Commercial Land Owners

Protect your investment

To ignore knotweed on land that you’ve invested in for development or to incorrectly treat knotweed, can prove costly in the long term. This is why we work with you to devise the most appropriate remediation solution based on the proposals for the site. Our methods are fully compliant with legislation and codes of practice and ensure that your land can be remediated for its designated purpose.

Furthermore, Japanese knotweed needs to be disposed of in a licensed landfill by professionals with contaminated waste removal licences. Japanese Knotweed Ltd. can take care of all these problems for you with our highly trained and accredited professionals.

Whether you are at the pre-purchase stage, or have already invested in a brownfield site we can ascertain via survey whether it is contaminated with Japanese knotweed. Contamination is a concern for remediation of these sites, but does not mean you should not consider investing. If Japanese knotweed is found we can excavate and remove it for you so your plans can proceed.


You may qualify for a Land Remediation Relief tax application on current projects or historic projects up to 3 years. Find out more:

Commercial Property Owners

Japanese knotweed can be a menace for commercial property owners. If left untreated it will create thick screens of bamboo-like growth. It is highly resistant and can’t be killed with conventional means such as pulling or strimming.

Knotweed can damage buildings and underground drainage systems in its search for water – as it grows it will creep through any crack or gap in the ground, damaging parking spaces and pathways. It can also pose a health-and-safety risk to consumers by blocking off or creating uneven hard surface areas.

We can help

Japanese Knotweed Ltd offer a range of treatment options for commercial property owners such as herbicide spraying that will keep the knotweed in check and force it into a dormant state leaving your property and its visitors safe. Contact us today for a free* survey today.

Facilities Management

Our weed control services are the ideal cost effective solution for property management companies that are required to keep areas of access clear of weeds. We also work with property and facilities management companies in the same way.

As their approved contractor we control Japanese knotweed on land that is under their management. The Resident Management Company (RMC) approves the costs for such services to be included in the Service Charge budget so it is important they can rely on us to get it right. It is also key to have weed control treatment documented for residents wishing to buy or sell their property, so let us take that pain away from you and provide the service and the report, to keep your clients and residents happy.

The average cost to remove Japanese knotweed varies, depending on the methods involved and the size of the affected areas. If it is identified and dealt with promptly, the costs of removing Japanese knotweed can be kept to a minimum. Long-term herbicide treatment is usually the most cost-effective control method. Our professionally delivered herbicide treatment programme will provide successful chemical control of Japanese knotweed within a period of 3-7 years.

Excavation of Japanese knotweed costs more than herbicide treatment due to labour, materials, waste removal and reinstatement costs. However, it ensures complete Japanese knotweed removal allowing free use or development of the property. We provide cost-efficient excavation due to our extensive experience whilst minimising waste volumes.

As knotweed is an invasive species classed as “controlled waste”, it can only be removed by licenced organisations. It must be disposed of safely at a licensed landfill site by a registered waste carrier. We do not advise you try to undertake this operation yourself.


Land Remediation Tax Relief (LRR)

Originally LRR was designed to encourage investment in land that was previously derelict or contaminated so it can be made purposeful again. It is a generous tax incentive intended to promote the remediation and development of land and buildings affected by Japanese knotweed or chemical contaminants such as Asbestos.

It helps offset some of the cost of remediation services (which can include man-hours on the project, such as the Project Manager) through capital gains tax relief.

We can provide you with the best and most up to date industry information and advice on whether you can claim, and if so how to kickstart the process. Contact us by clicking the button.
