Recently, many banks and building societies have refused mortgages on properties affected by Japanese knotweed. In many cases this has included knotweed plants located on adjacent properties up to 30m away!

However, guidance published by the Royal Institution of Chartered Surveyors (RICS), is changing this. In addition to better guidance for surveyors undertaking mortgage valuations, the Council for Mortgage Lenders and the Building Societies Association advised the Japanese knotweed treatment industry that they should form a trade body. This was duly done in April 2012, when the Invasive Weeds Control section of the Property Care Association (PCA) was formed. Through the RICS guidance and PCA trade body, surveyors and mortgage lenders now have a system in place to help them determine and understand the risks associated with Japanese knotweed growing on or near a property. This should prevent many banks and building societies from refusing mortgages due to their previous difficulties in quantifying risks from Japanese knotweed.

If need be, the lender may require the cost of any knotweed treatment works to be taken off the value of the property affected. In such cases, Weedtec can arrange for these costs to be fully secured and protected as a bond payment, through Bondpay. Other warranties and insurance packages can also be provided depending on the requirements of each project.
