Terpe - I have been doing a lot of research since your last reply and your last paragraph is of great interest to me.
Could I ask you to have a quick look at this PDF (which is from the Northern Ireland Council for Ethnic Minorities)

On the face of it this document seems to solve all my worries! (and fits my case)

They say:
"Tier 2 migrants applying to settle in the UK prior to 6 April 2016........For senior care workers who have only held a Tier 2 visa, this will be £7.80 per hour. Those who entered on a work permit and then switched to Tier 2 will fall under the transitional arrangements and will need to be paid a salary of £7.02 per hour."

I am trying to get my head round this. Why would the Home Office be turning down ILR for Senior Carers who started on a work permit and earn more than £7.02, only to then allow the ILR on appeal? Is it just a lottery or is there something different about the applications that fail? Maybe the ones that failed were less than £7.02. Surely the timeline would mean that everybody who is applying for ILR just now would have started out on a Work Permit? Is that right?

If there is anyone else reading this who has had success or failure for a Senior Carer earning less than 7.80 but more then 7.02 please chip in and offer and thoughts that you have. Thank you.

If it is a Lottery....I think I am going to have a nervous breakdown.
