Small energy companies A-M

Looking for a cheaper gas and electricity tariff, a more personal service or a firm that's a bit different? Here, we tell you what you need to know about the smaller energy suppliers, listed alphabetically from A-M.

There are currently more than 30 firms you can buy your gas and electricity from in England, Scotland and Wales. 

That’s many more than 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 most of the same big 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 and many have stopped trading amongst high wholesale prices in 2021.

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.

Affect Energy, as part of Octopus Energy, sells 100% renewable electricity, some of which it generates itself, some of which it buys directly from generators and some of which it backs with renewable energy certificates.

None of Octopus Energy's brands sell green gas.

Ampower

Ampower was set up in 2017 and stopped trading on 2nd November 2021. Its 600 customers are being moved to Yu Energy, chosen by energy regulator Ofgem.

Your gas and electricity supply will continue as usual and any credit you had on your account will be protected.

Yu Energy will email you in the coming days about your new account. While you wait:

  • take a meter reading
  • don't switch supplier until your account is set up.

Your new tariff will be called Protect Domestic Plan, which is limited by Ofgem's price cap. But it might mean you'll pay more than you did with Ampower.

See our FAQs on energy price rises and supplier failures.

Ampower said it used affordable green energy to help customers cut their carbon footprint and save money. 

It stopped taking on new customers in September 2021.

Bluegreen Energy

This small supplier closed on 1st November 2021. Its 5,900 customers are now supplied by British Gas. 

British Gas will be in touch in the next few days but says it could take four to six weeks to fully set up your new account. 

While you wait:

  • take a meter reading and submit it via your Bluegreen Energy online account
  • don't cancel your direct debit (British Gas will transfer it across)
  • don't switch supplier until your ne account is set up.

If you had credit with Bluegreen Energy it will be protected. But it can take two to three months to transfer it to your new account, British Gas says.

Your new tariff will be in line with the price cap.

If you were in debt to Bluegreen Energy, it will be in touch in the next few weeks.

British Gas Evolve

Launched in 2020, British Gas Evolve was a new brand from the big supplier. However in November 2021, it changed its name to British Gas.

British Gas explained that 'customers have told us that British Gas is a name they know and trust' and that nothing would change for customers besides the name. 

Your tariff, payments and log in details won't change. 

Customer services are 'digital-first', though there is a phone number if you need it.

Colorado Energy

Colorado Energy stopped trading on 13th October 2021. If you are among its 15,000 customers, you are being transferred to Shell Energy.

Shell will contact you in the coming days. If you are in credit, it will be protected and automatically moved to Shell Energy.

Your new tariff will be at the rates set by Ofgem's price cap. It will be a standard variable tariff, with no exit fees, which Shell Energy says is 'the cheapest we have available, given today's wholesale costs'. It will contact you with more information in a few weeks.

See Shell Energy's information for Colorado Energy customers.

Colorado Energy worked with letting agents to supply electricity and gas for tenants. It promised fair, affordable tariffs for all and straightforward pricing.

Co-op Energy

Co-op Energy says it provides good value, simplicity and transparency to customers.

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-op Energy is still responsible for attracting new customers though. 

Co-op 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.

Co-op Energy, as part of Octopus Energy, sells 100% renewable electricity, some of which it generates itself, some of which it buys directly from generators and some of which it backs with renewable energy certificates. Find out more about Octopus Energy's renewable energy.

Co-op Energy sells a Community Energy Tariff which matches electricity customers’ use with renewable power produced by 174 community generators. It costs slightly more than other tariffs so that generators are paid a fair price and to create a fund for other community generators.

Lizzie Heron, COO for Utility Solutions at Midcounties Co-Op told us: ‘Our aim is to grow community energy and help our members to access it simply.

'We have long been the leading supporter of community energy in the UK and have a team of people working on to support community generators... Taking this approach is more labour intensive than buying corporate PPAs but has much wider community benefits and is more effective than offsetting with REGOs so we’re committed to paying generators a fair price as well as offering our customers a tariff that’s competitive.'

Daligas

See Shell Energy's information for Daligas customers.

