The growth of japanese knotweed is an ongoing problem in many parts of the UK, and it can be particularly problematic for people who are moving home or seeking to develop land. However, despite the fact that it is an invasive species, it can be controlled by specialist contractors who have experience in dealing with the plant. It is also possible to eradicate it by using biological control techniques. These options can be expensive and time-consuming, but they can also be extremely effective.
Mortgage providers are increasingly aware of the potential impact that Japanese knotweed can have on a property and, as such, may require a specialist report from a PCA qualified Japanese Knotweed surveyor before they will lend money for a purchase. This is in addition to the requirement for a management plan to be in place to prevent spread of the weed.
It is also worth bearing in mind that the weed can be difficult to identify, especially in a rhizome state. Furthermore, the weed has the ability to grow in deep shade and it can grow around and over structures such as buildings, fences and paths. For this reason, it is advisable to hire specialist ecologists who are experienced in carrying out Japanese knotweed surveys and can provide a detailed site inspection and report that will detail the status of the weed within a plot of land or property boundaries.
Despite the increased awareness of the problem, it is still possible for mortgage lenders to miss the presence of Japanese knotweed, especially when a specialist is not involved. In some cases, it may be due to the weed being hidden or obscured by other plants and trees on the site, as well as it being located in difficult to access areas of the site. In other instances, it can be due to the surveyor failing to spot it as the weed has a tendency to change its appearance throughout the year.
There have been a number of instances where buyers have sued surveyors after a homebuyers’ or building survey has failed to pick up the presence of the weed. One such case saw a man awarded PS50,000 after his building survey missed the knotweed growing in his garden.
The cost of a Japanese knotweed survey will depend on who is carrying out the work and the size of the area that is being covered. As a general rule, the costs begin at PS250 + VAT.
A survey from a japanese knotweed survey specialists can be particularly beneficial to those who are looking for a property in an area that is infested with the invasive species, as it will give them peace of mind that the weed is being dealt with appropriately. It can also be a great option for those who are looking to undertake a land development project that would involve the excavation of a Japanese knotweed-infested site as the survey will allow them to carry out their plans while the weed is being treated.
