BuildCert was established by Brendan Sidney, an experienced Energy Consultant and Retrofit expert. Our aim is to improve the energy efficiency of buildings and homes in line with the Ireland’s Climate Action Plan. We cut out the complexity of building upgrades for our clients, offering simple professional advise and tailored solutions based on individual needs. Every building is different so we carry out technical assessments before we offer advice on upgrades. This ensures that we can guarantee results for our clients.

Our multi skilled staff provide services nationwide for both the domestic and commercial sector. No job is too big or too small.  We are delighted to offer our services to homeowners, construction companies and everything in between.
