Case Studies on Existing Refinancing Instruments for Energy Efficiency Services

This publication summarises the achievements, lessons learned and impact of the EU Peers project during its first funding period (September 2023 – August 2026), highlighting how the European Community of Practice has supported the development and scaling of One‑Stop Shops for residential building renovation.

Building renovation is a cornerstone of our energy and climate goals, but how can we accelerate progress? The H2020PROSPECT Handbook on One-Stop Shops (OSS) offers a practical guide to understanding and implementing these game-changing structures.

The 2026 EU Peers survey shows that One‑Stop Shops (OSS) for home energy renovation are rapidly expanding across Europe, mostly as local or regional services with diverse governance models. While almost all OSS provide guidance, fewer offer full end‑to‑end renovation support, and the biggest challenge remains converting homeowner interest into actual renovation projects. OSS operate at very different financial scales but rely heavily on public funding, and many are increasingly addressing energy poverty through partnerships with social actors. The next major step for the sector is scaling up, which will require stable funding, stronger institutional backing and better coordination to make OSS a mature, widely accessible part of Europe’s renovation ecosystem.
