Is this what my supplier will charge?

About these figures
These are Ofgem price-cap benchmarks for a default tariff paid by Direct Debit with a single-rate electricity meter, derived from Ofgem’s rounded annual cap levels. They are not a supplier quote. The cap limits rates, not your total bill: your actual cost depends on how much you use, how you pay and your tariff.
