The RICS' updated guidance on Japanese Knotweed

Published: 29/01/2022 By Tom Bloomfield






I’m pleased to see the RICS have recently revised their 2012 guidance on dealing with Japanese Knotweed, including an acknowledgement that it rarely causes structural damage to robust buildings and their view that exaggerated media reporting has skewed public perception of the plant.

Although ignoring Japanese Knotweed is not an option, new advice includes favouring control over eradication and gives revised guidance on how surveyors should assess the risk knotweed poses and what effect it may have on the value of a property.

I’m no expert on knotweed, but I have seen sales compromised by the presence of the plant; I hope this guidance is taken on board by lenders.

Here is the full RICS guidance note.
