My bill is showing as -£44.81

I went to pay my bill and it's showing as -£44.81

In the PDF for my bill it  states:
Plus balance brought forward from previous bills
Airtime charges -£89.62

Total credit due
We'll carry this credit forward to your next bill. -£44.81

Does this mean I don't have to pay this month?

If your bill shows a "-" then you are in credit, and your Direct Debit should show as £0 to be collected and the bill should show as paid.
