Engie Energy UK: Reviews, Login, Prices & Contact

Engie logo

Engie is a relative newcomer in the market having started providing energy to UK homes in 2017. Behind this seemingly new player is a large multinational company with a long history in energy generation. It has recently focused its efforts on green energy, pulling out it’s investments in coal and stepping up the generation of renewable energy.


Having only provided gas and electricity to homes for a year, most of Engie’s reviews have been from people’s experience with switching. If you want long term reviews of their service you’ll have to wait a little longer to see how they fare in the long run.


Customers switching to Engie did so for two main reasons: the renewable energy and the price. People liked the fact that the energy mix (that’s how your electricity is generated) was high in renewables, in fact, it is roughly twice the national average on Engie’s standard tariff. Engie should definitely be on your shortlist if you’re looking for a renewable energy provider. Secondly is price, customers reported being offered lower prices than their existing supplier. Good if you can get it, as cheap prices and renewables don’t always go hand in hand.

Engie received positive reviews for it’s customer service. That’s good news if you ever need to call them. Following the experience of customers, it seems that you won’t be hanging on the line as customers who wrote both positive and negative reviews about Engie mentioned wait times being good. Once you’ve got through to them, you’ll find that the people on the other end are very pleasant to talk too. People mentioned their good phone manners and how informative the staff were. This should help keep your stress levels in check, as if there is one thing that will aggravate a problem, it’s having to wait on the line for a long time and then speak to someone who isn’t helpful.

While there was no problem when calling Engie, it seems there were a fair few problems with their service. This would explain why customers had to call them in the first place.

Many customers across the reviewing platforms such as Trustpilot, Facebook and Google reported bad billing as the main reason for their bad reviews. Some people said that Engie put them onto tariffs that were more expensive than the ones they had signed up for. So it transpired that after a few months of using the service, customers started to realise that more money was coming out of their account than they were expecting. They got in contact with Engie to find out what was happening and this is where reports start to get conflicting. In contrast to the positives we mentioned earlier, some users reported that they were unable to get a response from Engie either by calling them or emailing them. Others said that despite speaking with them, they were unable to resolve the matter and ended up switching again. There may be some truth to the findings, as Engie doesn’t respond to all reviews on Facebook, they only responded to the customers who complained politely or had positive things to say, not the ones who complained with less restraint. Which just goes to show, a little politeness goes a long way and can get you results.

Prices and Tariffs

Engie is committed to providing renewable energy and that is reflected in their range of tariffs. They recently updated their electricity tariffs so many of them now offer the option of upgrading to 100% renewable electricity on a standard tariff. Being green is certainly something you should consider when switching to another tariff but if you haven’t already, you should also bear in mind how the following factors can impact your decision to switch:

  • Economy 7 is good for users that consume a good proportion of their electricity off peak.
  • Economy 10 works on the same principle as economy 7 but with 10 hours of off peak electricity.
  • Fixed rate has advantages if you want to have the stability of fixed prices per unit of electricity and don’t plan on changing for a while.
  • Variable rate: If you want the flexibility of changing when you like and don’t mind the varying prices of gas and electricity.

So now you should have a good idea of which type of plan would be good for you. It's good to keep in mind that you will be charged exit or termination fees if you decide to leave your contract early. The small print on Engie contracts states that you will be liable to pay Engie “economic loss” for terminating the contract early. Good to know if you’re thinking of taking advantage of the attractive long term tariffs available but are thinking of terminating before the contract is over.

As a business you need to keep track of your overheads and also have something scalable and flexible to suit your business needs. Engie have tariffs that range from monthly pay as you go type tariffs up to 60 month fixed-term tariffs. Fixed term tariffs will tie you in with that provider for the duration of the contract, if you leave your contact with Engie early, exit or termination fees will be charged. Engie doesn't give an exact figure but if you read the small print you’re required to compensate Engie for the “economic loss”.

All business tariffs are upgradable so your business receives 100% renewable electricity and the good news is that there is no extra cost for upgrading and you can stay on your previous tariff. Great if you want to market your business as having green energy credentials or reduce the amount of carbon dioxide produced by your business. Reports have shown that small and large businesses are are increasingly using offsetting to comply with carbon reduction plans. By only using renewable energy in your business, your carbon footprint will be lower and therefore there will be less carbon dioxide to offset.

Business tariffs available to small and large businesses are shown in the table below.

A brief history

Engie has been providing gas and electricity to UK households since 2017, so it is a relative newcomer in the UK market. But delve a little deeper and you'll find that behind this apparently new company is a very long history. The company was founded in France in 1858 when it was known as the Universal Suez Canal Company, set up to construct the Suez Canal. It has since gone through a series of mergers and name changes, the most recent of which was when the French state gas supplier, Gaz de France merged with Suez in 2008 and subsequently changed its name to Engie in April 2015. Today, Engie is a large multinational utility company working in the creation and distribution of electricity. Recently it has invested heavily in renewable energy generation and cut all of its investments in coal plants.

Share price

Engie’s share price has remained relatively stable since the beginning of 2016, trading at around 13-16 USD a share from the previous all time high of 21.00 USD in June 2014. At that time, shares were traded under the name “Gaz de France” before changing its listing to Engie in 2015. See share price history below:
