Other energy brands A-M

Looking for a green tariff, a cheaper tariff or a more personal service? Here we tell you what you need to know about the smaller energy suppliers, listed alphabetically from A-M.

There are currently more than 50 firms you can buy your gas and electricity from in England, Scotland and Wales. That’s seven times the number that existed in the 1990s when the market was privatised, creating the six biggest suppliers British Gas, EDF, Eon, Npower, Scottish Power and SSE.

Many new energy firms have joined the market in the past few years, but these Big Six still dominate – 86% of households buy their energy from them, according to regulator Ofgem.

With such a choice of smaller energy firms, you can find one that suits you on price and ethos. These include firms focusing on providing 100% renewable energy, serving a specific geographical area, and not-for-profit firms. 

Scroll down to find out more about these smaller energy suppliers and what they have to offer - we've listed them alphabetically, from Affect Energy to LoCO2. Plus, we explain the pros and cons of choosing a small energy firm.

Better Energy 

A small new company based in Nottingham, Better Energy only supplies gas at this stage but has plans to supply electricity in the future. 

It's offering some very competitive gas tariffs and was in the top five cheapest gas-only deals for February 2016.


Launched in September 2017, Boost is Ovo Energy’s dedicated pay-as-you go energy brand.

Bristol Energy

Although based in Bristol, anyone in the UK can sign up to Bristol Energy’s tariffs. It’s one of the UK’s first municipal energy companies and is owned by Bristol City Council.

It invests in local renewable energy generators – although its fuel mix is currently made up of nuclear, coal, natural gas and renewables, in line with the UK average.

Bulb Energy

Bulb Energy offers 100% renewable electricity. In addition, its gas comprises 10% renewable gas made by anaerobic digesters fed with pig waste. 

Bulb's competitive tariff is cheaper than other renewable energy companies and cheaper than most of the Big Six. 

Our 2017 undercover investigation into energy companies’ customer waiting times found Bulb was the fastest to answer the phone to us when we called its customer services. It took just 27 seconds on average to speak with a human. Its live chat was slower, we got a human response more than two minutes slower than when we phoned.


Daligas only supplies gas to households, and offers a fixed and variable gas tariff. Its fixed gas tariff does not have an exit fee. 

This small firm is based in London.


E is a supplier of electricity and gas mainly to customers on pre-payment meters. It offers one fixed-price tariff.

In November 2017, E agreed with the energy regulator, Ofgem, to pay £260,000 in redress for failures to make its sales agents transparent or carrying out sufficient background checks on them. 

Ofgem found that sales representatives for Energy Watch UK presented themselves as an independent price comparison service, rather than revealing they worked for E. Ofgem said: ‘E’s management knew of these failures in 2014, but did not correct them until 2017’.

Formerly called GDF Suez, Engie’s a global energy supplier and generator – and owns a hydropower station in North Wales.

Engie committed to rolling customers onto its cheapest tariff (from May 2017) when their fixed deal ends. It calls this its ‘rollover promise’.

It also launched Engie Tracker in September 2017. The price of this tariff is updated every month to reflect the wholesale price of energy. So customers' bills can rise and fall. Engie says this 'provides fairness and transparency of pricing'.

All of Engie's tariffs have 100% renewable electricity. It also offers one with 100% renewable gas.

Green Energy UK

Green Energy UK sources all of its energy from green and renewable sources. None of its electricity comes from coal or nuclear power and it sources 100% ‘green’ gas from anaerobic digestion. It says it aims to make renewable energy mainstream and to offer competitive prices. 

It was the first energy supplier to launch a dual-fuel tariff, which uses a smart meter to charge customers different electricity rates depending on the time of day. Called TIDE, it costs just 4.9p per unit of electricity used between 11pm to 6am, but up to five times as much at peak times. It may suit you if you use lots of electricity at night, similar to Economy 7 or Economy 10 tariffs. 

None of Green Energy UK's tariffs have exit fees and its electricity-only tariff has no standing charge.

Green Network Energy

Originally an Italian gas and electricity company, Green Network Energy began supplying customers in the UK in 2017. It says it’s aimed at Italian expats, has a bilingual call centre and website, with headquarters in Rome.

How risky is it to choose a small energy firm?

The ultimate risk of choosing a small energy company is that it goes bust, which is what happened to in November 2016. But if your supplier does go under, you won’t be cut off. Instead, Ofgem appoints a replacement energy supplier.

This supplier doesn’t have to honour the prices customers paid previously but any credit balance you have built up will be protected. Read our advice on what to do if your energy supplier goes bust.

Small suppliers won’t suit everyone. If you receive the Warm Home Discount (a £140 payment to those who qualify for certain benefits) or want your supply to pay your feed-in tariff if you have solar panels, check the supplier offers these before you switch. Energy companies don’t have to provide these unless they have more than 250,000 customers – but many choose to.
