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

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.

Would recommend Japanese Knotweed Ltd

Phoned Japanese Knotweed Ltd re concerns about some suspicious weeds in our garden. Got the answer service and left a message. They rang back promptly.
Was asked by Dan to submit a photo for a review. He was polite and spoke clearly and in a professional manner. We received an email the next day to assure us this was not Japanese Knotweed. This procedure was free which is very pleasing. Would highly recommend this company.

An exceptional provider.

Having just moved into a new property at the weekend, you can imagine how urgently I needed an assessment of some concerning plants at the top of the garden. I cannot say how exceptional the swift response was at 9 am on the Monday morning And the level of expertise that was offered. Luke had a wealth of knowledge and outstanding expertise regarding Japanese Knotweed and I received immediate reassurance. The information he was able to offer was extensive and their service can clearly be delivered at any UK location. I would have no hesitation in reaching out to this provider again and particularly because they are professional, measured and clearly have integrity, in addition to encyclopedic knowledge and you feel that they would not wish to do other than work with you honestly and transparently to achieve solutions
