Anyone know if there is a ceiling on the amount you can claim for childcare costs when mobilised? My wife is a nurse and works shifts i.e. 07:00 to 20:00 and 18:00 to 02:00 including weekends. This means I need a carer that can do long unsocial hours ( local Nurseries not interested due to weird shift times ) and I have been quoted Â£300 per week ( for 40 hours mostly after 6pm and weekends looking after a 14 month old ) ! Is this reasonable?
