What to know about Japanese Knotweed

Location is an important factor when searching for a new home, but it's essential to take the time and examine potential properties inside and outside.

While your green thumb might've been limited to growing some basil on your windowsill before now, you'll want to be knowledgeable about Japanese knotweed - this perennial plant can cause major headaches with its ability to penetrate foundations, walls, floors and asphalt.

Homeowners should make sure they are aware of any signs that this plant may have taken hold in their garden, so they don't face costly repairs later down the line.

To ensure your home purchase goes as smoothly as possible, you may wish to consider commissioning a RICS Homebuyer’s Survey. This professional survey inspects for any potential risks in the property and its vicinity - including Japanese Knotweed which can be of particular concern when seeking out mortgage or insurance products. 

Trained surveyors will identify if knotweed is present so that buyers can make an informed decision about their prospective new home with added protection against undetected issues.

For those considering properties with a Japanese knotweed presence, lenders may be willing to make exceptions if the plant is being professionally removed and accompanied by an insurance-backed guarantee. Eradicating Japanese Knotweed can come at a cost of around £3,000 – however, obtaining indemnity insurance provides up to £20K in protection against costs associated with future re-emergence or market value loss.
