Hi RevKate
As a first step, you may wish to familiarise yourself with the NHS Guidelines of Continuing Healthcare (CHC) via this link:
https://www.gov.uk/government/publi...inuing-healthcare-and-nhs-funded-nursing-care
You'll see (para 95 of the "Guidelines" document) that the decision process to determine eligibility should not normally exceed 28 days. This is so that the individual's healthcare and nursing needs are reasonably "current" when the decision is made. But this particular clock only starts ticking when the "checklist" (see link for more info) process actually starts.
But I know from first hand experience certain Clinical Commissioning Groups (used to be called Primary Care Trusts) don't adhere to the NHS' own guidelines particularly rigidly, so I recommend you make yourself known and keep chasing the right people, particularly, having read and understood the "Decision Support Tool" (again, via the link), you think your mother would qualify.
Having said that, my local CCG just took a whole year from assessment to deciding to withdraw my mother's eligibility, but that's probably (hopefully!) an example of the NHS at its worst, which I've written about elsewhere on the forum.
Good luck and don't forget there's lots of good advice and experience on here.
