FAQs
Is this my official gas bill?
No. It is a planning estimate based on the usage and rates you enter. Your supplier’s official bill may include extra tariffs, discounts or regional charges.
How are cubic metres converted to kWh?
They are multiplied by 11.14, the commonly used conversion factor. Your supplier may apply a slightly different calorific value, so treat the result as an estimate.
Where do I find my rates?
Your rate per kWh and standing charge are printed on your gas bill or listed in your supplier’s tariff documents.
Is my data sent anywhere?
No. The estimate is calculated entirely in your browser and never transmits or saves your entries.
