Zog Energy has gone bust due to the energy market crisis that has led to their financial instability. If you are their customer, you don’t need to worry! The energy watchdog Ofgem has appointed EDF to take on the customers of Zog Energy. In this article you will find out about the next steps and useful instructions to make sure that your transition to the new supplier goes smoothly.
Last update: June 2022

As as result of the UK energy crisis that is currently occurring, Zog Energy has unfortunately gone bust and is no longer operation. To help you navigate this crisis we prepared for you a guide on what to do if your energy supplier goes bust along with a page compiling all the information on the energy market crisis to ensure you stay updated on a daily basis.

What should Zog Energy customers do now?

On the 1st of December, Zog Energy announced that they have ceased trading. Their 11 700 customers have been transferred to EDF. If you are a customer of Zog Energy, you will find useful instructions below of what you can do and expect.

What happened to Zog Energy?

Like many other energy suppliers, Zog Energy has been struggling due to the energy market crisis in the UK, where the wholesale gas prices have been at their record high levels. This has made it impossible for the supplier to keep on offering its service to the customers.

Will my energy supply be interrupted?

You should not worry about your energy supply! Even though Zog Energy went bust, customers will not feel any interruptions of their supply. You will still have full access to gas and electricity in your household. Ofgem makes sure that the switch to the newly appointed supplier is as smooth as possible and customers will not have any issues with their supply.

Should I still be paying my bills to Zog Energy?

Although your new supplier has already been chosen, you may still need to pay back money to Zog Energy. It is best not to cancel your contract and make any changes to your payment agreement. EDF will contact you with the instructions to follow and will give you information about your new account, payment method, credit or debit.

If you have not been contacted yet, be patient! It might take some time until all 11 700 customers are contacted by EDF.

Should I take a meter reading?

It is recommended that you take a meter reading. This will be useful when setting up your new account with EDF.
It will also ensure that you are being charged correctly and you are not overpaying for your energy consumption. The meter reading serves as a proof of your actual energy consumption.

What happens if I am in debt or credit to Zog Energy?

If you are still in debt or in credit to Zog Energy, your situation depends on their agreement with EDF. The two suppliers will decide who will take care of these payments. When EDF contacts you about your new contract with them they will give you instructions about this matter. This process might take a few weeks, so just sit and wait for their call!

EDF to take over: will my bills go up?

Usually when a supplier goes bust, you will be put on a “deemed” contract by the new supplier, in this case EDF. This means that the contract is already selected for you and you don’t have the option to choose it yourself. Often, deemed contract can be higher than your old one.

What rate will I pay under my new EDF contract?

When your new supplier is chosen, you will start to pay the tariff of the deemed contract you have been put on with EDF. The rates should be communicated to you by EDF or their administrator.

We would recommend that you ask EDF to put you on their cheapest contract to minimise the costs and once the transfer is completed you can shop around and look for better tariffs or another energy supplier that meets your budget and needs.

Who chose EDF to be my new supplier?

The UK’s energy watchdog Ofgem (the Office of Gas and Electricity Markets) takes care of assigning customers of failed suppliers to more stable energy providers. They have chosen EDF to take on Zog Energy’s customers and the change came info force on the 4th of December. Ofgem chooses the new supplier based on their ability to take on all customers of the failed supplier and be able to provide energy at least for a temporary period.

When and how will I be contacted by EDF?

It is not clear now long in could take until the new supplier contacts you with instructions. Usually, the suppliers aim to make the transfer as fast as possible, but depending on the amount of customers that are being moved, it can take a little longer. The new supplier will have access to the contact details and address that you have provided, therefore you should make sure that your personal information is up to date!

Can I switch suppliers right now?

You should not switch your supplier before your transfer to EDF has been completed. Once you are officially moved to EDF, you can shop around and look for a new supplier of your choice.

Do I have to remain on contract with EDF?

No, you do not need to stay on contract with EDF. However, you cannot directly switch to a new supplier after Zog Energy has gone bust. Wait until you are moved to EDF and then start the process of switching to the supplier of your choice. Furthermore, it is best to wait for EDF to contact you and sort out the remaining credits or debts you might have.

However, if you were in the process of switching from Zog Energy to another supplier before it went bust, your credit balance will remain intact and the switch should go as planned.

EDF tariffs in 2021

Although you will be put under a deemed tariff with EDF, you can still consider some of their other tariffs and switch to one of them that better meets your needs and budget. In the following section you can find out the variable, fixed and economy 7 tariffs of EDF.

EDF Variable Rate Tariffs

EDF has one standard variable tariff for variable rates. The advantage for having a variable rate is the flexibility in switching plans. This comes at a cost though, which is the chance of higher rates if the market price is higher.

What was Zog Energy?

Starting with gas and with intentions to move to electricity in the future, Zog currently only supplied energy because it’s the highest proportion of domestic customers’ fuel bills. Zog believed that the majority of the UK are still on old tariffs which may not be cost-efficient or fair, and they aimed to make this easy with a simple switching process and by offering ‘the most competitive prices available’. Zog Energy was in the ‘Future 50’, an accolade given to recognise the most innovative and fast-growing companies in Norfolk and Suffolk.

Who owned Zog Energy?

In 2012, Zog was founded by Andrew Cleveland and Anthony (Tony) Chester. Since its conception, the two award-winning entrepreneurs had kept control of their business, and were the two owners as well as active company directors of the independent gas supplier.

How many customers did Zog Energy have?

The latest publicly available data from them suggests that they supplied gas to fewer than 20,000 UK domestic customers at present.

