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 customers 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

Neon Reef currently sells one fixed tariff with exit fees. Customers pay by direct debit.

Customers can manage their account via app, online account and email. It doesn't provide paper bills and doesn't have a phone line. 

Neon Reef is based in Poole and donates to charity Shark Trust when customers sign up to its Reef One tariff.

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

Neon Reef’s electricity fuel mix is 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 will 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.

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.
