Can I add a battery to my existing solar panels?

FAQs
Battery storage questions
Straight answers to what homeowners ask us most. Anything else, just ask.
Do I need solar panels to have a battery?
No. A battery can charge from the grid on a cheap overnight tariff and power your home at peak times. Adding solar later increases the savings.
Is there VAT on batteries?
No. Since February 2024, batteries installed in homes in Great Britain are zero-rated for VAT, including batteries added to an existing solar system. The relief runs until 31 March 2027.
What size battery do I need?
Most homes choose between 5 and 15 kWh. We size it from your evening usage, any solar you have, and your tariff.
Where can the battery go?
Common spots are a garage, utility room or a suitable outside wall. Each battery has rules on temperature and clearances, and we check these during the survey.
How long does installation take?
Most battery installs take one day, with a short power-off while we connect it.
