Commercial Japanese Knotweed Removal

If you suspect that you have a Japanese knotweed infestation on a commercial property or development site, then there are legal and financial issues that you need to be aware of.

Early action to treat Japanese knotweed by qualified specialists is essential if you are to avoid excessive remediation costs, potential prosecution, claims for compensation and/or structural damage to buildings and services.


If Japanese knotweed identification occurs early in a construction project it allows a wider range of knotweed treatment options to be considered in order to eradicate it.


Additionally, if knotweed is identified at the due diligence stage of a property transaction, it can allow substantial price reductions to be agreed through negotiations to offset remediation costs.
