Although it is illegal to let Japanese Knotweed spread from your property, it is not illegal to simply have it on the grounds. This means that even though the presence of Japanese Knotweed in your or your neighbour’s garden is devaluing your property, there is no obligation to treat it. However, if it is present on your land we highly advise you to start the eradicating process. The presence of Japanese Knotweed, especially if it is on your land will mean that potential buyers will struggle to get a mortgage to lend against the property where Japanese knotweed is located on or near.

We would, therefore, recommend a site survey report in this instance, it would ensure that you would receive the full details of the Knotweed, which may result in the value of the property being maintained as opposed to the proposed devaluation. The site survey will give us details such as:

• Age of stands
• Site location
• If the Japanese Knotweed has caused any structural damage
•  

This documentation is recognised by mortgage lenders. To start eradicating Japanese Knotweed in Crewe we would then recommend a management plan, as this outlines the treatment process, the cost of the treatment and a schedule of works.
