Having now been with octopus energy for a year I cannot recommend them high enough. Their estimate and price for my usage/cost was spot on (unlike other suppliers who's estimate was low and bumped up my monthly charge soon after joining). My account visibility is clear (again unlike others I've used which seem to try and confuse), and i can get a refund frommy octopus account without having to jump through hoops if I find that my usage for a period is low. On top of that I get a chance to win credit to my account every month and can leavevsithout penalties whenever I want, but that I would. One of the best, and cheapest energy suppliers I've come across. Also if you use the link below as a recommendation, you get £50 credit to your account when you switch....can't be bad. Just use the following removing the spaces https:// share.octopus.energy / azure-dog-74 or go to their website and use azure-dog-74 as the recommendation code
