Japanese Knotweed Expert is a nationally recognised specialist in Japanese knotweed and invasive plant removal. Most of our work centres on Japanese knotweed due to the impact it can have on property value and the legal issues it can create, so we often become involved early—identifying suspected plants, providing PCA-aligned surveys and RICS-compliant, lender-ready reports, and setting out clear eradication plans. From there, clients can choose to proceed with treatment through our team, use the plan for a property transaction, or rely on it to support a legal case with Part 35-compliant expert evidence.
Our approach is evidence-led and built to stand up to scrutiny, with reporting that is clear, defensible and relied upon in lending and legal contexts. We remove uncertainty where it matters most, helping property transactions move forward and disputes resolve with confidence.
Where timescales are tight, we move quickly, with reports typically issued within 24 hours and surveys arranged within 7 working days.
Free Invasive Plant Identification
Around 1 in 5 suspected cases turn out to be something else — which is why we offer free photo identification before any paid site survey is needed.
No obligation. Expert advice.
Certified processes and recognised remediation standards

Accepted by RICS surveyors and mortgage providers

After a home perching survey I was informed that Japanese knotweed was found within the property’s grounds and was advised to seek professional advice. I contacted Japanese knotweed expert, they did an extensive search and could not find any Japanese knotweed anywhere on the property. I would totally recommend this company who were honest and professional from start to finish.Posted on Google Ahsan RiazTrustindex verifies that the original source of the review is Google.
