Households across the UK are being urged to read their energy meter and take a photo of the reading before Thursday to avoid overpaying on their bills.

Energy bills are set to rise slightly from January 1 as Ofgem increases its price cap by 0.2%, meaning higher bills for households in England, Wales and Scotland on standard variable tariffs. The price hike means energy bills will go up by around 28p per month for the average household paying by direct debit for gas and electricity, amounting to a bill of £1,758 per year, up from the current £1,755. Ofgem’s price cap only sets the maximum rate per unit and standing charge that customers can be charged by suppliers when they’re not on a fixed tariff, but not the total bill. So ultimately, those who use more energy pay more.

To avoid the risk of overpaying for energy bills from January, households on standard variable tariffs who don’t have a smart meter are being urged to record and submit their meter readings before or on Thursday, January 1, so energy suppliers have an accurate and up-to-date reading.

Those on standard variable tariffs without a smart meter who fail to submit meter readings by January 1 risk having some of their usage estimated – and possibly charged the higher rates.

Price comparison website Uswitch says it’s also worth checking what fixed deals are currently available as households may be able to make savings against the January price cap, and by signing up to a fix, this gives you peace of mind that your rates won’t change for the duration of the deal.

Uswitch explains: “If you don’t have a smart meter, regularly take meter readings (especially the day before the new price cap level comes into effect) and submit them to your supplier.

“This makes sure your bill is accurate, and lets your supplier modify your direct debit to match your usage.”

MoneySavingExpert (MSE) also recommends taking a photo of your meter once you’ve taken a reading, that way you have evidence of the correct reading in case there are any issues with the amount you’re charged.

MSE said: “If you have smart meters that are working properly in smart mode, so they’re regularly sending meter readings to your provider, there’s no need to do anything, as they do it automatically.

“You may want to double-check your meters are sending reads, though. You can usually see this in your account or on your bill. You can also take a photo of your meters on the day, so you have the readings for safety.”
