Why Schedule a Japanese Knotweed Assessment?

A Japanese knotweed assessment involves a detailed site evaluation by PCA-certified professionals to identify knotweed presence, evaluate infestation severity, and recommend an effective eradication strategy. This complies with the latest RICS guidelines and addresses legal and mortgage obligations.


Early assessment can prevent property damage, legal issues, or delays in real estate transactions. The report includes a comprehensive site analysis, annotated maps, photographic documentation, and a tailored Knotweed Eradication Plan.

For Homeowners and Property Buyers

If you're buying or selling a property, lenders and surveyors often require a formal knotweed assessment. This confirms professional management of the infestation, facilitating mortgage approvals or reassuring buyers.

For Developers and Commercial Projects

Before starting groundworks or purchasing a site, an assessment identifies invasive species early, preventing project delays and enabling a cost-effective removal plan integrated into your timeline.

Our assessments are available year-round, with optional canine detection for low-visibility conditions.

Assessment Costs

A RICS and Japanese knotweed assessment starts at £249 + VAT. If you opt for our Knotweed Eradication Plan, the assessment fee is deducted from the treatment cost.
