British Gas, EDF, EON and Octopus customers told to do 'important' thing on Monday

British Gas, EON, EDF and Octopus Energy customers have been urged to do one 'important' thing in six days. According to experts, those without a smart meter should hold off until Monday, July 1, to take readings.

The start of the month is when Ofgem introduces an energy price cap boost. According to the Express, it will be see an average of seven per cent, or £118.30, slashed off bills.

To avoid being incorrectly charged on the old, more expensive rate, people have been urged to take gas and electricity readings as soon as possible on Monday. This should be done after midnight, when the new rates come in.

Les Roberts, business energy comparison expert at Bionic, said: “On July 1, it’s important that those without a smart meter take a meter reading. This is when the energy price cap change comes into effect and this will result in your bills changing.

“Submitting meter readings is a good habit to get into, and submitting them monthly ensures that your bills are correct, regardless of which tariff you are on. Ultimately, the price you pay is determined by how much the energy supplier thinks you are using, so letting them know stops any random guesses and ensures you only pay for what you use.

“If you do spot mistakes from your meter readings to what is on your bills, you can then flag this with your supplier as well. If they don’t correct this based on the evidence you have, you can also refer your case to the Energy Ombudsman who will work with the supplier and yourself to resolve the complaint.”
