Landfill Risk FAQ

How close is too close to a landfill?

Generally, properties within 250 metres of an active or historical landfill site are considered at elevated risk. Some lenders apply restrictions within 500 metres. Risks include ground gas (methane, CO₂), leachate contamination, odour, and vermin. Historical landfill sites (closed and capped) present different but often still material risks.[1]

Does landfill proximity affect mortgages?

Yes — some lenders will decline or require specialist surveys for properties within 250–500 metres of a landfill site, particularly if it accepted hazardous or putrescible waste. A Phase 1 environmental survey (desk study) is typically requested, which costs £500–£1,500.

Are old landfill sites still a risk?

Yes. Closed landfill sites can continue to produce ground gas (landfill gas) for decades as organic waste decomposes. They can also leach contaminants into groundwater. Many historical sites are not capped to modern standards and remain a material consideration for buyers and lenders.[2]
