Flexibility trading
Get paid to support your local grid
Flexer puts your battery, solar and smart devices to work in local flexibility markets — earning you money for helping your network operator keep the grid balanced, on top of anything your tariff pays.
Beyond your meter
Your local grid pays for flexibility — most homes never see a penny
Network operators pay for help managing their local grids: soaking up excess wind and solar when there's too much, easing the strain when demand peaks. Until now that money has gone almost entirely to large industrial sites. Homes with batteries, EVs and heat pumps can do the same job — they've just never had a simple way in.
A typical day
Solar generation vs. grid prices
Peak prices hit later in the day — exactly when your battery needs to kick in, but most systems aren't smart enough to plan for it.
How Flexer works
Your home, trading in local flexibility markets
Finds the opportunities in your zone
Flexibility is local: network operators publish paid opportunities for specific zones and time windows. Flexer matches your home to its zone and enters it into the markets it qualifies for, including NGED and LocalFlex.
Trades in both directions
When the network needs headroom, Flexer can discharge your battery or pause EV charging. When there's excess green energy to absorb, it charges your battery or runs your devices instead. Your home earns either way.
Pays for being ready — and for delivering
Flexibility contracts pay an availability fee for being on standby during a window, plus a utilisation fee when your home actually responds. Flexer handles the bidding, dispatch and reporting automatically.

Common questions
How is Flexer different from Shîfter?
Shîfter optimises your own energy use against your tariff, cutting your bill. Flexer earns additional money from your local network operator by trading your home's flexibility in their markets. They're designed to work together.
What exactly am I paid for?
Two things: an availability payment for having your home on standby during a flexibility window, and a utilisation payment when your home actually delivers — by discharging, pausing charging, or absorbing excess energy.
Can every home take part?
Flexibility markets are local, so it depends on your network zone and what your operator is currently procuring. The estimator checks your postcode and shows the markets your home qualifies for.
Will trading disrupt my home?
No. Flexibility windows are limited — never more than eight hours per opportunity — and your home's own needs always take priority. Most of the time you won't notice anything at all.
