Childcare Grant amount

I am planning on applying for a full time PGCE to start next year, I have 2 children and currently claim the childcare element of universal credit. I just wondered if anyone could give me an idea of how much childcare grant we might be eligible for? My husband currently earns £25878 before tax, and I would have no income apart from a student loan if I gave up my current job to do the course. Thank you

Thank you, but it only gives the upper limit for childcare grant and from other threads on here I understand we’ll get a much smaller amount however I can’t find that information anywhere.
