The energy price cap is often talked about as a particular price, based on a ''typical'' user. The current energy price cap sets bills at £1,717 per year for a ''typical household'' until 31 October 2024.But what does that actually mean for you? The energy price cap is actually a cap on the unit rates you pay for each unit of energy you use, not the total amount.
