15 December 2025: Can landlords guarantee a healthy minimum indoor temperature and make retrofit pay back faster? In this episode, host and Healthy Homes Hub co-founder Jenny Danson revisits last winter’s Warm Rents pilot with Switchee's co-founder Adam Fudakowski.
The pilot, alongside Clarion, Yorkshire Housing and Places for People, funded heat to a baseline 18°C via fuel vouchers and smart thermostat settings, lifting average indoor temperatures by around 1°C and cutting relative humidity below the high-risk 60% threshold linked to damp and mould. The 18°C baseline aligns with NHS and World Health Organisation guidance for maintaining health in temperate climates.
