Working tax credits and studying for a diploma

[Doubtfuldaphne]

Hello, I'm starting a diploma soon which is part time while dc's are at nursery/school.
Does anyone know how this might change my working tax credits? My Dh works but his income is low hence the top up from them
thanks

Does your husband work 30 hours per week?
Were you working before you decided to study your diploma.
I don't know how it works for couples as I've always applied as a single parent. Their website is pretty good. I think they base it on your income and total hours worked.
