Outcomes Over Outputs: Retrofit Redefined

30/06/2025

Retrofitting homes isn’t about tech or tick boxes — but about delivering outcomes that actually matter.

In this episode, Andy Sutton, Co-Founder and Chief Innovation Officer at Sero, lays down a bold challenge: define the outcome you want, measure it at the end — and keep it simple. From health to heat, retrofit must be judged by what it delivers for real people, not what it looks like on paper. 

Key takeaways: 

  • Retrofit must start with outcomes: health, affordability, comfort, and carbon reduction. 

  • Define success in plain terms — CO₂ levels, temperature, running costs — and measure it post-works. 

  • Separate the technical from the tactical — residents need clarity, not complexity. 

  • Poor ventilation and overheating are often missed, yet critical to health. 

  • Place-based, phased retrofit and early engagement build trust and uptake. 

  • Retrofit is a health intervention — physical and mental. Think safe, secure, joyful homes. 

  • Quality assurance can’t be a tick-box — it must prove the home performs. 

  • Andy’s ‘magic wand’ idea: include minimum warmth in rent to align incentives and protect health.
