    Landlord Responsibilities for Japanese Knotweed

    Letting a property with untreated knotweed exposes you to criminal liability, civil claims and lost portfolio value. Here's what UK landlords must do.

    ASB Act 2014

    Up to £2,500 fines and Community Protection Notices for failing to control knotweed.

    Civil Liability

    Neighbours can sue for diminution in value — typical settlements £10,000–£40,000.

    Mortgage Risk

    Tenanted properties with knotweed become unsellable and unmortgageable.
