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.
