About Zog Energy

Zog Energy is an independent gas-only supplier that was started in 2013. It was founded by Andrew Cleveland and Tony Chester in response to the bad customer service and high prices that they found in existing utility companies.

Since its opening, Zog Energy has consistently ranked among the country’s cheapest gas suppliers. Read on to learn more about Zog Energy’s prices and customer services.

Reviews: Is Zog Energy any good?

gas flame

The founders of Zog Energy have focused on keeping prices down by using cloud-computing services and lean management systems. Cheap prices sound fantastic, but there are a few things you should be aware of before you sign up.

The first thing is that Zog Energy doesn't have a contact telephone number for customers. While for some people this is no problem, people who prefer communicating by phone may be put off by this. This is further exacerbated by the fact that they don't have an online account, making some customers wonder - how on earth do I communicate with them when I have a problem?

Despite not having a contact telephone number for customer care, Zog has generally high ratings on customer review sites such as Trustpilot and Google reviews. The supplier is very proud of their customer service. Its practices are far from traditional and it’s shaking up the way customers interact with their energy supplier.

Zog Energy has an average rating of 4.7 out of five stars on Trustpilot. Out of 160 customer reviews, 90% scored the supplier as either good or excellent. The overwhelming amount of positive reviews generally allude to the supplier’s low prices, friendly staff and quick response time.

“I've been with Zog energy for more than 5 years and found them the cheapest and most honest and friendly company to deal with.”

AhmedTrustpilot review

Zog Energy, unlike many other smaller independent energy firms, has managed to maintain its high quality of customer service as it has grown. Maintaining their high levels of good service is a good sign as many energy companies start with fantastic reviews only to see a deterioration in customer service as they increase in size.

It’s also worth noting that Zog Energy has been certified as a Future 50 company. This award means that Zog has been voted as one of the most innovative and ambitious up and coming companies in Norfolk and Suffolk.

Zog Energy is also a certified ADR (alternative dispute resolution) provider. This means that should you have a dispute with the company, it will be easier to make a complaint and the process can be mediated by an outside body.

Zog Energy tariffs: Which is the cheapest?

Zog Energy offers five different gas tariffs. There are four fixed-rate tariffs of varying lengths and only one variable tariff.

Fixed tariffs are generally cheaper than variable ones. With a fixed-rate plan, you’re guaranteed that your gas rates will stay the same for the duration of the contract. This does not mean that the total charge on your bill will stay the same - that depends on how much gas you actually consume.

We break down Zog Energy’s tariffs below. Calculations are based on the national average consumption levels for a medium-sized home in London, which is 12,000 kWh of gas per year.

Zog Energy tariff prices
Tariff name Tariff type Estimated cost per month Estimated cost per year Exit fee
Zog Mercury 12 v38 Fixed for 1 year £30.89 £370.67 £30
Zog Mercury 24 v25 Fixed for 2 years £33.74 £404.85 £30
Zog Saturn 12 v18 Fixed for 1 year £40.93 £491.11 £0
Zog Saturn 24 v8 Fixed for 2 years £41.33 £496 £0
Zog Juniper Variable £44.08 £529 £0

As you can see in the table above, the Zog Mercury 12 v38 tariff offers the best deal for your gas. However, should you wish to leave one of the Mercury tariffs before your contract ends, you will need to pay an exit fee. This would be the best option for customers who have no intention of switching often.

How do prices compare to other suppliers?

Through a bit of research, we found that the Zog Mercury 12 v38 plan is not only Zog Energy’s cheapest tariff, but it’s also one of the cheapest tariffs on the UK energy market. The supplier often tops the list for offering the cheapest gas tariffs along with the following other energy companies:

So which of these companies is the cheapest gas supplier for your home? That depends on where you live and how much gas you consume. It’s always best to get a personalised quote when comparing energy prices if you’re looking for the cheapest option.

Zog Energy login: How do I access my account?

Are you having trouble accessing the Zog Energy customer login page? That’s because it doesn’t exist. As an energy company that only communicates with customers online, it’s odd that Zog Energy does not provide an online account management service.

Most online-only energy companies, such as Pure Planet Energy and Lumo Energy, offer a range of online services such as online accounts and apps.

Strangely, Zog Energy doesn't have any of these online services. To manage your energy account, we recommend you either send an email to Zog Energy or contact the supplier on Facebook Messenger.

If you just need to submit a meter reading, you can also do so on the Zog Energy website.

Is there a Zog Energy contact number?

Zog Energy does not have a contact number for customers. If you have a power cut, you should call 105. In the case of a gas leak, you should immediately call 0800 111 999.

For general customer queries or account questions, you should send an email to the gas supplier’s customer service department at hello@zogenergy.com.

You can also reach out to Zog Energy on social media via Facebook and Twitter, or write a letter addressed to Zog Energy Ltd, IP City Centre, 1 Bath Street, Ipswich, Suffolk, IP2 8SD.

The table below breaks down the different ways you can contact Zog Energy.

You will need to provide the following details for the Zog Energy meter reading:

Does Zog Energy use smart meters?

Zog Energy does not yet install smart meters for customers. The supplier plans to start rolling out smart meters later this year. Customers will be notified when smart meters are available in their area.

If you already have a smart meter and you decide to switch to Zog Energy, your meter will continue to work, but it will lose its smart functionality. It will operate as a traditional meter would, and you will need to submit your meter readings manually.
