We blend experience, technology, and industry best practices to provide the best Japanese knotweed treatment experience in the UK.

PBA has been successfully carrying out Japanese knotweed herbicide treatment for over two decades, providing customers with the ultimate service.


We are ISO9001 quality assured and only use accredited technicians who complete professional treatment reports as standard.

Furthermore, all of this is underpinned by 10-year insurance-backed guarantees.

Our free virtual surveys have been designed to provide you with immediate peace of mind, to allow you to act quickly, and find out from an industry expert the extent of your problem before getting an indication of price.

During the virtual survey, you will use your smartphone to show us your Japanese knotweed; in effect, you will be our eyes on the ground! Don’t worry; we’ve done this for a while and will help you overcome any technical issues.

N.B. Our free virtual surveys aren’t a replacement for a professional knotweed survey visit. However, they do enable us to quickly evaluate the impact of knotweed, propose an appropriate course of action and determine a potential budget cost.
