Japanese Knotweed London
Since its introduction to London as an ornamental plant, Japanese knotweed is now indisputably the UK’s most aggressive, destructive and invasive plant according to the Environment Agency. Japanese knotweed can cause damage to property and is very difficult to control once established. It is listed under schedule 9 of the Wildlife and Countryside Act 1981.
Prior to the London 2012 Olympics, approximately 10 acres of Japanese knotweed was removed from the Olympic Park development site and its surrounding areas. These works took approximately four years, incurring Japanese knotweed removal costs of around £70 million. Since then we’ve been eradicating tonnes of knotweed from London properties, both residential and commercial.
Japanese Knotweed Survey London
If you are selling or buying a property in London and think (or have been advised) that it could have Japanese knotweed, we recommend you instruct a knotweed survey. Failure to control the growth of knotweed can lead to legal action for homeowners. Additionally, if it is identified and dealt with promptly, the cost of removing Japanese knotweed can be kept to a minimum. We offer free* Japanese knotweed surveys, unless we find the property is not affected by Japanese knotweed, when there is a charge of £250+VAT.
After surveying your property or site, we provide you with a Knotweed Management Plan (KMP) which provides our recommendations for how your Japanese knotweed problem is resolved. This could involve a herbicide treatment programme, or complete removal via excavation – but we’ll talk through all options with you so you can make the best informed decision.
Japanese Knotweed Control London
A treatment programme involves methodical and carefully managed knotweed treatments, where the correct use of chemical over a sustained period of time will exhaust the plant and prevent the spread of knotweed. In turn, this will remove the risk of damage being caused to the property during the treatment period.
Japanese Knotweed Eradication London
Excavation provides complete Japanese knotweed removal, where the knotweed affected soils are removed and a root barrier is installed to prevent encroachment of knotweed from neighbouring properties.
Japanese Knotweed Removal Costs, London
The cost to get rid of Japanese knotweed varies, depending on whether the land requires excavating or if a simple glyphosate-based herbicide treatment programme will suffice. However, herbicide treatment can vary in cost, depending on the size of the knotweed infestation.
Excavation could cost thousands of pounds. However, as knotweed specialists, we work with you to reduce your cost of removing this invasive plant, with minimal waste going to landfill.
