Axle Energy is a UK flexibility company that connects compatible home batteries to its virtual power plant. During short Axle Energy events, participating batteries export electricity when the grid needs additional support, and homeowners are paid for the energy supplied.
You can sign up through my Axle Energy referral link to receive a £25 joining bonus. Axle currently advertises earnings of £1 per kWh exported during events, with a guaranteed minimum payment of £10 per month.

How Axle Energy works
Axle connects compatible home batteries to its virtual power plant. When the UK electricity grid is under stress, your battery can export stored energy to help balance supply and demand. In return, you get paid for taking part.
Axle says grid events are typically around 60 minutes long and happen roughly four times per month.
The setup is designed to be simple:
- Sign up and connect your battery
- Take part in grid events
- Get paid for exported energy
From what Axle says, setup takes around five minutes. Once connected, it runs in the background unless you choose to opt out of events.
How Do Axle Energy Events Work and What Can You Earn?
Axle Energy events are short periods when extra electricity is needed by the grid. Axle schedules an event through its service and temporarily instructs connected batteries to export. You can see upcoming events and choose to skip an event if it does not suit you.
Axle says the current offer includes:
- Guaranteed minimum payment of £10 per month
- £1 per kWh exported during grid events
- No contract
- Opt out at any time
Axle says many participating homes earn more than the guaranteed minimum, depending on the number of events and the amount exported.
Control and battery protection
One of the obvious questions with any battery flexibility or virtual power plant scheme is how much control you give up.
Axle says you stay in control and can skip an event in the app if you do not want to take part.
And says its software operates within supported manufacturer limits and is designed not to affect your battery warranty.
This may make the service more appealing if you want to earn from your battery, but do not want to hand over full control.
Tariff compatibility
Axle says the service is compatible with most tariffs, including standard and time-of-use tariffs.
However, it is not compatible with tariffs that directly control your battery.
If you are already using a smart tariff or another battery optimisation service, it is worth checking the details before signing up.
Axle Energy and GivEnergy: Battery Support and Premium Fees
If you have a compatible GivEnergy battery, signing up to Axle Energy could help cover the cost of your GivEnergy Premium subscription.
Axle connects home batteries to its Virtual Power Plant, allowing your battery to support the grid during peak demand or grid stress events. In return, Axle offers a guaranteed monthly payment, and for GivEnergy users, Axle says it will cover the cost of the GivEnergy Premium subscription as part of joining the service.
This is especially useful now that GivEnergy Premium is needed for some remote access, data analysis, automation and optimisation features. GivEnergy’s own FAQ confirms that basic local monitoring and control remain available without a subscription, but the paid tier is aimed at users who want the more advanced cloud features.
You can check the official GivEnergy Premium FAQ here:
So, if you were already considering paying for GivEnergy Premium, Axle Energy may be worth a look. You could get the subscription cost covered, earn from grid events, and still keep control of your home battery.
Axle Energy Works With Predbat
Axle Energy can also work alongside Predbat, the home battery prediction and automation system. Predbat can include upcoming Axle grid events when planning when your battery should charge, hold energy or export.
This means you can continue using Predbat to optimise your battery around electricity prices, solar forecasts and expected household use, while also preparing for Axle events.
You can read more about how it works and use my Predbat referral link here: [Try Predbat]
I also spoke to Predbat creator Richard Eyres about how it works, battery automation and its integration with Axle Energy. You can watch the full interview on YouTube or listen on the Energy Unwrapped podcast.
Which Batteries Does Axle Energy Support?
The easiest way to check is via Axle’s own page here:
https://vpp.axle.energy/faq
That will always have the most up-to-date list of supported batteries and requirements.
At the time of writing, Axle lists support for:
- FoxESS
- GivEnergy
- Sigenergy
- SolaX
- Solis
- SolarEdge
Support may expand over time, so it is worth checking the official page before signing up.
Is Axle Energy worth it?
If you already have a compatible home battery, Axle looks like an easy way to earn a bit of extra income from it. The guaranteed monthly payment gives you a baseline, and the ability to opt out of events keeps you in control.
For me, the main attraction is that this is not just about export rates or arbitrage. It is about using battery storage to support the grid at the times it actually needs help.

Axle Energy FAQ
What exactly is Axle Energy?
Axle Energy operates a virtual power plant that connects compatible home batteries and other energy devices to electricity markets. It can control participating batteries during selected events to help balance electricity supply and demand.
How much can I earn with Axle Energy?
Axle currently advertises a guaranteed minimum payment of £10 per month and a payment of £1 per kWh exported during eligible grid events. Actual earnings above the minimum depend on the number of events and how much your battery exports.
Is there a contract?
Axle says there is no fixed contract and that customers can leave the service. Check the current terms before joining.

Under Axle’s current offer, eligible customers still receive the advertised £10 monthly minimum even when event earnings are below that amount.
