HOME and families in Rotherham are being overcharged by the Big Six by more than £18 million a year, MP Sarah Champion warned.
The new figures, calculated by leading independent energy supplier First Utility , show that the majority of people in Rotherham are sitting on the most expensive energy tariffs on the marketplace, costing them up to an extra £327 every year.
This is despite Government rules, introduced in 2012, which mandated the Big Six should tell their customers if cheaper deals exist — a requirement some big suppliers are deliberately circumventing, Ms Champion said.
The MP urged households to switch energy supplier before winter begins.
She said: “With half-term just a few weeks away and Christmas coming up fast, every extra penny matters.
“Switching energy supplier only takes a few minutes, the Government guarantees you can switch in 21 days or less with no double-billing, and hard-working families could stand to save hundreds of pounds a year.”
