Meter reading

In the past I have accidentally submitted my gas for my electricity, I have entered today the correct one and I got a message stating this is much lower than previous, not sure what to do please advise.

Hey @jacquelineduggan, thanks for notifying us about the readings. If you are able to give us the correct readings for the dates of the initial switch date we can amend the system and notify your old supplier of the correct readings. Another method is using industry estimated readings for the first readings and billing you from them. A third method is if you could send us readings in a week by email we can then backdate using the reading to what it should have been on your start date. On our side, we will always ensure that us and your old supplier are using the same reading to bill you from and to so there is no overlap.
