Having worked as a nanny for 10 years ( I'm now a SAHM) the cost in having an experienced,qualified,full time daily nanny would be from ?400-?500 NET a week . Most nannies will always talk in net for their weekly wages and a full day would be from 7.45/8am to 6/6.30 pm.... . With this cost you can sometimes agree 4 babysits a month or one late night if necessary. Most experienced nannies will not clean for you, you don't really have time looking after two children, but I always took responsibility for the children's rooms ,washing and cooking. Also, would you need to put them on your car insurance,petrol and parking permit if needed for the nannies own car ?? just an extra thought. I think the advantage of having a nanny works well for families that have two working parents especially in the winter months, no dragging the kids outside in the cold weather to go to the childminders and if the children are sick the nanny will be at home with them and you can have peace of mind that your children are safe in the home. Hope this helps.
