Yes. The Price Cap is set differently for those that pay by monthly direct debit, those that pay quarterly or on the receipt of a bill, and for those that prepay for their energy:
If you pay by direct debit, from 1 July to 30 September 2023 the Price Cap is an average £2,074 a year on typical use. From October, it'll be £1,923 a year.
If you pay by cash, cheque or quarterly direct debit, the Price Cap is £2,211 a year on typical use. From October, it'll be £2,052 a year. Ofgem says this is higher than paying by direct debit to reflect the additional costs from suppliers to bill those that don't pay by monthly direct debit.
If you prepay for your energy, the Price Cap is £2,077 a year on typical use. This has been discounted to £2,046 a year. Ofgem said it costs more to bill customers with prepayment meters, compared to those paying by direct debit, but the Government has provided a small discount on gas (0.261p/kWh) through the EPG, to bring the typical price to £2,046 a year. This is due to to its commitment to end the 'prepay premium'.
From October, it'll be £1,908 a year. The Government has again provided a small discount to the Price Cap rates, of 4.5p on the electricity standing charges and 5.9p on the gas standing charges.
