The maximum grant is £2,500, but most households receive £1,200–£1,800
If you are looking for a cash grant to install solar panels in the UK, the answer depends heavily on where you live. The Home Energy Scotland (HES) scheme offers up to £2,500 for solar PV, but the typical award is £1,200–£1,800 depending on system size and property type (GOV.UK, 2026; Energy Saving Trust, 2026). For England and Wales, the primary support is the Smart Export Guarantee (SEG), not a grant, this section clarifies the distinction upfront. Northern Ireland has a separate NI Energy Advice Service grant, capped at £2,000 for solar PV (NI Energy Advice Service, 2026).

Who qualifies for a solar panel grant in 2026
Grants are means-tested: only households with a gross annual income under £34,000 (England/Wales) or £26,000 (Scotland) are eligible for the main schemes (GOV.UK, 2026; Energy Saving Trust, 2026). Owner-occupiers only, tenants and landlords of private rentals are excluded from the grant, though landlords may access the separate ECO4 scheme. Property must have an EPC rating of D, E, F, or G to qualify for the grant-funded installation; homes rated A–C are ineligible (GOV.UK, 2026).
The direct answer to “solar panel grants uk”, there is no national grant, but Scotland and NI offer targeted schemes
England and Wales have no universal solar PV grant; the main support is the Smart Export Guarantee (SEG), which pays for electricity exported to the grid, not upfront costs (GOV.UK, 2026). Scotland’s Home Energy Scotland scheme provides a cash grant of up to £2,500 for solar PV, plus a loan for the balance (GOV.UK, 2026). Northern Ireland’s NI Energy Advice Service offers a grant of up to £2,000 for solar panels, with no income cap but limited to first-time installations (NI Energy Advice Service, 2026).
How to verify your installer is certified for a grant
All grant-funded solar installations must be completed by an MCS (Microgeneration Certification Scheme) certified installer, check the MCS Installer Directory (MCS Installer Directory, 2026). The installer must also be registered with TrustMark for government-backed schemes; verify via the TrustMark website (TrustMark, 2026). For SEG eligibility, the installer must provide an MCS certificate and a valid Energy Performance Certificate (EPC) for the property (GOV.UK, 2026).
How to choose a solar panel installer
How to confirm your eligibility before applying
Step 1: Check your EPC rating online via the GOV.UK EPC register, you need a rating of D or below for most grants (GOV.UK, 2026). Step 2: Verify your household income against the scheme’s threshold using the EST income calculator or the scheme’s own eligibility tool (Energy Saving Trust, 2026). Step 3: Contact your local energy advice service (Home Energy Scotland, NI Energy Advice Service, or your regional ECO4 provider) for a pre-application assessment (GOV.UK, 2026).
What the grant covers and what it does not
The grant covers the cost of solar PV panels, inverter, and installation labour up to the stated maximum; it does not cover battery storage, solar thermal, or structural upgrades (GOV.UK, 2026; NI Energy Advice Service, 2026). Battery storage can be added via a separate interest-free loan (Scotland only) or through the ECO4 scheme for eligible households (GOV.UK, 2026). The grant is a fixed amount, not a percentage of total cost, you pay the difference between the grant and the installer’s quote.
How to apply step-by-step
For Scotland: Apply online via Home Energy Scotland or call their helpline; you need your EPC, income details, and a quote from an MCS installer (GOV.UK, 2026). For Northern Ireland: Contact the NI Energy Advice Service for a referral to an approved installer (NI Energy Advice Service, 2026). For England/Wales: No grant application, instead, get an MCS-certified quote and register for the SEG with your chosen energy supplier (Ofgem, 2026).
