Will money be reduced automatically?

[#1]

My uncle signed up for Plusnet and I referred him, he is now live. Do I have to do anything to get the small reduction? or is it automatic.
This is what it says

On the top it says your current referrals credit £0.00

you dont get the money til the month after the first bill is paid, I take it your input is what is shown on your referal list
