The UK’s first energy smart switching app. Track the whole market and switch to a better deal with just a few taps. Set your preferences, receive personalised alerts and never miss a saving. Managing your electricity and gas bills with Voltz is easy. Brought to you by Simplify Digital and DixonsCarphone PLC


"...utterly goof-proof and takes about five minutes to do"
- Metro

"...aimed at the three-fifths of Brits who have never switched supplier..."
- Evening Standard

"It even shows how many complaints have been logged against suppliers..."
- The Mirror

Voltz saves everything down: When you switched, who you switched to, the name of the tariff, your regular payment amount, the rates you are billed on, the terms and conditions – it is all there at the tap of a finger. Voltz knows when your current deal expires and tells you way in advance about the cheapest alternative, so you don't accidentally end up overpaying for an expensive standard rate tariff.

There is no app that can do all of this so well and Voltz is FREE. Use Voltz to switch and you will never overpay for energy again.

What does Voltz do?
Voltz makes it incredibly easy to compare electricity and gas and always get the best deal for your energy. Spend only a few minutes to create an account, tell us about your energy usage and switch. Get alerts on your phone when it is time to switch again. Our comparison service tracks the tariff you are on, alerts you with a message to your mobile when we find something better and lets you switch again with a tap of the finger.

How does Voltz work?
Tell us where you live and how much energy you use. You can set a savings goal, a fixed date reminder or let us periodically sweep the market for you. Best deal alerts are sent to your mobile phone for maximum convenience. Swipe the alert, review the deal and tap to switch. Voltz automatically updates your account with your switch info and continues to scan the market in the background.

How is Voltz different from a comparison website?
Our service is about finding you the best energy deal without doing any work. You tell us once about your energy details and we will always keep you informed about the cheapest deals in the market. Voltz makes it possible to switch with just a tap of the finger and without providing any extra information – and you don’t have to be in front of a computer to do it.

Are you impartial?
Absolutely! We show you everything you need to know about your current and future tariff plan, including exit fees. We keep track of all your past switches, so you can use Voltz to remind yourself what deal you are on now and before.

Can I switch to every supplier and tariff in Great Britain with you?
Yes you can, and we are the only comparison service that lets you do this. You can switch electronically to most deals. When we cannot offer electronic switching we let you ring the supplier directly, provided the supplier has a published phone number. Either way, we put you straight through to the supplier and onto the cheapest deal.

How long does it take to switch?
Switching should take no more than 17 days. It is not yet possible to switch supplier instantly.

Does it cost money to switch?
No, Voltz is FREE and always will be FREE.

Well, that was easy!


I've just done my first energy supplier switch using this app. Goodbye Scottish Power (you were OK) and hello Green Energy from Bulb Energy for >£100 saving per year! Voltz made the whole process quick and easy (assuming the deal goes through without a hitch) and made the search results easy to compare and filter.

Fantastic app!


Used this app to change twice now and both times doubled checked with someone in the know to make sure it is coming up with the cheapest deal for me and both times it has come up trumps.

Great help

Martin North

Works really well, have switched a few times now.
Would be an improvement if the app could hold the info and scan for more than one address at once.
