Who is Nabuh Energy?

Nabuh Energy Limited is a gas and electricity supplier based in Sheffield. It focuses on tariffs for prepayment meters, aiming to offer some of the cheapest pay-as-you-go tariffs on the market, and also offers a number of fixed-rate tariffs paid by direct debit.

Nabuh Energy has already signed up 7,000 customers since opening its doors for business in July 2018. By the end of 2018, they are hoping to have 80,000. The company has a small office with 10 employees in Sheffield and 50 salespeople in a call centre in the city, but despite their size, they are aiming high with their level of customer service.

We are definitely giving the Big Six a run for their money. I just don’t think people realise there is an alternative. People need to understand that going with a small energy provider is not that big a risk - and they usually save you money.

Nabuh Energy CEO

Who owns Nabuh Energy?

The CEO of Nabuh Energy, Klaus Bach, is a shareholder in Juhl Bach Holding, which is one of the biggest family-owned private companies in Denmark. It was £2 million of funding from this company which helped set up Nabuh energy.


Nabuh Energy reviews online do not paint a particularly good picture of the company. For example, 83% of all reviews on Trustpilot rate Nabuh Energy as ‘bad’, leaving it with an overall rating of just 1.4 out of 5. Most complaints focus on poor customer service and problems with topping up, which is a major concern for a prepayment focused energy provider.

Online top up doesn't work even after confirming details numerous times over the phone, trying to top up over the phone on automatic payment the same, getting in touch with customer service is a nightmare, it feels like they have a team of 1, if you want to listen to music for hours call Nabuh customer service. Wish to god I had never switched.

Poor Nabuh Energy reviews continue on Google, with a rating of 1.6 out of 5. Again, customers mention huge issues with topping up their prepayment meters, such as the app taking 20 minutes to complete a top up, as well as inadequate customer service.

The picture doesn’t get any better in Citizen’s Advice September to December ratings. Nabuh Energy comes in 39th out of 40 suppliers with a poor overall review of just 1.9 out of 5. With a high amount of complaints (62.1 per 100,000 customers), a long average call wait time (8:21) and only 93.7% of customers receiving bills on time, we can see why Nabuh has such a low rating.

The call wait time is particularlyfrustrating as Nabuh Energy has said it aims to answer the phone in less than 30 seconds! When we called it took 5 minutes to get through to a customer service agent. The company says it has made Facebook chat available so that more customers can get through, but we waited 1 hour until we got a response. Not great if you have an urgent problem!

Overall, reviews of Nabuh Energy suggest the company is failing in some major areas, including customer service and providing adequate top up services. It may have some low prices, but these can’t make up for some of these burning problems.

The Nabuh Energy app is designed for prepayment customers so they can top up their meters from their phones, making it quicker and easier than ever before.

The app can be downloaded from the Google Play Store for Android and the App Store for Apple devices. Unfortunately, it does not have great reviews with a score of 1.5/5 on the App Store and 1.3/5 on Google Play. The main complaint is that the app is very slow, meaning it actually takes a long time to top up.

To get the app up and running, follow these simple steps:

  1. Register your account using the details given during sign up.
  2. Once you're logged in, you will need to add your payment card. Click on the symbol in the top right to edit your profile, then select 'Visa' in the top right.
  3. Select 'Add New Card', fill in your payment details and click the 'Save' button, and then select 'Done' in the top right corner.
  4. Go back to the 'Top Up' page and select the fuel type - either 'Gas' or 'Electricity'. Then select the amount you would like to top up by.
  5. Choose how you would like to receive confirmation, either through SMS or Email.
  6. Click 'Select a Card' and choose the card you have saved with your account. Finally, click 'Top Up'. Shortly after, you will receive a receipt through your preferred method of confirmation.

Meter Reading

Nabuh Energy provides a good variety of ways to submit your meter readings. You can not only submit your meter readings through the online portal but also by telephone, on their website or by email if you prefer.

If for any reason you can’t submit your meter readings the company will estimate them. However, Nabuh Energy wants to keep your readings as accurate as possible to avoid large unwanted bills coming through the post.

