A deep retrofit is a full upgrade of your home’s energy performance, often bringing it up to a BER A-rating standard. This includes improvements to insulation, windows, heating systems, ventilation and more, all carried out in one coordinated project.

We deliver deep retrofits through the SEAI One Stop Shop (OSS) programme, managing everything from grant applications to final installation. It’s a smart, future-proof investment in comfort, efficiency and sustainability, and we’ll guide you every step of the way.

Looking to make targeted improvements? From attic insulation and heat pumps to solar panels and window upgrades, we offer a full range of standalone energy upgrades for homeowners.

Whether you want to improve comfort, cut energy bills or reduce your carbon footprint, we’ll help you access SEAI grants, choose the right solutions and carry out the work to the highest standards.
