Support to Upgrade Your Home
Northern Ireland has some of the highest rates of fuel poverty in the UK. Many homes across the region still rely on oil heating systems and are inadequately insulated — meaning families are spending far more than they should to stay warm.
Government grant schemes are designed to change that. They provide funding — in many cases fully covering the cost — to upgrade insulation, heating systems, glazing, and more. The result: a warmer home, lower energy bills, and a reduced carbon footprint.
Whether you own your home or rent privately, BlueBuild Energy can help you find out what you’re entitled to and manage the entire process on your behalf.
