@Gingerkittykat that was for 3 kids:
CTC @ £65 per child per week
CB @ £48 per week
IS @ £70 per week (replaced with WTC & wages when working part time)
HB @ £550 per month
CTB @ £140 per month
This was 2010-2013 - Kids were also eligible for free school meals & school clothing grant - looking back it was a ridiculous amount of money & certainly a lot more than I needed to cover the basics. I also received around £350 per month in child maintenance which paid for holidays, activities & days out.
Adding that up gives an annual take home of around £28,000 given that my current take home (wages, benefits & maintenance) is £20,000 working full time it's a big drop. Essentially I've lost the equivalent of the HB & CTB but I now have to cover those costs from my income & although they've decreased as I've moved to a HA property rather than a private let it's a real time drop of around £5,000 in disposable income after housing costs.
Although the eldest isn't eligible for CB etc due to age she's still in education so is still financially reliant on me & in a couple of years DD2 will be the same & my income will drop further due to not receiving CB etc for her.
But if I didn't work at all I'd be screwed!
So while it's definitely worse for single parents just now & working full time may make them worse off in the short term I'd definitely recommend it as once the kids money stops you're on your own with UC which for me being unemployed living in my current property would be around £755 per month with £370 of that for my housing costs.
