E.ON has launched the cheapest tariff currently available as it bids to stop an exodus of customers to smaller suppliers.

It's the first time one of the so-called 'Big Six' energy suppliers has been top of the best buy tables this year.

The top tariff

E.ON's new 12-month fixed tariff will cost the average household £965, if they opt for paperless billing (you get a £10 discount if you skip postal bills). That works out £300 a year cheaper than the average energy deal.

What's more, you’ll earn £20 a year for having both your gas and electricity with E.ON, while you also earn Clubcard points.

And if you change your mind, the exit fee is far cheaper than its competitors at £5 per fuel, compared to £30 per fuel with other suppliers on the market.
