@tori1301 If your baby turns 9 months old in September, they would normally start funded hours from the term after they turn 9 months, which in your case is the January term.
The guidance about applying by 31 August for parents returning to work between 1 May and 30 September applies when the child is already old enough to take the hours that term (usually over 1 year old), so unfortunately, in your situation, even though you’re returning to work in September and have a childcare code, the baby is too young to use the hours until the January term.
I know that’s tough, especially as a single parent needing full-time care. The advice from HMRC and your local provider would be the same: you can’t start the funded hours early just because you’re returning to work — eligibility is based on the baby’s age and the term rules.
You might want to take a look at your eligibility for Tax-Free Childcare, which has the same income criteria as 30 hours, but you don't need to wait for the termly deadline to start using it. You can find out more about Tax-Free Childcare on www.childcarechoices.gov.uk.
