Enstroga Energy Review Summary



  • Not very environmentally friendly
  • Poor customer service
  • Very basic online functionality

Who are Enstroga Energy

Estronga are a new entrant to the UK energy supply market, but are part of a large, Europe-wide energy supply group with a presence in Austia, Germany, Portugal and Spain.

They claim that their aim is to supply cheaper, greener energy, with a particular focus on customer service.

What tariffs do Enstroga Energy offer?

Enstroga offer two 12-month, fixed rate tariffs. One is based on electricity supply only and the other is for customers who use Enstroga for both electricity and gas. There is a £36.75 exit fee per fuel.

There is also a variable rate tariff. This tariff does not have an exit fee.

There are no tariffs aimed at electric vehicle owners and a pre-payment tariff is not offered. Enstroga do not offer a ‘feed-in’ tariff either.

How do Enstroga Energy compare on price?

Enstroga offer cheaper energy via their ‘Dual Fuel’ tariff but overall their prices are not particularly competitive. Many customers have complained that having been lured in with cheap prices up front, the actual price increased considerably once they switched.

What do other Enstroga Energy reviews say?

Despite claiming that their aim is superior customer service, online reviews of Enstroga paint a different story.

Enstroga only scores 1.5 out of five stars on TrustPilot. Most of the reviewers (89%) rated the company as poor or bad. A large number of the reviews mention that the reviewer had to contact the ombudsman.

As a relative new entrant to the UK energy supply market, Which? and Citizen’s Advice do not have enough data to draw any conclusions about Enstroga.

How green is Enstroga’s energy?

Enstroga are transparent about their fuel mix, but although they claim that they supply green energy, only 2.6% of their electricity comes from renewable sources. This is considerably lower than the 29% UK average.

The main source of Enstroga’s electricity is gas (62.6%) with nuclear (19%) and coal (11.8%) also featuring prominently.

What is Enstroga Energy’s customer service like?

Enstroga can be contact by email or phone only. There is no live chat option at their website.

Response time data is not available because Enstroga are a relatively new entrant to the UK market, but many of the reviewers online have been critical of Enstroga saying that it is impossible to get hold of them on the phone and that they take several days to answer emails.

What is Enstroga Energy’s website/app like?

Enstroga’s website contains very little information and has a cheap feel to it.

Online functionality is also limited. A number of online reviewers have stated that the they have found the company’s My Enstroga facility is often online, and even when it is online, My Enstroga doesn’t allow customers to check their billing. Some customers have reported that meter readings submitted via My Enstroga have been ignored.

Unusually for an energy supplier that is part of a large, Europe-wide energy supply group, Enstroga does not have an app.

What billing options are available?

Enstroga accept payment via monthly direct debit only. Payment is taken one month in advance, although for people with a poor credit rating Enstroga can sometimes require payment of three months in advance.

The monthly direct debit is based on your estimated energy use, although if you supply meter readings the monthly direct debit is based on your actual energy use.

Enstroga does not offer a pre-payment billing option.

Do Enstroga Energy offer smart meters?

No, and there are no plans to do so. If you have a smart meter you will lose all smart functionality when you switch and will have to submit meter readings manually.

Do Enstroga Energy offer a recommend a friend referral scheme?

No. There are no incentives for referring friends and family to Enstroga.

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

Enstroga do not offer pre-payment meters and customers who are existing pre-payment customers cannot switch to Enstroga.

Do they accept Economy 7?

Are they signed up to the Warm Home Discount?

Enstroga is not signed up to the Warm Home Discount.

Are they signed up to the Energy Switch Guarantee?

Enstroga are signed up to the Energy Switch Guarantee but many of the online reviewers have reported having problems switching their energy supply to Enstroga. There are also many people who have reported that they have found it difficult to move away from Enstroga.

Do they mention about the Priority Services Register?

Yes. You have to phone up to register though, as you cannot register online.

Do they offer a ‘Dual Fuel’ discount?

Enstroga offer a cheaper tariff to customers who use them for both electricity and gas supply than they do if a customer uses them for electricity supply only.

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

Enstroga will not pay any exit fees that are charged by a customer’s previous energy supplier. Those fees remain the responsibility of the customer.

What happens if you move home whilst with them?

If you move home while you are an Enstroga customer you need to either email or phone the company to let them know your final meter reading and your new address.

Do they offer any incentives for joining?

There are no specific incentives to join Enstroga.

Rob runs Energy-Review.co.uk. The project initially began when he switched energy suppliers for the first time and found there wasn't a website that provided simple, data backed reviews on all the suppliers available. Since then, Rob has spent considerable time looking at all publicly available data about each supplier and writing reviews using this information. Reviews are updated as regularly as possible and any data is backed up by a source where necessary. If you find any issues, please use our contact form to let us know.
