The Economic Impact Of Japanese Knotweed

Knotweed hurts. Left untreated, it can cause significant structural damage to everything from your home’s foundations to driveways, flood defences, and road infrastructure. The scale of these damages obviously has huge implications for the British economy.

In Britain we enjoy a blissful ‘it won’t happen to me’ attitude, but beliefs of this kind are risky, and could end up costing you thousands in the case of a knotweed infestation. Household cases make up over a quarter of recently reported knotweed growths, resulting in widespread damages and costs for everyone involved.

It’s not just residential homes that are affected, either. Over the last few years, the total cost to developments has been a breathtaking £141 million in England alone.

Clearly the presence of Japanese knotweed on your property can seriously affect its value.


The main problem is identification. Identified early, a professional service can remove knotweed in days or weeks. Left to take root, however, the plant is much more difficult to extract. In these cases you are looking at treatment plans lasting from months to years in order to properly eradicate all traces.

People often think they can remove knotweed themselves, like most other plants, but attempts of this kind are dangerous and potentially criminal. For starters, you need a license to dispose of the knotweed waste. Home removal can actually help spread knotweed; improperly disposed of, the plant is capable of regrowing from cuttings as small as 10 millimetres.

Do not attempt to remove Japanese knotweed without the service of trained professionals. Attempting to do so without the proper licensing can leave you liable to prosecution and a substantial fine.
