Battery storage is fast becoming one of the most exciting home energy upgrades available in the UK. Whether combined with solar PV panels or used as a standalone AC-coupled system, batteries offer homeowners greater energy control, lower bills, and a big step toward energy independence.
Here are 10 compelling reasons to consider battery storage — with or without solar panels:
1. Use More of Your Own Solar Energy
If you already have (or are installing) solar panels, adding a battery lets you store excess daytime energy for use in the evening or during peak times — instead of sending it back to the grid.
💡 Fact: Without a battery, most UK homes export around 50–60% of the solar energy they generate!
2. Save Money by Avoiding Peak Rates
Battery systems can help you avoid using expensive peak-time electricity from the grid. Some smart batteries even charge up during off-peak times and discharge during the day to lower your bills.
💷 Pairing with a time-of-use tariff (like Octopus Agile or Intelligent Octopus) can cut your energy costs dramatically.
3. Works Even Without Solar
Don’t have solar? No problem. A standalone battery system can still charge from the grid when electricity is cheapest, and power your home when rates are highest — ideal for households looking to reduce costs and carbon.
4. Protection from Power Cuts
Many battery systems offer backup capability, meaning they can keep your lights, Wi-Fi, and essentials running during grid outages — giving you greater resilience and peace of mind.
🔌 Some systems allow you to run critical circuits even when the grid is down.
5. Get Paid for Storing Energy (Smart Grid Participation)
With grid-balancing programs like Octopus Powerloop or National Grid’s Demand Flexibility Service, your battery can actually earn money by storing or releasing energy at times that help the grid.
💸 Some homes have earned £100–£200 per year just by allowing their battery to be part of these schemes.
6. Reduce Your Carbon Footprint
By storing and using clean solar energy or charging your battery during green grid times (overnight, for example), you’re reducing your home’s reliance on fossil fuels and lowering your emissions.
🌍 The UK’s electricity is cleanest at night — pairing battery storage with green tariffs can make your home low or zero carbon.
7. Maximise Your SEG Returns
Solar homes with a battery can still benefit from the Smart Export Guarantee (SEG). By timing your exports when rates are higher or storing energy when it’s not needed, you can optimise your income and usage.
8. Future-Proof Your Home
Energy costs and climate policies are shifting fast. Installing a battery now prepares your home for a future of smart, flexible energy — including electric vehicles (EVs), dynamic tariffs, and home automation.
🔋 Many batteries are modular, so you can expand capacity over time as your needs grow.
9. Quiet, Compact & Low Maintenance
Home batteries are sleek, reliable, and surprisingly compact. Most require little maintenance and can be installed indoors or outdoors, depending on the model.
📦 Popular options like Tesla Powerwall, GivEnergy, or SolarEdge Home Battery all come with 10-year warranties.
10. Zero VAT – Save 20% Instantly
As of 2024, standalone home battery systems are eligible for 0% VAT, just like solar panels — making them more accessible and affordable for UK homeowners.
✅ That’s an instant 20% saving on installation costs — with or without solar.
Is Battery Storage Right for Your Home?
Whether you already have solar panels, are planning a full system, or simply want to take more control over your energy use, battery storage is a smart, future-ready choice. From reducing bills and carbon to staying powered during outages, the benefits are real and growing fast.