Was Zog Energy any good?

One of the main things that people said about Zog was how consistently low priced they were.

All energy suppliers have good points and bad points, below are some of Zog Energy’s.

Their plus points…

  • Consistently low prices, very competitive pricing
  • Customers were pleased with their customer service
  • A choice of fixed and variable tariffs, even though they only supplied gas.

Their downfalls…

  • They didn’t have a phone number, which was be irritating for customers
  • Only accessible by email or Facebook messenger
  • Customers were unable to manage their accounts online
  • They didn’t provide or support smart meters, nor did they support prepayment meters
  • Gas only, so no opportunity for renewable energy sources
  • Not suitable for dual fuel(electricity and gas) customers.

Zog Energy customer reviews

While they were still a small energy supplier (relatively speaking), their customer feedback was quite limited, and they were not included in wider energy surveys by independent parties such as Which?.

However, we can look at their Trustpilot page to find some of their reviews! They have been collecting customer reviews since March 2018, and in that time they’ve received almost 200 customer reviews.

Of those received, 88% are ‘Excellent’, 3% ‘Great’, 2% ‘Average’, 2% ‘Poor’ and 5% ‘Bad’, meaning that 91% of their ratings are rated as Excellent or Great.

Their positive reviews were along the lines of…

  • Excellent/Great customer service by staff members
  • Competitive rates and pricing
  • Meter readings easy to submit and communications are easy.

While their (very few) negative reviews mentioned…

  • Issues with final bills
  • Some customers had issue with variable tariffs, with prices increasing along the term of their agreement
  • Long timescales for refunds for credit balances in some cases.

What tariffs did Zog Energy have?

As mentioned above, Zog Energy was committed to supply energy to their customers at a low cost with clear and straightforward tariffs. Zog Energy offered a total of five different gas tariff plans to their customers, one variable rate tariff and four unique fixed rate energy tariffs.

Zog Energy Variable Rate Tariffs

As the only variable rate tariff that Zog Energy offered this also happened to be their default tariff, which means this was the tariff plan that customers were switched to automatically if they let their contract tariff deals lapse before resigning a new contract.

The variable rate means that the costs in this tariff are not stable, they will rise or fall in accordance to the cost of energy within the UK, should energy costs increase so will the costs of this tariff.

Cost of this tariff can be seen here:


Plan Tariff type Type of fuel Standing charge (p/day) Unit rate cost (p/kWh) Average total annual cost (£/year) Exit cost (£/fuel)
Zog Jupiter Variable Rate Gas 25.200 p* 4.010 p* £ 653.443** £ 0.000

** Based on the Typical Domestic Consumption Values (TDCV) defined by Ofgem. On average: 2,900.00 kWh of electricity and 12,000.00 kWh of gas per year.

Zog Energy Fixed Rate Tariffs

Zog offered 4 different fixed rate tariff plans, two of which were fixed for a 12 month period and the other two for 24 months. What that means is during that period of time your rates are fixed, so they will not go up or down even if the cost of energy in the UK happens to rise or fall during the contracted period of time.

The costs on these tariffs can be seen here:


Plan Tariff type Type of fuel Standing charge (p/day) Unit rate cost (p/kWh) Average total annual cost (£/year) Exit cost (£/fuel)
Zog Mercury 12 12 Month Fixed Rate Gas 26.250 p* 8.562 p* £ 1294.558** £ 30.000

Was Zog Energy cheap?

While we never like to throw around the word ‘cheap’, Zog Energy was known for their low domestic gas pricing. Their whole focus was on supplying affordable energy to households, and they did this by using cost-effective methods for energy supply, customer service and developing a business with cheaper overheads than the big six and the competition.

Zog Energy fuel mix

As a gas-only energy supplier, they did not have a fuel mix that we can report on!

What other products & services did Zog provide?

As of August 2021, Zog Energy only provided domestic gas supply to UK customers. Although, in September 2017, they received their electricity supply certificate from Ofgem, we did not see any electricity supply and dual fuel tariffs from Zog before they went bust.

Did Zog Energy have smart meters?

No, they did not provide smart meters. Although they planned a rollout in 2020, it did not happen.

How to contact Zog Energy

If you’re one of their failed customers, unfortunately they don’t have a publicised phone number at present. However, you can get in touch with them through their email addresses which are outlined below.

Zog Energy phone number

Although some customers have mentioned calling on their Trustpilot reviews, there is no publicised phone number for Zog Energy, and they encourage their customers and prospective customers to contact them online, and manage their switch online.

Zog, however, do supply key phone numbers for emergencies which include calling 0880 111 999 in a gas emergency. For example, if customers know there is a leak or they can smell gas in their home.

FAQ

Why did Zog Energy go bust?

Due to the rising wholesale gas prices and the energy market crisis in the UK more than 25 energy suppliers have gone bust. Zog Energy was another one to follow, after it became financially impossible for them to keep on running their business. That is why, the company decided to cease trading in the beginning of December 2021.

What should I do after Zog Energy going bust?

If you are a customer of Zog Energy, you don't need to do anything at this moment. You will still have access to energy in your household. EDF will contact you soon with instructions about your transfer and any other matter about your account. While you wait, it is best to take a meter reading for future reference!

Why is EDF my new supplier?

EDF was appointed by the energy regulator Ofgem, after considering if the supplier is able to take on the customers of Zog Energy. If you do not want to be a customer of EDF, you can switch to another supplier of your choice, but only after your transfer to EDF is completed.
