Tariffs & Prices

The system of tariffs at Enstroga is simple and straight to the point. The company has three basic tariffs, two of which are duel-fuel (fixed and variable), and one that supplies electricity-only (fixed). Exit fees are applied on all fixed tariffs, meaning that you may have to pay for exiting your contract before the completion of its term.

At the moment Enstroga doesn’t have any tariffs for prepayment customers or those with Economy 7 meters. If you need help finding the best Pay As You Go or Economy 7 tariff, talk to a Selectra energy expert on 02039 360059.

Compare Enstroga to the rest of the market

  1. How do we compare Enstroga to the rest of the market?

    We use the energy price cap set by the industry regulator Ofgem as a benchmark by which to compare fixed energy tariffs. This cap sets the maximum amount that energy providers can charge their customers for the supply of gas and electricity per kWh and the maximum standing charge per day, combined in a single annualised figure.

  2. What is the energy price cap currently set at?

    The median energy price cap was reduced by over 5% in the latter half of 2019. It now sits at £1,179.00 for a duel-fuel supply. It's important to note that this is a median calculation; the price cap figure may differ depending on the region in which you live. To find out more about the energy price cap, head to our dedicated Ofgem price cap guide

  3. What would I pay with Enstroga?

    Based on a 2-3 bedroom home in London with the average UK household energy consumption rate, and taking into account standing charges, customers will pay £1,022.66 per year for the Evergreen Dual Plus tariff. For comparison, a 2-3 bedroom house in Manchester will pay £1,018.73, while the same household would pay £1,059.00 in Birmingham. All fall well below the price cap level

    It is difficult to assess the variable 'Energy' tariff in similar terms as the price of gas and electricity are subject to change. Standard variable tariffs are usually set at the price cap level.

  4. Can I get cheaper energy?

    Enstroga offers competitive pricing when compared to the market overall, which is what the majority of customers are looking for. However, its prices are certainly not the cheapest. To get the best deal for your home, why not talk to a Selectra energy expert? Call us on 02039 360059.

Fuel Mix

Enstroga is heavily reliant on natural gas, which, at 62.6%, makes up a sizeable amount of its energy supply. It also uses double the amount of coal (11.%8) than the national average, while renewables make up a pitiful 2.6% of its fuel mix.

Customers who are eco-conscious might want to try out some of the cheapest renewable energy providers or check out some of our Selectra favourites like Ecotricity or Bulb Energy. You might also want to check out our tips for saving electricity, which are great even if you aren’t with a renewable energy supplier!


With Enstroga, you only have the option of paying by direct debit. This means that you will be paying a fixed, monthly amount, commencing from the date you sign up. The amount you pay is based on your annual usage, which is calculated from the meter readings you provide.

If you have not provided your meter readings, Enstroga will estimate your bills from the last readings held or information retrieved from the national database.

Account login & app

Customers can access their My Enstroga online accounts through the login button below or through the provider's website: On the website's homepage, select the green My Enstroga button on the right of the menu bar. This will take you to the login portal where you will have to insert the username and password associated with your account.

Much like Enstroga's website, we have heard reports that it is extremely basic and riddled with problems - that is when it is working at all. Strangely enough, it appears that, unlike most companies, you can’t check your billing using Enstroga’s online portal.

Unfortunately, Enstroga doesn’t have a mobile energy app for iPhone or Android, which is surprising for an international company that has arms all over Europe.

Reviews: Is Enstroga any good?

Enstroga Energy has only been operating in the UK for a few years and while it has gained a lot of customers thanks to its low prices, it has already got a lot of customers’ backs up with its reputation for poor customer service.

Good to know: Who owns Enstroga?Enstroga UK is owned by the Europe-wide energy group known as the Enstroga group, with headquarters in Berlin, Germany. The UK arm of the group previously went under the name Comet Energy before rebranding in 2016.

Big in Europe, bad in the UK

This European giant is popular in its home country Germany, where on big review sites it performs strongly. However, this success doesn’t appear to have translated to its UK arm where, for example, on Trustpilot, only 8% of Enstroga customers feel that they are receiving good customer service.

In fact, we have struggled to find any raving Enstroga Energy reviews. Customers generally complain about the lack of contact from the company, missing welcome emails, waiting on the phone for hours trying to get through, being cut off by customer service, and no callbacks. Enstroga isn’t exactly shining at the moment, when it comes to doing right by its customers.

Problems with switching

The company has recently signed up to the Energy Switch Guarantee, a scheme designed to help customers feel more secure when switching energy providers. At the time of signing up, Jens Müller-Bennerscheidt, the Enstroga CEO, affirmed Enstroga's commitment to a simple and effective service.

However, customers have reported a host of problems with Enstroga’s switching process, including being blocked from switching from Enstroga to another provider.

Interestingly, a large number of Enstroga’s new customers appear to have switched over from Iresa Energy. Iresa was a beleaguered energy company that was shut down last month due to terrible customer service, and as far as we can see, customers may be in for more of the same with Enstroga.

Our take on Enstroga

Although the supplier has competitive prices, we would say that you might be better off going for an equally affordable supplier that is more established or offers better customer service, such as Boost Energy or Pure Planet Energy. Taken together with its fuel mix, Enstroga receives a Selectra score of two out of five stars.

If you are thinking about leaving Enstroga but you are not quite sure where you can get a the best deal for your household, get in touch with Selectra. We can give you expert advice and compare deals across the market.


Do you have a problem with Enstroga? You can contact its Customer Service team on 01158572572 (Monday to Friday: 8am-7pm) or writer a complaints email to to start the complaints procedure. When you submit your complaint, a customer service agent will try to resolve your problem over the phone by providing you with an apology and a resolution that is deemed appropriate.

If a customer service agent can’t resolve your problem then you can “escalate” your complaint to one of the supplier's dedicated customer service managers who will try to resolve your case as quickly as possible. Usually, they will aim to resolve your case in under 8 weeks.

If your complaint isn’t resolved in 8 weeks, you can ask for a “deadlock” letter and take your complaint to the energy ombudsman who will intervene on your behalf.

Enstroga energy meters

Enstroga has provided no information about smart meters. We assume that, for the moment at least, the company won’t be installing them.

If you are a customer who already has a smart meter you can still switch, but should note that you will most probably lose the 'smart' functionality of your meter. This means that you will have to return to doing meter readings manually.

Meter Reading

As with any supplier, customers should submit meter readings once a month, preferably about 5 days before the bill is due during the month.

With Enstroga you can submit your meter readings through the supplier's online portal, although many customers report not getting feedback from their meter readings or these meter readings being ignored, so we would recommend keeping an eye on your bills to make sure that the numbers are accurate.

Moving home

If you are moving home you can contact Enstroga by phone to give your final meter readings. This is something that you must remember to do before you move house in order to close your account and pay an accurate final bill or receive a credit refund owed to you. At the same time, if you wish to stay with the supplier, you can set up a supply to your new home before you move in.

Enstroga is part of the Energy Switch Guarantee, which means that setting up a supply with the provider should take no longer than 21 days, you’ll never have to pay for the same energy twice, and any overdue credits should be returned within 14 days of your final bill.

Warm Home Discount Scheme

Enstroga currently isn’t a part of the Warm Home Discount scheme as it doesn’t have more than 250,000 customers.

The Warm Home Discount scheme is a programme backed by the UK government of assist households in fuel poverty. Customers can get up to £140 discounted from their energy bills during the period of October to April.

If you are not eligible for the warm home discount but are in need of assistance with your bills, see out our dedicated energy schemes page to find out if you are eligible for other support programmes.
