Hi freefee
CB ESA is the same as NS ESA, as you are in the support group then your award is indefinite until you are next reassessed then depending on the out come you will either stay on CB ESA or you will be placed in the work group or found fit for work.
In answer to your question, as long as you stay in the support group then your benefit will not be means tested.
