Here you'll find answers to the most common questions about our retrofit solution, designed to help social housing providers meet energy efficiency targets and improve tenant wellbeing. From funding support to performance guarantees, we’ve covered the essentials to help you understand how Renatus works, what it offers, and why it’s a trusted solution for scalable, data-driven retrofit.
What does “Renatus” mean?
Renatus means “born again” in Latin. We chose this name for our offer as we give a new lease of life to existing properties through cost effective retrofit measures, designed to meet the necessary EPC certificate.
Does Renatus support funding applications?
Yes. Wienerberger connects providers with specialist funding advisors to assist with the complexities of funding applications.
Can Renatus guarantee an EPC C or above?
Yes. Renatus is purpose-built to help social housing providers meet or exceed EPC C standards. We guarantee that we will meet the EPC rating agreed with the client when the Renatus Design and Specification Package is issued.
What kind of monitoring is included?
Sensors are installed to track performance indicators such as heat loss, humidity, indoor air quality, and tenant comfort—providing transparency and proof of performance.
Is Renatus scalable?
Absolutely. Every home is different and that is why we treat every property on a case-by-case basis, as opposed to designing by architype. Whether you're upgrading a small number of homes or your entire housing stock, quality and performance is guaranteed throughout the Renatus process.

Why are you collaborating with Liverpool John Moores University?
wienerberger is collaborating with Liverpool John Moores University (LJMU) in a pioneering “living lab” initiative to instill trust in it’s data driven approach to retrofit. The University is performing a study on three houses from different eras (1920s, 1970s, 2010s) that have been retrofit as part of the Renatus process, capturing real-time data on energy, humidity, temperature, U-values, and more, to measure performance. Expectedly, the results show a marked improvement in the thermal and operational performance of the three homes, meeting the agreed EPC certificates.
How does Renatus help reduce fuel poverty?
By improving insulation, airtightness, and energy efficiency, households require less energy to stay warm, lowering bills and reducing the risk of fuel poverty.
Is tenant disruption minimised during retrofit works?
Yes. The process is designed to be minimally invasive, with careful planning and scheduling. We work with you to provide clear communication with tenants to help manage expectations and reduce inconvenience.
How does Renatus contribute to Net Zero targets?
By drastically reducing the carbon footprint of existing housing stock through energy efficiency upgrades and integration of renewable systems, Renatus supports national Net Zero housing goals.
