People across Great Britain have been urged to take meter readings on Saturday as new energy prices come into force that are likely to save households hundreds of pounds a year.
The average price for each unit of electricity that someone uses has been slashed to 30p per unit, while gas prices will drop to 8p per unit.
It will save the average household around £426 a year on their energy bills, according to regulator Ofgem – which sets the levels and calculated average usage.
