From the day you apply your payment will be 5 weeks from that date. Then after that monthly. I would say you will get help with childcare if you get any UC entitlement but definitely worth doing a benefit calculator to work out roughly what you will get. As above you can get an advancement on your payment but they will recover this over your future payments. Hope this helps. This is the more accurate benefit calculator https://betteroffcalculator.co.uk/login
@Emily thank you do you know how long it takes to hear back about whether you have been accepted to get help? X
I believe it is when the first payment comes in (I've not claimed myself). The policy in practice is pretty accurate id you fill it out correctly x
If you claim UC you can get a loan from them to help with things before you get your entitlement. Doesn't usually take too long providing you give evidence of everything they need and proof your identity etc xx
