Anybody with British Gas as their energy provider has been given a week's warning to act now or face higher bills in the future.
At the beginning of July, the Ofgem price cap that limits how much people can pay for their energy per unit price was lowered from £2,500 to £2,074 per year.
And now that the Government's Energy Price Guarantee has come to an end, people are being urged to submit a meter reading before July 14 - otherwise British Gas will estimate their usage and customers could end up paying more than they need to.
