Letters On An Energy Bill

[jesmond]

I know what some of the letters mean on energy bill eg s=smart e=estimate c=customer and I thought that mine as its the last bill as im switching suppliers would have had f=final on but it has d=deemed on it so has it the d=deemed on because ive given the new supplier the final readings and they have passed it onto old so that there is no interruption to supply

It's an estimate, in effect. Your new supplier will send your actual reading to your old supplier after the switch is completed, and you'll get a final bill. This can take up to six weeks.
