Yes, they do do monthly whole bills by direct debit. You may get some at BT who say, "No you can only have monthly payment plan, if you want whole bill DD it needs to be quarterly".
But you can have whole bill monthly DD.
When I was with BT this is what I opted for, as did other family members and friends.
To the OP all phone providers you pay line rental in advance and call charges in arrears.
