What is solar battery storage?

Solar battery storage is a battery unit connected to your solar panel system that stores surplus electricity generated during the day so you can use it later instead of exporting it to the grid or drawing expensive electricity back from the grid after dark.

Do I need solar panels to get home battery storage?

No. Home battery storage can be installed as a standalone system, charging from the grid on a cheap overnight tariff and discharging when electricity is more expensive. It is also solar-ready, so panels can be added later if you decide to.

How much does home battery storage cost in the UK?

Cost depends on the battery brand, usable capacity, and whether it is installed alongside solar panels or as a standalone system. Get in touch with Apex Doma for a free, no-obligation quote based on your household usage and property.

Is there VAT relief on battery storage in the UK?

Yes. Since 1 February 2024, home battery storage installed in Great Britain qualifies for 0% VAT under HMRC VAT Notice 708/6, whether it is installed with panels or as a standalone system, and whether it is a new installation or added to an existing solar array. This relief is due to run until 31 March 2027.

Battery Storage Installation

Available as a standalone solution or used to store self-generated energy from solar, battery storage will allow you to save money on your energy bills from month one by accessing cheaper night-time energy tariffs.

why battery storage?

01 Charge Up Your Battery

You can use self-generated solar energy, or charge at a cheaper rate from the grid during the night.

02 Use at Peak Times

This reduces your electricity bill by using the power that you’ve got stored, rather than the expensive electric from the grid.

03 Feed Into The Grid

Anything you don’t need, you can sell back to the grid. Schedule charging & discharging for maximum benefit.

working with market-leading manufacturers

There’s lots of battery storage solutions on the market, we only work with brands we would be happy to put in our own homes.
We are proud to be approved installers for both Tesla & GivEnergy, bringing you the best technology, warranties and aftercare service on the market.

Tesla Powerwall

Perfect if you get power outages and want to operate off-grid.

Sigenergy SigenStor

The most flexible and scalable solution with bi-directional EV charging.

Pair with solar and recharge

The battery will be charged with your excess power during the day, storing all that energy that isn’t being used by your home. You can then use the battery to run your home during the evening or at night, using up that stored energy without taking anything from the grid. You can even discharge to the grid at peak times for financial incentives!

The best bit, it all happens automatically. Intelligent battery software uses algorithms to calculate when to store or discharge energy. This also works with solar, calculating when to use, store or sell the energy back to the grid for maximum cost savings.

Can I add a battery onto my existing system?

Of course! The only thing you might need to upgrade is your inverter.

If you have an existing system that benefits from the government’s old Feed In Tariff (FIT) scheme, then you can go on taking advantage of that, your FIT payment will stay the same because you’re paid for all of the energy you generate.

Protecting your Feed-In Tariff

To protect these profitable payments while also taking advantage of battery storage, we recommend having what we would call an AC-coupled system. We leave the existing system exactly as it is and put a second inverter in to manage the charging and discharging of the battery. By installing this way, maximum energy continues to pass through the FIT-registered meter, giving you the highest possible income from the scheme.

don't just take our word for it...

Had a battery fitted, add-on to our previously installed solar panels by another company. Apex Doma were very professional, explained the process clearly, provided the necessary information for me to make a decision, and when I decided to go ahead, they fitted the battery within 2 weeks of the consultation visit. So far, very happy with the battery performance.

The equipment itself is fantastic, so easy to use and really good quality. Adam and the team really take the time to explain how to set up and use the equipment. I am switched over to Octopus and along with the Give Energy app, we may only be in November, but the amount of solar I am getting and the difference already is huge!

I would highly recommend talking to Ian, Adam or anyone else in the team. Everyone is really knowledgeable about the systems they install. Talking to Ian helped me understand the bigger picture and how everything works in the system and the best way to utiliise the system based on my usage.
