Frustrated trying to find information about Economy 10 tariffs?  Me too…. which is why this site is here.  Welcome!

This site is a collection of information that I’ve gradually built up over the years of being on an Economy 10 electricity tariff (also known as ‘Heatwise’), and felt it might be useful to share it with the wider world.

I also ask the community to contribute their info on Economy 10 prices and tariffs, as well as my own conversations with suppliers, and will produce a summary highlighting the best E10 deals around.  Economy 10 prices don’t appear on price comparison websites, so I’ll be publishing them here on the blog.

Update:  Latest Economy 10 Prices – May’17

Update:  EDF 20-25% price hike. Comparison with iSupply Energy. Regional pricing.

Update:  Calling all E10 users – submit your prices

Update:  Sunamp case study

Update:  This site is independent – feel free to buy me a coffee to keep me going 🙂


Feel free to send me feedback directly using the form (see below), or leave a comment on any of the other pages.

Cheers, Mark
