In order to achieve the European Commission’s long-term energy vision for 2050, it is necessary to dramatically increase the yearly buildings renovation rate. Deep retrofits, leading to over 60% of primary energy savings, will therefore be critical. But, as these investments can be expensive, new and innovative ways of financing them are vital. On-bill schemes represent a key innovative way of leveraging private finance for energy renovation of residential buildings and RenOnBill aims to make their uptake in the EU easier and faster.

In this aim, RenOnBill developed a roadmap to disseminate knowledge about the replication potential of on-bill schemes for the European market. This roadmap for replicating on-bill schemes has been drawn up by the RenOnBill project team to analyse potential barriers to on-bill replication and propose solutions that can lead to a more conducive national framework for on-bill schemes. 

The roadmap insights have been derived by the implementation of the project in four focus countries: Spain, Italy, Lithuania, and Germany. In each of these focus countries, project partners established national stakeholder platforms to inform the replication process of on-bill schemes at national level. In Spain, Italy, and Lithuania, three partner utilities formed part of the project consortium, providing hands-on insights into the particularities of replicating on-bill business models in their respective national context. 

The objectives of this roadmap are to: 

• Raise awareness for on-bill schemes;
• Disseminate knowledge on on-bill scheme replication in Europe, based on 3 years of research;
• Inform about different types of on-bill schemes;
• Point to the momentum for energy renovations in residential buildings that has started to build up at EU level;
• Lay out a path for the replication of on-bill schemes in the four RenOnBill focus countries Italy, Spain, Lithuania, and Germany;
• Explain relevant challenges and potential solutions for on-bill scheme replication in Italy, Spain, Lithuania, and Germany.

This roadmap aims to support policy makers, energy regulators and other representatives from the energy and financial sector to understand the replication potential of on-bill schemes and to influence decision-making with a view to innovative financing instruments for energy renovations in the residential building sector.  It will be a useful resource for energy utilities, financial institutions, policy makers, energy regulators, academia, and anyone interested in boosting the renovation rate of residential buildings in Europe with the help of innovative instruments to leverage private finance.
