Axle Energy – Earn £1/kWh from Your Home Battery (£10 a Month Minimum)

Overview

Axle Energy is a UK virtual power plant (VPP) operator that pays home battery owners for exporting stored energy when the grid is under stress. Connect a compatible battery through the link on this page and you earn £1 per kWh exported during Axle's scheduled grid events, with a guaranteed minimum of £10 a month while you're connected.

How to Claim

1. Click the link on this page to open the Axle Energy sign-up page.
2. Upload a recent energy bill (Axle reads your meter references from it) and connect your battery's cloud account via the guided API-key steps — about 5 minutes.
3. Axle bids your battery into the day-ahead market and schedules export events, typically around an hour long and roughly four times a month, with about 20 hours' notice.
4. Earnings accrue in your Axle account; withdraw to your bank once you have £10 or more.

Requirements

• A compatible home battery — currently AlphaESS, Sigenergy, FOX ESS, GivEnergy, SolaX, Solis and SolarEdge systems, with more brands being added
• A UK smart meter (verified during sign-up)
• Works with any energy supplier, tariff or Feed-in Tariff arrangement, and alongside Home Assistant or third-party scheduling

Important Terms

• No contract — opt out at any time and skip any individual event in the app
• The service is in beta, so rates and the £10 minimum can change; most users save on their bill but Axle doesn't guarantee it
• Payments are by bank transfer with a £10 minimum withdrawal
• Works alongside existing export payments such as the Smart Export Guarantee
• Axle operates within your battery manufacturer's specifications, so your warranty is unaffected

Tips

• Events run automatically in the background — once connected there's nothing to do
• Grid events can coincide with your supplier's own saving sessions, letting you earn from both at once
• Check your battery brand is on the compatibility list before you start