Top up - where can I top up Nabuh Energy?

There are a number of different ways you can top up your credit with Nabuh Energy. If you have a smart prepayment meter, you can top up online, via the app or over the phone. If you have a traditional meter, you need to top up at your local PayPoint store. Let’s go through each option one by one.

Friendly and emergency credit

gas meter

Nabuh Energy emergency credit will kick in once you have used all the credit you have paid for, to give you a chance to top up before your electricity and/or gas cuts off. The amount of emergency credit you use will be taken off your next top up. Emergency credit is not unlimited and will eventually run out. In this case, your meter will disconnect until you top up - you will need to top up by at least enough credit to cover all the emergency credit you used plus £1.

To ensure your supply is not cut off during evenings, weekends and bank holidays, Nabuh Energy also offers friendly credit. Friendly credit is applicable Monday to Thursday from 7:30pm to 12pm, from Friday 7:30pm till Monday at 12pm, and all UK bank holidays. It will kick in if you use up all the credit you paid for during these hours. You will have to pay it back when you next top up.

Tariffs and prices

Nabuh Energy currently offers four tariffs: a prepayment tariff and three direct debit fixed-rate tariffs.

The direct debit tariffs are as followed:

  • The Jack tariff - fixed-rate for 12 months for traditional meters, no exit fees
  • The Zara tariff - fixed-rate for 12 months for traditional meters, no exit fees (only available online)
  • The Mel tariff - fixed-rate for 12 months for smart meters, no exit fees

Prepayment tariff

Nabuh Energy has one prepayment tariff, currently called the Lizzy tariff. Although it is a prepayment meter, unit rates are fixed for the first 12 months and there are no exit fees. There are three versions available. One for traditional meters, one for Economy 7 meters, and one for smart meters.


As with all providers, Nabuh Energy prices will vary depending on where you live and how much energy you use. To give you some idea of its prices, we have calculated the annual cost of its prepayment tariff and one of the direct debit tariffs for a household in London that consumes a medium amount of energy.

Nabuh is a paperless energy supplier and sends all their correspondence by email. Every month you will receive an email to let you know that your Nabuh Energy statement is ready. Paper copies can be sent on request and Nabuh also caters for those with visual disabilities by providing information in Braille.

If the bill is estimated you can provide meter readings to make them more accurate unless you have a smart meter when these will be done automatically for you. Currently, Nabuh Energy has a refer a friend deal where customers can get £25 credit on their meter for either their gas or electricity if they refer a friend to Nabuh Energy.

Business Energy

Nabuh Energy doesn’t offer business tariffs as it is focusing on the domestic market. If you are interested in a business tariff, call our energy experts on 02039 360059 to compare your options and find the best energy deal for your business.

Fuel mix

Fuel mix refers to the sources a company gets its energy from, e.g. natural gas and renewables. More and more companies are trying to increase their use of green energy by getting more of their electricity from sustainable sources.

Unfortunately, Nabuh Energy ltd is not performing well in the renewable energy stakes. Despite claiming it is working towards the goal of only using green energy, it currently gets less electricity from sustainable sources than the national average.

From March 2018 to April 2019, Nabuh Energy got most of its energy from natural gas and only 2.6% from renewables!

Smart Meters

Nabuh Energy is installing smart meters and can support second-generation smart meters (SMETS2 ) installed by other providers. It offers prepayment smart meters as well as smart meters for people who pay by direct debit. With both smart meters, you do not need to submit meter readings as it is done automatically.

Current customers interested in getting a Nabuh Energy smart meter can register their interest and will be contacted when the company is installing in their given area.

Warm Home Discount

Nabuh Energy doesn’t currently offer the Warm Home Discount to their customers, although they have ambitions to do so in the future.

Despite this, you might find that a Nabuh Energy tariff without the discount is still cheaper than a tariff offered by one of the Big Six with the discount. Give Selectra a call on 02039 360059 to compare and find the cheapest option for you!
