Wirral households missed out on £21m savings last year because they didn’t change their energy supplier.

Figures from Ofgem show that savings of around £300 this year are achievable just by switching.

But a new Ipsos MORI survey from the Energy Saving Trust has found 71,226 homes across Wirral are on "Energy Autopilot."

Nearly 60% of non-switchers believe they’re on the cheapest energy tariff available, which is unlikely.

And that’s despite only 30% of all bill payers believing energy suppliers actively encourage customer loyalty.

The figures have been revealed ahead of "Big Energy Saving Week" - a UK-wide campaign between the Energy Saving Trust, Citizens Advice and the Department for Business, Energy and Industrial Strategy.

Running from next Monday, October 31, to Sunday, November 6, events will be held to offer advice on reducing energy costs and help people keep their homes warm ahead of winter.

An online price comparison tool from Citizens Advice can help bill payers find a cheaper supplier.

Completely impartial and including quotes from all energy suppliers, it offers a quick and easy way to see if you can unlock a better deal.

Philip Sellwood. chief executive of the EST, said: “Many bill payers in Wirral are missing out on substantial annual savings because they assume they are on the best tariff without actually checking.

"Prices fluctuate every year, so by not switching and being on ‘Energy Autopilot’, consumers may be sleepwalking towards having less money.”

Gillian Guy, chief executive of Citizens Advice, said: “Switching gas and electricity can help people cut their bills.

“Checking their current tariff and comparing prices regularly means people can spot the best new deals and switch to a supplier that gives them the best value for money.

“Citizens Advice will be hosting events in local communities throughout Big Energy Saving Week, where people can learn how to save energy, insulate their homes and compare prices to minimise their bills.”
