EasyFriedRice - thanks for that info.
Looks to me that it is Ad-hoc childcare, not childcare which is fixed days, fixed hours. The info says Very Flexible. If someone were to have someone for fixed hours under contract then I feel an HMRC status officer would probably rule that they were an employee - as they would be doing the same thing as a Nanny.
To be self employed the person doing the work would need to show that they worked for numerous different families over a short period of time. That is how I interpret things, though ultimately it would be up to an individual status officer - not the council or anyone else.
IndigoBell - I think the figures you give for nannies are probably just salary, and possibly just the take home salary. There are lots of other costs of employing a nanny, such as Employers NI, the time/cost of running payroll, activities/outings, travel on duty - search my posts for details if you wish to find out more about nanny costs.
Nannies can be a viable option especially if a family has 3 or more children, or if the time that childcare is needed isn't provided by anyone else - nurseries and childminders have opening and closing times, a nanny does the hours they are contracted to do.
Childcare is expensive, yet as a childcare worker if I got a full time job in a nursery in my area, I would be on about 17000. That would not cover my bills - I'm in Surrey.
What is the soluition? A few generations ago people lived near family. These days many of us do not have family living near - is that the change which means parents these days need to use various forms of non-family provided childcare?
