I've been worrying about the £20 a week extra stopping for a while although I can't say I noticed an increase in the amount I was given. Today I've looked at the breakdown of the benefit and discovered that the extra was taken off me anyway due to the benefit cap. If I didn't get child maintenance, not that he pays the right amount, then I'd be scraping by at best. The benefit cap takes £380 a month off. During the top up times it was £460. So the actual amount I get hasn't changed. How can the government say they are helping when they aren't at all?
