Japanese Knotweed is an invasive plant that can damage footpaths, driveways, patios and in the worse cases, it can get into the property itself. It is very difficult and expensive to eradicate this plant. The discovery of Japanese Knotweed could affect the saleability, mortgage ability and value of the property.
If Japanese Knotweed is allowed to encroach onto the neighbouring property it may constitute a private nuisance under common law. It is against the law to try to remove Japanese Knotweed yourself, the plant is self-sowing and the smallest particle can reseed.
If Japanese Knotweed has been identified in a property you wish to purchase you should ask your legal adviser to request a copy of the ‘Japanese Knotweed Survey Report’. The report should cover aspects such as:-
- The relevant legislation
- Survey findings
- A detailed site plan showing the location of the knotweed
- Photographs of the knotweed
- The RICS Risk Category level
- Recommended remedial treatment complete with a programme of works and budget costs.
