How does it work?

How a battery saves you money:

  1. Charge overnight. Your battery fills up automatically when electricity is cheapest, on a time-of-use tariff's off-peak rate.

  2. Discharge at peak. Instead of drawing expensive daytime electricity from the grid, your home runs on stored battery power.

  3. EquiVolt+ manages it. Our subscription service handles the charge and discharge cycles and looks after the battery's long-term health, so there's nothing for you worry about day-to-day.

Note: EquiVolt+ is an optional service. You own the hardware from day one and can choose to self-manage the system if you prefer.

Why EquiVolt?

EquiVolt batteries charge on cheap overnight electricity so you can save money effortlessly every day. No complicated appliance timers to manage yourself or juggling your schedule to get the best rate. A battery that simply pays for itself by buying electricity for you at the right time of day.

We're also building something bigger. A network of home batteries makes more efficient use of storage than a handful of idle grid-scale batteries, and helps the grid absorb more renewable generation instead of curtailing it.

It's a win-win-win:

  • You get lower energy bills

  • The grid becomes more stable as thousands of home batteries help balance supply and demand

  • The UK's renewable energy transition speeds up

We started EquiVolt because high-quality battery storage shouldn't be limited to people who can afford expensive systems, we want to make the energy system and green transition equitable for all.

  • "We have been on the pilot scheme with Equivolt, and are very happy with the whole experience of having a house battery that is managed by them. We do not notice any effect on how our appliances work, but when we look at our smart meter during the day we see virtually no power being used from the grid. The Equivolt+ management system works really effectively, so we don’t have to do anything ourselves to get the best use out of our battery. Our electricity bills have halved, and monitoring the details given by our electricity provider shows us that nearly all the electricity we use is during our off peak spell."

  • "Everyone should have one! Charging up a battery at cheap overnight rates and then running my house during the day using that electricity, saving paying at peak rates, just makes so much sense. And with every price rise, the logic just gets more compelling. I'd been looking at this for some time, but EquiVolt's pricing makes it a no-brainer. The company is run by extremely professional, passionate and knowledgeable people. No sales pressure - just enthusiasm! The installation was super easy, and everything worked just as it should immediately. Highly recommended!"

    —John

  • "Highly recommended Following an informative & reassuring site survey, we were very impressed by the company's vision, it's products and by the absence of any sales pressure. The Equivolt team carried out our installation exactly as planned within the anticipated timescale. They worked efficiently with minimal disruption, kept us informed at each stage, and removed all waste & packing materials upon completion. We have received an excellent follow up service with regular system reports together with rapid, helpful responses to our enquiries. We remain very happy with our decision to purchase an Equivolt system and can highly recommend this company."

    —S&E

  • "Excellent service and a great product. What a fantastic company! A true vision to support the National Grid whilst delivering a good level of saving on electricity bills. The installation of our battery was extremely smooth, disruption free, and two months in, we have had no issues- just half price electricity and it would be even less without the standing charge. Rob and Tom are experts in this field and can answer every question you might have with integrity, as they have thought through every possibility. Highly recommended."

  • "This was something I had been thinking about for some time given I'm now on my third EV and just retired, so I was pleased to see this company had the same idea! I was lucky enough to get on the pilot scheme even though I have a 3-phase supply, but Tom thought it would work given I have one heavily loaded phase (new kitchen). I have to say the guys were excellent from start to finish, they even put up with my (probably excessive) questions about their system! As an example of the "above and beyond" after setting an installation date, on them receiving my battery and testing it themselves, they found a fault. Rather than delay installation, the installed the battery from their own house, then swapped it over a short time later when the replacement arrive - beat that for customer service! Their control software seems excellent, and they were happy to go through the information they gather and use and like my EV it is "over the air" updates. A small company that deserves to grow and I cannot recommend them enough."

  • "Equivolt has provided us with a fantastic product for a very reasonable price and with a level of customer service which is unprecedented in my 70 years. We are not a typical Equivolt customer but they were happy to tailor what they do to blend with our existing set up of solar, EV and heat pump. They have provided us with a 15KwH Fogstar battery, compatible with our inverter, which will keep us off peak all year round. We generate around 4.5MWh from solar but have a shortfall in winter, late autumn and early spring so we will now be charging our new battery overnight on our EV tariff during these periods. Even without solar, charging overnight on a cheaper tariff all year round and then running your house from the battery makes so much sense. If you're on an EV tariff it makes total sense. Providing domestic battery storage together with an operating system and excellent customer support is what Equivolt do and I can't recommend them highly enough. I don't just endorse this company but would happily personally invest in it. Special thanks to Rob Mitchell-Williams for taking us on and providing a top class product and service."
