The Science and Technology Committee intends to hold a one-off oral evidence session in early 2019 with relevant experts, specifically to explore the science behind the effects of Japanese Knotweed on the built environment.

To inform that session, written submissions are invited on the following issues by Monday 31 December:

  • What scientific evidence exists on the effects of Japanese Knotweed on the built environment;
  • How the presence of Japanese Knotweed in the UK affects mortgage lending decisions and property valuations;
  • Whether mortgage lending decisions relating to the presence of Japanese Knotweed are currently based on sound scientific evidence of its effects on the built environment; and
  • What guidance for the sector currently exists, the impact of existing legislation, and how else evidence-based responses to the presence of Japanese Knotweed can be encouraged.

You can submit written evidence through the Japanese Knotweed and the built environment inquiry page.
