Japanese Knotweed Planning Permission

Planning Permission Advice


Planning Permission


On sites where Japanese Knotweed is known to be present, planning conditions are put in place, to prevent the spread of the plant, as it is an offence under the Wildlife and Countryside Act 1981. These conditions need to be adhered to before building can take place.

You may be wondering why this is the case. Japanese Knotweed can significantly devalue buildings and cause structural damages, because of this Japanese Knotweed will affect planning permission. The invasive plant needs to be completely eradicated from the site before your planning permission can be approved.

In order to fulfil this planning condition a site survey needs to be carried out, where a member of our expert team will visit your site and check for any signs of Japanese Knotweed. The PCA surveyor will then be fully equipped to put together a report that details the condition of the site and the extent to the impact of Japanese Knotweed (if any). The report will include:

  • Location

  • Plant location, including a map
