FAQ - P35 in Hampshire
My architect or developer says I need Japanese Knotweed identification and removal — what is it?
It is a professional plan that identifies knotweed and sets out safe removal or containment measures. The plan ensures your Staffordshire development complies with legal requirements and avoids future property damage.
Do I always need a site survey before submitting a removal plan?
Yes. A detailed survey is required to accurately map infestations and plan safe removal or containment.
Can small properties or extensions be affected?
Yes. Even minor developments may require a removal plan if knotweed is present. Hampshire local authorities may impose conditions to protect neighbouring properties and ensure safe development.
If I already have planning permission in Hampshire, why am I now being asked for a Japanese Knotweed plan?
This usually indicates that your site has confirmed or suspected knotweed, and the council requires evidence of safe management. Construction may be delayed until the plan is approved.

How long does it take to prepare a Japanese Knotweed removal plan in Hampshire?
Most plans can be prepared within 10 working days, depending on site size and complexity. Larger or phased developments may require additional time
Is a removal plan different from a site survey?
