ECO4 (Energy Company Obligation): Funds energy efficiency improvements — including solar panels — for households on qualifying benefits or with low EPC ratings. Delivered through energy suppliers.
Boiler Upgrade Scheme (BUS): Provides grants for replacing gas/oil heating with heat pumps. Check gov.uk for current grant amounts, which are revised periodically.
Great British Insulation Scheme: Supports insulation improvements that make homes better suited to renewable heating. A well-insulated home benefits more from solar and heat pumps.
EV Chargepoint Grant (OZEV): Provides up to £350 toward a home EV charger for eligible properties. Check gov.uk/electric-vehicle-chargepoint-grant for current eligibility.
Smart Export Guarantee (SEG): Not a grant but an income — energy suppliers must pay you for solar electricity exported to the grid. Compare SEG tariffs to maximise returns.
