Real members share how equiwatt helps them save money, cut carbon and earn rewards.

This app is great, I signed up during the winter for the DFS events but have stayed on since. It's helped out reducing my energy usage and I can cash out vouchers to reduce the cost of my food shop – win win!

This is a really amazing app to help you become more accountable for energy use and get rewarded in the process. It’s a slow burner but worth it in the end.

I have earned 5000 points which I have redeemed for £50 worth of vouchers from well-known national and international retailers. Make way for a cleaner grid with equiwatt!
DT Dudkamp Google Play Review
A low maintenance, rewards app for smart meter users. Really easy to navigate and use. They notify of 'equivents' and all I have to do is opt-in and I get rewarded points for using less electricity and saving energy as they happen.
Sam M Google Play Review
Really easy app to use. Just indicate that you are participating, reduce energy usage for an hour, and get points that can be swapped for shopping vouchers. Reward for very little effort.
Julia Baron Google Play Review
I've been a member of the Equiwatt community for just over 2 years and have seen really positive changes to the app in that time. The app runs in the background with little participation from me yet reduces my carbon footprint.
Liz Kershaw Google Play Review
Great app, helps make you a little bit of money, whilst saving money on usage, and the rewards can help grow the savings via WiFi switches.
Richard Google Play Review
Great app, great company. In just under 2 years I've earned £120 in Amazon vouchers for doing very little! The app is clear and intuitive.
Chris Greenwood Google Play Review
No-brainer – earn money by using less. This app is a clever technological link between using less energy and being rewarded for this.
TriniKathy App Store Review
Brilliant app. Helps you actually see how much energy you are using and helps you cut down through the day from using too much energy hence saving you money.

This app helps to reinforce healthy energy saving habits and gain reward at the same time. What is not to like?
Gregor McAbery App Store Review
It’s easy to take part in power down events and you can accumulate points to exchange for gift cards. I’ve had a £15 Costa gift card so far.
