No nonsense Gas
Have been with Zog energy for a few years now and I’m normally a serial switcher,I have never had to contact anyone at Zog because I’ve not had any reason to,I submit readings every 4-6 weeks and that’s it,no fuss.Get an email once a month with my account status and that’s it. Highly recommend Zog to supply you with very competitive price on the gas they supply and look forward to buying electricity if the price is right.
No hassle gas and a breath of fresh air!
Zog - What a fantastic company to do business with.
I just wanted to report what excellent customer service Zog Energy have provided for two years now, and how refreshing this is to find in a marketplace which seems to be filled with poor customer experiences. This is on top of their very reasonable energy prices.
I know all about poor customer experiences. My previous supplier collapsed, and the Supplier-of-last-Resort picked up the supply, placing me on a costly default tariff. I looked at what their best fixed tariff was. It was rubbish, as was their customer service. It took an Ombudsman Services case, many hours and phone calls and emails, and 18 months to retrieve a small refund and overturn a debt claim and threat of court action by this supplier-of-last-resort.
After shopping around I chose to try Zog, based on reasonable gas rates, good trading history and positive online reviews. "We shall see", I said.
Well - the excellent customer service demonstration came when my battery operated digital gas meter failed, twice! The first time, they happily adjusted the assumed (unmetered) gas consumption after a very straightforward discussion of my actual meter readings prior to the fault to generate a better estimate.
Both times, they were able to quickly organise a technician to fit a replacement meter.
My initial two year fixed tariff comes to an end shortly, and after another online scan of the market, Zog came second in the list by a tiny margin. The other supplier had absolutely shocking customer reviews on trustpilot. I had no hesitation in renewing with Zog.
Lazy Customer Service
Disappointed. When I registered online for Zog gas to be my supplier I received an email from a customer service agent who asked for the MPRN to start the process. I found this strange cause energy companies find out this info when switching a household from a different supplier. I told him that I don’t have MPRN cause i just bought the house and have not received any letter from the current energy company. The agent then responded that I should call the energy provider and if I don’t have the energy providers details I should go online and find out. This really shocked me as it came across as though he did not want to do his job. I asked for him to involve his supervisor and explain why he insists on me getting the MPRN. The agent then emailed that it’s the company policy for apartments or split properties to provide MPRN. I responded that I have a detached house therefore this should not be an issue. This was a complete waste of time and shows laziness. It takes 10 seconds to google an address to find out the property type. And it’s takes another 10 seconds to find out the gas provider online. Please train your agents how to handle customers as this was so unprofessional.

A hidden gem!
We switched to Zog two years ago and have just renewed for another two.
Their pricing is the best, and Customer Service is perfect - swift action when needed, do what they say - and no unnecessary emails from them.
Zog is a hidden gem!
Customer service done right.
Why can't all energy suppliers be like Zog? After years of struggling to get basic customer service from numerous 'big six' suppliers I transferred to Zog. My gas has been supplied at a more competitive rate than any 'value' dual fuel deal; I have received helpful & timely customer service, no call centre call queues, emails responded promptly & phone appointment call backs. In an industry that is blighted by erroneous billing, inexplicable DD hikes & Ofgem fines they have renewed my faith in an industry that badly needs customer service. Highly recommended & I have renewed with them for the 7th year & saved money in the process. 5 star company
Fair prices but no account dashboard to access your account details online & they use estimated readings even though you submit actual readings
They offer fair prices. My two gripes are that they do not remind you to submit a meter reading each month/quarter like other companies and they do not have an account dashboard interface, so you can not view your usage, compare it to the previous year, change your direct debit payments/dates etc. You have to email them to do this. I told them at the beginning of my first year that they need to provide this in order to offer transparency and the customer an easy way to do things for themselves regarding their account. I was told that this would be passed on, but it's still the same a year later-still no account dashboard interface available.
UPDATE APRIL 2021-They have gone down in my estimation as I've just realised they've not been updating my statements with my ACTUAL readings, they've continued to base it on estimated readings. Very unacceptable and the likely reason they do not have the online dashboard for you to view a full year in one go, as this would be easier to spot things like this. Read a review that pointed out the same as me about online access in 2018, Zog's response was "we recognise this is something customers want & are working hard on it behind the scenes". Fast forward 3 years to 2021, still no online interface or app. Tells you all you need to know. Be careful of this trick of using estimated readings if you join them, scrutinise your statements.
REPLY TO ZOG REPLY-3 years on & you say you are in the "testing phase" of implementing an online dashboard! I don't believe you, 3 years from now you will still be saying the same! Re asking for 2 readings a year is shocking & shows you are happy for customers bills to be based on estimated readings which could cause them to massively overpay or underpay. I submitted my actual reading in time for the March bill, it wasn't used & still wasn't present on my April bill, it had been discarded & estimated readings have been used instead-unacceptable

