Millions of low-income households could see power bills cut after a watchdog's report into the UK's energy sector.
The Competition and Markets Authority (CMA) has proposed a price cap for all households using pre-payment meters.
It has also proposed that the regulator, Ofgem, keeps a database of customers that have been on a standard rate for three years.
This database will then be opened up so these customers can be targeted directly by other suppliers.
The proposals are designed to reform the energy market and increase competition to help consumers save money.
