How Flex covers the £7
The grid has to match supply and demand every second. When it’s tight, grid operators pay to have demand moved.
Your home and hot water tank already hold heat, so we can nudge when your heat pump runs without you feeling it.
Questions
Will it work with my heat pump?
If you have a Samsung, Vaillant, Mitsubishi Electric or Daikin air-to-water heat pump that you control in SmartThings, myVaillant, MELCloud or Onecta, yes.
Do I need extra hardware?
No. It connects to your heat pump over the internet.
Can I still change things myself?
Yes. Boost or turn down whenever you like.
What happens after the free month?
Join Flex and your £7 a month is covered, so you pay £0. Or choose Classic at £7 a month. Cancel before then and you pay nothing.
What is the difference between Flex and Classic?
The app is the same. On Flex, we nudge when your heat pump runs to help balance the grid, and that covers your £7 a month.
Will my home be colder on Flex?
No. We keep to your heating and hot water schedules and the temperatures you set.
Will my electricity bill go up on Flex?
It’s unlikely. A very small rise is possible, and the £7 a month that Flex covers is more than that.
Can every home join Flex?
Flex needs a smart meter and your home to pass our meter checks. If your home doesn’t qualify, Havenwise is £7 a month.
Can I leave Flex?
Any time. Contact support and we’ll move you to Classic at £7 a month.
Most users pay nothing.
