Most of our cost and incentive data is tailored for these regions, but the physics of batteries works the same everywhere! Here's how to adapt this guide:
- Look up your local electricity rate per kWh (and peak/off-peak logic).
- Check your local government website for solar/battery incentives.
- Use our calculator with your daily kWh usage—the sizing math is universal.

The UK government has significantly expanded support for home battery storage in recent years, driven by energy security concerns and net-zero targets. In 2026, UK homeowners have access to a range of incentives — from VAT exemptions to export tariffs — that can meaningfully reduce the cost of adding battery storage.
This guide covers every incentive currently available in the UK, who qualifies, and how to access them.
VAT Exemption: The Biggest Saving for Most Homeowners
The most universally available incentive for UK homeowners is the zero-rate VAT on battery storage systems installed alongside solar panels.
Since April 2022, the UK government has applied a 0% VAT rate (reduced from 5%, and previously 20%) to the installation of:
- Solar panels
- Battery storage systems installed at the same time as solar panels
- Battery storage systems installed separately (as of February 2024)
What this means in practice:
A battery system with an installed cost of £8,000 (excluding VAT) would previously have attracted £400 in VAT at 5%. At the old 20% rate, that would have been £1,600. At 0%, you pay nothing.
For a typical 10 kWh battery installation costing £7,000–£9,000, the VAT exemption saves £350–£450 compared to the previous 5% rate, and £1,400–£1,800 compared to the old 20% rate.
Who qualifies:
- Any UK homeowner installing a battery storage system (with or without solar panels)
- The installation must be carried out by a VAT-registered installer
- The battery must be for domestic use
How to access it: Your installer should automatically apply 0% VAT. If they're charging VAT on a domestic battery installation, ask them to confirm their understanding of the current rules. If they insist on charging VAT, consider using a different installer — this is a well-established exemption.
