JOT Energy


We offer an expert energy consultancy service for new and existing buildings, for both domestic and commercial clients, with almost two decades of experience.

As a country, Ireland has set some very ambitious targets for retrofitting by 2030, and the provision of SEAI grants and European funding has made it easier for this to happen. We are experts in this field and can help you to navigate your project in a fuss-free manner.
