Eon

A technical hitch at energy suppliers E.on Next and Sainsbury's Energy - which are both operated by E.on - means potentially thousands of customers will have their direct debit payments taken two weeks later than usual, and so users should put aside enough cash in their accounts to cover the bill when it is due.

Millions of EDF, Eon, Npower and Scottish Power customers will see energy bills hiked by £96/yr on average from 1 April. All four firms are raising prices by the maximum allowed under the new energy price cap announced earlier in February. But most households can beat the hikes and save £200/yr by switching to a cheaper deal. 

Furious E.on pay-as-you-go energy customers say they have been left without heating and power in the middle of winter after the firm admitted thousands have seen delays in online and app payments reaching meters. But you can top-up over the phone in the meantime. 

E.on has launched a new tariff which charges a fixed monthly bill, regardless of how much energy you actually use - but it's not cheap.

E.on is to increase average dual-fuel prices for around 1.8 million customers on its standard tariff by 4.8% in August - just months after it hit them with a backdoor price hike by scrapping a number of discounts.

Big six energy firm E.on has changed the smart meter letters it sends to customers - after MoneySavingExpert highlighted it was wrongly telling them it needed to install the meters in "all" homes.

From today all energy firms are banned from back-billing customers beyond 12 months if the delay is not their fault - here's what you need to know.

From today, up to two million customers on E.on's standard variable tariff will see their energy bills rise by an average of £22/year, as the company changes the way it charges.
