The European residential renovation landscape is evolving rapidly, and One-Stop Shops (OSS) are increasingly emerging as a key mechanism for helping homeowners navigate the complexity of energy renovation projects. The latest findings from the second EU Peers survey provide compelling evidence that OSS are moving from innovative pilot initiatives to an established and growing component of Europe’s renovation ecosystem.
The newly published survey report, based on contributions from 76 organisations across Europe, offers valuable insights into how OSS are operating, growing and adapting to support Europe’s energy transition. The participants included 35 operational OSS providers and 41 organisations involved in supporting OSS development, such as energy agencies, public authorities, networks and policymakers.
A growing movement across Europe
One of the clearest messages emerging from the survey is the continued expansion of the OSS sector. Most of the surveyed organisations were established after 2020, confirming a significant acceleration in the development of integrated home renovation services across Europe. According to the report, the sector has evolved beyond isolated demonstration projects and is increasingly benefiting from supportive European policies and funding programmes.
This growth reflects the growing recognition that homeowners often require technical, financial and administrative support to undertake energy renovation projects successfully. OSS are helping to bridge this gap by providing guidance and coordination throughout the renovation journey.
Local roots, European impact
The survey highlights the strong local and regional character of OSS. More than 60% of respondents operate at municipal or regional level, allowing them to build trusted relationships with homeowners and tailor services to local market conditions and administrative contexts. At the same time, national schemes demonstrate that the OSS approach can be successfully implemented at different territorial scales.
This combination of local proximity and scalability is one of the defining strengths of the OSS model and an important factor in its growing success.
No single model for success
The report confirms that there is no single blueprint for establishing an effective One-Stop Shop. Organisations operate under a variety of governance structures, including public bodies, private companies, public-private partnerships, cooperatives and NGOs. This diversity illustrates the flexibility of the OSS concept and its ability to adapt to different policy objectives, financing arrangements and market environments.
However, despite their organisational differences, successful OSS share common characteristics: a strong local presence, integrated services, trusted relationships with homeowners and close collaboration with public authorities.
Turning interest into action
The survey identifies a crucial challenge for the sector: converting homeowners’ initial interest into concrete renovation projects. While OSS engage with large numbers of households, the transition from first enquiry to energy audit remains a critical bottleneck. Encouragingly, once households reach the assessment stage, renovation completion rates increase substantially.
This finding highlights the importance of continued efforts to simplify customer journeys, strengthen engagement strategies and provide personalised support throughout the early stages of decision-making.
Public funding remains vital
The results also underline the continuing importance of public support. Public funding remains the principal source of income for many OSS, particularly those operating within the public sector. Respondents stressed that stable and long-term funding is essential to maintain service continuity, ensure accessibility for homeowners and build confidence in the market.
The survey suggests that creating sustainable business models while preserving affordability remains one of the key challenges facing the sector in the coming years.
Tackling energy poverty through partnerships
An encouraging development highlighted by the survey is the growing role of OSS in addressing energy poverty. Around two-thirds of surveyed organisations provide tailored support to vulnerable households, primarily through renovation advice and assistance in accessing available subsidies.
The report finds that the most effective approaches combine technical, financial and social support through strong collaboration with municipalities, social services and community organisations. These partnerships are proving essential for reaching vulnerable households and ensuring that the benefits of energy renovation are accessible to all.
From pilots to scale
The survey identifies three key conditions for growth:
- stable funding,
- stronger institutional recognition and
- improved coordination between stakeholders.
Together, these elements could enable OSS to evolve from successful individual initiatives into a mature and scalable pillar of Europe’s renovation system.
