If you don't provide opening meter readings when you switch, we receive deemed readings for your supply.
Deemed readings are calculated using your previous meter readings.
You may also have deemed meter readings if your meter was exchanged without recording your closing or opening readings.
Deemed readings can be disputed, for which there’s an industry-wide process that all suppliers follow. The best way to support any dispute is to provide regular meter readings. The more readings available, the more accurate the estimation.
