The Independent reader offer: 5% off an Octopus solar & battery installation
Smarter, cleaner home energy — with an exclusive saving when you make the switch for spring time.
Solar and batteries are a smart investment you can make today to cut bills and take control of your energy.
For a limited time, readers of The Independent can get 5% off the final cost of a solar & battery installation with Octopus Energy. Offer ends 17 April 2026.
Why solar and batteries?
Solar panels generate clean electricity from daylight — even on cloudy days — helping you power your home with less energy from the grid.
Add a home battery and you can store excess solar energy to use later, meaning cheaper power in the evenings and less reliance on peak-time electricity prices.
