The NHS doesn’t provide carers unless people need specific nursing care Allsorts, I think your friend is thinking about Local Authority carers, who are often now Agency staff contracted by the LAs to help people get up or to bed?
My Mum has a LA carer in the morning (20 minute call) to help her get up and washed, and a one hour private lunchtime carer to cook lunch and prepare the evening meal which Mum and Dad then sort for themselves. They also have a cleaner, who is there two mornings a week, they are both in their mid nineties. I’d agree on the cost with what others have said.
I’d advise your friend to think carefully about her needs before committing to paying for two hours a day in the morning only, and then discuss her needs with a couple of agencies - not all care agencies provide carers who will clean and shop as well as provide personal care, so it’s really important to define exactly what you’re looking for first.
