@lazyb Yes, it’s an industry standard -

thankyou from lazyb

The calorific value of gas (the amount of energy in a cubic meter) does alter depending on temperature, humidity and other factors. This factor is often overlooked when applying the conversion.

@Trebor1 If you mean that it’s often not appreciated that it’s a variable figure, then I take your point.
In their monthly statements Bulb do provide the figure they’ve used to calculate the bill. Using that figure, my spreadsheet always agrees with the amount charged.
