FAQ - P35 in Surrey
My architect or developer says I need a Japanese Knotweed identification and removal plan — what does this involved?
It is a specialist report that confirms whether Japanese Knotweed is present and sets out approved methods for treatment, control, or removal. The plan helps ensure your Surrey development meets planning and environmental requirements while reducing long-term risk to the property.
Is a site survey mandatory before a Japanese Knotweed removal plan can be produced?
Yes. A professional site survey is essential to locate, map, and assess the extent of any knotweed. Without accurate survey data, a compliant and effective removal plan cannot be prepared.
Can Japanese Knotweed affect small developments or home extensions?
Yes. Even modest projects such as extensions, garden works, or single dwellings may require a knotweed plan if the plant is present. Surrey councils may apply planning conditions to protect neighbouring land and infrastructure.
I already have planning permission in Surrey — why is a Japanese Knotweed plan now required?
This usually indicates that Japanese Knotweed has been identified or is suspected on or near the site. The local authority requires assurance that it will be safely managed before works proceed, which may otherwise be delayed.
How long does it take to prepare a Japanese Knotweed removal plan in Surrey?
Most removal plans can be completed within around 10 working days, depending on site size, access, and infestation levels. Larger or multi-phase developments may take longer.
What is the difference between a Japanese Knotweed survey and a removal plan?
The survey confirms the presence, location, and extent of knotweed. The removal plan sets out the method of treatment, timescales, monitoring, and compliance measures required to manage or eradicate it safely.
