When should I get JustCheck™ 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 certain there is no knotweed present, including rhizome beneath the ground or on adjoining property within 3 metres of the boundary. Those who provide false information risk lengthy and expensive claims for misrepresentation. Answering “Not known” pushes the risk onto a buyer, who is then left asking questions.

The solution? 

JustCheck™ –  Japanese knotweed protection can be used 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.

JustCheck™ -
knotweed protection 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.

Beware of misrepresentation

If you know that your property has Japanese knotweed, you must tell potential buyers. Not doing so could result in legal action, as seen in a prominent case in Raynes Park. In that case, a homeowner successfully sued the seller for misrepresentation after discovering knotweed behind a shed in the garden after buying the property. This failure to disclose led to damages and costs of £230,000, reflecting the reduced value of the property.

Proving there is no knotweed on the property can be difficult for sellers, especially since it can remain hidden underground for many years without growing. On the other hand, buyers might easily spot its presence soon after purchasing. Experienced conveyancers typically advise clients to only confirm the absence of knotweed if they are absolutely certain, suggesting it’s safer to say “Not known.”

For sellers wanting to reassure buyers further, there’s the option of obtaining JustCheck™ protection. This involves getting a warranty that guarantees no knotweed is present on the property. This coverage extends to any emergence of the plant after the sale, helping to ease uncertainties and ensure a smooth transaction process.
