Reviews
Richard responded to my email asking…
“Richard responded to my email asking for identification from pictures of the plants, immediately. This service is free of charge. All they ask for is a donation to a charity, which is really nice of them. Would definitely recommend them.”
Lovely company
“Lovely company. I am buying a flat in a high risk japanese knotweed area and spotted some suspicious looking shoots in the garden. Emailed photos to Environet who responded super speedily to reassure me it wasn’t knotweed. They asked for a donation to one of their justgiving charities instead of charging a fee for identification which is such a lovely idea!”
I contacted Environet Uk to discuss my concern about Japanese knotweed.
“I was advised how their identification system operated and was asked to send clear photographic images by email, which I did. Within 3 hours, I received a response. Very impressed by the professional manner this was dealt with. Thank you.”
Fantastic identification service!
“Fantastic identification service! I received an email response 1 hour after I sent the company an email with photos. I was advised that the weeds in the photos were not Japanese knotweed which was a huge relief.”

JustCheck™,
knotweed survey complete with warranty
JustCheck™ is a bespoke Japanese knotweed survey, used in cases where a customer is unsure whether or not a property is affected by knotweed and wants greater certainty before completing the TA6 form, which, if answered incorrectly, could leave them exposed to a legal case in the future. JustCheck™ also offers peace of mind to buyers who have received a ‘Not known’ response for Japanese knotweed on the TA6.
Our expert surveyors will check the property for any sign of knotweed, including within 3m of the boundary. As concealment or dormancy following herbicide treatment could result in our experts being unable to identify any Japanese knotweed on a property, our reports also come with a 5-year £20,000 warranty* to cover the cost of treatment in the unlikely event it should later appear.
*Assuming no Japanese knotweed is found or suspected during the JustCheck™ survey


When should I get a JustCheck™ Japanese knotweed survey?
All sellers of residential property are asked to disclose whether their home “is affected by knotweed” when completing the standard TA6 Property Information Form. Since The Law Society changed its guidance in 2020, sellers who answer “No” must be sure there is no knotweed present, including rhizome beneath the ground or on adjoining property within 3 metres of the boundary. Those that provide false information risk lengthy and expensive claims for misrepresentation. You should therefore get a JustCheck™ Japanese knotweed survey if;
- You are selling your home and want to check if Japanese knotweed is present so that you can accurately answer the TA6 form.
- You are buying a property and want to give yourself some peace of mind that it is free of Japanese knotweed.
- You are planning an extension or a self-build and want to check your garden to prevent accidentally building over Japanese knotweed.
Japanese knotweed: beware of misrepresentation
If you know that your property is affected by Japanese knotweed, you must tell a prospective purchaser, otherwise you could find yourself on the wrong side of a costly and very unpleasant lawsuit for misrepresentation. In a well-publicised legal case in Raynes Park, a homebuyer successfully sued their seller when knotweed was found growing behind a shed at the bottom of the garden after they moved in. Damages and costs were awarded to reflect the diminution in the property’s value as a result of the knotweed, costing the seller, who gave false information, £230,000.
For the seller, proving a negative is always fraught with difficulty, even more so for knotweed that can be hidden underground in a dormant state. For the buyer, its easy when the knotweed starts to grow soon after taking ownership. Good conveyancers will advise their clients to only answer “No” if absolutely certain, the safer option being a “Not known” answer. For the seller that wants to provide their buyer with more reassurance, a JustCheck™ survey, with the warranty assigned to the new owner, can eliminate the uncertainty and allow the sale to proceed unhindered.
