    Three days into moving into my new home, August 2018 I found Japanese Knotweed growing in the garden. Angry and upset the Surveyor had not done their paid job properly I contacted Cobley Solicitors. They calmly and professionally advised me of the process moving forward.


    Eight months later my compensation claim was awarded. Knotweed being dealt with and I feel much happier and reassured. I recommend Cobleys to anyone with a Japanese Knotweed problem. It is true I am so much happier now all dealt with.


    Can Our No-Win No-Fee Japanese Knotweed Solicitors Help You win a Japanese knotweed claim?

    Can you make a Japanese knotweed claim?

    If a neighbour has failed to comply with their legal responsibility to prevent their Japanese knotweed from spreading to your property, then you may be able to make a Japanese knotweed claim. When purchasing a new property, if the seller has informed you that knotweed is not present when in fact it is, then you also may be entitled to make a claim and receive compensation from the seller.

    Japanese knotweed in neighbours garden?

    It’s not illegal to allow Japanese knotweed to grow on your land, however, there are laws condemning those that allow an invasive plant to cross from your property onto another’s land.

    Both the Anti-social Behaviour Crime and Policing Act 2014, as well as the Environmental Protection Act 1990 and Wildlife and Countryside Act 1981 have been amended over the years to include Japanese knotweed which can cut a house value down by as much as 10%.

    In the event of a neighbour (whether it be an individual or an organisation) allows knotweed to leave their land and enter yours, they will be liable for the costs incurred of you removing the infestation.

    A precedent was laid down for this in 2018. It’s important to note that before a claim can be made for the costs of removal, you will need to formally notify your neighbour of the presence of the knotweed.

    Find out more about the legal implication of having Japanese knotweed by reading our Japanese knotweed UK law guide.

    Bought a house with Japanese knotweed?

    Home Buyer Surveys come in a variety of formats and give prospective buyers the opportunity to learn more about a property that they are considering to buy.

    A correctly undertaken survey should highlight areas of the property that may need work completed, including the presence of knotweed.

    The resultant survey is a legally binding document that carries serious legal implications if incorrectly completed by the surveyor.

    In the case where a surveyor misses Japanese knotweed on the property and you decide to make the purchase, then you may be able to pursue a claim to cover the costs of removing the Japanese knotweed from your land.

    TA6 form incorrectly completed by the property owner?

    Taking the form of a simple questionnaire, the TA6 property form is an 18-page document that is filled out by the property owner and given to prospective buyers.

    The questionnaire includes questions relating to the boundaries of the property, any disputes or complaints relating to the property, as well as the presence of knotweed.

    In the case where a property owner lies about Japanese knotweed affecting the property, you should be able to claim against that property owner.

    When pursuing this kind of claim it’s important that you have a way to contact the previous owner.

    Japanese Knotweed Claims FAQs

    What is Japanese knotweed?

    Japanese knotweed (also known as Reynoutria Japonica) is a large species of herbaceous perennial plant of the knotweed and buckwheat family, Polygonaceae. Also commonly known as Asian knotweed, Japanese knotweed is native to Japan, China, and Korea, but has been prevalent in the UK since 1850 when Phillip von Siebold brought over a single female plant.

    Since then, Japanese knotweed has caused dismay for countless homeowners across Europe and North America, as the plant is known for its rapid growth and ability to push through tarmac, concrete and drains – causing severe structural and financial damage to property.

    Why is Japanese knotweed a problem?

    A 2018 study by global infrastructure service firm AECOM and the University of Leeds found there’s “nothing to suggest that Japanese knotweed causes significant damage to buildings” however, co-author Dr Karen bacon of Leeds University stated that “[it] is capable of damaging built structures”.

    This potential to damage buildings is still an issue amongst mortgages lenders that are cautious of the weed draining the property’s value. Even a minor knotweed infestation can knock thousands of pounds of the value of your home and could stop you from being able to sell it.

    The government’s environmental agency states that “you must prevent Japanese knotweed on your land spreading”. Because of this, many Japanese knotweed experts recommend taking a proactive approach by contacting established professionals that can help you identify and remove your knotweed.

    Experienced in all areas of Japanese knotweed identification, removal, and litigation, we are here to help you every step of the way. Call today to find out how we can help with your knotweed invasion – you could be able to recover costs even if you’ve already dealt with your knotweed problem.

    Should you buy a house with Japanese knotweed?

    Buying a house with a Japanese knotweed infestation means you are purchasing a property that requires years’ worth of work that could cost thousands of pounds. A Japanese knotweed infestation can cause the property’s value to fall by 10%. Unfortunately, some property sellers lie about Japanese knotweed, making it crucial to have a cautious approach when considering purchasing a property with knotweed present.

    How do you identify Japanese knotweed?

    Japanese knotweed is found in nearly every 10 square kilometres of the UK. It can spread rapidly and can cause serious damage to the infrastructure of your home, growing through walls, drains and paving.

    Even a minor knotweed infestation can knock thousands of pounds off the value of your home and could stop it from being sold altogether. We can help identify your Japanese knotweed problem so that you can mitigate potential financial losses, or claim compensation from the responsible party.

    Can you claim for Japanese knotweed?

    If Japanese knotweed spreads onto your property due to a negligent neighbour failing to control the plant on their land, you should be able to claim compensation against them.
