Japanese Knotweed Survey

If you are looking to buy or sell a property, you will likely require a full Japanese Knotweed survey to determine the presence or absence of Japanese Knotweed within the property boundaries.

Why do I need a Japanese Knotweed Survey?

Japanese Knotweed must be declared on a TA6 form due to the high possibility of damage occurring. For those who have Japanese Knotweed on their property, the effect it can have on a properties value and it’s potential to spread need to be stated. If you do not declare the presence of Japanese Knotweed, you may be legally accountable. Many mortgage providers will ask for a full survey to be undertaken prior to a sale and also have reassurance of a Japanese Knotweed removal plan.

Our highly experienced knotweed surveyors are members of the Property Care Associate (PCA). They are all trained to detect the presence of any invasive plant species within a property. This allows us to reassure you that any potential issues will be identified. The RICS Management Categories are taken into account when carrying out a survey at a residential property.

In the case of selling or buying a property that is affected by Japanese Knotweed, a knotweed assessment and report may be needed. This would be necessary in order for a buyer, or a seller, to obtain a mortgage. A survey and report document will provide formal Japanese knotweed verification, as well as a more accurate plan of where Japanese Knotweed is within the property. It also describes the RICS Management category assessment identified, and recommendations on the most effective remediation strategy for the property.

Japanese knotweed is a nightmare. Not only is this invasive plant a hazard to biodiversity, you’re also faced with a host of legal responsibilities to stop it spreading onto neighbouring land and the potential of facing legal action if you do.

The Property Information Form (TA6) is a document used by sellers to give prospective buyers important information about the property so that they can make an informed decision. This includes things like parking, alterations to the property, insurance and environmental matters such as energy efficiency and the like. One of the main environmental aspects of the form is information regarding Japanese Knotweed. The TA6 form addresses concerns with the following question: “Is the property affected by Japanese Knotweed?”

The form provides three possible answers to the question: Yes, No, Not known

Should the TA6 form of a property you are considering buying state ‘Not known’ concerning Japanese Knotweed, then you may want to conduct a Japanese Knotweed survey at your own expense.

The presence of Japanese Knotweed will most likely affect the valuation of a property. If Japanese Knotweed is present on or near to a property, mortgage lenders often require evidence of a suitable treatment programme as a condition of lending. A 10 Year Insurance Backed Guarantee must also be in place upon completion. Read our Knotweed and mortgages advice for more information.

Your property’s value is closely tied to its condition, as well as issues highlighted in your property survey.

The physical damage caused by Japanese Knotweed will result in financial damage. This can be the costs required to repair your property, or the reduced property value. These result from damages and the poor condition of your property, as a result of Knotweed.

It is a legal requirement for surveyors to highlight the presence of Japanese Knotweed in their reports, meaning you will be required to treat it eventually. Treatment is much easier and faster when the Knotweed is first identified and it is smaller.
