changing to Bulb from British gas

just in the last stage of changing by electric to Bulb.
My meter has two readings day and night rate. I dont think i told you this when applying to change supplier. Not sure you asked.
Is this a problem?

Hi! Thanks for getting in touch. That shouldn’t be a problem. We will get sent over the details of your meter from your old supplier, and this will let us know you have a day and night reading. By default you will be on our one rate tariff- so we won’t charge you peak/off-peak rates. If you want to be on the Economy 7 Tariff, we can put you on it, or want further details of this tariff. Just let us know
