Book a Survey

A Japanese Knotweed survey is a thorough, professional inspection of your property and its surrounding grounds carried out by a trained surveyor. It is designed to identify whether Japanese Knotweed is present, to assess the extent and maturity of any infestation, and to evaluate the risk it poses to buildings, boundaries and the wider area. Following the inspection you receive a clear, evidence-based report together with a recommended management or eradication plan, so you know exactly what you are dealing with and what steps should follow.

If Japanese Knotweed is suspected on or near your property, a formal survey is often a requirement rather than a luxury. Mortgage lenders, conveyancers, buyers and insurers frequently ask for a specialist report before proceeding with a transaction or policy. Beyond satisfying these requirements, a survey gives you an accurate, expert identification (rather than a guess), protects the value and saleability of your property, and provides documented evidence that can be shared with solicitors, surveyors and prospective buyers with confidence.

The cost of a survey varies depending on the size and type of property, its location, and the level of detail required. At Japanese Knotweed Agency our surveys are competitively priced and represent strong value because they include a detailed, documented report with photographs, mapping and clear recommendations — rather than a simple visual opinion. We will confirm the fee for your specific circumstances before booking, with no obligation, so you know exactly what you are paying for upfront.

In most cases we can arrange a survey within a few working days of your enquiry. Where time is critical — for example a property sale or purchase that is nearing exchange, or a lender condition that must be discharged quickly — we offer priority appointments to keep your transaction moving. Simply let us know your deadline when booking and we will do everything we can to meet it.

Your report is comprehensive and evidence-based. It includes a clear identification of any Japanese Knotweed found, high-resolution photographs, a measured risk assessment, a site plan or map showing the affected area, an estimate of the infestation's scale and likely age, and a tailored management or eradication plan with recommended next steps. Where required we can also include a formal Japanese Knotweed Management Plan (JKMP) suitable for lenders and solicitors, and a quotation for our non-chemical thermo-electric eradication.

Yes. Japanese Knotweed Agency operates across the UK and Ireland with a network of local surveyors who understand regional conditions, native species variations and the specific requirements of different lenders and local authorities. Because we cover the whole country, we can usually attend your property promptly regardless of where it is located, and you benefit from a single, consistent national standard of reporting and advice.

Absolutely. If Knotweed is confirmed, the report will set out the scale of the infestation, its estimated age and vigour, the risk it presents to structures and boundaries, and the realistic treatment options available — including our chemical-free thermo-electric eradication, excavation and removal, and root barrier installation. We explain the advantages and limitations of each approach so you can make an informed decision, with a clear quotation and timeline for any works you choose to instruct.

If no Knotweed is present, that is good news — and you still receive a formal confirmation report. This documents the inspection and its findings, giving you written reassurance that can be presented to buyers, solicitors, lenders or insurers to satisfy conditions and remove doubt from a transaction. It can be particularly valuable during a sale or remortgage where knotweed has been raised as a concern but is not actually present.

Yes. Our surveys and reports are produced to a standard recognised by mortgage lenders, buyers, conveyancers and solicitors across the UK. Where a lender requires a formal Japanese Knotweed Management Plan (JKMP) or an insurance-backed guarantee, we can provide these as part of the process. Our aim is to remove the knotweed question as a barrier to your mortgage or property transaction as smoothly as possible.
