What is the 0% VAT Policy?
Since 1st April 2022, the UK government has applied a 0% VAT rate to the installation of energy-saving materials (ESMs) in residential properties. This policy was made permanent in the Spring Budget 2024 and applies to solar panels, battery storage systems, and heat pumps.
Who Qualifies for 0% VAT?
The zero VAT rate applies to:
- Residential properties: Homes, flats, and residential conversions
- Charities: Buildings used solely for charitable purposes
- Age-related residential accommodation: Care homes and supported living
Important: Commercial properties do NOT qualify. Businesses, offices, factories, and rental properties managed as businesses are subject to standard 20% VAT.
What's Covered Under 0% VAT?
The following energy-saving materials qualify:
- Solar photovoltaic (PV) panels and mounting systems
- Inverters (string inverters, micro-inverters, hybrid inverters)
- Battery energy storage systems (when installed with or after solar)
- EV charging points (when installed with solar)
- Installation labor and associated materials (cables, isolators, consumer unit upgrades)
- Scaffolding and safety equipment hire
How Much Can You Save?
The savings are substantial. Here's a comparison:
| System Size | Cost at 20% VAT | Cost at 0% VAT | Savings |
|---|---|---|---|
| 3kW Solar Only | £6,000 | £5,000 | £1,000 |
| 4kW Solar + 5kWh Battery | £10,800 | £9,000 | £1,800 |
| 6kW Solar + 13.5kWh Battery + EV Charger | £19,200 | £16,000 | £3,200 |
Common Misconceptions
Myth 1: "Batteries don't qualify for 0% VAT."
Reality: Batteries installed alongside or after solar PV qualify for 0% VAT. Standalone batteries (without solar) are subject to 20% VAT.
Myth 2: "Landlords can claim 0% VAT on rental properties."
Reality: Rental properties managed as businesses are subject to 20% VAT. Only landlords living in the property can claim 0% VAT.
Myth 3: "I need to apply for 0% VAT."
Reality: The installer automatically applies 0% VAT if your property qualifies. No application needed.
How to Ensure You Get 0% VAT
- Confirm eligibility: Ensure your property is residential (not commercial or rental)
- Get written quotes: Quotes should clearly state "0% VAT - residential installation"
- Check invoices: Final invoices must show £0.00 VAT and reference the ESM VAT relief
- Keep records: Retain invoices for HMRC compliance (installers must keep records for 6 years)
What About Existing Solar Systems?
If you had solar installed before April 2022 and paid 5% or 20% VAT, you cannot reclaim the difference. However, if you now add a battery or expand your system, the new work qualifies for 0% VAT.
Future of the Policy
The 0% VAT policy is currently permanent with no scheduled end date. This provides long-term certainty for homeowners planning solar installations. The government views this as a key tool in achieving net-zero targets by 2050.
Combining 0% VAT with Other Incentives
You can stack the 0% VAT benefit with:
- Smart Export Guarantee (SEG): Earn 1-15p/kWh for surplus electricity
- ECO4 Grant: Low-income households may qualify for grants covering installation costs
- Home Upgrade Grant: Up to £10,000 for off-gas-grid homes
- 0% Finance: Many installers offer interest-free loans over 2-3 years
Final Thoughts
The 0% VAT policy has made 2025 an excellent time to go solar. With a typical saving of £1,000-£3,000 on installation costs, plus 25+ years of reduced energy bills, solar has never been more affordable or accessible.
Always ensure your installer is MCS-certified and provides clear invoicing showing 0% VAT. If a quote includes VAT on a residential installation, question it immediately—you may be dealing with an uninformed or non-compliant installer.
