How much does it cost to remove Japanese Knotweed?

The cost of Japanese Knotweed removal will depend on factors for example the scale of your infestation, the location, your property type, how soon you need the knotweed removed, as well as what the future plans for the land are. In a lot of cases, herbicide treatments can be effective in eradicating Knotweed and are a cost effective solution. But if there are plans for the property to be developed and soil disturbed, it’s likely an excavation would be required, which is a higher cost in removing your Knotweed, but is a quicker solution. As a result, Japanese Knotweed treatment costs will vary.

Legal cost of Japanese Knotweed

It’s not against the law to have Japanese Knotweed growing on your property, however if you fail to control the growth of the plant and allow it to spread to adjoining land or neighbouring properties, you are breaking the law. You could receive an ASBO and a fine of up to £2,500, as well as being liable for the cost of removing the plant from the property you have allowed it to spread to.

The penalties are quite serious due to Japanese Knotweed’s damaging nature and ability to cause thousands of pounds of damage in treating the weed but also in the devaluation of the property or land.
