One-stop-shop (OSS) business models offering integrated renovation services, making renovation more affordable and feasible, are a requirement of European Union policies aiming in energy efficiency in buildings. The present paper offers an ex-ante (pre-implementation) and ex-post (post-implementation) evaluation of 37 OSS business models currently operating in the EU renovation market. The evaluation was performed using eight indicators that evaluate key factors in a business model followed by interviews with representatives of each of the examined OSSs. Findings indicate meticulous design and execution, with alignment between pre- and post-implementation evaluations, albeit with a lack of rigorous competitor analysis. While OSSs generally delivered expected value propositions, some struggled with clear communication and initial market assumptions, emphasizing the need for customer-centric strategies and adaptability to market dynamics for sustained success. The study also provides suggestions for future OSS development, which include comprehensive competitor analysis, enhanced communication strategies, and strategic partnerships to ensure long-term sustainability and success.
