It's as pointless as the paper it's written on.
Yes, it's a qualification, and yes it's one level above A-Levels, but it's not a degree, and if anything, shows you couldn't cope with a degree (if you got it because you decided to drop out after your first year) so is probably worse than just having A-Levels.
No job requires a CertHE. They're all aimed at school leavers (those with A-Levels) or graduates (those with BA/BSc/etc.).
