Robert Mitchell CSJK

- PCA certified surveyor

I’m an examiner at the Property Care Association  and a PCA certified surveyor in Japanese knotweed (distinction). As well as knotweed, I have a strong reputation for my knowledge and experience of other non-native and native invasive weeds, including those of danger to humans and livestock.

I’m active in supporting the development of the profession, having organised, and been involved with the PCA annual conferences (chairman of conference in 2018) , and continue to assist with developing training materials on an ongoing basis. I have made a short training video for the PCA.

No need to worry.

I’m an independent nationwide knotweed specialist and PCA certified surveyor, expertly trained and can help find a suitable control option for your circumstances.
