Yes. Standalone battery storage without solar panels is becoming one of our fastest-growing installations. It works by exploiting the price difference between cheap overnight electricity and expensive daytime rates.
How it works — You sign up for a time-of-use tariff like Octopus Go, which charges 7p/kWh overnight (typically midnight to 5:30am). Your battery charges up automatically during this cheap window. During the day, when standard rates are 24p+/kWh, your home runs on stored battery power instead of expensive grid electricity.
Savings — The price difference of roughly 17p per kWh adds up quickly. A 5kWh battery doing one full cycle per day saves approximately £310 per year. A 10kWh battery saves roughly £620 per year. Payback on a standalone battery is typically 6-8 years.
Why no solar? — Not every property is suitable for solar panels. North-facing roofs, heavy shading, listed buildings, or simply not wanting panels on your roof are all valid reasons. A standalone battery still gives you significant savings and reduces your reliance on peak-rate electricity.
0% VAT — Standalone battery storage qualifies for 0% VAT until 31 March 2027, even without solar panels. This saves you around 20% on the installation cost.
Future-proofing — If you decide to add solar panels later, the battery is already in place and ready to integrate.
