Customer reviews
What homeowners say about us
"They had my battery and inverter installed within four days and the cheapest I could find on the market. The engineer was very helpful and polite, made a fantastic job, was very clean and tidy and set everything up on my phone."
"They were fast and explained how the system worked really well. Nothing went wrong. The system is already reducing my energy bills when used with the Octopus Agile tariff, and I have my own power supply in case of blackouts."
"I had a new inverter and two batteries fitted. The fitter came when expected, was pleasant and professional, and after completing the work he set up the app on my phone. The system is working well and I am very satisfied."

Common questions
Straight answers before you commit
Can't see your question? Call 0330 043 1174 or message us on WhatsApp and a real person will answer.
Do I need solar panels to benefit from a battery?
No. Many customers fit a battery on its own and charge it overnight on a cheap tariff, then run the house on stored power during peak hours.
How quickly can you install?
Most battery installs are completed within days of your order and take a single day on site — no scaffolding, no roof work.
What warranties and guarantees do I get?
Every installation comes with our standard 5-year workmanship warranty. The battery and inverter are covered by their manufacturer's warranty, which varies by brand and model; we confirm the exact terms in your quote.
Can I spread the cost?
Yes. Finance is available through Kanda, an FCA-regulated credit broker. Credit is subject to status.
