I see that Ofgem is still using the fictitious "average" home (the one that does not exist) for its price cap calculations. It says that the cap will reduce bills from £1,928 to £1,690 and the media plays along. It is nonsense.
Customers can spend what they like, be it more or less - there is no upper limit - no cap. It is the unit prices that matter. The new gas prices will be capped at 6p per kWh, and electricity at 24p per kWh. They compare to the current prices of 7.42p per kWh and 28.62p per kWh.
Last year my total energy bill came to £1,310.90p and that's some £600 less than the "cap". My forecast for this year is another £600, or more, below the cap.
However, they give with one hand and take with the other. Regular bill payers can now look forward to standing charges of 31p per day for gas and 60p for electricity - depending upon where you live, and don't forget the new £28 per year we all get to pay for the debts of those who will not pay.
