I'm not sure it is an ICAO recommendation or requirement to use 'degrees' after a heading so I don't believe the controller was incorrect. Please feel free to correct me but I am under the impression that this is a UK-only habit and that is why controllers across the rest of the world don't use the suffix 'degrees'?
I maintain that the overly verbose 'when established localizer blah blah blah' should have been read back as 'cleared ILS'. This is the standard clearance that the controller gave and this is what they would have been expecting to hear back. The pilot reading back their own super extended version to a person who may not have perfect English outside of standard phrases isn't a good idea in my book.
As I said, I am in favour of everyone using standard English on the RT to aid SA but it should be standard and us Brits shouldn't be making it unnecessarily verbose.
PS when you say 'edited your post' was you referring to me - as I haven't edited anything?!?
