Hello
I would be grateful if you guys can have a look at this job and suggest what the reasonable course of action is!
We have 3 kids, all school aged – 12, 10 and 4. So they are in school between 9-3.30/4pm give or take. We’ve had a live-in nanny for the last 3 years and pay £465 per week gross (£350 net). Between 9-3pm, I’m relaxed with what she can do with her time – as long as duties are done at some point in the week – children’s washing, tidying up of rooms and playroom, we come home to a clean kitchen, kids have healthy cooked meals. Sometimes she does a food shop (she has the family credit card), picks up uniform, takes them to doctors/dentists, sometimes stays home to take the delivery and helps us with runs to dry cleaners etc. We have a weekly cleaner but she does leave the house tidy for us. Clearly, we need her more during school holidays. The job is a very early start = 6.45 am as DH and I both work in London. Finish is around the same 6.45pm. So a long day, but with no kids for the core hours. We live in the Southeast. Her living area is separate from the main house so she has her privacy. Hopefully, that paints a picture?
She is now thinking of moving out and she did mention that maybe I don’t need a FT nanny as such. We are keen to keep her on as the task of trying to find an early morning/after school nanny + holidays is a bit daunting. What is a reasonable uplift? Would you do these hours for £450 net per week - i.e. £632 gross per week (nannytax calculator)? Am I being silly not trying to look for another live-in nanny or a different arrangement? (if the latter, what?? – the youngest is only 4 so I don’t really want an au pair). I’m trying to keep things as simple as possible but thought I would get soundings (to see if I should pull my finger out). We can afford to pay the uplift (don't want to offer much more), so whilst a consideration, not the main point. I’m just wondering if this is her saying her heart isn’t in it anymore and wants younger kids to look after. I know for some nannies, they don't really want our arrangement 
Thank you.
