Turning data into impact: 

Measuring real-world retrofit outcomes    

23rd July 2026 | 11:00 - 12:00

Join us for an in-depth look at Switchee’s intervention analysis report and how it helps housing providers measure the real-world impact of property upgrades using property-level data. By comparing pre- and post-intervention performance, the report provides clear, evidence-based insights into thermal efficiency, helping organisations validate investment decisions, reduce mould risk, and better understand the impact of retrofit programmes on residents and homes.

In this session, Switchee's Dan Sotudeh and Izzy Henry will demonstrate how intervention analysis is being used in practice to evidence outcomes, strengthen accountability, and support data-driven decision-making across housing.

In this session, we’ll cover:

  • The challenges housing providers face when measuring retrofit impact and demonstrating value.

  • How Switchee’s intervention report works, including the methodology behind the insights.

  • How thermal performance and risk metrics can be used to evidence improvements in living conditions.

  • How robust, data-backed evidence can support investment decisions, reporting requirements, and stakeholder engagement

Register now to discover how Switchee data can help you better evidence and understand the impact of your retrofit interventions.
