You can get up to £500 every 3 months (up to £2,000 a year) for each of your children to help with the costs of childcare. 

This goes up to £1,000 every 3 months if a child is disabled (up to £4,000 a year). 
If you get Tax-Free Childcare, you’ll set up an online childcare account for your child. 
For every £8 you pay into this account, the government will pay in £2 to use to pay your provider. 
You can get Tax-Free Childcare at the same time as 30 hours free childcare if you’re eligible for both.