ZOG Energy = Excellent
I have been with Zog Energy since 2014 and I can honstlet say I have never looked back! They are excellent! Brilliant customer service, cheap gas (well as cheap as it can be), and no hassle whatsoever! What more could you want. :)
Zog energy are superb
Zog energy are superb. I have been with them since march "2014". How many other power companies keep customers that long. They always keep an eye on your payments and adjust up or down accordingly but only after consulting with you first. If you have reason to contact them they always reply in a short space of time. Great tariff, great customer service and unless their prices go through the roof, zog energy will keep me as a customer forever...Thanks Zog Energy.
Easy peasy highly recommended
Website easy to navigate, statements very clear, responsive to changing direct debits when in credit or arrears and simple to submit meter readings. Best of all still cheapest tariff on comparison sites so might buck the trend in valuing customer loyalty.....let's hope so but I plan to check to keep them on their toes

I’ve received excellent service and staff that are absolutely second to none. The questions I ask are answered instantly. Thank you Zog!

We switched to Zog 6 years ago and couldn’t be happier with their product, pricing and excellent customer service, which is second to none. If you haven’t checked them out, please do. They saved us a fortune in gas bills over the past 6 years. I wouldn’t go anywhere else.
Zog are fantastic
Zog are fantastic. I am a cold-hearted switcher. I switch to the cheapest every year. I have been with Zog three years. They don't mess about with your direct debit amounts. Entering a meter reading is very simple, they provide all the forgettable (acc number etc.) info on an email reminder and a link to the webpage for meter readings. The renewal process is very clear. You click one link in an email, then are sent to a table of rates, with your yearly consumption and the prediction should you renew, with the option of tariffs presented. Stark contrast to Utility Point (electric) who are currently trying to trick me into renewing onto a rate that is not their cheapest.
Consistently the cheapest supplier with simple, clear and accurate billing
I have been with ZOG for 5 years now and have just signed up for another year. In that time I have had absolutely no billing problems whatsoever. They are consistently the cheapest supplier with simple, clear and accurate billing. They make sound estimations if monthly meter readings are missed and collect accurate monthly direct debits averaged over the year. My only negative is that they only supply gas, I have never found the cheapest electricity supplier to be as consistent and straightforward to deal with and I have to change my electricity supplier annually.
Excellent customer service
I have been with Zog for a number of years now never had any complaints, I thought I would just check my account balance and found out that I was over £200 in credit, I emailed Zog regarding this and within 15 minutes I had a reply to say that my direct debit has been amended and that I would be getting a refund for the excess credit, excellent service can't fault them.

Zog are the best there prices low they respond to to your queries quickly your bill is always spot on its never too far overestimated or under estimated for the month they just make it a dream to deal with them
Very pleased with their services

It is always a pleasure dealing with Zog energy, everything is always dealt with so efficiently and the customer service is always 100%. Zog energy is by far one of the best suppliers I have dealt with, today Tom helped me out - thanks for your great customer service 👍
Great service
Just had my annual statement full of useful info - another example of the great service offered by Zog. They continue to be very reliable, very competitive on price, always provide comprehensible and clear communication in their correspondance. I trust them.
Handles zero gas usage well
Switching gas was very smooth, and they handle the fact we don't actually use gas at the moment well, trusting us that meter readings don't change, unlike EDF which kept rejecting the readings
Just started third year with Zog
Just started third year with Zog. Never had any problems. Whenever (3 times) that I ever had a question or wanted to make an extra payment, Customer Service response has been prompt and helpful. I submit monthly readings and monitor the account. Billing is easy to understand. Best bit is that even though I'm gas only, Martin Lewis's "Energy Club" cannot beat my deals past (2yr fixed) and current (1yr). To be fair I came to Zog as a best deal on the Energy Club site. They were not a recommended option since being a newcomer back then, there was little feedback. I "gambled" and I can only relate my positive experience and value with Zog.
