Himalayan Balsam is not 'notifiable' and is classified as a 'naturalised non-native plant' but invasive.
The legal position is found here https://www.gov.uk/prevent-the-spread-of-harmful-invasive-and-non-native-plants
In summary it says:
Prevent the spread of invasive, non-native plants
You must not plant in the wild or cause certain invasive and non-native plants to grow in the wild. This can include moving contaminated soil or plant cuttings. If you do, you can be fined or sent to prison for up to 2 years.
The most commonly found invasive, non-native plants include:
- Japanese knotweed
- giant hogweed
- Himalayan balsam
- Rhododendron ponticum
- New Zealand pigmyweed (this is banned from sale)
You’re not legally obliged to remove these plants or to control them. However, if you allow Japanese knotweed to grow onto other people’s property you could be prosecuted for causing a private nuisance."
Himalayan balsam is an annual and whilst it is certainly causing real problems on riverbanks it is not going to prevent you from selling your house. I think Iced Herb is getting it confused with Japanese Knotweed.
Hope that helps
