Energy customers across the UK are being urged to take immediate action as a critical deadline approaches. Major suppliers including British Gas, Octopus, EDF, EON, and Ovo have issued a stark warning: households must photograph their meters and submit up-to-date readings before Wednesday to ensure accurate billing under the new price cap effective from April 1.
Why This Urgent Call Matters
The new energy price cap, set to take effect on April 1, will alter the rates charged for gas and electricity. To prevent being overcharged for usage that occurred before the cap change, customers need to provide a clear record of their meter status as of March 31. This step is essential for drawing a definitive line between the old and new pricing structures.
Step-by-Step Guide to Meter Photography
For those with traditional meters—ones without digital screens or multiple buttons—the process requires careful attention to detail. First, ensure the meter reading itself is fully visible, with no obstructions or glare on the display. Second, capture the meter serial number, typically a combination of numbers and letters located near a barcode sticker.
Energy experts recommend taking two photos: a close-up shot of the reading and serial number, and a wider image showing about six inches around the meter to check for any issues with wires, cables, or pipes. If the supplier requests a timestamp, most smartphones automatically include this in the photo metadata, simplifying verification.
Expert Advice from Martin Lewis
Renowned financial commentator Martin Lewis has emphasized the importance of this action. In a recent statement, he advised, "Take a picture of your pre-payment meter on the 31st of March. If they try to back-charge you, you can prove exactly what you were using up until that date by emailing the photo to yourself for a timestamp."
He added, "This draws a line in the sand with the energy company. Every single unit of energy used until this meter reading should be charged at the cheaper rate. Don't rely on estimates that could result in higher charges."
Who Needs to Act and Exceptions
This directive applies primarily to customers without smart meters, as those devices automatically transmit readings. However, for the vast majority on traditional meters, submitting a reading and photographic evidence by Wednesday is crucial to avoid disputes and ensure fair billing under the new cap.
The affected companies include some of the UK's largest energy providers, such as OVO, EDF, EON, British Gas, and Octopus. Failure to comply could lead to inaccurate charges, making this a timely reminder for households to safeguard their finances.