Daligas was a gas-only supplier which sold one variable tariff with no exit fees.

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

Ebico Living

Ebico Living 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.

Enstroga

Enstroga stopped trading on 29th September 2021. If you are among its 6,000 customers, your new supplier is Eon Next. 

It will contact you in the coming weeks about the changes. In the meantime:

  • take a meter reading

It's also worth downloading your statements or bills from your online account so that you have a record.

You will be put on the cheapest variable tariff based on average energy consumption, Eon Next says. The prices will be guaranteed until 31 March 2022.

When the transfer is complete you'll be able to switch supplier if you want to.

Read more about what to do if your energy supplier stops trading. See also our FAQs on energy price rises and supplier failures.

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

Entice Energy

Entice Energy closed on 25 November 2021. If you're among its 5,400 customers, you are now a customer of Scottish Power. 

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

You'll need to provide Scottish Power with direct debit details, your Entice Energy account number, postcode and up-to-date meter readings so it can set up your account. You can do that on Scottish Power's website.

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

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

Find out what to do if your energy supplier closes.  

Entice Energy was based in Mansfield and offered direct debit tariffs with online-only bills and account management. 

It said it offered ‘energy-free customer service’. You could 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 doesn't charge exit fees and says that customers are looked after by dedicated UK-based 'energy specialists'.

In October 2021, it took on the customers of Enstroga, Igloo Energy and Symbio Energy when the three smaller brands stopped trading.

Eon Next, part of the Eon Group, sells 100% renewable electricity tariffs, matched partly by renewable electricity that Eon generates, partly buying it directly from generators and partly by buying renewable energy certificates to match customers’ use with renewable power.

Proportion of renewable electricity sold to domestic   customersGenerates renewable electricity?Buys renewable electricity directly from generators?Proportion of customers’ renewable electricity matched by REGO certificates?Generates or buys directly from fossil fuels?Sells green gas?
81.9%Yes (3%)Yes (33%033% and 20% backed by GoOsNoNo

Proportion of renewable electricity according to Eon’s 2020/21 fuel mix. Other responses based on information provided by suppliers in August and September 2021.

Some 81.9% of Eon’s electricity fuel mix is renewable, 1.8% is nuclear and the remainder comes from fossil fuels. 

The renewable electricity it generates is from biomass, which Eon says is fuelled by responsibly-sourced waste and recycled wood. Eon’s Sheffield site uses locally-sourced waste wood which otherwise would have gone to landfill. 

Eon also buys around a third of the electricity used by its customers from renewable generators. It says it helped generate many of its supply sites over the last decade. 

This doesn’t match every customer’s use though – a fifth of its electricity is matched with renewable power generated outside the UK, in Europe, using Guarantees of Origin (GoOs).

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'. It offers a tariff specifically for electric vehicle drivers.

A small proportion of the overall electricity ESB Energy sells is matched with renewable sources. It generates some renewable electricity and also buys renewable energy certificates to match its customers’ use.

Proportion of renewable electricity sold to domestic   customersGenerates renewable electricity?Buys renewable electricity directly from generators?Proportion of customers’ renewable electricity matched by REGO certificates?Generates or buys directly from fossil fuels?Sells green gas?
14%Yes (ns)No100%YesNo

Proportion of renewable electricity according to ESB Energy’s 2019/20 fuel mix. Other responses based on information provided by suppliers in August and September 2021.

ESB Energy operates onshore wind farms in Durham, Devon and Mynyyd d Betws. It has stakes in offshore windfarms too and is involved in building more. But the output of these isn’t directly linked to the electricity that its customers use. 

It also operates a combined cycle gas turbine plant. This uses fossil fuels. ESB says it’s one of the most efficient thermal plants in the UK.

ESB Energy doesn’t sell green gas.

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

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.

Some 10% of the gas it sells to homes is matched with green gas generated from a mix of food waste and energy crop biomethane. It says it only buys this from farms which are acting sustainably. 

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

Good Energy has joined the UN’s Race to Zero campaign and committed to halving its emissions by 2030 and reaching net zero by 2050. It says it already meets this target by offsetting all emissions it can’t avoid.

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.

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.
