What is a Japanese Knotweed Clerk of Works?

When you are a property developer and you discover Japanese knotweed on-site, you want a swift and effective way to remove this invasive nuisance weed. The Environment Agency details a certain set of procedures that must be followed in order to legally and safely remove Japanese knotweed from the immediate area, called the Code of Practice for Managing Japanese knotweed.

This Code of Practice details the ways of dealing with the problem on a property development or building site. These include:

  • Japanese knotweed treatment by herbicide
  • Excavating Japanese knotweed contaminated materials
  • Removing Japanese knotweed contaminated materials to landfill
  • Bund treatment
  • Burial of knotweed contaminated materials
  • Root barrier

Developers and builders in particular must follow the Environment Agency CoP and, in doing so, appoint a Knotweed Clerk of Works who will oversee the Japanese knotweed removal and treatment process.

What is a Knotweed Clerk of Works Responsible For?

A Japanese Knotweed Clerk of Works is responsible for a Knotweed Management Plan (KMP), which brings together all the important information that a landowner must be able to access both during and after the Japanese knotweed control programme. These documents, such as waste transfer notes, herbicide treatment records, cell burial location plans, landfill exemption certificates have legal implications and can be used in a court of law.

A Knotweed Management Plan records the decision-making process during a Japanese knotweed treatment plan and can be used to prove due diligence if the process is being disputed. It protects both the developer and the Japanese knotweed contractor in making sure that every process has been properly thought through.
