Due in part to buyers and sellers rushing transactions to win stamp duty holiday savings, Legal claims against vendors over Japanese Knotweed have risen sharply over the last year.

Over many years, Japanese knotweed has acquired a reputation as one of the most invasive plants and has been blamed for causing damage to properties. A message from A specialist knotweed treatment firm Environet UK, says there has been a 25% year-on-year increase in misrepresentation cases because a seller has failed to declare the presence of knotweed on their property.

Environet says the Law Society’s TA6 form, completed as part of the conveyancing process, requires sellers to state whether the property is “affected” by Japanese Knotweed.

Firstly, the plant's remarkable ability to force its way through concrete or brick means it can damage buildings or roads. Secondly, it grows in dense clusters that exclude native species. Thirdly, it is almost impossible to eradicate.

Japanese knotweed can devalue a house between 5-15%, however, in some more extreme cases, the plant has been known to almost completely devalue properties. The amount that a home is devalued by will depend on the severity of the infestation and its proximity to any buildings hence PropertyHubLtd suggest for our landlords and Vendors to start the treatment while the property is empty as it can take up to 5 years to completely remove Japanese knotweed through chemical treatments. However, it can be eradicated immediately through excavation, which involves digging it up out the ground. Although this is a more expensive alternative to the more commonly used chemical treatment.
