Beyond its competence in the daily management of our large perimeter of sites, the Sirenergies firm allows us to optimize our contracts, through its expertise, its availability and its proactivity. The quality of their Pilott platform also improves our autonomy in the follow-up of this file.

Apart from the human relationship that we can have, working with Sirenergies is very clearly a price benefit. When the market opened up for businesses, our invoice prices were x3. Now, thanks to their support, we are able to go down to rates that are much lower, much more interesting.

Thanks to their rigorous analysis and their total independence in choosing the supplier, I was able to achieve a concrete saving of 6% on my overall bill. This result is all the more significant as it saves precious time, allowing me to remain fully focused on serving my customers and developing my point of sale.
