Registration takes about 2-3 months and think involves more than just crb check (first aid training comes to Mind and need some relevant qualificiation or experience). Costs of registration (about £100) first aid course (£50 up depending on what needed) need to be added in.
Do you need OFSTED registration to use WTC as with childcare vouchers? If so, the process from filling out the initial form online can take around 3 months, including an enhanced CRB check. She will need to provide a first aid certificate and I think have minimum level 2 NVQ in childcare or equivalent. You will be registering for the voluntary part of the childcare register.
I don't know about tax etc - sorry - but would imagine you'd have to process a proper payroll in order to use the childcare vouchers.
yes it is, I earn £12 per hour and my other nanny friends earn £15-16.50 per hour, but if she's agreed to it fine good on you, it's just that if you're expecting her to go through the ofsted registration (which is quite a big faff) and hold on to her then you might want to be a bit more generous.
I do agree with you bubaluchy, but this is her first nannying job, she has previously worked in a school, so therefore I thought you would start at the bottom of the pay scale, so to speak. The more experience she would get the more money she would then earn.
Pension - that I believe is consider as income for tax purposes. You will need to look that up, find out what the situation is, but I think the pension comes off the personal tax allowance, so reducing the amount that can be earned taxfree. I'm not currently able to research it, so I'm only guessing at the moment due to my having had an issue with having a pension and a job at the same time.
