ECO Surv, the UK’s leading retrofit operations platform, has today announced a new strategic partnership with Sava (who are part of InfoShare+), aimed at strengthening the tools, support, and innovation available to Retrofit Coordinators, housing providers, and installers.
The collaboration will be launched with the integration of Sava’s trusted energy modelling technology into ECO Surv’s newly released energy modelling functionality. This marks the first step in a broader partnership between the two organisations, designed to deliver smarter, more efficient, and fully compliant retrofit solutions.
A Step-Change for Retrofit Coordination
The new Energy Modelling functionality, now live in ECO Surv, embeds Sava’s industry-trusted modelling engine at its core. This integration enables coordinators to:
- Access advanced RdSAP inputs for unmatched accuracy
- Capture richer data with Enhanced IOE for deeper insights
- Use smarter optioneering to instantly compare upgrade pathways
- Deliver projects end-to-end in one seamless platform, without external tools
Developed directly from customer feedback, the release reduces duplication, minimises errors, and empowers coordinators to deliver retrofit projects faster and with greater confidence in compliance.
A Strategic Partnership
While the integration represents a major technical milestone, ECO Surv and Sava are also committing to a long-term partnership. Together, the organisations will:
- Share expertise and data-driven insights to shape the future of retrofit delivery
- Strengthen the support available to coordinators, housing providers, and utilities
- Develop scalable, compliant solutions to tackle inefficiency and fragmentation
- Launch an Industry Innovation Network to accelerate collaboration and sector-wide innovation
This partnership combines ECO Surv’s leading platform with Sava’s deep expertise in energy performance, going beyond software to address the real challenges of retrofit coordination.
Nat Butters, CEO & Co-Founder of ECO Surv, said, “This integration is our biggest release yet—and only the start of our partnership with Sava. By embedding their trusted energy modelling into our platform, we’ve delivered what our customers asked for: accuracy, efficiency, and simplicity in one place. Looking ahead, our partnership will continue to drive innovation and strengthen the sector as a whole.”
Andy Flook, Director of Business Development at Sava, added, “We’re delighted to partner with ECO Surv. The integration of our modelling technology into their platform is a powerful first step, but equally important is the wider collaboration between our organisations. Together, we’re giving the retrofit sector a credible, future-proof alternative to fragmented systems—backed by compliance, trust, and innovation.”
