@Lynnell Yes it is hard to find. Your bill is the answer. Page 2 shows which tariff you are on and your annual kwh usage. The Page 3 calculation shows the p/kwh and standing charges.
To check other tariffs you have to fill out a form on the Our Tariffs page on line.
I have spoken to three customer advisers on the telephone to ask what Kwh rate I am on.
Jamie said on 02-10-2019 it is16.4pKwh
Carol said on17-10-19 it is 20.095p Kwh
Lewis said on 25-10-19 it is 13.456Kwh.
I have tried to look for my Kwh rate on my internet link to my account but I can not find this basic information?
@garytaylor The easiest way to find out is to look at your online bill in your internet account. This give the p/kwh aand the daily standing charge.
note that the bill uses p/unit without vat which is added at the end of the calculation. Often SP quote a rate including the 5% vat.
