There are currently more than 50 firms you can buy your gas and electricity from in England, Scotland and Wales. 

That’s many times the number that existed in the 1990s when the market was privatised, creating the six biggest suppliers: British Gas, EDF Energy, Eon, Npower, Scottish Power and SSE.

Although these six suppliers still dominate the market (along with Ovo Energy which bought SSE’s customers) there are lots of small energy companies trying to set themselves apart. So use this to your advantage and seek out an energy supplier that suits you.

While these firms are too small to have a rating in our latest energy supplier survey, we've previously seen small firms among the best of the bunch when we've rated them for the first time. So you might pick the small firm that's a future Which? Recommended Provider. That said, we've also found small firms falling short in our survey or going bust.

To help you get started, here's an introduction to every small energy supplier in Great Britain. Click on a company’s name above to skip to its profile.

Affect Energy

Affect Energy says it’s ‘working hard to make buying energy better’. Owned by Octopus Energy, it’s based in Shoreham-by-Sea on the south coast. 

It claims that its team’s experience with the biggest energy suppliers and focus on customer service set it apart.


Set up in 2017, Ampower says it uses affordable green energy to help customers cut their carbon footprint and save money. It does not currently sell 100% renewable electricity, but plans to do so. 

Its customers can choose whether or not to buy renewable electricity. Tariffs don't have exit fees.

Ampower was the second-fastest energy supplier to answer the phone in our latest customer waiting times snapshot investigation, taking just 1m04s on average to pick-up.

British Gas Evolve

Launched in 2020, British Gas Evolve is a new brand from the big supplier. It promises competitively-priced energy, including offsetting your electricity use with energy from 100% renewable sources.

Customers must manage their account entirely online as there is no customer service phone support.

Co-operative Energy

Co-operative Energy says it provides good value, simplicity and transparency to customers. All its tariffs have 100% renewable electricity.

Customers' gas and electricity is supplied by Octopus Energy, after Co-op Energy joined the brand in September 2019. Octopus Energy also provides its customer service. Co-operative Energy is still responsible for attracting new customers though. 

The two brands are working together to increase community-generated power in the UK. One of Co-operative Energy's tariffs is powered by 100% community-generated electricity - the only UK tariff to do this, according to the firm. The tariff also comes with carbon offsetting for gas use.

Co-operative Energy customers can become members of The Midcounties Co-operative (the UK's largest independent co-operative) and have a say in how it's run.

Previously it has had a ranking in the annual Which? energy survey results. We were unable to gather feedback from enough customers this year to give it a score.

London-based Daligas only supplies gas to households, and sells only one tariff. It's a variable tariff with no exit fees and customers have to pay by direct debit.

It claims to have cheaper prices, achieved by low operating costs, an innovative approach to buying energy and good systems.


Ebico is a not-for-profit supplier which partners with Octopus Energy to supply its customers' gas and electricity. 

Ebico is responsible for acquiring new customers while Octopus also provides its customer service. 

It sells tariffs for both credit and prepayment meter customers with no exit fees. It also sells smart radiator valves.

In September 2020, Ebico's customers were moved to British Gas when the big firm bought Robin Hood Energy's customers. At that time, Robin Hood Energy supplied Ebico's customers with gas and electricity.


Part of a European-wide energy group, Enstroga has recently joined the UK market. It says its mission is to 'bring its expertise and know-how to consumers looking for a better alternative to the big suppliers'.

Entice Energy

Entice Energy is an energy supplier based in Mansfield. If offers fixed variable tariffs, all of which require direct debit payments, and come with online-only bills and account management. 

It applies a ‘winter weighting’ if you join between September and March – this means that you pay more in the winter months than in the summer to reflect your energy use.

It says it offers ‘energy-free customer service’. You can book an appointment to speak with an adviser, use its live chat or phone it.

Eon Next

Eon Next is the 'newest, next face' of big brand Eon. Customers of Npower Select, Powershop Wasps Energy and Wigan Warriors Energy are now supplied by Eon Next after Npower became part of the Eon Group. 

It sells 100% renewable electricity, doesn't charge exit fees and says that customers are looked after by dedicated UK-based 'energy specialists'.

ESB Energy

ESB stands for Electricity Supply Board, which is the state energy provider in Ireland. It now supplies nearly 100,000 homes in England, Scotland and Wales too, after already being involved in the power generation sector in Britain.

ESB Energy says it provides 'customer care that actually cares'. All of its tariffs have 100% renewable electricity and it offers a tariff specifically for electric vehicle drivers.

In March 2021, Ofgem announced that ESB Energy was paying out nearly £50,000 to 1,961 customers after overcharging them when they switched supplier or tariff between 2013 and 2020. It was one of 18 energy firms found to have failed to uphold these rules. Over 1 million customers were affected. ESB Energy’s affected customers will receive £25.39 each, on average.

It combines gas and electricity, phone lines, broadband and TV services in one bill, which can be split so housemates pay their share independently. Set up in 2006, it works in partnership with SSE, which is now part of Ovo Energy.

Good Energy

Good Energy was the first dedicated 100% renewable electricity supplier, founded over 20 years ago. It sources its electricity from wind, biogeneration, solar and hydropower, from over 1,600 British energy generators. Most of these are small and independent.

It also invests in its own solar and wind farms and sources more than half of its electricity from wind farms.

Good Energy currently has over 200,000 customers and also says that its gas is carbon neutral (10% biogas and the remainder offset through carbon reduction projects).

It offers a dedicated tariff for EV drivers and plans to launch a time-of-use tariff for EV drivers in early 2021 which it says will be cheaper for drivers who can charge their vehicle outside of peak times.

Previously it has had a ranking in the annual Which? energy survey results. We were unable to gather feedback from enough customers this year to give it a score.
