Energy price cap change mean lower bills but relief may be temporary

In addition, households have built up a collective debt to suppliers of about £3bn owing, primarily, to the pressure from high prices.

Those on prepayment meters, who tend to top up meters during the colder, darker months and are often under more financial pressure, will see a less immediate impact of a drop in prices in the summer.

The vast majority of households pay by direct debit, and their payments are smoothed out over the year. They should have been contacted by their supplier about the latest price changes.

Experts say it is a good idea to take a meter reading now, to ensure billpayers are charged at the correct rate.

Ofgem is reviewing the way the price cap is calculated, including sifting through a host of responses to a consultation on standing charges.
