I'm afraid they aren't published in the UK.
But a word of caution - I would recommend you buying it in a set, or getting the individuals hard bound

I bought them individually and already two of them have no binding coil left

Which ones are you/were you going to learn?
Have you heard them being played?
After seeing Vanessa Latarche play 'Fascinating Rhythm' on the ABRSM diploma video, I so enjoyed the piece that I now have the set of etudes, and I'm learning 5 of them for my BA dissertation this march

Let me know if you're also learning them. I know of a few concert pianists who use them as Encores.
