I’ve just taken my first meter reading on the 3rd March, my bulb payment will be taken on the 8th, my app from previous supplier still shows usage. Who am I paying for these days
It is quite common to have an overlap on payments until the switch over is complete, it can take up to 6 weeks for final readings to be agreed . You will be credited back from your old supplier once they have agreed you final readings.
