Some encouraging recent research has come to light about a project to introduce certain insects that weaken Japanese Knotweed. These tiny insects (psyllid) have been released into parts of the UK and do not appear to have any adverse affects on native species. More information is available about the project here: http://www.cabi.org/projects/project/32999
There has been other suggestions in the past to link house prices with EPC ratings. One of which was a stamp duty discount for more efficient properties and it was reported that ministers were considering the idea back in March 2016. However, The Lenders Group did admit that any changes like this are hard to implement due to the complexity of lenders’ systems.
