About Us

We are one of Ireland’s leading home energy efficiency & deep retrofit specialists. We believe in making the retrofit journey as simple and as straightforward as possible so that all you have to do is enjoy your new, cosy home.

Our specialist team of experienced industry professionals will take care of all your requirements and answer all your questions. We pride ourselves on our expertise, the quality of our work and the speed of our service. We believe you won’t get a faster, better quality service from anyone else.

We are able to offer you a far more comprehensive service than most contractors, as we are one of the very few companies in Ireland both approved for heat pump installation and NSAI registered for external wall insulation.

We also have the unique privilege of having a trained architect as company director who has technical knowledge and expertise in the deep retrofit process.

Our company is the choice of industry experts who wish to retrofit their own homes and we have had several such clients.

We will transform your house into an energy efficient home…
