When we calculate your bill, we try to use your actual consumption for each day from your smart meter, in order to get a correctly weighted average price for the billing period.
If this isn't possible (for example, if we are missing some consumption data), we will use your total consumption over the billing period, and allocate it to days based on industry coefficients that reflect actual weather.
We are unlikely to be able to recalculate your bill, even if we later receive your actual consumption data, as re-billing is just as likely to increase charges for a customer as reduce them, and time-consuming, when our priority is on minimising the cost of this tariff, and makes bills harder to comprehend and follow for customers.
