We build the case, recover what you're owed, renegotiate your contract right after and schedule maintenance before winter. One bill, three answers: Defend, Optimize, Maintain.

Our model, with no grey areas

Transparency, spelled out in full

alloenergy doesn't sell energy or install panels. We qualify, guide and follow up — and we publish how we make money. A poorly rated supplier can still be a partner: we write it in black and white.

Frequently asked questions

What you're asking

Do you sell my data?+
No, never. You send explicit requests to declared partners, only for the purposes you've checked — revocable with one click.
Is it really free?+
The diagnostic and the first result are free, no email. On recoveries, our partners charge only on success.
How do you make money?+
On success for overcharges, for connecting you with declared partners, and for maintenance subscriptions. Everything is published.
Do you sell energy?+
Never. That neutrality is the condition of our independence — a poorly rated supplier can still be a partner, we write it in black and white.
Can I withdraw a consent?+
Yes, at any time and with one click from your client area. Every consent is time-stamped and kept as proof — never deleted, but revocable.
