Great service

Great service. I just uploaded pictures and they sent me the most welcome news that I didn’t have Japanese Knotweed. Also suggested what it actually is and all completely free.

Panic Over!!

I was really worried that I had recently bought a house that suffered from Knotweed. I sent some pics to Dan, who identified the plants as being a mixture of buddleia, bramble and nettles. His diagnosis instantly put my mind at ease and the process was quick and simple.

Incredible service

Incredible service! AI had incorrectly identified some shoots growing in the garden of a house I have just moved into as being Japanese knotweed. I uploaded some photos to the folks at Japanese Knotweed Ltd, and within minutes I received confirmation to the contrary. An amazingly fast free service that gives valuable peace of mind.

I was scared that I may have Japanese Knotweed in my garden and the price.

The company got in touch with me and I sent some photo's and was very relieved that it was not Japanese Knotweed which has now put my mind at rest.

Thank you very much for your help

Problems resolved

After a series of unanswered emails I resorted to leaving a 2* review for JKL. They have since called to admit where they fell down and to apologise for what happened. I really appreciated this honest response. They have now listened to my feedback and showed genuine care to rectify the situation - thanks Sharon 😊

I rang the company today to see when the representative was going to arrive. (he was 20 minutes late). The lady was a little bit offhand and unhelpful so I told her that. She replied "don't shout at me" but I wasn't shouting. She then put the phone down leaving me talking to no one. I was really surprised. I tried to call back but got an answer phone twice. The representative has still not arrived.
