They trust Hellio

gilles-deschamps-l-imprimerie

We are very satisfied with the work carried out by Hellio, which helped us to finance a large part of this investment and make significant energy savings, with a beneficial impact on the environment.

Gilles Deschamps, Operations Manager at L’Imprimerie

Hellio has a thorough understanding of the potential for energy savings and the actions that can be taken to earn EEC. Insulating the terrace and lagging the hot water networks have resulted in energy and operating savings.

Damien Kocik, Investment Director, Hôpital Necker Enfants Malades (Necker Children Hospital)

We wanted to modernise and expand our refrigeration areas at our 3 sites. Hellio supported us and reassured us at every stage (understanding, financing, etc.). The EEC bonus financed 70% of the total cost of the work.

Pierre Leroy, manager of Sarl Leroy

The work went very well. Switching from fuel oil to pellets means that my house is well heated and I save €1,200 a year. What’s more, it cost me next to nothing, and it’s better for the environment!

Jérémy, private individual

It really was a welcome surprise to see projects completed with a bill of €0, with no payment. We’re already starting to feel the energy savings. The work has also improved the health of the communal areas.

Karen Plisson, co-ownership manager

Mickaël Schmith

25% more people hired, increased turnover and maintenance contracts: the partnership with Hellio has enabled us to develop our business significantly, with quality leads. Our contacts are attentive and highly responsive.

Mickaël Schmith, Manager of LMD Calorifuge and LC Thermic

Hellio enabled us to quickly invest in the renovation of the town hall and gymnasium. Without their support, these projects would have taken a minimum of 3 to 4 years to complete.
