Grant and scheme eligibility
Check which UK solar grants and schemes you may be eligible for. This is a quick guide — always check the official scheme for full criteria.
0% VAT on solar
All residential solar installations are zero-rated for VAT until March 2027. Saves ~20% on the install cost. Applied automatically by your installer.
Smart Export Guarantee (SEG)
Not a grant but guaranteed income — energy suppliers must pay you for electricity you export to the grid. Requires MCS-certified installation.
Next steps for you
Your EPC rating means you are unlikely to qualify for grants targeting fuel poverty. Focus on the 0% VAT saving (automatic on your installer quote) and maximising Smart Export Guarantee income from a well-designed system.
Frequently asked questions
Can I claim a grant AND the 0% VAT saving?
Yes. The 0% VAT rate is automatically applied on the invoice and does not count as additional funding. You can stack it with ECO4, HUG2, or any regional scheme.
How long do grant applications take?
ECO4 applications typically take 6-12 weeks from initial assessment to installation. Warmer Homes Scotland is similar. HUG2 can be faster if your local authority has remaining budget. Plan ahead if you want solar before winter.
Will applying for a grant affect my benefits?
No. Home improvement grants are not treated as income for means-tested benefits. They are classified as capital improvements to your property, not financial support.
What documents do I need to apply?
Typically: proof of address, proof of ownership (or tenancy + landlord permission), recent benefits letters if means-tested, and your current EPC certificate. The installer usually handles the paperwork for you.
Are grants taxable income?
No. Residential energy efficiency grants are not taxable. If you sell your home later, the improvements may affect your capital gains calculation, but the grant itself does not create a tax liability.
How this works
Several UK schemes can fund part or all of a solar installation for eligible households. The main ones are ECO4 (England, Wales, Scotland), the Home Upgrade Grant (HUG2, off-gas-grid only), Warmer Homes Scotland, Nest Cymru (Wales), and the 0% VAT rate available to everyone.
Eligibility depends on three main factors: home ownership status, EPC rating, and region. The calculator filters the scheme list based on your selections and highlights which ones you may qualify for.
All grants have additional criteria (income thresholds, benefits status, property type) that this tool cannot fully verify — always check the official scheme details before applying.
Things to consider
- •ECO4 funding depends on your energy supplier having budget remaining — apply early in the scheme year.
- •The 0% VAT rate runs until March 2027 and applies automatically on your installer quote — no application needed.
- •Grant applications can take 6-12 weeks. Factor this into your timeline if you need solar before winter.
- •Scheme eligibility can overlap — many households qualify for ECO4 AND the 0% VAT rate simultaneously.
