What tariffs do E Energy offer?
E provides customers with a choice between both fixed-rate and variable-rate tariffs, all operating on a prepayment basis. Their primary fixed-rate tariff secures a customer’s energy price for twelve months. A key feature of this tariff is its flexibility, as E charges no exit fees if a customer chooses to switch to another provider before the contract term ends. To encourage customer retention, E offers a £50 loyalty bonus in the form of account credit to any customer who stays with them for a full twelve months, regardless of whether they are on a fixed or variable tariff.
Pricing is structured to incentivise smart meter adoption, with more competitive rates available to customers who have one installed. At present, E does not offer any tariffs specifically designed for electric vehicle owners. For customers who generate their own renewable energy, E provides one Smart Export Guarantee (SEG) tariff, which pays households for surplus electricity they export back to the National Grid. This is a variable-rate tariff that offers a modest rate for exported energy.

As a prepayment-only supplier, E Energy’s tariffs are designed to be competitive within this specific market. While prepayment tariffs are often more expensive than direct debit tariffs, E Energy aims to keep its prices as low as possible for its customers.

personally I’m happy that I moved to E. The staff are amazing and to have swipe cards for each meter is fantastic. You guys are great 👍
That company in my experience to-date, are a load of (not to use swear words i have in mind) rubbish at customer communication, i have tried for two weeks now to speak to E on the phone, kept hanging on for over 36 minutes, sent emails only receive fob-off emails, i am taking my case further
E won’t to charge me 30pound for new meter screen so I know what I useing a joke
Personally I have been with E for two years I spend literally 0 on gas for 6 months due to no standing charges and although it takes upto an hour to show up credit on the home hub I have never had a problem with it I know what I’m paying each month and feel great that I can rest assured my budget will cover it
As an E customer and been with them for several months now, and regret leaving my old supplier. I am spending more and more on electricity but actually using less. As a pensioner and live alone am careful as to how much I allocate for heating, I cut down usage, installed low energy bulbs etc. It was good for the first month then the home monitor shows am using high quantity of electricity when I am not. As a warning to people potentially want to move to E, Don’t shop around for a good supplier who isn’t out to cheat on you for profits. Avoid like the plague. I am a retired electrician.
HDU doesn’t work, prepayment credit isn’t going onto meter, have to call them every week to find out how much credit we have as meter isn’t working despite having 2 new ones fitted, customer service is poor. DONT GO WITH E!
App does not work most of the time , unreliable, also difficult to download app
