If your child is in hospital for more than 52 weeks
Your child continues to be treated as part of your household for HB (and therefore you continue to get the child personal allowance, family premium, and enhanced disability and disabled child premium if appropriate) if they are in hospital for more than 52 weeks, provided:1Reg 21 HB Regs; reg 21 HB(SPC) Regs •there are exceptional circumstances – eg, they are in hospital and you have no control over the length of their absence. This is an example given in the law; and
•the absence is unlikely to be substantially more than 52 weeks.
Note: if the only reason you are exempt from the benefit cap (see here) is because a child for whom you are responsible is entitled to CDP or ADP, this exemption will end if the child no longer counts as part of your household.2Regs 75A and 75F HB Regs
