i think you may be getting your terminology mixed up because colleges in the UK are FE institutions not HE institutions. In general, anything below university level is not HE, it is FE. A levels or the equivalent are considered Post-16 FE courses, so if you are doing a course that gives you qualifications equivalent to A levels to get into university, it will most likely be only FE level, rather than HE.
I'm not sure about foundation years-I'm writing this on my kindle so i can't look it up right now.
