Frequently asked questions
Can I use this for gas?
It is a simple kWh-style calculator. Gas bills may need conversion from meter units to kWh, so use supplier bill figures where possible.
What is it best for?
It is best for checking whether usage and cost look broadly consistent with the readings and rates shown on the bill.
