Step 1: Request a Survey

It’s important to act quickly when dealing with Japanese knotweed, so we aim to offer a fast, efficient service. We can usually carry out a survey AND deliver our report within 3 to 5 working days. Choose from two different survey types:

Basic Survey

A survey to establish whether there is Japanese knotweed on site, and if so, where. We will recommend treatment options and provide a quote to follow through with our recommended treatment plan.

Comprehensive Survey

Includes a specialist report and detailed Japanese knotweed management plan (JKMP). The cost is refunded if you choose to proceed with a treatment programme.
£250 +VAT

When you book a survey, one of our invasive weed experts will attend your property and assess the severity of your Japanese knotweed infestation.

A basic survey is ideal if you simply want to know whether or not there is Japanese knotweed on your property. A comprehensive survey may be necessary if your lender requires a specialist report and JKMP. Feel free to get in touch if you’re unsure which survey type is right for you.

We are PCA members, so our specialist reports, treatment plans and insurance-backed guarantees are accepted by most lenders.

Step 2: Choose a Japanese Knotweed Treatment Plan

Our Japanese knotweed treatment plans can be broken down into two categories:
Herbicide Application and Excavation and Removal.

Knotweed Herbicide Application Plans & Costs

Herbicide application is more affordable than other methods of Japanese knotweed control. We use specialist herbicides that can only be applied by fully-qualified technicians.

Option 1: Herbicide applications as and when required – Starts at £75+ VAT per application.

Option 2: Three-year treatment programme and two-year monitoring period - Starts at £1,595+ VAT
  • Add a 5-year guarantee - Starts at £2,595 +VAT
  • Add a 10-year guarantee - Starts at £2,995 +VAT

An insurance-backed guarantee (IBG) can be added to any treatment plan with a guarantee, at an additional cost of £75.

Knotweed Excavation and Removal Plans & Costs

These knotweed removal programmes get rid of your Japanese knotweed quickly but usually cost more than our herbicide application plans.

Option 1: Excavation of Japanese knotweed and surrounding soil to be disposed of at a landfill site.*

Option 2: Excavation and relocation of Japanese knotweed and affected soil to another part of the site, followed by an application of our specialist herbicides.

Option 3: Burial of Japanese knotweed and contaminated soil in a hole dug on the site, enclosed in specialist weed proof membrane.

Our pricing for these services varies from site to site. As a guide, we charge roughly £850 +VAT per square metre (based on a minimum area of 10 – 15m2).

*Note: Landfill space is running out so the government have levied a tax of approximately £85 per ton of Japanese knotweed waste on top of the cost of haulage and excavation.
