Japanese knotweed is listed on Schedule 9, and subject to Section 14, of the Wildlife and Countryside Act 1981 which makes it an offence to plant or otherwise cause this species to grow in the wild. There is no explicit obligation upon landowners to manage this species on their property. However, they must prevent it spreading off their property.

Defra is not currently considering offering funding for homeowners for the treatment and removal of Japanese knotweed. Guidance remains available for homeowners who do wish to manage Japanese knotweed on their property: How to stop Japanese knotweed from spreading - GOV.UK.
