Why is it best for my smart meter to send readings every half hour?

When your meter sends readings every half hour, your display monitor shows you how much energy you're using every half hour (you can also see this information in a helpful chart by clicking on 'My energy graphs' in MyAccount).

With such an accurate picture, you can see where you might be able to save energy – and cut your energy bills.

Half-hourly reads also mean you avoid estimated bills (unless in the rare event your smart meter loses connection).

We only use the data we get from your smart meter to send you accurate bills, and to create the chart you see in MyAccount. We keep your information secure, and won't share it with anyone else unless you give us permission.
