Am I eligible for free or subsidised solar panels in the UK?

You may qualify for free or subsidised panels if you are in a means-tested lower-income household in an energy-inefficient home. Whatever your income, you can access 0% VAT and low-interest loans.

Route 1: 0% VAT, for everyone

Until 31 March 2027, residential solar and battery installs carry 0% VAT. Your installer applies it at the point of sale, with no form to fill in.

Route 2: grants and subsidised upgrades

ECO4 supports energy-efficiency upgrades, potentially including solar, for means-tested households with an EPC rating of D to G. The Warm Homes Plan offers fully funded upgrades for low-income households, with low-interest loans open to everyone. Check your EPC rating on the government register first.

Route 3: the Smart Export Guarantee

Not a grant, but payments for surplus power you send to the grid. Your system must be MCS certified. Available in England, Scotland and Wales.

Check your options in three steps

• 1. Look up your EPC rating
• 2. Check your household income against current thresholds
• 3. Confirm your installer is MCS certified

Frequently asked questions

Can I get 100% free panels?

Only if you are a low-income household in an eligible band. Most homeowners will not qualify, but nearly everyone benefits from 0% VAT.

Does a grant or loan change how much I save?

No. Funding changes what you pay for the system, not what it earns you.

All figures are modelled estimates for typical UK rooftops, not guarantees for any individual home. Rules, funding and eligibility can change, so check current government and supplier guidance before deciding.
