Working Tax Credit - 22 weeks grace period?

latinaid

I have seen the following info elsewhere - does anyone know if it's true?  I understand the theory of what's being said and it makes sense - just don't know about the 22 weeks bit?

If you have children and receive Child Tax Credits, do not apply for UC as they will stop.  Best thing to do if you receive Working Tax Credit is to log online and go to ‘change in work circumstances’ and change work hours to 40 and pay as £1. This will cause your award to be re-evaluated and you will get full WTC and CTC for up to 22 weeks.  This is a grace period HMRC give you to find work.  If you leave it at £1 after 22 weeks, any payments after the 22 weeks you will have to pay back.  This is information given to me by the Working Tax Credit office itself.
