The HP SUBSCRIBE project aims to scale up the deployment of high-performance heat pumps in leased commercial and public buildings through an innovative Heat Pumps on Subscription (HPoS) business model. This service-based approach tackles the main barriers to heat pump adoption:

• The landlord-tenant split incentive,
• High upfront investment costs, and
• The complexity of replacing fossil-fuel heating systems

The project brings together authorities, building owners, financiers, manufacturers, and stakeholders to validate and demonstrate the model through pilot initiatives in France, Austria, Greece, and Ireland.

HP SUBSCRIBE will also explore supportive regulatory mechanisms, including white certificate schemes and demand response programs, to enhance financial viability and drive large-scale adoption.
