All our Japanese knotweed surveys are conducted by one of our CSJK qualified surveyors. Our expert surveys will find and record any visible signs of Japanese knotweed on, or affecting the property. Japanese knotweed is not to be ignored. It is a highly invasive species, and if left unchecked can cause damage to your property and even lead to fines and legal issues. Take control and book a survey.

IDENTIFICATION & SURVEY

If you suspect that you have Japanese knotweed on your property or land, we run a completely free identification service. You can just send in a couple of good quality pictures of the suspected plant and our friendly and helpful experts will review them and respond to you with confirmation.

Having Japanese knotweed on your property can be anxiety inducing. We know. Whether it’s a small knotweed stand or a large infestation near commercial services (such as in the picture), it’s a problem we can resolve for you. Having a survey will give you the information you need to know and provide us with information we need in order to provide a quote. The survey findings are detailed within a report that will go on to form a documented Knotweed Management Plan.

HOMEOWNERS survey

If you are selling or buying a property that you suspect is affected by Japanese knotweed, it’s advisable to get a pre-purchase or pre-sale survey of the property. Getting a survey will enable you to fully understand the level of infestation that is on the property. If you’re buying, it will enable you to make an informed decision, and if you are selling – you can have a Knotweed Management Plan (KMP) in place.

A Knotweed Management Plan (KMP) is a prerequisite for house buying and selling where the property in question is affected by Japanese knotweed, as most mortgage lenders will insist on proof that there is a KMP in place. The Environment Agency also states that once you find Japanese knotweed on a development site, it is essential that you set up some form of KMP.

Japanese knotweed LEGALITIES

Japanese knotweed is NOT to be ignored. The information on this page is intended to give you some guidance on the laws relating to Japanese knotweed.

Japanese knotweed and the law

why a survey is important

In some cases, the presence of Japanese knotweed may be subject to a legal dispute such as encroachment (private nuisance), misrepresentation or professional negligence. Upon surveying our expert surveyors can provide an assessment that can be used in evidence for such claims.

We also conduct surveys on the completion of works to record the completed situation. This happens typically on construction sites where knotweed waste has been buried or relocated. The survey will show the position of the waste on-site. Such records are important for future management and use of the property and on development sites are included in the Operational and Maintenance Manuals.

To help understand and categorise the level of risk that the knotweed presents to the property, the Royal Institution of Chartered Surveyors (RICS) have created a “risk” table. The level of risk is defined by the proximity of the knotweed to the habitable area or the property boundary and if any structural damage has been caused.
