At NRG Assessments, we are committed to helping homeowners improve their Energy Performance Certificates (EPC) and reduce energy consumption. With the growing emphasis on sustainability, many government backed grants and incentives are available in 2025 to assist homeowners in upgrading their properties' energy efficiency. These upgrades not only improve the comfort of your home but also reduce energy bills and contribute to the UK's net-zero goals.
In this blog, we’ll highlight the key grants and incentives for energy efficiency upgrades, including insulation, heat pumps, and other measures, and explain how you can take advantage of them.
