What is Japanese Knotweed?
It is a fast-growing perennial which produces reddish-purple shoots.
What is the problem?
Japanese Knotweed grows incredibly quickly even if a small amount of root is left in the ground it can re-infest. It can cause physical damage to buildings and land, in turn reducing the value and marketability. It can also be expensive to control or eradicate.
How can Japanese Knotweed affect you?
You must disclose whether the property has Japanese Knotweed. If you are purchasing a property that has it, you must disclose it to your mortgage lender.
If it has a detrimental effect on neighbouring properties the Anti-social Behaviour, Crime and Policing Act 2014 states you as the homeowner could be prosecuted.
If it is present you will need to provide the buyer (or receiver if buying) a plan, from a licensed company for its eradication. This plan may be requested by your lender too. Essentially a plan is used to manage its eradication.
My property has Japanese Knotweed, what do I do?
Seek help from a professional using the Royal Institute of Chartered Surveyors website for a list of approved contractors. Remember, Japanese Knotweed must be disposed of in special licensed landfill sites as it is considered as “Controlled Waste”.
Can I insure against it?
If you are aware of the Knotweed, you cannot obtain insurance.
