What's a no-knotweed report?
A no-knotweed report is a legal document that states that a property is not infested.
Do you need help with planning permission and Japanese Knotweed?
When applying for planning permission for an extension or new build, the planning office will often put in planning conditions.
One of these is that a survey for Japanese knotweed is carried out. Having a Japanese knotweed survey conducted on the site can prove to be invaluable. Japanese knotweed is notorious for devaluing sites. As well this can cause serious structural damage to buildings which may be developed on infested land.
A survey to fulfil the requirement of a Japanese knotweed planning condition would start with a site visit from our PCA qualified surveyor who would fully assess the site and any suspicious plant.
A report would then be prepared which includes the following:
If there is no Japanese knotweed, we would complete a signed letter. This is for the planning officer and your file. The letter confirms that there is no Japanese knotweed on site and allows you to continue with your development.
A no-knotweed report is a legal document that states that a property is not infested.
If Japanese knotweed is found to be present on site, a full management plan would be produced that can be presented directly to your planning officer.
The management plan would include:
The objective of control action ,
An evaluation of control options ,
A detailed control action description,
Criteria for completion,
Advice on preventing spread around/off/on site,
Any costs involved in the eradication of the invasive weed.
All of the management plans we provide include a 10 year insurance backed guarantee and our 10 year company guarantee.
Thus, the most common and preferred treatment method for Japanese Knotweed is a herbicide treatment.
However, the best time for Japanese knotweed to be sprayed is when the plant is actively growing. This is because of the type of herbicide used.
Japanese knotweed excavation and removal usually occurs in the event that there is not enough time to treat using herbicide treatments.
Therefore, removal is the ideal solution.
Alternatively in some instances other methods of treatment can be combined to ensure complete eradication of Japanese knotweed.
For example partcial excavation, burning, temporary bund creation, membranes etc.
