Going rate for part-time nannies in Central London?

[swlondonnanny]

Hi,
I am an experienced nanny / 10 years / and started to look for a part time job / 30- 35 hours a week over 3 - 4 days/.
What is the going rate for this kind of jobs?
Thanks for all your help in advance!

I would expect £80-£120 per day gross. For example, here is a 4-day job in Battersea @ £85 per day Agency posting that job does not state if Gross or Net.

How central?

East London, rates seem to vary between £8 and £10 per hour, at least. Gross.
