Nabuh Energy

Sheffield-based Nabuh Energy says it sells low-cost, hassle-free prepayment energy. It sells fixed deals for direct debit customers too, none of which have exit fees.

Nabuh Energy has been part of British Gas since 27 April 2021, after it bought the smaller brand. This means that British Gas supplies customers' gas and electricity (and you pay your bills to it). But the Nabuh Energy brand still exists, tariffs have stayed the same and you should contact Nabuh Energy with any queries.

National Gas

Previously known as British Natural Gas, this small supplier is not to be confused with Britain’s biggest supplier, British Gas. It sells only gas and says its priority is to save people money.

Neo Energy

Neo Energy was launched in early 2020 and is owned by Euston Energy.

It is the world’s first energy supplier to allow customers to pay with cryptocurrency. Customers can pay in pounds too and its tariffs have no exit fees.

It offered free electricity in June and July to customers who joined between 11 April and 30 April 2020. Some industry experts questioned the financial sustainability of the company for offering its customers free energy. Neo Energy’s CEO said ‘there are so many additional risks running an energy company and it’s just another one.’

Neon Reef

Poole-based newcomer Neon Reef stopped trading on 16 November 2021. If you're one of its 30,000 customers, you will be transferred to British Gas.

British Gas will contact you (by email, text and letter) shortly. While you're waiting, take a meter reading and submit it to Neon Reef. It's also a good idea to save a copy of your latest statement or take a screenshot of your account balance. 

Your account with British Gas won't be fully set-up for four to six weeks. Ofgem advises that you don't switch supplier before your new account is set up. This should make the process of transferring you to the new supplier and reimbursing your credit as smooth as possible.

Any credit you had with Neon Reef is safe. But it could take two to three months to get it back, British Gas says. Neon Reef's administrators have to finalise your account.

Neon Reef's customers managed their accounts via app, online and email. It didn't provide paper bills or have a phone line. It also donated to charity Shark Trust when customers sign up to its Reef One tariff.

A small proportion of the overall electricity Neon Reef sold was matched with renewable sources. It didn’t generate renewable electricity or buy it directly from renewable generators.

Neon Reef’s electricity fuel mix was 8.3% renewable, 8.2% nuclear and 78.3% from fossil fuels. 

For 2020/21 Neon Reef told us that 100% of the renewable electricity it sells would be matched with renewables by it buying REGO certificates.

Northumbria Energy

Northumbria Energy says it provides ‘first class customer service’ and guaranteed savings on your electricity bill.

Like Neo Energy, it is owned by Euston Energy. In March 2020, energy regulator Ofgem banned it from taking on new customers until it was able to use the wireless network for smart meters (called the DCC). The ban was lifted in May 2020 after it became a DCC user.

Northumbria Energy's fuel mix is 4% renewable, 9.8% nuclear and 81% fossil fuel (for 2019/20). It told us that 33% of its customers' electricity use will be matched with renewable sources, using renewable energy certificates for 2020/21.

It doesn’t generate renewable electricity or buy it directly from renewable generators.

Omni Energy

Yorkshire-based newcomer Omni Energy stopped trading on 2 November 2021. If you were among its 6,000 customers, your new supplier is Utilita.

Your new tariff will be Utilita's Smart Energy tariff which has no standing charge or exit fees. You can top-up as usual, using your Omni Energy top-up key or card. Utilita will send you new ones in the post.

Omni Energy said it 'makes prepayment and PAYG energy better'. It offered one tariff, which you manage via a smartphone app.

Yorkshire-based Omni Energy said it sold only renewable electricity. It did not generate renewable electricity or buy it directly from renewable generators. It matched its customers’ electricity use with renewables by buying renewable energy certificates.

Orbit Energy

Offshore wind turbines

Orbit Energy closed on 25 November 2021. If you're among its 65,000 customers, you are now a customer of Scottish Power. 

Your energy supply will continue as usual. Scottish Power says 'we'll work closely with Orbit Energy to make your transfer to us as smooth as possible'.

If you were in credit with Orbit Energy, Scottish Power will add it to your new account once Orbit Energy's administrators have notified it. This should be within three months but depends on the administrator, it says.

If you switched away from Orbit Energy, Scottish Power will send you a cheque for your credit.

If you have a traditional prepayment meter you can carry on topping-up as usual. Scottish Power will send you a new top-up device. When you get it, you should use it instead of your Orbit Energy one.

Find out what to do if your energy supplier closes.  

Orbit Energy promised 'stress-free' energy. Shell supplied its electricity and gas, which it said meant it could offer ‘secure, competitively priced’ energy.

Customers had to manage their account online.

Orbit Energy did not generate renewable electricity or buy it directly from renewable generators. It matched its customers’ electricity use with renewables by buying certificates.

Find out more about the differences between energy companies’ renewable electricity.

In March 2021 energy regulator Ofgem revealed that Orbit Energy is paying 723 of its customers an average of £9.79 each after overcharging them when they switched supplier or tariff between 2013 and 2020. It was one of 18 energy firms found by regulator Ofgem to have failed to uphold these rules. Over 1 million customers were affected overall.

PFP Energy

PFP Energy stopped trading on 7 September 2021. Its 82,000 customers were moved to British Gas, chosen by energy regulator Ofgem.

Ofgem says British Gas is offering a 'competitive' tariff. It will tell you your new rates when it gets in touch with you about the changes. 

You can then ask for British Gas' cheapest deal or switch supplier. Wait until your account is set up before switching so that there's no disruption to repaying any credit you had with PFP Energy.

If you were in credit to PFP Energy and switched before it closed, British Gas will also honour this.

PFP Energy launched in 2015 and was originally a not-for-profit supplier.

Social Energy had a unique set-up, helping customers install solar panels and a battery to store renewable electricity to power their homes. It paid customers for exported electricity and for helping balance the grid.

Social Energy Limited, is still operating. So if you have solar panels and a battery connected by the Social Energy Hub then it will still manage whether your renewable electricity is stored, imported or exported to the grid.
