Why are some parts of my energy graphs estimated?
If your smart meter doesn’t send us a reading for any reason, we’ll estimate the energy you used during that time. We’ll base this on the amount of energy you’ve used in the past.
You’ll see estimated consumption on the graph as grey, while the actual amounts you’ve used are red or blue. If we’ve had to estimate the energy you’re using for several days, it’s likely to be because we’ve been updating the software on your smart meter – it can’t send us readings while we’re doing that.
