Who this is for

The distribution layer 150+ brands don't have

Energy Utilities
Match subsidy-eligible customers with qualified installers in their area. Structured data beats manual referral lists.

Certification data compounds.
Networks don't.

Every new installer certification issued, every F-gas renewal processed, every MCS registration updated feeds into HeatIndex automatically. The data asset grows with the market. By 2030, the EU needs 50 million heat pumps operational. Someone needs to connect them all to the right installers.
