The Scops document has ONE line on tapeworms - if they would a significant problem in the UK it would have been discussed at greater length I am sure.
Agnes C Winter in her book "The sheepkeeper's veterinary handbook" actually says: ".... by the time you see the segments (in the faeces) the lambs are begining to develop their own immunity, causing the worms to be expelled." (page 122).
As far as I am aware Praziquantel is not generally available (for food producing animals), but I have not checked this with my vet (He only recommended Panacur). If it is - has anyone used it, what's the commercial name (the dog version is Drontal), and how effective is it?
Also given the wide resistance to Panacur I am not sure how effective it is anymore against tapeworms, but for example my local vet lab, who analyse my wormcount samples are not worried by tapeworm (in this case in one of my goats actually!) at all... I treated my nanny goat with the correct (goat) dose of Panacur, but tapeworm is still happily present - she is actually not bothered by it either!
If someone knows a bit more about the life cycle of a tapeworm, and how it moves from animal to animal (in the absence of dogs eating sheeps heads and then doing their business in the sheep field), danger periods etc I would love to hear about it. Just worrying a bit for my goat, as goats and sheep have different levels of immunity/tolerance to worms.
