Frequently Asked Questions

What does Calorific Value on my gas bill mean?

Calorific Value (CV) describes how much heat is generated when a known volume of gas is completely burned away.

This means that the CV measures the quality of gas supplied to a property.  Each bill we send you will show the CV that's been calculated for your area for that month (and will range between 37.5 - 43.0).
