Our suggested solutions to your Japanese knotweed problem are laid out in detail in a document called a Japanese Knotweed Management Plan.

What is a Japanese knotweed Management plan?

Our suggested solutions to your Japanese knotweed problem are laid out in detail in a document called a Knotweed Management Plan.

We conduct a Japanese Knotweed Site Survey to determine the scope of the infestation, and then we provide a detailed report known as a Knotweed Management Plan that details the various methods of Japanese knotweed treatment that can be used to manage the plant and eventually get rid of it entirely.

When purchasing or selling a home in an area where Japanese knotweed has been identified, a Japanese Knotweed Management Plan is typically required by mortgage lenders. When Japanese knotweed is discovered on a construction site, the Environment Agency recommends establishing a Management Plan immediately.

Our Management Plan Solution

You won’t have any trouble finding a mortgage lender to work with when you use our Japanese Knotweed Management Plan solution. Included in our comprehensive Management Plans are:

  • Expert Survey of your Japanese Knotweed Problem.
  • A comprehensive report including a site map, a description of the knotweed’s location, and an estimate of the costs involved.
  • Treatment options
  • Scheduled monitoring visits
  • Guarantee from Knotweed Services
  • An optional insurance backed guarantee

How much does a management plan cost?

The cost of treating or removing Japanese knotweed will vary depending on the size of the infected area and the intended use of the land.

Most mortgage companies will accept a Herbicide Treatment Programme as proof that the knotweed has been effectively eradicated or is having ongoing treatment and being managed.

A full excavation of the affected land, disposal of the knotweed-infected waste, installation of a root barrier, and back-fill with clean soil may be recommended if herbicide treatment is not viable or if the affected area is to be disturbed (for example, turfing, paving, driveway, house extension, outbuilding).


Depending on the extent of the infestation, getting rid of knotweed can be a time-consuming process that lasts for months or even years. The origin, age and spread of the plant, as well as its location and current environmental conditions, are additional considerations in the development of treatment strategies.

Here at Knotweed Services, we like to keep our clients in the loop at all times, so we report on the status of our management plan and our progress at each stage. Since this is a significant investment on the part of the customer, we want to make sure they are comfortable with our goals and methods before we begin working to eradicate the knotweed.
