You'll get more money as you'll get the child element. Other payments could be: - rent depending on your circumstances. - Carers - if you care for someone for more than 30hrs a week and they're in receipt of qualifying benefits. LCWRA - if you have a health condition that prevent you from working and have been through the health process to confirm and have been awarded this (have to submit fitnotes and have health assessment before establishing if you are entitled) Can check out entitledto.co.uk to see. Also CAB are good at making sure you are getting what you are entitled to.
