Who are E Energy

E are a Birmingham-based energy supplier specialising in the pre-payment sector. They currently have 300,000 customers.

Normally an energy supplier’s pre-payment offering tends to be a ‘no frills’ offering, but the prepayment deal offered by E contains a number of extras, such as smart meter functionality and a loyalty bonus.

What tariffs do E Energy offer?

E offer both a fixed-rate tariff and a variable-rate tariff. The fixed-rate tariff is fixed for twelve months, although there are no exit fees if you switch to another provider before then. However, there is a £50 loyalty bonus for customers who stay with E for twelve months, either on the fixed-rate or the variable-rate tariff.

Prices are cheaper if you have a smart meter as different tariffs apply to smart meter users. However, there is no E tariff that has been designed specifically with electric vehicle users in mind.

E do not offer a renewable energy tariff although they offer one SEG tariff. The Smart Export Guarantee (SEG) replaced ‘feed-in’ tariffs and pays people who generate renewable energy if they do not use that energy and feed it back into the National Grid. E’s SEG tariff is the E SEG January2020v.1 tariff. This is a variable-rate tariff which currently pays a rate of 1p/kWh of electricity exported.

How do E Energy compare on price?

Customers who have responded to the Which? survey asking how they feel about E only rate E three stars out of five for value for money.

However, it is important to remember that pre-payment tariffs are generally more expensive that other tariffs, and E’s tariffs are not excessively priced compared to their pre-payment competitors.

What do other E Energy reviews say?

E scores four out of five stars on TrustPilot, with 57% of reviewers saying that the company is excellent. Most of those TrustPilot reviewers singled out E’s customer service as being their strong point.

However, 32% rated the company as bad, with most of those people complaining about billing problems and being charged too much for their energy.

E is placed joint 24th out of 35 energy suppliers in the Which? survey. Like the TrustPilot reviewers, respondents to the Which? survey scored E highly for customer service although they did not do as well in terms of perceived value for money or the performance of their digital services.

How green is E Energy’s energy?

E are open about their fuel mix, linking to a breakdown from every page on the E website. However, the company are not as environmentally friendly as some of their competitors.

At 325.4 g/kWh, E’s CO2 emissions are well above the industry average of 207.8 g/kWh. Only 8.9% of E’s electricity comes from renewable sources, with the majority (60.3%) coming from gas. Nuclear power accounts for 18.1% of E’s electricity supply, with coal accounting for a further 8.9%.

What is E Energy’s customer service like?

Online reviewers rate E’s customer service highly. According to energy regulator Ofgem data the company receive very few complaints, and those complaints they do receive are resolved quickly.

The company’s call centre is open for longer than most of their competitors’ call centres and according to Which? they answer phone calls in an impressive 68 seconds. However, there is no Live Chat facility on their website.

You can also contact E via email, either via their email address or via a contact form on their website, although they do not have a social media presence.

What is E Energy’s website/app like?

The E website is well designed, and everything is easy to find. It lets you manage your account and if you are on a smart meter, it will let you top up your account balance as well.

The E app, available for both Android and iOS devices, also lets you top up your account balance and manage your account. However, users have complained that it does not let you see your current account balance and crashes fairly often. It only scores three scores out of five on the Android Play Store, although the iOS version has been rated 4.7 stars out of five.

Because E only offer pre-payment tariffs, neither the website nor the app have a facility to let customers upload their meter readings.

Unusually for a company that has clearly given a lot of thought to its online presence, E does not have a presence on Facebook or Twitter.

What billing options are available?

E is a pre-payment only energy supplier, so you need to pay in advance for any energy that you use.

If you use a smart meter, top-ups can be made online or via the E app. If you don’t have a smart meter you need to top up your account at a PayPoint retailer.

Do E Energy offer smart meters?

E wants people to be on smart meters because that is one of their core selling points. Their service is built around the fact that you can top up your account online rather than having to go to a PayPoint retailer when your balance is running low.

E does not charge to install smart meters.

Do E Energy offer a recommend a friend referral scheme?

The E referral scheme gives the referrer and the new customer £25 when a new customer signs up. The new customer has to remain an E customer for 28 days before the credit is granted.

The credit comes in the form of credit towards your account rather than cash or vouchers. There is no limit to the number of referrals that an existing E customer can make.

Below are a few quick questions you may need answers to along with our E Energy review:

Do they offer a ‘Dual Fuel’ discount?

E do not offer an up-front ‘Dual Fuel’ discount. However, customers who use E for both gas and electricity get a £50 loyalty bonus if they stay with E for twelve months.

Will they offer to pay a customer’s exit fees when they join them?

E will not pay an exit fees if a customers previous energy supplier imposes such fees because the customer has switched to E before their previous energy contract has come to an end.

What happens if you move home whilst with them?

E does not give any advice to people moving home on their website. However, as E is a pre-payment provider there are no meter readings to give so when you move home you simply cancel your account at your previous home and start a new account at your new home.

Do they offer any incentives for joining?

You get a smart meter free of charge when you switch to E and if you have signed up via a referral code you also get £25 credit for joining.

Hi, I'm Rob and I run I initially started this project 5 years ago when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data backed reviews on all the suppliers available. Since then, I spent have a lot of time (too much some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible and any data is backed up by a source where necessary. I have also started writing guides on various energy related topics which hopefully you will find useful. If you find any issues, please use our contact form to let us know.

  1. 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

  2. E won’t to charge me 30pound for new meter screen so I know what I useing a joke

  3. 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

  4. 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.

  5. 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!

  6. App does not work most of the time , unreliable, also difficult to download app
