.
Buying & development due diligence
Ground hazards affect insurance, planning and lenders. Screen early, then commission full reports if anything material shows.
How to check ground and environment risks
- Enter a UK postcode (e.g. YO1 8SU) or a town name, or use your current location.
- Choose a radius from 250 m to 2 km depending on how wide an area you want to screen.
- Review the flood, mining and landfill badges, then explore the map overlays.
- Click landfill names or flood areas in the side panels to focus them on the map.
- Treat this as a first-pass open-data screen — not a substitute for a survey, mining report or environmental search.
Ground & environment FAQ
How do I check flood, landfill and mining risks near a UK postcode?
Enter a postcode or town and choose a radius. We geocode the location, then map nearby flood zones, historic landfill sites and coal mining referral areas from official open datasets.
What data does the ground and environment checker use?
Flood and historic landfill layers come from the Environment Agency. Coal mining referral areas come from the Mining Remediation Authority. The basemap is OpenStreetMap.
What is a coal mining referral area?
It flags places where past coal mining may affect development or conveyancing. Lenders and planners often expect further assessment or a mining report if a site sits in or near one.
Why check ground and environment before buying a property?
Flood risk, historic landfill and mining legacy can affect insurance, development options and saleability. Mapping these layers early helps you decide whether to commission specialist reports before exchange.
