German-owned Eon entered the UK energy market almost twenty years ago with the acquisition of Powergen - a familiar name to this day. It has established itself as one of the country’s major providers, with over four million customers, but is it worth switching to?

Eon Customer Service reviews

A look at Eon customer service reviews on the consumer review site Trustpilot paints a reasonably sunny picture of the service its customers are getting. Of over eleven thousand reviewers, well over half record having had a positive experience with Eon, with almost 60% giving the provider four stars or more. Its overall rating is 3.6 stars out of 5, which is a respectable one on a site that tends to draw those looking to complain.

Positive Eon customer service reviews tend to focus on the ease of switching or renewing and the efficiency of booking an engineer. Here is what one reviewer had to say about their visit from an engineer:

The installer phoned to confirm arrival, arrived on time, was super efficient, only took just under an hour, the power was off for a minimum period, he was clear and very polite. Altogether a totally painless experience!

These are promising signs, and important things to consider when you’re choosing your provider. Accidents or boiler issues can occur whoever you’re with and it’s reassuring to hear that customers generally have a good experience when calling out an engineer.

It’s important to acknowledge, however, that Eon customer service reviews are far from perfect. Well over half report good experiences, true, but more than a third of customers have a different story to tell. Of the 33% of reviewers who gave Eon just one or two-star scores, it’s hard to pin down just one or two complaints common to all.

A few reviewers have been making complaints about smart meters - either because they felt forced to have one installed against their will or because of problems resulting from their installation. Here is one example of an unhappy review:

Their tactics to get smart meters fitted border on disgraceful. Throughout the term of my tariff, I have received repeated calls, emails and letters to get one fitted 'as you agreed to as part of your current tariff'.

Other negative reviews cite poor service over the phone or problems with billing (whether related to smart meters or not). Generally, reviews on Trustpilot are positive, but around a third of customers report a negative experience. This is a significant minority, but it is shrinking, which is encouraging to see.

Eon tariffs

Eon tariffs can be either fixed or variable depending on which you sign up for. Exactly how much you pay will depend on where you live, how much you use and what your habits are, but we’re going to give you an idea of what to expect from Eon tariffs in this section.

Eon does offer some green energy tariffs, which are now widely available on the UK market, though the majority of their tariffs are far from it. Many providers at least offer deals which offset the carbon impact of the energy you use, and EON also offers this on some of its tariffs.

Eon offers special deals for those who drive electric hybrid vehicles. We’re going to take you through these deals first:

EON Charge

Here’s everything you need to know about the Eon Charge tariff broken down:

  • It comes with 100% renewable electricity* as standard.
  • It protects you from price increases for 24 months (subject to VAT and regulatory changes).
  • You’ll get a reward of 850 miles every year, equivalent to £30 (credited to your account six months into each year of your deal).
  • You must own or lease a plug-in electric or hybrid vehicle that’s registered with the DVLA.
  • An exit fee of £30 per fuel applies with this tariff.
  • It’s only available as a dual fuel tariff and you must pay by fixed monthly direct debit.
  • With a complex meter, you’ll be able to get this tariff only if you choose a single-rate quote.
  • By choosing this tariff you agree to a smart meter installation (where eligible).

*100% of your electricity matched with Renewable Energy Guarantees of Origin (REGOs) and 100% of your gas with Certified Emission Reduction Certificates (CERs).

We’re keen on any deal that incentivises opting for an electric or hybrid car, so we’re fans of the idea here. The fuel incentive for the vehicle is relatively small but it’s something, and the fact that 100% of the gas and electricity you use in your home is offset is positive.

More Eon tariffs

Eon offers several fixed energy tariffs, all with their own features you’ll want to take into consideration when choosing your deal. Here’s what they’re called:

  • Fix Online v44: an exclusive online tariff with fixed payments for 12 months, 25% off boiler cover, and a direct debit discount.
  • Fix 1 Year v6.
  • Fix 2 year V12: a 24-month fixed price deal with no exit fees for leaving.

These tariffs offer 100% renewable energy through carbon offsetting in the same way that the EON Charge tariff does. You can find out which ones do, as well as detailed pricing information (such as standing charges as unit rates) on the Eon website’s tariff section. You will also find information about Eon’s prepayment, pay as you go, and variable tariffs.

Eon’s fuel mix

Like all suppliers, Eon must disclose details of its fuel mix under law. The fuel mix you see below is an average of all the fuel used across its corporate and domestic ventures in the UK. As you can see from the table, the figures don’t make for great reading for the environmentally-conscious among us:


- Coal Natural gas Nuclear Renewables Other
UK average 3.9% 39.4% 16.6% 37.9% 2.2%
Eon UK average 3.7% 42.2% 4.8% 46.3% 3%

Despite claiming to offer 100% renewable deals by engaging in carbon offset programmes, Eon is slightly more reliant on fossil fuels than the national average. The table does show more investment on Eon’s part in a renewable future, however, with more energy sourced from renewable sources than the UK average.

Eon smart meter

Eon does offer its customers smart meters and is committed to rolling them out as per the government’s target to have one fitted in every UK home by 2020. It paused its rollout recently to make changes to the installation process but has now resumed the service so that customers can get their meter sent out with no-contact installation.

Want to know more about no-contact installation?Eon has put up a video on its website to explain how its engineers go about setting up your smart meter while keeping themselves and yourself safe.

Your Eon smart meter will come with free installation, which it says it does in order to make its customers more energy-efficient and to support a cleaner, greener Britain. Smarts meters help in this sense because they allow you to reduce waste (and overspending) by seeing exactly how much energy you’re using, what you’re using it on, and helping you to cut down where you can.

For more information on your Eon smart meter, see its website.
