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 70 firms you can buy your gas and electricity from in England, Scotland and Wales. That’s more than 11 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.

Though the Big Six energy firms still dominate the market – more than 80% of us use their services – there's 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.

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

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

In May 2018, Ofgem alleged that E, along with Economy Energy and consultancy firm Dyball Associates, breached competition law. Ofgem said the two companies agreed not to target each others' customers in face-to-face sales for several months in 2016. It claims this 'prevented, restricted and distorted competition amongst energy suppliers'.

E was also in trouble with the regulator in November 2017. It agreed to pay £260,000 in redress for failures to make its sales agents transparent or to carry 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’.

Energy SW 

A new entrant in the energy market, Energy SW is only available to people living in properties owned by social housing consortium Advantage SW. Energy is supplied by Ovo Energy, as is customer service and billing.  


When Engie started supplying homes in March 2017, it was the largest company to enter the UK domestic energy market in 15 years. It now supplies around 75,000 homes.

Engie committed to rolling customers onto its cheapest equivalent 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.

Our undercover call waiting investigation in September 2018 found that Engie was one of six firms to answer the phone in less than a minute on average. It didn't respond within two weeks to any of the emails we sent, however.
