Unfortunately nobody can predict with any certainty how much energy bills will rise (if they rise at all) because the wholesale energy market is so unpredictable at the moment. With most of the country on a standard variable tariff because the fixed deals they were on have run out and almost no good-value fixes are being offered by suppliers, the level of the energy price cap becomes important here. It has actually decreased twice in a row and is predicted to decrease again from October 2023.
