When you join OVO, we check your details on a central database that includes a list of energy records for every address in the UK. This database provides your Estimated Annual Consumption (EAC) for your electricity and Annual Quantity (AQ) for your gas.
It’s based on all the readings from your home over the past two years, so it gives us an accurate picture of how much energy you’re likely to use in a year.
If it’s winter, we add on an extra 10% to your Direct Debit amount to cover the extra energy you’ll use in the cold weather. This is called the 'seasonal uplift', and helps you keep out of debt.
