Top five cheapest energy deals in September 2016

Switch away from standard energy tariffs to save

Man looking at his energy bill and laptop

Are you on a standard tariff with one of the biggest energy suppliers – and paying too much?

Switching energy supplier is on the up so far this year, with a million more people than in 2015 changing their gas or electricity supplier. If you aren’t among them, find out how much you could save this month if you’re on a standard energy tariff with one of the big suppliers.

Despite higher levels of switching, two thirds of energy customers in the UK are still on expensive standard tariffs, energy regulator Ofgem also revealed. Our research shows you could save up to £307 by switching from one of these tariffs to the cheapest deal on the market this month.

The cheapest energy deals are usually fixed deals which guarantee you a price for your gas or electricity for a certain period (often a year) and may charge you a fee if you want to end the deal early. But the two cheapest deals this month don’t charge an exit fee – so you can switch again if you spot a better deal.
