Selling a House with Japanese Knotweed

    Yes, you can sell a property with Japanese Knotweed — but there are legal requirements and practical steps you must follow.

    Legal Disclosure Requirement

    You are legally required to disclose Japanese Knotweed on the TA6 Property Information Form. Failure to disclose can result in the buyer suing you for misrepresentation, even years after the sale.

    Steps to Sell Successfully

    1

    Get a Professional Survey

    Commission a RICS-compliant knotweed survey to document the extent of the infestation and provide a formal report.

    2

    Start Treatment

    Begin professional treatment immediately. Having treatment underway shows buyers you're addressing the issue.

    3

    Obtain Insurance-Backed Guarantee

    A 10-year IBG is essential for mortgage lenders and buyer confidence. It transfers to the new owner.

    4

    Prepare Documentation Pack

    Compile survey reports, treatment records, guarantees, and specialist contact details for conveyancing.

    5

    Disclose on TA6 Form

    Answer 'Yes' to the knotweed question and attach all supporting documentation.
