Japanese knotweed has been described as the most invasive alien species in Britain, first being introduced to the UK in the mid-1800s. It is prevalent across the entire British Isles and is often found on brownfield and wasteland sites. Its presence can have devastating consequences if not dealt with promptly, including legal implications and high removal costs of Japanese knotweed.
Identifying Japanese knotweed is not always easy. If you suspect that you may have an infestation, then our comprehensive Japanese knotweed identification guide provides clear guidance, or you can consult our guide to plants that are often mistaken for Japanese knotweed.
Our experienced staff are accredited with the PCA’s knotweed survey and contractor qualifications (CSJK), which support our provision of Japanese knotweed surveys for a wide variety of sites and domestic and commercial properties.

There are several proven methods for treating Japanese knotweed, each suited to different site conditions, timeframes and costs. Options range from multi-season herbicide programmes, reduced-dig approaches, capping solutions, installation of root barriers and membranes, treatment-bund formation, on-site burial and full excavation with licensed disposal. Each technique offers a different balance of speed, certainty and cost, making a site survey essential for selecting the most appropriate and effective approach.
