What Happened to Enstroga UK? FAQ

Enstroga UK Frequently Asked Questions

1) I'm an Enstroga customer - will I continue receiving energy?

Thanks to Ofgem's Supplier of Last Resort (SoLR) scheme, customers will continue to receive gas and electricity. Any energy supplier that goes bust has their licence revoked, and a bidding process is started to reassign their customers to another supplier, according to the scheme's terms. Ofgem announced in early October 2021 that E.ON Next would take on all 9,000 Enstroga UK customers.

When an energy provider closes, its website is often taken down soon after, so we recommend logging in to your customer portal as soon as possible and downloading any bills and statements so you have a written record of this information.

2) Will my energy bill change?

Former Enstroga UK customers will be put on a deemed tariff rate, which will be protected by the energy price cap. We recommend that you either shop around for a better deal or request that E.ON Next place you on a different tariff because these are some of the most expensive rates a supplier can charge. There are no exit fees levied against you under the SoLR scheme.

3) How can I contact my new supplier?

To get in touch with your new supplier, visit contact E.ON.

4) I’ve already starting switching suppliers. Will this still go through?

If you were already switching away from Enstroga, the process should still go ahead, and any Direct Debit you had set up with Enstroga UK should be automatically cancelled. We still advise you to double-check with your bank just to be sure.

5) My Enstroga account was in credit. Will my money be refunded?

All customer credit will be honoured under the terms of the Ofgem SoLR scheme.

6) I owed money to Enstroga. Will I still have to pay it back?

You will still be responsible for any outstanding debt owed on your energy contract. E.ON Next will let you know whether they will take on your debt or if you will have to work out a payment plan with an administrator, a company that takes over a failing business.

7) I don’t want to be with E.ON Next. Can I switch to a different supplier?

Once your account has been transferred from Enstroga to E.ON Next, you're free to switch to another supplier without incurring any exit fees or penalties. We work with a panel of top energy suppliers at Selectra, including British Gas and EDF. To learn more about our best deals, speak to an Energy Expert on 020 3936 0059 or a get a free callback now.

Tariffs & Prices

The system of tariffs at Enstroga was simple and straight to the point. The company had one fixed and one variable tariff, which were available as duel-fuel or electricity-only. Both tariffs were available on a standard meter or Economy 7.

Enstroga Evergreen Fix

Evergreen Fix is the provider's 12-month fixed-rate tariff, which is paid for through monthly direct debit.

Enstroga Evergreen Fix for Economy 7

The Evergreen Fix plan is also available for customers on Economy 7 meters. This type of tariff usually works best for electricity-only households that use overnight storage heaters.

Enstroga Price Cap Tariff

With the Enstroga Price Cap tariff, you are not tied into a contract and can leave any time you want without the need to pay exit fees. The downside to this type of tariff is that the unit rate and standing charge can change depending on market prices. See gas and electricity unit prices below. As with the Evergreen Fix, this Enstroga tariff also only has the option of paying by monthly direct debit.

Enstroga Price Cap Tariff for Economy 7

The Enstroga Price Cap tariff is also available for customers on Economy 7 meters.

Fuel Mix

Enstroga is heavily reliant on natural gas, which, at 72%, makes up a sizeable amount of its energy supply. It also uses almost more coal (6.3%) than the national average, while renewables make up just 8.3% of its fuel mix.

*Relates to electricity supplied in the period April 2019 to March 2020.
UK Average = Coal 3.9%, Natural Gas: 39.4%, Nuclear: 16.6%, Renewable: 37.9%, Other 2.2%.

With Enstroga, you only have the option of paying by monthly 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 type the username and password associated with your account.

Unfortunately, Enstroga doesn’t have a mobile energy app for iPhone or Android.

Reviews: Is Enstroga any good?

Enstroga Energy has only been operating in the UK for a few years and while it has gained a good number of customers thanks to its once low prices, its unit rates and standing charges have shot up in recent times.

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. Out of just over a thousand ratings on consumer reviews site Trustpilot, only 27% of Enstroga customers felt that they were receiving 'excellent' or 'great' customer service. Meanwhile, 70% awarded Enstroga a 'bad' or 'poor' rating.

In fact, we have struggled to find many raving Enstroga Energy reviews. Customers generally complain about the lack of contact from the company, missing welcome emails and waiting on the phone for hours trying to get through. Enstroga isn’t exactly shining at the moment, when it comes to doing right by its customers.

Problems with switching

The supplier is 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 UK'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.

Enstroga energy meters

Enstroga offers tariffs for standard credit meters, Economy 7 and smart meters.

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 some customers have reported 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 200,000 customers.

The Warm Home Discount scheme is a programme backed by the UK government to 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 our dedicated energy schemes page to find out if you are eligible for other support programmes.
