Energy consumers across the UK are being urged to take and submit their meter readings today, to avoid paying more after unit rates rise on January 1, 2023.
Emily Seymour, Which? energy editor, said: "A small number of customers face paying slightly higher energy rates in the New Year.
"If you've been notified of a price increase and have a tariff that requires meter readings, you might want to submit one before January 1 to ensure you're billed accurately."
