New inquiry launched: Japanese Knotweed and the built environment

20 November 2018, by Matthew Appleby, Horticulture Week

The House of Commons Science and Technology Committee has launched an inquiry on Japanese knotweed and the built environment.

The Committee said: "Japanese Knotweed is an invasive non-native species with a range of negative environmental effects in the UK. One such effect is in the built environment, in terms of potential damage to buildings and as a nuisance for homeowners and developers. The presence of Japanese Knotweed is known to have an effect on mortgage lending decisions and property valuations, although it can also be effectively managed."

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 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.

The Committee is also interested to hear from the public about their experiences of dealing with Japanese Knotweed, whether as a homeowner, tenant, prospective purchaser or developer for an engagement event in Westminster on Monday 21 January 2019, 5.30pm–7.00pm.

At the event, MPs will be asking participants more about their experience.
