How do you work out how much extra energy I'll use in the winter?

It is likely that you will use more energy in the colder months, so we suggest raising your direct debit by 10% to cover the cost of this.

When you joined OVO, we checked your details on a central database that includes a list of energy records for every address in the UK.

We were given your Estimated Annual Consumption (EAC) for your electricity and Annual Quantity (AQ) for your gas, based on all the readings from your property over the past 2 years. So it gives us an accurate picture of how much energy you usually use in a year. We then worked out how much energy you’d use over the year and set your Direct Debit payments.

As you’re likely to use more energy in the colder months, we add about 10% to your Direct Debit payments if you join us in the winter, to stop your account falling behind.
