SuSy House is a digital platform that helps housing providers and local authorities plan, deliver, and track residential retrofit projects through resident engagement, project management, and real-time data.

SuSy House is a social tech company helping to accelerate domestic retrofit across the UK. Their free-to-use app gives homeowners tailored advice on improving their home’s energy efficiency, while their tools support local authorities, housing providers and installers to plan and deliver retrofit at scale.
By streamlining communication, tracking retrofit progress in real time, and surfacing actionable insights, they remove many of the practical and logistical barriers that often stall decarbonisation efforts. Their aim is to embed SuSy as the digital backbone of retrofit delivery, ensuring every upgrade contributes meaningfully toward carbon reduction goals.
On their membership with SWM, they say:
“At SuSy, we see our role as a key enabler in the region’s journey to net zero by 2050. Our contribution lies in providing digital infrastructure that supports more efficient, transparent, and scalable retrofit delivery.
Through our resident engagement portal, project management tools, and insights platform, we help local authorities, housing providers, and contractors make data-driven decisions, improve tenant engagement, and accelerate retrofit uptake across tenures.”
