Problems with primary to secondary school transfer?

was wondering if anybody could help me some help and advice please we are currently in the process of finalising a house move which will be completed on the 4th July 2011. The problem is my daughter doesnt finish primary school until 26th July 2011 and doesnt start Secondary school until 5th September 2011 my query is can i keep her off for the few weeks of her moving and school ending in July as i really cant afford or want to put her through the stress and upset of starting a new school for 2 weeks then having to start another one in september plus the cost would be extreme having to pay out for 2 uniforms within weeks of each other. Please if anybody can help i would be extremly grateful....
