We were very concerned when we were told there was a possibility of Japanese Knotweed in our garden so I sent of an email to Japanese Knotweed Ltd including several photos and I received a response very quickly advising it was not JK. Very happy with the service and fast reply. Thank you.

Knotweed or not?

I had a suspicious climbing plant spreading rapidly through my border and wanted to ensure it wasn’t Japanese Knotweed. I sent a picture and my concern was answered promptly and efficiently confirming that it was in fact bindweed which put my mind at ease.

Quick and free identification service

I used Japanese Knotweed Ltd's free identification service. I sent a few photos in the evening and was impressed to receive a response by midday the following day. I'm pleased to say the plant I'd found in my garden was not Japanese knotweed, but if it had been, this company would have been my first port of call to get it sorted, as they clearly have excellent customer service.

Used before home purchase. Efficient, timely, terrific service. Even helped reassure me post moving in when I saw a small shoot of something.

Japanese knotweed?

I submitted five photos of the "suspected" dreaded Japanese knotweed. Within 15 minutes I received an answer "NOT Japanese knotweed" PHEW! Brilliant response time, thank you.

Very disappointing service.

We are paying a substantial amount of money for this service, so I expected a professional and reliable approach.

We had a site visit booked for 19 May 2025, which was cancelled at the last minute. We rearranged, made time again, and today the visit has been cancelled again at short notice.

This is not acceptable, especially when customers have to arrange access, leave their own work, and manage their diary around confirmed appointments.

I understand staff sickness and unforeseen issues happen, but when the same customer has already had one appointment cancelled, there should be a proper contingency plan in place.

This has caused wasted time, inconvenience, and disruption to my business day. For the amount being paid, the level of service has fallen well below what I would expect.

I have now asked for this to be escalated as a formal complaint.

Quick assurance not Japanese Knotweed

I saw a plant with heart shaped leaves and red stems in my back garden.  I was concerned it was Japanese Knotweed. Thankfully I found this service who advised, from the photos I sent, that it was not Japanese Knotweed. I really appreciated their assurance and quick response.
