Japanese Knotweed Resources


Our expert team can help you identify Japanese knotweed and other invasive plants, before it’s too late.

Japanese knotweed can be mistakenly identified as other similar plants, such as Russian vine or Himalayan Honeysuckle, but it can cause a lot more damage than these plants.

If you spot Japanese knotweed, we recommend leaving it undisturbed, and getting in touch with us to confirm your diagnosis and make a start on the removal and management process.

Due to Japanese Knotweed’s aggressive regrowth when mishandled or disposed of improperly, Japanese Knotweed is governed by strict laws and guidelines which determine the way in which it should be treated and disposed of in the UK.

Failure to use a licensed operative such as Japanese Knotweed Specialists could leave you liable to prosecution should you be in breach of numerous codes of practise, including the risk of receiving an Anti Social Behaviour Order.

Knotweed & mortgages

With a large number of lenders and banks refusing to lend if there is Japanese Knotweed present or close to the subject property (especially within 7m), it can be difficult to secure lending or a sale.

Here at Japanese Knotweed Specialists, we provide a solution to help you buy, sell, or remortgage your property. Since mortgage lenders are wary of offering mortgages on properties with Japanese knotweed, it’s sensible to ensure that action is taken quickly. Never try to tackle the job yourself, as there will always be a risk of regrowth. Instead, our expert team will be able to identify, remove, and manage the knotweed, and provide proof that you can use for your mortgage.
