I received my first gas and electricity bill last week, which was based on estimates since I had only provided a reading when I moved in. However, after realising I needed to submit monthly readings, I submitted the readings straight away and realised I was overcharged. In that month, I spent less energy than what was actually estimated.
Will the amount I was charged for be adjust now that the real usage can be calculated? How will I be refunded for that?
Many thanks for your help!

The info below has been taken from this topic on estimated annual consumption (EAC), projected usage and estimates. It will explain why an EAC is used to estimate usage in the absence of actual readings.
If your readings are being estimated badly, it might be due to a lack of readings, and an out of date or wrong EAC. Reach out to our Support team to get this EAC figure checked, sort a refund, submit a reading, and consider getting a smart meter fitted! You can do a lot of that on your online account before calling as well
What is an EAC?
EAC stands for Estimated Annual Consumption. We (and the rest of the industry) are able to use this figure to forecast the energy usage at a property over the next 12 months.
How do we use an EAC?
- Sometimes to Calculate your Direct Debit (see ‘Usage projection’ for more info)
- Estimating readings when we have no 'actual' readings
- Estimating consumption when a meter is faulty
We don't always use EAC to predict a member's usage - as stated below, EAC is only used for supplies where you don’t have a smart meter and there's no actual readings in the past 12 months.
How do we update an EAC?
Whenever a new reading is submitted to industry, a new EAC is calculated and sent to us to use.
If your EAC is incorrect, you should keep sending us regular readings. As the EAC is calculated based on the entire reading history of an electricity supply (MPAN), submitting regular readings over a period of time will gradually change the EAC until it matches the member's usage. The better alternative is to get a smart meter!
