Japanese Knotweed Eradication Cost Overview

The cost to remove Japanese knotweed generally ranges from £1,000 for minor herbicide applications to over £200,000 for extensive commercial excavations.

For homes, eradication costs typically fall between £1,000 and £39,000, depending on the affected area’s size and whether herbicide treatment or excavation is required.

Why Choosing Cheap Removal Services Can Be Costly

While low-cost Japanese knotweed removal services may seem appealing, opting for a trusted, experienced company ensures long-term savings and effective eradication. Improper removal can leave behind small rhizome fragments, causing the knotweed to regrow and spread. A reliable treatment plan and warranty are essential to prevent recurring issues. We pride ourselves on transparent pricing to give you confidence in our services.
