Hello Nigel.
The system you desire seems to be a suitable one.
The 46cm dish size is more suited to UK use, for the 28 Degrees East Bird (Sky/Freesat)
Obviously, you need a clear unobstructed view to the required Satellite.
This weekend I moved my manual dish to 9 Degrees East to check reception, I have a clear view to birds to the West, as well as greater then 28 Degrees East.
If you go for the PAPSA PLUS, you pay a bit extra (96 GBP) to have 11 Pre-Programmed Satellites compared to just the Sky/Freesat for the basic system.
I have no personal experience with these systems though.
Kind regards James
