Hi Ryan,
If you don't feel like you're able to meet the 16 hours, you may have to start presenting fitnotes to UC via your journal, and ask to be assessed with a UC50 form. After the assessment, they'll usually put you in 1 of 3 groups - which are normal, LCW and LCWRA - although citizens advice is now saying 4 groups - so im not sure which relates to which, but you can see more about it via this link:
