There are special rules if you are aged 16 or 17 and one of the following applies to your situation:
You have been looked after by a local authority for at least 13 weeks since the age of 14 and you left care on or after your 16th birthday. The 13 weeks do not have to be continual (but short-term, pre-planned placements in care may not count towards the 13 weeks)
You were in hospital, a remand centre or a young offenders (or similar) institution when you became 16, and immediately before then you had been looked after by a local authority for at least 13 weeks since your 14th birthday.
If you fall under these special rules, even if you would otherwise meet all the qualifying conditions for the benefit, you will not be able to claim:
No one else (e.g. a parent/guardian) can receive any extra money in their benefits for you either.
This is because social services have the responsibility for meeting your needs for maintenance, accommodation and support and so you are excluded from receiving benefits which cover the same things. However, you are not prevented from claiming any other benefits which may apply to you.
Even if you fall under these special rules, you are not excluded from claiming Income Support or income-based Jobseeker’s Allowance if you are a lone parent or, in some circumstances, if you are ill/have disabilities. You cannot however claim Housing Benefit.
You are also not excluded from claiming Income Support, income-based Jobseeker's Allowance and Housing Benefit if you have lived for a continuous period of six months or more with:
your parent, or
someone who has parental responsibility for you, or
someone who has a residence order for you, if that order was in place immediately before a care order was made for you.
