"I bought my house in 2020 knowing that it was very poorly insulated, as it has an F rating on the energy performance certificate. When I looked into external thermal insulation, I realized it was going to be expensive. But thanks to Hellio and Freitas, who advised me and recommended the work, I was able to benefit from substantial financial assistance to carry out a major renovation."
