The incentives, rebates and finance options currently available in the UK include:   Energy Company Obligation (ECO4) ECO4 is designed to reduce heating costs and improve energy efficiency in domestic settings, specifically targeting low-income and vulnerable households. By upgrading homes to be more energy-efficient, the scheme aids in reducing carbon emissions and fighting fuel poverty.   Home Upgrade Grant (HUG) The Home Upgrade Grant (Phase 2) provides no-cost energy-efficient improvements for homeowners who find it difficult to afford their heating bills and maintain a warm home in winter. These improvements, offered at no charge, are designed to help residents warm their homes more effectively, reduce energy use, and control heating costs.   Boiler Upgrade Scheme (BUS) The Boiler Upgrade Scheme helps subsidise the cost of replacing old fossil fuel heating systems with more sustainable alternatives like heat pumps or biomass boilers. These fossil fuel systems include those powered by oil, gas, electricity, or LPG (liquefied petroleum gas).   The Smart Export Guarantee (SEG) The Smart Export Guarantee rewards individuals or businesses for exporting surplus electricity generated from renewable sources back to the National Grid. It applies to various renewable technologies, including solar panels, wind turbines, micro-CHP, hydro, and anaerobic digestion to boost the use of renewable energy and reduce carbon emissions.
