My wife gets State Pension,DLA higher level and Pension Credit. I get Carers Allowance and have a private pension of £300pm. At present we get HB and CTB. When I get the New State Pension,later this year how will it work with me on the New State Pension and my wife on the Old one ? I understand I will no longer actually get CA but have still an underlying CA right but how will PC,HB and CTB work ?.
