Step 1 of 4



A Japanese knotweed survey and report is essential when selling or buying a UK property that is affected by Japanese knotweed

A Japanese knotweed survey will provide formal identification of this non-native invasive plant species. It will also provide an accurate record of where the knotweed is located, the extent of the risk zones and a remedial methodology for control or removal.


Looking for a Japanese knotweed specialist? As we are a Property Care Association (PCA) members, accredited Knotweed Remediation Specialists as recommended by The RICS (The Royal Institute of Chartered Surveyors) to undertake and complete these surveys.



Free virtual surveys and knotweed surveys

At PBA Solutions, we offer a free, virtual knotweed survey where we provide you with meaningful advice, identify your needs and outline control costs. This allows us to identify the best course of action, which normally involves completing a paid Japanese Knotweed Survey and providing either a ‘Knotweed Management Plan’ (KMP), or a ‘findings report’. Then we can turn up at your property and carry out a combined survey and first treatment, saving you the cost of two separate visits.








What should I expect in a Knotweed Management Plan?

  • Survey findings 
  • Proposals for treatment 
  • A scale plan drawing identifying location of the knotweed (in relation to buildings)


The objective of the KMP is to clearly document the nature of the problem for mortgage lenders, prospective buyers, and their solicitors. Naturally, our management plans must be paid for since they are designed to become material documents within a property sale. We, therefore, urge people to be cautious of companies offering free management plans since these would not necessarily be suitable as a document of reliance. 


A lot of companies subsidise Knotweed Management Plans by making their customers pay a large one-off fee for the whole service including treatment and guarantee fees. At PBA our ethos is to offer a flexible approach where our clients only pay for what they need
