Apply for Government-Funded Energy Efficiency Grants
Take advantage of available funding under ECO4 and GBIS Schemes to make your home warmer, greener, and more affordable to run. Book your free home survey today and find out which energy-saving improvements you could qualify for. The ECO4 scheme provides “whole-house” energy efficiency upgrades, such as new boilers and multiple insulation measures, while the Great British Insulation Scheme (GBIS) focuses primarily on single, less costly insulation measures to help more homes quickly. Both are UK government schemes administered by Ofgem, but they cater to different types of properties and households by offering various grant types to improve energy efficiency and tackle fuel poverty.
