Zog energy is a company to avoid
Zog energy is a company to avoid. They make up estimated bills to increase direct debits. Shop around, there's better suppliers out there, these clowns are Mickey mouse on a good day!

Reply from Zog Energy
Helpful and efficient
Helpful and efficient. An excellent customer experience particularly compared to other utility providers I have used.
Cheap prices and good customer service
I can thoroughly recommend Zog, if you are comfortable communicating by email as they do not offer customer service over the phone. Having said that, they are extremely efficient and the one trivial query I have had with them was answered within minutes. They send out very easy to understand bills once a month and, if estimated, the estimation seems a reasonable figure. Though to be fair I do regularly give them meter readings - which is easier than with my electric company as you do not need to remember login details, just your customer number. I have been with them for years, joining very soon after they started up. At the end of each fixed rate term, I have done a comparison check, and Zog have usually been the cheapest, or if not then within £5 of the cheapest for the whole year. I have no connection to the company, just a very satisfied customer.
PS Just seen that I reviewed them in 2015 - forgotten all about that - still have the same opinion of them!
Excellent customer service
Zog supplied the flat I moved into and I stayed with them because of how helpful and professional their customer service team are, they went above and beyond to help me when I could find the meter for my flat and even sent me a meter key. Have never had any problem speaking to someone on the phone and get a quick response via email. Probably the best energy company I’ve used and would definitely recommend
Excellent value
An excellent no-frills company offering the lowest prices.
The billing is clear, and though their site doesn't have logins and account access to do things like view old bills, it's nevertheless sufficient.
I haven't found anyone else to come close to their prices.
Can't fault Zog for their service
Can't fault Zog for their service. Setting up an account and on-going support is really good. I've been with them a few years now and not had an issues unlike some other providers I could mention !
Puts other Gas suppliers to shame
Customer now for over 4 years - attracted first time by price , which still remains very very competative
Before you switch please remember two things 1) You send monthly meter readings
2) Contact is on line
I have always found customer service excellent - on the rare occasions I have had to contact them replies are quick, accurate and address the issue raised
My most recent contact has been in connection with reading my meter which is and always has been difficult to get to .
After a heart attack ( now recovered ) and bad knees ( old age) I contacted ZOG to see if they could arrange for someone to call to do 6 monthly readings.
Sorted with minimum of fuss - Thanks to all the fantastic staff
Billing system efficient and prompt - no big build up of debit/ credit balances ( if there is easy to obtain a refund and a lower DD)
Perhaps I have taken them for granted for all these years - but after the trouble I am having with my electricity supplier I have decided it is about time I recognised that I am so delighted I am with the " perfect" Gas supplier
Thanks !
I’ve been a zog energy customer for…
I’ve been a zog energy customer for many years now. I’ve always received very efficient service. No complaints at all. Prices are always competitive. I regularly send them up to date meter readings and in return you get regular account statements. Easy!! No surprises!!
Great service
Great service, good prices. Emails answered promptly. They don't mess about with your direct debit amounts through the year like many other companies. I requested to switch to a cheaper tariff mid contract and suggested my own monthly payment amount to clear the debit balance that had built up over the winter. Everything done efficiently, very happy with them.
Great customer services
Great customer services.
Moved house back in March, they issued my final bill within 1 day. wondered why they were still taking payments in May but realised they had kindly split my final bill in to installment due to high winter usage. Excellent honest company - Wish all companies operated like them.
Great customer service
My previous fixed tariff came to an end and Zog emailed a few weeks in advance to let me know and provide me with some options for new tariffs to join if I wanted to stay.
I selected a tariff, but then almost immediately changed my mind. I emailed Zog to explain and ask to be put another one of their tariffs. I also asked for my direct debit to be reduced to better reflect my usage and for the large amount of credit that I had built up to be refunded. I got a response within about half an hour by a very kind customer service rep who manually calculated my usage and immediately refunded the credit and reduced my direct debit.
I think there is supposed to be a system that adjusts your estimates and your direct debit automatically based on your usage, but it didn't get applied to me for some reason. Possibly because I was submitting readings in the middle of the month. However, the customer service was exemplary and so worthy of 5 stars in my opinion.
The website is pretty basic, but it works perfectly and I'm able to submit my readings each month without a problem.
I wish all utility companies were as…
I wish all utility companies were as good as Zog. They answer the phone promptly - no annoying press 1 etc. It’s often Tom that answers he’s extremely polite and helpful. Emails are usually answered within hours and it’s easy and straightforward.
I had spent 3 very frustrating hours with one of the big 6 being passed around as I was being pressured to have a smart meter. Wish I saved myself the stress and the bother. Zog calmed me down and dealt with my questions immediately. The prices are good but the customer service is beyond excellent.
Excellent gas supplier!
Excellent gas supplier! I have been with Zog for a number of years and I do not have any complaints. Very competitive tariffs. Invoices are acurate and easy to read. Meater readings are also easy to sumbit online. The only thing that I am missing is the online customer portal where I could see my whole account at a glance. Other than that I give them 5 BIG Stars!
Excellent customer service
I have been with Zog since 2017 and their service and prices are second to none. Renewal prices have always been lower than competitors. Responses to emails are prompt. If only all energy companies were like this...
Recently joined and impressed thus far
Recently joined and impressed thus far. Excellent prices. Excellent customer service - emailed them about an enquiry and got a concise reply 20mins later from Alex - insanely quick.
Excellent
I've been with Zog for gas for around five years now. Just renewed for another 2 years. They are straightforward and easy to deal with. I always communicate by email as I trust they will always reply. Sometimes within less that 30 mins I've had a reply. Meter readings are simple to submit on the website. Customer service has always been great. Prices are unbeatable, and I know I have saved a fortune over their competitors.
I became a Zog customers 4 or 5 years…
I became a Zog customers 4 or 5 years ago now. I have stayed with them even after shopping my gas plan every year or when my plan expired. At each renewal Zog has remained the best deal. Also dealing with meter readings, switching tariffs within Zog or dealing with customer services has been completely pain free and very easy. This is an example of a small provider that is making it all work!
Zog Energy
I have been with Zog Energy since April 2018. A two year fix to start with, then a 12 month fix and I have just fixed again for another 12 months. Very competively priced each time.
I was surprised when I first joined that there was no online account option, but the billing works well. I submit a meter reading on their website each month and get a bill a few days later by email. The bills are very clear and nicely laid out. I may lack excitement in my life, as I actually look forward to receiving them!
I have dealt with a lot of energy firms over recent years, for myself, my mother, my mother-in-law and as an executor for somebody else and some of the firms have been a nightmare (British Gas, how do you get bills wrong even with smart meters?). I have had no issues at all with Zog Energy and my direct debit hasn't had to change since the start.
As a Norwich City supporter, I have to gloss over the fact Zog are based in Ipswich. The thought that there is a well organised team in Ipswich is hard to accept.
Best customer service of ANY service company
I've been with Zog Energy for a couple of years and only switched because of their prices. Yesterday I needed to contact them to ask for a refund as my credit balance was way exceeding the gas cost for several months ahead. I was expecting the usual frustrating, "round the houses" marathon but I was wrong. My initial email request was answered by Alex within 5 minutes in which she asked for my current meter reading. This was sent to her and Alex responded 20 minutes later confirming the refund had been organised AND that she had reduced my Direct Debit payment to be more in line with my current usage. BEAT THAT all you other service companies !!
Once again - thank you Alex :-)
Great company with brilliant…
Great company with brilliant information and digital delivery. Customer service is excellent and have been with them for a few years. So much better and better value than old supplier British Gas. No hesitation in recommending and have done to friends.
