I have himalayan balsam in the garden and now understand it's a notifiable
weed.

Have a look at www.defra.gov.uk and also at the relevant legislation -
Weeds Act 1959 and the ?Wildlife or ?Wildplant act of ?1981 - ref on
DEFRA site.
AFAIK it's not notifiable - in other words you don't have any duty to
notify anyone that you've got it.
I think your duty only goes as far as making sure you don't let it
escape - either into the wild or on to neighbouring land, depending on
which Act it's covered under.
