If you work in energy renovation (insulation, heat pumps, solar panels), you know: your numbers get blacklisted faster than any other sector. Here's why and how to survive.
Why Energy Renovation Is Under Scrutiny
Damning Numbers
- 28% of Bloctel sanctions concern this sector
- 45,000€ average fine (highest across all sectors)
- 375,000€ record fine in 2024-2025
- Numbers blacklisted on average in 3-5 days of intensive prospecting
What You Must STOP Doing
Mass Cold Calling
Calling homeowner files bought on the market leads to near-systematic reporting.
Manipulative Scripts
Phrases like your grants are expiring are often misleading and generate immediate reports.
Strategies That Still Work
Strategy 1: Local First
- Local number (landline) instead of mobile
- Local SEO: Google My Business
- Local partnerships: city halls, real estate agencies
Strategy 2: Qualified Inbound
Attract prospects instead of chasing them with SEO, online simulators, and educational content.
Strategy 3: B2B as Relay
Prospect prescribers (property managers, architects, banks) rather than individuals. B2B isn't subject to the same restrictions as B2C.
Protecting Your Numbers
| Use | Numbers | Max volume/day |
|---|---|---|
| Inbound lead callback | 2-3 landlines | 25/number |
| Warm prospect follow-up | 1-2 dedicated | 15/number |
| Support/Customers | 1 main number | Unlimited |

Conclusion
The energy renovation sector pays the price of past abuses. Legitimate companies must radically differentiate from scammers by prioritizing inbound and local strategies.
