Hi, found this on directgov.co.uk. Hope it helps!
Changes expected to happen in 2012
From 21 May 2012, if your youngest child is aged five or over, or will become five that year, your Income Support may stop during that year.
What happens when your Income Support stops
Jobcentre Plus will contact you before your Income Support is due to stop to tell you when your last payment is due. Jobcentre Plus will also invite you to an interview with an adviser, who will explain what you need to do to make a claim for another benefit if you have not found paid work.
It is very important that you attend this interview so that you continue to receive the right benefits and financial support if you need it.
Making a claim to benefit as a lone parent
Most lone parents, with a youngest child of seven or over, making a new or repeat claim, are no longer entitled to Income Support only on the grounds of being a lone parent.
From 21 May 2012 this will be extended to most lone parents with a youngest child of five or over.
Other benefits which you may be entitled to
If you have not found work when your Income Support ends, or if you need to make a new claim as a lone parent, you will be able to apply for either Jobseeker's Allowance or Employment and Support Allowance.
Jobseeker's Allowance is the main benefit for people who are out of work. To receive it, you must be available for and actively looking for work. As a lone parent with a youngest child aged 12 or under, you have the right to restrict the hours you are available to work. This means that you will not be expected to work outside your child?s normal school hours. Your adviser will be able to provide you with more information.
