What utter nonsense! You obviously haven't read thegov.uk document properly, and/or don't understand how LPV works. We no longer are involved in the development of EGNOS, and UK companies after July will not have access to the SoL and Data services, which have nothing to do with LPV. So as per the CAA's notice, LPV approaches are unaffected.
I am getting fed up of all the Chicken Littles running around shrieking that the sky is falling....
