Home battery install with Paul
Join us as we install a GivEnergy All-In-One home battery system
Installation day
Paul, based in Halstock, Dorset, was already charging his electric vehicle using a 7p/kWh off-peak tariff. After seeing how effective that strategy was, he explored how battery storage could help lower his overall home electricity bills - especially in a rural area prone to storms and regular power cuts.
After careful research, Paul chose Evoflo to install a GivEnergy All-In-One home battery system with a backup gateway. This setup allows him to store cheap, off-peak energy overnight and use it during the day - saving money and ensuring uninterrupted power during outages.
Although solar panels weren’t an option for his property, Paul was reassured that much of the UK’s overnight energy comes from renewable sources like wind. Since the installation, he’s cut his electricity bills by around 70% by discharging stored power during peak hours.
Paul chose Evoflo for our transparent pricing, fast turnaround, and GivEnergy-certified installation - which ensures he benefits from the full 12-year warranty. The system was installed quickly and with minimal disruption. Paul now confidently recommends Evoflo to anyone looking for a reliable, fuel-free energy storage solution for the home.

Customer testimonial
"Evoflo were professional, punctual, and clear. I now save around 70% on my energy bills and have vital backup power during the frequent power cuts we get in our area. It’s not just a nice-to-have — it’s peace of mind. A brilliant system, installed properly. Highly recommended."

Your guide to battery storage
What is Battery Storage?
Battery storage lets you store electricity so it’s available when you need it most. Whether you generate your own power using solar panels or want to save on energy costs by using off-peak electricity, battery systems give you greater control over how and when you use your energy.
In a home or business, they work like a backup supply - keeping the lights on, appliances running, and systems online even during a power cut. Unlike noisy, fuel-hungry generators, batteries are silent, clean, and efficient. They charge up when energy is cheapest or most abundant, then release it when it’s needed - whether that’s at night, during outages, or at peak times when electricity costs more.
From cutting bills to improving energy independence, battery storage is a smart, sustainable way to future-proof your home or business.
Benefits of batteries
Adding a battery system to your home or business premises provides a wide range of benefits:
-
Massive savings: Save on average £1,500 per year on your electricity bills. We help you move to a new intelligent tariff that uses cheap overnight energy and charges your batteries at off-peak times.
-
100% green energy: It'll feel good to know that your energy is coming from renewable sources from the grid. Your energy will be provided predominantly from offshore wind.
-
Be your own energy company: Have more control over your energy future, pull energy from the grid, your solar panels or even small wind turbines on your roof. Storage is the key to your energy independence.
-
No solar panels required: Our battery systems work in combination with cheap overnight tariffs as well solar panels. Plus you can also add your EV charger to the mix.
How does it work
Most homes and businesses can benefit from battery storage - and at Evoflo, we make the process simple from start to finish.
-
Consultation: It all starts with a call with Jules. We’ll walk you through the setup and check for essentials like a smart meter, available space for your hybrid battery, and safe, approved wiring. We’ll also discuss your energy usage, tariff options, and whether you'd like to explore finance plans.
-
Installation: Once booked, Dan, our experienced electrician and green energy expert will arrive with your pre-programmed hybrid battery. Installation typically takes 1–2 days. We can also install EV chargers and solar panels as part of a complete energy storage solution.
-
Connecting your tech: We connect your battery storage system and integrate it with any existing EV chargers or solar panels. Then we walk you through the app - showing your energy stats, configuration, and controls - all explained in a personal, 1-to-1 setup session.
-
Save money on energy: Finally, we help you switch to a green energy tariff from Octopus or British Gas. These give you 5–7 hours of cheap overnight electricity to charge your battery, so you can run grid-free during the day. If you're already with the provider, it takes about 24 hours to switch - a bit longer if you’re moving from another supplier.

FAQs
Can I get a home battery storage system without solar panels?
Yes — home battery storage without solar is becoming increasingly popular. Many homeowners now install batteries to take advantage of off-peak electricity tariffs. You can charge your battery overnight using cheaper electricity and use that stored energy during the day to lower your grid usage and energy bills.
Is it worth installing a battery just for overnight charging?
Definitely. Using a home battery for overnight charging on tariffs like Octopus Go or Shapeshifters allows you to buy electricity at rates as low as 7p/kWh, then discharge it when rates are much higher (e.g. 30p+). Even without solar panels, this strategy can cut your electricity bills by 60–80%.
Will a battery storage system protect me during a power cut?
Yes — if your battery system includes a backup gateway, it can automatically switch over and power your home during a power outage. This feature provides peace of mind by keeping essential circuits like lighting, fridges, and internet running during grid failures.
