I also work for Sky (different part) and these guidelines seem mostly sensible to me, so much so I may recommend them to my team, with some caveats:
- Have no problem with IDs if they're used correctly for unique items. The cascade should not be an issue.
- Formatting of css and vendor prefixes - these aren't guidelines they're personal preferences. There's no appreciable maintenance benefit for any of them in my opinion. Each to their own.
I am in favour of dashes too, On a big project you might spend literally 100s of hours writing or editing css, using dashes will save you enough time in keystrokes to have a an extra long lunch by the end of it.
