Contaminated land + landfill

Band:lowLandfill:low

EA landfill register shows no nearby activity. Note: this LA has no wired register adapter; a Stratum Environmental Search is still recommended for full Phase IIA coverage.

Contaminated-land register coverage is partial; only Local Authorities with a wired adapter are queried. EA landfill data is national. A "low/none" verdict from this lookup is NOT a guarantee that the property is uncontaminated; commission a full EA Environmental Search through a chartered surveyor before exchange.

Japanese knotweed

Sighting density:medium

Some knotweed sightings recorded in this postcode area. A site visit by the buyer or surveyor should look for visible canes, particularly along garden boundaries and watercourses.

Knotweed band is proxy-derived from INNS / iRecord public sightings aggregated to postcode-area resolution. It is NOT a property-level survey. A buyer should still rely on the seller's TA6 disclosure + a chartered surveyor's field check before exchange.
