The Home Upgrade Grant (HUG) is a UK government initiative that provides financial assistance to low-income households in England for energy efficiency improvements and low-carbon heating systems. The program, which targets off-the-grid homes with Energy Performance Certificates (EPC) rated D to G, will provide up to £630 million in grant cash to successful local authorities for the HUG 2 phase, which will run from April 2023 to March 2025. The key objectives are lowering energy bills and assisting in the transition to net-zero emissions. Eligible homeowners can get up to £25,000 in funding for customised installations that include energy-efficient measures and low-carbon heating systems like low-temperature heat pumps. The programemphasises a personalised approach, ensuring that modifications are tailored to the specific needs of individual residences. Importantly, low-income homeowners face no financial hardship, whereas private and social landlords must contribute a minimum of one-third and one-half of the entire upgrading cost, respectively. HUG is committed to reducing fuel poverty and facilitating a smooth transition to a more sustainable and energy-efficient future.
