The seller of a property has the legal obligation to disclose the presence of Knotweed on the land of the property. In fact, there is a specific question relating to the presence of knotweed on the Law Society TA6 forms. Failure to answer this question untruthfully during the conveyancing process could result in a claim of misrepresentation possibly being bought against you.
As the appearance of knotweed changes over the seasons, use our seasonal guide to help you identify whether you have knotweed on your property, you can find this here.
If you are still unsure, please fill out our online enquiry form, submitting a photo of the plant. We will get back to you as to whether you have a potential knotweed issue.
Japanese knotweed is not poisonous – in fact it has been used in cooking recipes for many years!
Whilst it is not illegal for Japanese knotweed to be on your land, Japanese Knotweed is controlled under a number of laws and legislations including:
By not aiming to control the prevention of spread to neighbouring land, or by moving contaminated soil or cuttings without disposing of it at a licenced landfill, the legislation could be enforced to control the spread. This can result in up to £5,000 fine or two years in prison!
In Britain, Japanese knotweed grows unabated and at its most prolific, it can grow up to 20cm in height in a day! With no known natural predator the roots can reach up to 3M deep and are able to break through concrete, tarmac and drainage systems, creating many damage issues for the foundations of your home and neighbouring properties. Due to its destructive nature, mortgage lenders are reluctant to lend on a property with knotweed, unless there is some form of treatment guarantee in place, which could result in your property being significantly down valued.
Japanese knotweed starts growing around early Spring and can reach up to 1.5-2M by May, 2.5- 3M by June, before dying back between September and November.
