About three million households across the UK already benefit from an energy price cap.
Homes with pre-pay energy meters will see bills for the next year going down by an average of £19.
This latest price cap for pre-pay meters came into force on 1 October, and built on the original price cap introduced in April.
Who will benefit from a cap?
Along with people on pre-pay energy meters, one million vulnerable consumers on the Warm Home Discount will benefit from an energy price cap from February 2018.
According to energy regulator Ofgem, this will see an extra £120 knocked off annual fuel bills. This is on top of the £140 discount for winter energy payments people on the Warm Home Discount already receive.
