Cut Energy Costs This Autumn: Why Battery Storage Works With or Without Solar

4th Oct 2025

As the days grow shorter and the evenings draw in, many households start to feel the impact of Autumn. These longer nights mean that we’ll be relying on heating and lighting more often, which will lead us to much higher energy bills – and no one wants that! 

Of course, if you’re already equipped with solar panels, you’ll be less worried about your energy bills flying through the roof. But perhaps you didn’t know about this best kept secret that takes those money-saving benefits even further: a battery storage system.

By having a battery storage system you are essentially saving up the excess energy you haven’t used and keeping it for later. By storing excess solar energy produced during the day, batteries allow you to draw on that power in the evening when lights, heating, and appliances are needed most. Meaning much less reliance on the grid and less bills to pay.

 

But What If You Don’t Have Solar Panels?

Even if you don’t have any solar panels, you can still get a battery installed and watch your energy bills come down drastically.

So, how does that even work? Good question!

Even though you are still using energy from the grid, the time-of-use tariffs are what you may be unaware of. So, with our battery storage system you are able to store energy in off peak hours (cheaper energy) and use it in peak hours. Meaning more energy for less money. It’s a no brainer!

And as the nights are getting longer and colder, autumn is the perfect time to get a battery installed, because once winter arrives, those bills creep up fast. Especially once the festive season hits and guests come knocking, we know you’ll be turning the heating up and have the hot water running for longer! So, get your battery installed now and have peace of mind when those winter bills do come through.

Greater Energy Independence

As we all know, autumn can be unpredictable. One week brings crisp, sunny afternoons; the next delivers gloomy days and heavy rain. A battery storage system helps you stay in control of your energy regardless of the weather. 

Here’s an in depth breakdown of how battery storage works and how you can benefit from it:

  • During sunny spells your battery stores surplus energy for use after dark. 
  • In the evenings you can rely on stored energy to keep your home running without drawing as much from the grid. 
  • In a power outage your battery ensures your essential appliances and lighting stay on. 

This independence becomes especially valuable as the nights lengthen and demand for electricity rises across the country.
