I think using the term EGNOS might be confusing. As I understand it SBAS APV is supported by EGNOS and IAPs designed to use this augmentation are coded LPV on the plate.
So beerdrinker was right to name Alderney and mention SOU as next in line, but the fact that the UK have other RNAV (GNSS) IAPs to non precision MDH(A) doesn't detract from the truth of his answer.
I'm sure you are aware of ACCEPTA. The UK is working closely with the managers of this project to realise several new approaches to an LPV minima.
