What you're paying, why, and the one or two things worth checking.
One bill has a supply charge, a delivery charge, a demand charge, riders, and taxes — all folded into one number nobody explains.
Certo separates them in the time it takes to read this sentence.

The questions every bill raises
Why is my bill this amount?
We separate usage, supply cost, and utility delivery charges so the total makes sense.
What rate am I actually paying?
Your effective rate per unit of usage, compared with what's typical for accounts like yours.
Who is my energy supplier?
Utilities and competitive suppliers can both appear on one bill — we tell you which is which.
Is this reading actual or estimated?
An estimated read can mean a correction is coming later. We flag it when we see one.
Why are delivery charges so high?
Delivery pays for the wires, not the electricity — and switching suppliers won't change it.
Can I do anything about it?
Sometimes the answer is "not much right now." We say that too, when it's true.
