Retrofit made simple for social housing
Renatus
In the UK there is over 2.5m social homes below EPC C with 28% of these EPC D or below. We believe that everybody deserves to live in a safe, comfortable, and healthy home and that’s why we have launched Renatus.
Renatus (or “born again” in Latin) supports social housing providers with a seamless, end-to-end retrofit service designed exclusively for social housing providers to deliver for tenants and achieve legislative requirements.
Upgrade your stock, improve tenant well-being, and deliver measurable savings with a single trusted partner.
Our step-by-step retrofit process
Survey and Assessment
Every retrofit begins with a detailed survey and assessment to gain a complete understanding of the property’s condition. We equip each home with advanced sensors that monitor temperature and humidity in real time, providing accurate insights into the indoor environment. By analysing this data, we can diagnose the root causes of issues rather than addressing only the symptoms. Our thorough examination process includes the following steps:
- Retrofit Assessment – An in-depth in-person evaluation of the property’s energy performance and areas for improvement. We also install sensors at the property for real time data capture of temperature and humidity to gather further insights and identify trends.
- Measured Survey – Precise measurements of the property to establish baseline data for accurate planning.
- Intrusive Survey – Comprehensive inspections that may involve exploring structural elements to identify hidden issues impacting the home.
This detailed approach ensures that every factor contributing to the property’s performance is considered before moving to the next stage.
Design and Specification
Once the assessment is complete, we develop a customized retrofit solution tailored to the specific needs of the property. We create designs that address identified issues while ensuring compliance with regulations and staying within set budgets. Where necessary, we work with trusted third-party products outside of our portfolio to deliver a complete, high-quality retrofit solution. This flexibility allows us to meet the unique requirements of any property while maximizing efficiency and minimising costs.
Supply and Inspection
Our commitment to quality doesn’t stop at design—we ensure every phase of the retrofit adheres to the highest standards through rigorous inspections. We perform these inspections at key stages of the process to validate that workmanship and materials meet our stringent criteria and align with the Renatus process. This proactive approach minimises risks and ensures a seamless retrofit experience.
Warranty and Post-Installation Support
After the retrofit is complete, we conduct post-installation testing to verify improvements in energy efficiency and overall performance. We issue certifications and comprehensive warranties for peace of mind, guaranteeing that the work meets both our expectations and regulatory requirements. Post-installation support ensures that the property continues to perform optimally, securing long-term benefits for both tenants and housing providers. The temperature and humidity sensors used during the assessment stage are also left within the property so you can continue to monitor the performance of the property and have complete peace of mind that the retrofit is performing to your expectations.
This end-to-end process ensures a systematic, transparent, and reliable approach to retrofits, enabling social housing providers to meet energy efficiency targets while prioritising tenant well-being.

“Dealing with one company, who offered the solution we needed, took away the stress from dealing with multiple suppliers. Renatus is a concept that streamlines the retrofit process and is a cost-effective way of improving our tenants’ homes. We couldn’t find this offer from any other manufacturer. The final product looks stunning, and we can’t wait to work on future projects with wienerberger”.
